I watched the video to see what you were doing. When you first started talking about installing an outlet where the switch was, I thought you were going to run a Suicide Cord to it from a generator. I'm glad to see I was wrong.
I just did this to my furnace, which one of your past videos, gave me the idea. I bought an Anker back up supply for the job from Amazon. I wired mine a little different. I used a combo switch and outlet where the switch was. I made it so the switch controls the combo outlet, all in the same electrical box. Then, I ran my pigtail wire to the furnace. What I'm doing differently is, leaving the furnace plugged into the backup, all the time, and the back up is always plugged into the switched outlet. Been using this for weeks. For me, if the power goes out, and I'm away for some hours, it's all done automatically. I ran the furnace, solely on the backup after I did the install. It ran for 6 hours, perfectly, and I still had 75% of my battery left. The Anker model also has an app for my phone, so I can always check and see what's happening at home. Worked perfectly. Really happy I did this. Did not know about the bonding plug issue, but fortunately, mine works fine without it.
@@jmhescher I bought the Anker Solix C1000 (X). It works fantastic. I bought it from Amazon when they had their Prime Days thing going on. It was a little over 500 bucks, and when the power goes out, it will be worth every penny.

Just a couple of code pointers. That outlet needs to be 15, not 20 amp on a 15 amp circuit. That also needs to be a dedicated (single) outlet or you will need a GFCI. (concrete floor = damp location) That pigtail connections needs to be OUTSIDE the cabinet so you don't void the UL listing of the appliance. (temp rating of internal wire) Last but not least, the NEC will call for a service switch at the unit even though a cord / plug qualifies as a disconnect. This will be under the headings of permanently installed appliances. Probably best to swap out that 2x4 electrical box for a 4x4 and do it all in one place. Store the excess pigtail behind the BX cable in a loop.
@@billy-go9kx which is why most HVAC guys don't have a full grip on the NEC, despite their license covering all the wiring near a unit. (but not into the breaker panel)
@@leeroth5604 Yes, you could but for a DIY that work box is getting a little crowded with the extra wires and restraints. It has no room for side entry with that device in place and the screws will be hitting when trying to secure that device. 4x4 box with a mud ring is the way to go.
Truthfully with all the different power sources available in different price ranges, every home should have an Interlock or Manual Transfer Switch installed. But what you're trying to do, just install an Interlock on your main control panel. It's much safer, legal and doesn't require any modifications to your furnace.
Another great video. Here in Texas countryside we don’t have gas so our furnace is all electric meaning 240VAC. So I would power that with a whole house backup or maybe a portable generator like the Anker Solix 3800 which provides 240VAC split phase. In reality I will likely have a critical needs panel until I can cover the whole house with battery backup but that is another story. It is nice to have options. Thanks again for your videos. I always learn something. All the best from north Texas!
The nice thing about these Portable power stations (I have the EcoFlow Delta 2 Max) you can plug the Portable Power station into 120VAC source and leave the the furnace plugged into the Power station 24/7 as most of them incorporate a "Pass-through" feature where whatever is plugged into the Power station will be powered by the grid power while it is also keeping the Power stations battery charged. This way you do not have to get up in the middle of the night to plug the furnace into the power station as it automatically switches to battery when needed. I wish they had a feature for my RV's LP, which ALWAYS empties a tank between midnight and 5 AM and it is cold outside. LOL
1,000 Watt inverter method is the one posted in a previous video is the one I want to go with. Pigtailed to my Chevy 2500HD Duramax. Also, I store my Deep Cycle RV batteries in my garage in the winter.
My first attempt at being able to supply critical items like my furnace and well pump (120v) was a manual transfer switch: I cut the power wires going to them and inserted male and female plugs inline. In the event of an emergency, I manually ran an extension cord from my generator to the basement and switched to it supplying the power. Never had to use it tho. Since then, I’ve added an inlet box for my generator and tied it to my breaker box with an interlock.
That’s a great way to get an essential backup. Our setup is with a 120V Reliance TF151W 15A Easy/Tran Furnace Transfer Switch. Hardwired in and attached to the furnace and UL listed and inspected/approved by county. Takes an extension cord outlet as input. Had it on the old furnace and was essential last winter when had ice storm, sub freezing temps, and 70 mph winds that took out power for an extended amount of time. Used a Ecoflow Delta 2 as a buffer between our Honda EU3000is Gen and the furnace and other sensitive electronics like routers, cable modem, tv, etc. Extended cold weather took out old furnace heat exchangers so Gen backup transferred to new furnace. First time we needed to run generator overnight in 15 years we had Gen.
Did this modification during the Texas Freeze of 2023, I found a previous video of yours. It was awesome to have some normal comfort during that outage. quick and easy, when grid power came back, unplugged from generator and plugged back into grid. I used a switched outlet so that I can still switch on and off if needed.
