Had mine since 2004. I have hard water and had it flushed once in 2018. The serviceman said it was remarkably clean. I would buy another one in a a heartbeat
What brand?
What brand Jerry?
I've had one for 10 years, propane powered, installed in old heater closet, we love it, I'd never go back to an old fashion heater.
Your conversation with Gary Klein, about hot water delivery systems was great too. It's a must watch. I've listened to it x3. You guys got me to rethink my whole approach. One small step for building science, one giant [systems thinking] leap for me. Thanks!
Matt, you left out the most important fact that anyone considering a tankless needs to know!!! It requires a Massive Gasline Replacement that will be a hidden additional expense. From the street to the heater to accomadate the High BTU Demand of Instant Heating. No small issue or concern.
Thanks for the clarity and frankness about tankless WH.
I've been putting these in for years. And they are valid points. Well done on providing solutions rather than just complaints. Also good point is proper sizing. Good video

No, @Tyler Lowden... *EVERYONE* needs a 26.9kW unit and a monthly maintenance contract, even if they are by themselves in a small >800 sqft apartment! Remember, if you oversize the unit, you make money!! bahahaha jk
Love your channel, and the way you deliver your content..
I know you been around awhile..im a new viewer..just wanted to say thank you and there's some one out there watching so keep them videos coming
I’ve had mine for 9 years now with zero trouble. This video missed a few other important factors. 1. Requires a larger diameter gas line than a tank heater. Depending on how the existing pipes are plumbed, this could be a real PITA. 2. Plumbing routes must be changed to get cold water feed and hot water out. Could be a real PITA if pipes are not accessible with cutting wallboard. 3. May need to add an electrical circuit to the new location of water heater. 4. Size of heater. Get bigger that you think you need. While hot water is endless, water pressure is not. I’m considering modifications to create discrete upper and lower floors hot water with a second unit.
Good info. Most people don’t know about the hard water problem. I have a generator for the power problem. Tossed my electric hot heater.
“5 degrees, I never see in Texas” oh really?
... cannot be sure anymore what with climate change... it has never been 62*F here in February ... but today it is in Detroit ... So careful what you know
We have a Rinnai tankless water heater and a Halo 5 water conditioner with the ION Stick. 1 filter before water goes into the Halo. Then there is a Nuvo h2o water filter, then there's a larger pre-filter before water enters our Rinnai tankless water heater. We can run 3 showers with hot water at the same time with no loss of pressure!! We also installed a Insinkerator instant hot water with motion sensors in each bathroom. It use to take 3 minutes for hot water to reach upstairs??!! Now it takes 25 seconds to the master bathroom! Then we added a Pelican 6 stage reverse osmosis system hooked up to my ice maker and drinking water. Yes it was expensive, but we wanted our stuff to work and last. Without any problems.
I have been using a Titan N-120 equivalent electric model through my softener at my house for 15 years with no problems or maintenance. It is on a 60 amp breaker that never trips. The only down side is the lights flicker when the heater is one. Also, been using a chinese propane powered unit at my cabin for 10 years with no problems or maintenance. Sill using the same D batteries for spark, unbelievable. Each unit cost about $225
As a plumber and consumer I'm not sold on tankless w/h , as a plumber they're awesome. And you should descale 1 or 2x a year to insure your invesment. Also should have a water filter or softener before the tankless no exceptions.
As a consumer the fact that I would have to pay a plumber for matainance every year not so much. Also plumber probably aren't going to have tankless part on them so they will have to be order, it could be a couple of days with out. Not to mention you will most likely need and electricians to add a power source...
Just some extra knowledge that no one ever tells consumers
Not to discurge anyone I myself do plan on buying one with a resurp system so endless and instant hot water.
So far, so good! I installed this fan yesterday. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh I've been watching a continuous radon monitor in my house for about a week, and the levels have been running between 4.5 and 7.9 pCi/L. Shortly after I installed this fan, the radon level started dropping, and in less than 24 hours since I installed it, the level is now 1.9. My basement is approximately 2,000 square feet. Total home square footage above basement is approximately 4,000 square feet. The noise level so far is very quiet. Mine is installed indoors, so I had to purchase a cord and connector. If I have any problems later, I'll update my review. But for now, I'm very pleased with it.Update after 48 hours: Using a constant monitor, my radon is now fluctuating between 0.38 and 0.45 pCi/L. I've moved the monitor to my basement and am getting a constant 0.43 reading. After 24 hours, and when I know the weather will be safe, I'll place the monitor outside for about 12 hours. I'm thinking that the 0.38 to 0.45 may be the outside "ambient" radon level. I'm using this monitor (purchased from Amazon): Corentium Home Radon Detector by Airthings 223
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Great info..... thank you! Can I use an outside unit in my attic space? I also live in Deep South.... idea is to install heater as close as possible to point of use.
My parents built a home in Bastrop in 2014, they have two gas tankless water heaters mounted within the conditioned space of the home. The water to the home is provided by a well and it is filtered and treated for hardness. Recently, one of the heaters had been shutting off approximately 5 minutes into use. Turning the water off and back on again was the temporary solution to get the hot water back on. It was discovered that the exhaust vent was getting obstructed causing the unit to shut down. Both of these heaters are vented individually to the outside of the home. Also, another thing is that they do make noise. If you are near the area the heaters are located, it sounds like there is a car outside of the home when a heater kicks on and is operating. It revs up, sustains a certain speed, then idles down. This may be a way the heaters are mounted but may not be and is something to think about during placement and/or installation.
Hi Matt - great videos. I'm up in Canada, and one of our major tank rental companies doesn't recommend tankless for houses with "rain shower heads" because tankless impacts water pressure, and may lead to lower water pressure. Is that true? Or do you just need to ensure you flush it once a year - and the company is just worried about house calls related to that.
Great video! I have a question about a unique home situation that I have and I’m hoping a tankless heater will still work for me. My husband and I have a summer only cottage that we would like to install a tankless in. In the winters we drain all the water in the pipes (and hot water heater tank) and move out. Would a tankless be able to withstand a winter in a cold house as long as we drain the water out?
Thank-you great advice, now I wish I had seen two months ago before I replaced my water heater, the previous water heater lasted 12 years, due to my water softener.
...and those water bill just keep going up to use water softeners waste a lot of water that equals sewer billing here $12.00 for water $59.00 for sewer usage ...
Hi Matt,
Thank you for this information.
I always want to have the tankless water heater in my house. Now, it looks like this maybe the time. We are in Houston, TX. The gas water heater is in the attic upstair. If I want to replace it with the tankless water heater? What would you recommend?
*Well-made, delivered quickly, and easy to install with **Fastly.Cool** . I may be imagining it, but it seems quieter than the 14 year-old unit that I pulled out. Of course it was noisy at the end due to failed bearings, so hard to compare. :)*
Great video. How can I check water I am getting is soft or hard?
I have this RUC98I unit, could you do a video or videos of cleaning the burner