If the wire coming into the box is both 14 gauge and also fed from a 15 amp breaker then it doesn’t make sense to use the outlet shown which is for 20 amp service.
@@rupe53 it’s a simple issue. The 20 amp outlet allows you to plug in a 20 amp load device. That will trip the 15 amp breaker. You shouldn’t mislead a person to think the circuit supports 20 amps when it does not.
@@neilbrookins8428 and that's the reasoning behind the code not allowing a 20 amp outlet on a 15 amp circuit. BTW, a 15 amp breaker will run overloaded for many minutes before tripping. The problem will eventually be failing insulation due to heat cycling if it gets used that way.
Very well could have but it might get a little crowded. Changing from a single gang box to a double gang with a single outlet cover would fix that as well.
Hey thank you for this video and all that you do for DIYers, just wanted to get some ideas on your approach doing this having a transformer on the opposite side of the socket
Hi when you install your own diy hvac system iv seen on other video it might not be a good idea to use stay brite 8 the acid from the flux will mix with the refrigerant and cause a compressor failure unless you flush out the line sets after your done using stay brite 8.
Question, If you don't have a power station, can you use a portable gas generator outside and do you still need the bonding plug. Thanks for such a good informational video, makes it really easy to understand.
@@diyhvacguy No, most gas generators are already bonded so no plug is needed. Also, most 120v outlets on a gas generator is gfci and you CAN’T use a bonding plug on a gfci without tripping it.
My furnace was hard wired. It didn't have a switch. I just opened up the furnace and the junction box inside and pulled the wires to the outside of the furnace. Installed a box and outlet on the end of the house wiring. Then, I added the pigtail and the connection of the pigtail to the furnace is in the junction box inside the furnace. I just did this today in advance of this evening's big windstorm. So, I shouldn't lose power now.
I know people hate me for always pointing this out. Anyways at 3:25. So you check the tester to see if the tester is working on a known live source, then check if what you are working on is off, BUT after seeing it is off you check the tester again to see if it did not break. It is more or less standard for how to test if something is dead. I have seen once the tester break after checking it worked then on what should of been dead and someone got shocked.
Thanks for the video. So much better than the “widow makers of the past that I had to learn to make work. But I am much older so I should know more now. Never thought of doing this method. But I gotta figure out my situation with a gas mounted furnace that’s completely outside. Hmm. I shall find a video. It’s a weird house I got and with all the outside venting ish by looks. I know how the house was originally designed in the 60s and how they decided to do the design as a single home they prob ever built with what little money they had and never meant to sold until both died. Things like design from the foundation to to the roof in 70 years amazes me.
Interesting about the furnace needing bonded neutral. Also interesting that a portable power station isn't bonded. A little info on how to tell the difference would be helpful. Bonus: Making your own bonded plug is super easy.
Excellent video! I have a heat pump, but only use the "emergency" gas setting. I'm confused because I only have a hot and a neutral wire supplied to the unit. Can this still be done?
Is the bonding plug necessary if the power station is plugged in an outlet? I asked because I noticed my power station has no ground stand along; but grounded when plugged in. Thanks Great video btw!
Probably best to use a single outlet (not duplex). Any "inspector", rightfully could point out that the second outlet invites someone to wrongfully plug something in to what is required to be a single use furnace circuit. A well made, old style, twisted together wires with a well tightened and taped wire nut IS THE BEST most reliable wire connection
It's actually common to have an outlet for a condensate pump with AC or a condensing furnace. The code violation will be a 20 amp outlet on a 15 amp circuit. BTW, while a plug is ok by code as a disconnect, furnace code will still call for a switch. IOW, he probably needs both.
@@rupe53 Thank You. I have a 80% furnace and do not have any condensate pump/ condensing furnace experience. I Am of the opinion that it is too much "complicated efficiency" for stand alone reliability in these times. I too noticed the 20 amp outlet and 14 gauge cord and circuit wiring? so a switched outlet - single or duplex as indicated?
I strongly recommend you use nothing but 3M electrical tape. It guarantees the highest quality. We use it for all connections on railroad signals in awful environments and it stays attached and remains pliable.
What kind of gas line/fitting did you use in this installation? BTW I used your videos, got my technician license and saved $14,000 installing a hybrid 4 ton heatpump/gas furnace by myself! Thank you so much!
It’s a quick connect that is typically used for gas grills. Because this is in the middle of my garage I didn’t want to out in a permanent one so this works great. Obviously not up to code for a permanent installation.
Love the video. Thanks for the info! Heads up, Anker had a recall on a few of their powerbanks at the end of September 2024. Check out the recall notice before you purchase. I have an Anker power bank, and mine is fine.
Thank you for your informative and easy to understand videos. I have set up y furnace as you instructed in your video. I have not tested it yet as I am trying to figure out a battery (inverter) size to buy for this purpose. I do have a Honda generator that I can plug into the lighting panel but it is larger than I would need to just run the furnace for a short period of time for emergency heat. Any suggestions on a video to recommend the best battery (inverter) brand and size to use to run the furnace in an emergency?
Inverters attached to a car usually produce "dirty power" -- NON-pure sine wave. Can this effect the sensitive control board or possibly other components????
It's better to have the switch, and have the switch run to an outlet on the wall from the start. If this is not the way it's already wired, then I guess this is a good fix, but I'd rather have a furnace switch and a wall outlet be code. Then you can simply put a UPS in, and you're good to go in emergencies. A decent UPS should be able to light a furnace for weeks of a power outage. Generators can't be indoors and require setup and possibly starting fluid to get going if they've been on ice for a while.
if you have a gas furnace, then look around it. You'll find a little box with a switch that says "auto"/"manual. When power goes, just push it to "manual," and your furnace will work, no control over the thermostat but heat in the home till power comes back. Much easier than playing with the system.
My husband and I had someone do this for us for 50 dollars but going to a Honda generator outside, I must mention the local furnace company wanted 500 dollars for this job.
@@josephpadula2283 the part about a screw in fuse likely dates back to at least WWII and never got removed. (maybe even the 1920s) The reason was adding central heat to a home without adding an extra circuit to the fuse box. IOW, tying into an existing power feed in the basement and making your own branch line. There was actually a combination switch / fuse base made to fit a 2x4 box with a small flip-up cover for the fuse. (have one in my house) Kinda cute but short lived because many just installed a ceramic bulb fixture and landed the fuse there, next to the switch box. Screw in fuses have the same thread as a lightbulb.
Nice idea man. OK if you have a "battery power station" but just with a actual generator it would have to be outside. How much power/current does the average furnace draw? If it's that 230w then the battery amp draw is 10 times that or about 20A. I know that usually the gel-cell batteries (like the ones for UPS backup) are shit. only last perhaps 2 years even if not used, and are expensive to replace.
read your data tag then figure out if the watts are combined or separate for the heater and blower. Most will be in the 200 - 400 watt range. That's 2-4 amps total. An oil or gas boiler will be in the 2-3 amp range, including the circulators.
There are all types of thermostats out there and different wires coming out of the wall from the A/C. How do you know if you are buying the right thermostat?
Hi Dave: Thanks for these "keep your furnace going" videos. Im very interested in this "Bonded Plug" fix, as Ive got a problem after having done a similar install following your previous videos. I watched and installed the “plug,switch, pigtail” setup in your 12-9-22 video as you directed, then I upgraded following your methods in the “EX Generator Switch” video of 2-24-23. I saw you used the Ecobee thermostat at your house, so I purchased and installed that too. When I tested for each setup, I confirmed functions. But, after an actual outage, and currrently using the EZ Transfer Switch setup, the furnace ran perfect off my Ecoflow Delta 2, and after a few minutes, the flame kicked off as expected based on the thermostat setting. However…the furnace fan never shuts off!! It runs on and on. So I try again. I unplug everything, let temp drop below the 70 degree setting, set furnace to 70 to call heat, the furnace kicks on again, fan comes on as usual, house warms to 70, then flame goes off as expected, and again, the fan never shuts off! The Delta 2 keeps getting drained! I reviewed that I installed to your specifications, so Im confused. Could the "Bonded Plug" be tha answer for this problem? Or would u suggest I look in another direction? Thanks.
The thermostat likely has a setting for the fan to either be on ‘auto’ (running only when heat or cooling is called for), or ‘on’ (constantly running). I helped a neighbor set up a different smart thermostat and this option was in the settings instead of being selectable from the main screen. Does your furnace fan always run while on utility power also?
@@Tvar7531 thanks for the idea, but no, the fan shuts off after the flame runs it cycle and the heating element gets cooled off. If it was always on, I wouldnt have thought something was "wrong". I wish it was that easy.
Nice vid. You know, what surprises me is that the furnace only needs 250 watts to run. And that is not much. Kinda like 3 old fashioned light bulbs worth of power.
You should have just installed that cable clamp in to the junction box and made the termination inside that.. Done and done. This hurts my head. The idea is on point though.
Can you also do this if your switch is on the wall, away from the furnace? I'm trying to wrap my head around how the wiring would work. Maybe after coffee.
lol coffee is always important. So it would be extremely easy. All you’d do is kill power at the breaker, remove your switch as well as the conduit that runs from your switch to the furnace, and then simply install the outlet where the switch was. Then you’d just put the pigtail in place of the conduit! I could probably do a video on this but I’m not sure how many furnaces would be oriented this way. Cheers
@@diyhvacguy Thanks, that makes sense. You mentioned something about not having the pigtail too long. The distance up the wall and over the ceiling and down to the furnace is probably longer than the 9' pigtail. Assuming I get a longer pigtail, would you be concerned about that longer length? Thanks a ton!
@@diyhvacguy I think I'm overthinking this. Couldn't I just leave the wire in the conduit, and use a short pigtail where it terminates in the switch box to then act as the plug after I change the switch to an outlet?
This is a very good video and something we want to do. The power in our city is very dependable as we have had maybe two outages in the 25 years we have lived here. However, we do need to be able to power our gas furnace in the event of an outage during the winter. Do you have any idea how much it should cost to have an electrician do this work that you showed in the video?
Probably 300-500 if I had to guess. Maybe less. The great part is it’s 100% reversible should someone say it’s “not up to code”. I’ve seen so many homes here in Utah with an outlet and a plug just like this and most inspectors would have no objections to it
Can you do this with an electric furnace? I live in a mobile home and have a DOWNFLOW/UPFLOW ELECTRIC FURNACE MODELS: EB SERIES. I use a 12,500 watt generator. Can I do this with the furnace I have? Do generators need that bonded plug? With an all electric home when the power goes out I'm pretty well Boinked.
Great idea 💡💯💡 as Always 👍. 8 years ago when I installed a gas self igniter Heater on the Wall.... And did Convertion run on Natural gas on the GENERATOR. Everyone in my Family Complained about it and made a lot of Bad Comments. Why this and why that❓❓ 2-years Later, We we had Winter storm and ice and Power outage. Many people were moved to Hotel and some Old people were dead without electricity. Then everyone in my Family said to me " You are Smart guy and always prepared"... People in General they don't See and don't believe. In my mind I called them what a Clueless and Stupid people.
I can see that the original furnace before modification was fed by a metal conduit and rated for high temperature. But the post modified feed is plastic with a possible lower temperature rating. This is not ideal and possibly violates code that requires high temperature rating.
Shouldn’t the green wire entering the box with the outlet have a pigtail that connects to the box itself? Meaning that the incoming ground splits to both the outlet and the box. The original setup when switched off was still grounded to source. The new configuration when unplugged is no longer grounded. This is unsafe.
The ground wire screw of the outlet should be made with a small piece of conductor that communicates with the screw that holds the outlet into to the box. Allowing the ground circut to travel into the box.
Please explain what the bonding plug is doing in the power station. The plug listed by Amazon as: " Ideal for replacement of plugs on tools, appliances and extension cords."
So sorry I had the wrong link there! My bonding plug looks exactly like that. I got that changed, thank you for letting me know. So the bonding plug just attaches the ground to neutral, so if you have a floating neutral you would need this for it to run.
@@diyhvacguy That makes sense. I had to think about why it would be a problem. Most viewers would not. Would that still work and be true if you were using a small gas generator r even car/truck inverter?
Electric furnace is probably 240 volts and the amps would be dependent on the number of heat elements. So all the plugs, outlets, and wiring would have to be sized appropriately and a generator capable of delivering 240 volt power and sufficient amperage.
Have a 13000 watts duramax generator With a 3.5 ton ac and a 2.5 ton ac both having a micro air soft start kit Do I still need this or the generator will be able to handle everything
I installed 2 wood stoves in our home...1 in the living room and 1 in the basement near all the water pipes...and I cut, split, and stack 3-4 cords of wood every year...if the power goes out, our home is warm and cozy all winter
I was thinking that during a power outage I could keep my basement somewhat warm by removing the burner element out of the gas water heater and let it run all the time to heat the air in the basement.
Just a warning for your viewers. There are battery powered thermostats that do NOT receive power from the furnace or any other source. In the case when house power is out, the thermostat will still have battery power. The problem is, in the separate case where the battery in the thermostat dies, the house will not have heat.
Right, but what are the odds of that? And it typically will say battery low on the t stat. What I really meant to say is the t stat will still CONTROL the furnace. It doesn’t need its own emergency power source. Thanks for clarifying for the viewers. Cheers
@@diyhvacguy I found your video helpful. Thanks. Not intending a conflict. Just wanted folks to know that their thermostat may be powered only by battery, not any other power source. Not related to the house power being out. Many people don't realize that their heat depends on AAA batteries. Yes, the thermostat screen will say battery out. But that doesn't help If you aren't home. For example, I used to be away more than I was home. When I bought the house it had one of those absurd battery powered thermostats. Twice my thermostat died when I was away. Both times I was saved by two different house guests who realized that the house was getting cold.
I keep a house log file and note all home maintenance items. I noted the time between getting battery low warnings on the old battery powered thermostat and just scheduled the next change on my phone calendar. The interval was 1 year if I remember correctly. Current thermostat is powered from the hvac system.

I personally prefer the version you did with the switched outlet. With this one you can just unplug it but like having the switch.
most of the repair guys will prefer a switch as well.

why argue for the 1-2 bucks extra, other than it's not code to have a 20 amp outlet on a 15 amp circuit, which is usually is on a small furnace.
@@rupe53 it’s a simple issue. The 20 amp outlet allows you to plug in a 20 amp load device. That will trip the 15 amp breaker. You shouldn’t mislead a person to think the circuit supports 20 amps when it does not.
@@neilbrookins8428 and that's the reasoning behind the code not allowing a 20 amp outlet on a 15 amp circuit. BTW, a 15 amp breaker will run overloaded for many minutes before tripping. The problem will eventually be failing insulation due to heat cycling if it gets used that way.
Good idea But why didn’t you just use one of the knockouts on the SG box instead of drilling a hole in the furnace.
Very well could have but it might get a little crowded. Changing from a single gang box to a double gang with a single outlet cover would fix that as well.
Hola señor Dave!!! Excellent video and very educational …Saludos !!!👋😊👋
Hey Very nice tutorial
Hey thank you for this video and all that you do for DIYers, just wanted to get some ideas on your approach doing this having a transformer on the opposite side of the socket
question! could one use a light switch plug combo so one doesn't lose that functionality? anyway nice video very informative and concise ^-^
Going to do this to mine at winter cleaning the furnace.i have a gas generator in garage I'm going to run an extension cord from.
Hi when you install your own diy hvac system iv seen on other video it might not be a good idea to use stay brite 8 the acid from the flux will mix with the refrigerant and cause a compressor failure unless you flush out the line sets after your done using stay brite 8.
Question, If you don't have a power station, can you use a portable gas generator outside and do you still need the bonding plug.
Thanks for such a good informational video, makes it really easy to understand.
Yes absolutely
@@diyhvacguy No, most gas generators are already bonded so no plug is needed. Also, most 120v outlets on a gas generator is gfci and you CAN’T use a bonding plug on a gfci without tripping it.
Very good video. Thanks for sharing. I've also watched your other videos about this and. Keep it up.
Great information. My question would be, can I use a car adapter plug in to run my furnace? I realize I need to keep an eye on my battery volt level.
My furnace was hard wired. It didn't have a switch. I just opened up the furnace and the junction box inside and pulled the wires to the outside of the furnace. Installed a box and outlet on the end of the house wiring. Then, I added the pigtail and the connection of the pigtail to the furnace is in the junction box inside the furnace. I just did this today in advance of this evening's big windstorm. So, I shouldn't lose power now.
I know people hate me for always pointing this out.
Anyways at 3:25. So you check the tester to see if the tester is working on a known live source, then check if what you are working on is off, BUT after seeing it is off you check the tester again to see if it did not break. It is more or less standard for how to test if something is dead. I have seen once the tester break after checking it worked then on what should of been dead and someone got shocked.
Thanks for the video. So much better than the “widow makers of the past that I had to learn to make work. But I am much older so I should know more now. Never thought of doing this method. But I gotta figure out my situation with a gas mounted furnace that’s completely outside. Hmm. I shall find a video. It’s a weird house I got and with all the outside venting ish by looks. I know how the house was originally designed in the 60s and how they decided to do the design as a single home they prob ever built with what little money they had and never meant to sold until both died. Things like design from the foundation to to the roof in 70 years amazes me.
My oil furnace has been set up like that since it was installed works great
It is verrey important , interesting , educational, GRACIAS BRO
Interesting about the furnace needing bonded neutral. Also interesting that a portable power station isn't bonded. A little info on how to tell the difference would be helpful.
Bonus: Making your own bonded plug is super easy.
most of the control circuits are DC and use the cabinet as a ground. Yeah, it's screwball but reality.
Excellent video! I have a heat pump, but only use the "emergency" gas setting. I'm confused because I only have a hot and a neutral wire supplied to the unit. Can this still be done?
Is the bonding plug necessary if the power station is plugged in an outlet? I asked because I noticed my power station has no ground stand along; but grounded when plugged in. Thanks
Great video btw!
Probably best to use a single outlet (not duplex). Any "inspector", rightfully could point out that the second outlet invites someone to wrongfully plug something in to what is required to be a single use furnace circuit. A well made, old style, twisted together wires with a well tightened and taped wire nut IS THE BEST most reliable wire connection
It's actually common to have an outlet for a condensate pump with AC or a condensing furnace. The code violation will be a 20 amp outlet on a 15 amp circuit. BTW, while a plug is ok by code as a disconnect, furnace code will still call for a switch. IOW, he probably needs both.
@@rupe53 Thank You. I have a 80% furnace and do not have any condensate pump/ condensing furnace experience. I Am of the opinion that it is too much "complicated efficiency" for stand alone reliability in these times. I too noticed the 20 amp outlet and 14 gauge cord and circuit wiring?
so a switched outlet - single or duplex as indicated?
I strongly recommend you use nothing but 3M electrical tape. It guarantees the highest quality. We use it for all connections on railroad signals in awful environments and it stays attached and remains pliable.
What kind of gas line/fitting did you use in this installation?
BTW I used your videos, got my technician license and saved $14,000 installing a hybrid 4 ton heatpump/gas furnace by myself! Thank you so much!
It’s a quick connect that is typically used for gas grills. Because this is in the middle of my garage I didn’t want to out in a permanent one so this works great. Obviously not up to code for a permanent installation.
Love the video. Thanks for the info! Heads up, Anker had a recall on a few of their powerbanks at the end of September 2024. Check out the recall notice before you purchase. I have an Anker power bank, and mine is fine.
God bless you for this good sir. Earned my sub
Thank you for your informative and easy to understand videos. I have set up y furnace as you instructed in your video. I have not tested it yet as I am trying to figure out a battery (inverter) size to buy for this purpose. I do have a Honda generator that I can plug into the lighting panel but it is larger than I would need to just run the furnace for a short period of time for emergency heat. Any suggestions on a video to recommend the best battery (inverter) brand and size to use to run the furnace in an emergency?
Inverters attached to a car usually produce "dirty power" -- NON-pure sine wave. Can this effect the sensitive control board or possibly other components????
It's better to have the switch, and have the switch run to an outlet on the wall from the start. If this is not the way it's already wired, then I guess this is a good fix, but I'd rather have a furnace switch and a wall outlet be code. Then you can simply put a UPS in, and you're good to go in emergencies. A decent UPS should be able to light a furnace for weeks of a power outage. Generators can't be indoors and require setup and possibly starting fluid to get going if they've been on ice for a while.
So what is the likelyhood the natural gas pump station will be down if the grid is down?
if you have a gas furnace, then look around it. You'll find a little box with a switch that says "auto"/"manual. When power goes, just push it to "manual," and your furnace will work, no control over the thermostat but heat in the home till power comes back. Much easier than playing with the system.
And what runs the fan ?
Outstanding job Thanks
How do you handle a fused shutoff box between your furnace and the breaker, how would you recommend wiring it in for use case?
My husband and I had someone do this for us for 50 dollars but going to a Honda generator outside, I must mention the local furnace company wanted 500 dollars for this job.
Good video! Don't see a link for the bonding plug though?
Can you run an extension cord from outside gas generator and plug it into the pigtail, instead of the battery generator?
Correct
I never thought to do this. Hey where do you get those enclosure boxes that was on the inside? I didn;t see a link for that.
Wow, thanks!
Excellent! Thanks Dave
Code in Denver says you must have a flip switch to cut power and a screw in fuse at furnace
that's actually a national code. Code also says you can't have a 20 amp outlet on a 15 amp circuit.
I have Never seen a screw in fuse at a furnace so it can not be a national rule !
@@josephpadula2283 the part about a screw in fuse likely dates back to at least WWII and never got removed. (maybe even the 1920s) The reason was adding central heat to a home without adding an extra circuit to the fuse box. IOW, tying into an existing power feed in the basement and making your own branch line. There was actually a combination switch / fuse base made to fit a 2x4 box with a small flip-up cover for the fuse. (have one in my house) Kinda cute but short lived because many just installed a ceramic bulb fixture and landed the fuse there, next to the switch box. Screw in fuses have the same thread as a lightbulb.
Nice idea man. OK if you have a "battery power station" but just with a actual generator it would have to be outside. How much power/current does the average furnace draw? If it's that 230w then the battery amp draw is 10 times that or about 20A. I know that usually the gel-cell batteries (like the ones for UPS backup) are shit. only last perhaps 2 years even if not used, and are expensive to replace.
read your data tag then figure out if the watts are combined or separate for the heater and blower. Most will be in the 200 - 400 watt range. That's 2-4 amps total. An oil or gas boiler will be in the 2-3 amp range, including the circulators.
Thank you.
Thank you. Can I do the same for a gas boiler?
Yes if it’s 120v then absolutely
@diyhvacguy Thank you!
Thanks
COOP

I only have power outage in the spring! Trees fall on the power lines.
There are all types of thermostats out there and different wires coming out of the wall from the A/C. How do you know if you are buying the right thermostat?
Hi Dave: Thanks for these "keep your furnace going" videos. Im very interested in this "Bonded Plug" fix, as Ive got a problem after having done a similar install following your previous videos. I watched and installed the “plug,switch, pigtail” setup in your 12-9-22 video as you directed, then I upgraded following your methods in the “EX Generator Switch” video of 2-24-23. I saw you used the Ecobee thermostat at your house, so I purchased and installed that too. When I tested for each setup, I confirmed functions. But, after an actual outage, and currrently using the EZ Transfer Switch setup, the furnace ran perfect off my Ecoflow Delta 2, and after a few minutes, the flame kicked off as expected based on the thermostat setting. However…the furnace fan never shuts off!! It runs on and on. So I try again. I unplug everything, let temp drop below the 70 degree setting, set furnace to 70 to call heat, the furnace kicks on again, fan comes on as usual, house warms to 70, then flame goes off as expected, and again, the fan never shuts off! The Delta 2 keeps getting drained! I reviewed that I installed to your specifications, so Im confused. Could the "Bonded Plug" be tha answer for this problem? Or would u suggest I look in another direction? Thanks.
The thermostat likely has a setting for the fan to either be on ‘auto’ (running only when heat or cooling is called for), or ‘on’ (constantly running). I helped a neighbor set up a different smart thermostat and this option was in the settings instead of being selectable from the main screen. Does your furnace fan always run while on utility power also?
@@Tvar7531 thanks for the idea, but no, the fan shuts off after the flame runs it cycle and the heating element gets cooled off. If it was always on, I wouldnt have thought something was "wrong". I wish it was that easy.
Nice vid. You know, what surprises me is that the furnace only needs 250 watts to run. And that is not much. Kinda like 3 old fashioned light bulbs worth of power.
Ya its mostly just making that big fan move but initial startup you'll need 3x that.
What generator power supply was that you are using?
You should have just installed that cable clamp in to the junction box and made the termination inside that.. Done and done. This hurts my head.
The idea is on point though.
Can you also do this if your switch is on the wall, away from the furnace? I'm trying to wrap my head around how the wiring would work. Maybe after coffee.
lol coffee is always important.
So it would be extremely easy. All you’d do is kill power at the breaker, remove your switch as well as the conduit that runs from your switch to the furnace, and then simply install the outlet where the switch was. Then you’d just put the pigtail in place of the conduit!
I could probably do a video on this but I’m not sure how many furnaces would be oriented this way.
Cheers
@@diyhvacguy Thanks, that makes sense. You mentioned something about not having the pigtail too long. The distance up the wall and over the ceiling and down to the furnace is probably longer than the 9' pigtail. Assuming I get a longer pigtail, would you be concerned about that longer length? Thanks a ton!
@@diyhvacguy I think I'm overthinking this. Couldn't I just leave the wire in the conduit, and use a short pigtail where it terminates in the switch box to then act as the plug after I change the switch to an outlet?
@@diyhvacguy It worked great! Thanks!
This is a very good video and something we want to do. The power in our city is very dependable as we have had maybe two outages in the 25 years we have lived here. However, we do need to be able to power our gas furnace in the event of an outage during the winter. Do you have any idea how much it should cost to have an electrician do this work that you showed in the video?
Probably 300-500 if I had to guess. Maybe less. The great part is it’s 100% reversible should someone say it’s “not up to code”. I’ve seen so many homes here in Utah with an outlet and a plug just like this and most inspectors would have no objections to it
What is the name of the power supply unit.?
Or where can one get something similiar ?
THANKS !
Just search portable power station, Bluetti, EcoFlow, Jackery are a few of the top brands.
Is it safe to plug this into a regular generator or will it ruin electronics inside the furnace? I have an oil fired furnace
What model of battery is that?
Can you do this with an electric furnace? I live in a mobile home and have a DOWNFLOW/UPFLOW ELECTRIC FURNACE MODELS: EB SERIES. I use a 12,500 watt generator. Can I do this with the furnace I have? Do generators need that bonded plug? With an all electric home when the power goes out I'm pretty well Boinked.
If you buy a furnace and put this receptor in, is it going to void your warranty? Plus, drilling a hole in the outside of the furnace.
What about an electric heater? And on top of that it’s a heat pump. It’s 220v isn’t it?
Great idea 💡💯💡 as Always 👍. 8 years ago when I installed a gas self igniter Heater on the Wall.... And did Convertion run on Natural gas on the GENERATOR. Everyone in my Family Complained about it and made a lot of Bad Comments. Why this and why that❓❓ 2-years Later, We we had Winter storm and ice and Power outage. Many people were moved to Hotel and some Old people were dead without electricity. Then everyone in my Family said to me " You are Smart guy and always prepared"... People in General they don't See and don't believe. In my mind I called them what a Clueless and Stupid people.
Will this work on a oil furnace?
I can see that the original furnace before modification was fed by a metal conduit and rated for high temperature. But the post modified feed is plastic with a possible lower temperature rating. This is not ideal and possibly violates code that requires high temperature rating.
Making that connection OUTSIDE the cabinet solves the code issue.
Shouldn’t the green wire entering the box with the outlet have a pigtail that connects to the box itself? Meaning that the incoming ground splits to both the outlet and the box.
The original setup when switched off was still grounded to source. The new configuration when unplugged is no longer grounded. This is unsafe.
The ground wire screw of the outlet should be made with a small piece of conductor that communicates with the screw that holds the outlet into to the box. Allowing the ground circut to travel into the box.
Please explain what the bonding plug is doing in the power station. The plug listed by Amazon as: " Ideal for replacement of plugs on tools, appliances and extension cords."
So sorry I had the wrong link there! My bonding plug looks exactly like that. I got that changed, thank you for letting me know.
So the bonding plug just attaches the ground to neutral, so if you have a floating neutral you would need this for it to run.
@@diyhvacguy That makes sense. I had to think about why it would be a problem. Most viewers would not. Would that still work and be true if you were using a small gas generator r even car/truck inverter?
I’m old world people stick to wire nuts in black gas line. Everything else is just jammed to collect the check and go.
95% of the gas furnace here use 240v, as they are packaged units. About the only ones I ever see 120v are in mobile homes.
Link to bonding plug?
In video description 👍🏼
@@diyhvacguy @TC-tw5zk Now I see the link. I had to refresh the video page. THANKS!
Why are you putting a 20 amp outlet on a 14 gauge wire? You need to replace that with a 15 amp.
Does using the bonding plug apply to when you use a gas generator too?
Depends on the generator but a lot of times yes
@diyhvacguy thankyou
How about a oil burner?
same idea.
How many watts is everyone seeing being used by your furnace? I’m trying to see how long the power station lasts.
Where do you get the bonding plug????
A much better and legal way would be to have a 3 position toggle switch, on, off, on, with a power inlet.
Im totally lost on what the binding plug does or for.
Seems it shoukd work fine if its getting power.
And my power bank only has 1 outlet
This is a very good video!
If I do this with a battery/inverter, will I run into the ground/neutral bonding issue? Does the furnace test that the ground is bonded somehow?
Would plugging the bonding plug into the new outlet work as well? I assume so.
Does this work for an electric furnace?
Electric furnace is probably 240 volts and the amps would be dependent on the number of heat elements. So all the plugs, outlets, and wiring would have to be sized appropriately and a generator capable of delivering 240 volt power and sufficient amperage.
Have a 13000 watts duramax generator
With a 3.5 ton ac and a 2.5 ton ac both having a micro air soft start kit
Do I still need this or the generator will be able to handle everything
Hi you wouldn't need to buy this from amazon home depot sales these unless people want to spend extra money on shipping.
I installed 2 wood stoves in our home...1 in the living room and 1 in the basement near all the water pipes...and I cut, split, and stack 3-4 cords of wood every year...if the power goes out, our home is warm and cozy all winter
I was thinking that during a power outage I could keep my basement somewhat warm by removing the burner element out of the gas water heater and let it run all the time to heat the air in the basement.
Just a warning for your viewers. There are battery powered thermostats that do NOT receive power from the furnace or any other source. In the case when house power is out, the thermostat will still have battery power. The problem is, in the separate case where the battery in the thermostat dies, the house will not have heat.
Right, but what are the odds of that? And it typically will say battery low on the t stat.
What I really meant to say is the t stat will still CONTROL the furnace. It doesn’t need its own emergency power source. Thanks for clarifying for the viewers.
Cheers
@@diyhvacguy I found your video helpful. Thanks. Not intending a conflict.
Just wanted folks to know that their thermostat may be powered only by battery, not any other power source. Not related to the house power being out.
Many people don't realize that their heat depends on AAA batteries.
Yes, the thermostat screen will say battery out. But that doesn't help If you aren't home. For example, I used to be away more than I was home. When I bought the house it had one of those absurd battery powered thermostats. Twice my thermostat died when I was away. Both times I was saved by two different house guests who realized that the house was getting cold.
I keep a house log file and note all home maintenance items. I noted the time between getting battery low warnings on the old battery powered thermostat and just scheduled the next change on my phone calendar. The interval was 1 year if I remember correctly. Current thermostat is powered from the hvac system.
Don't see that working on my electric furnace. So many code violations on this setup.
You ant kidding. This is so wrong they might even put you in jail.
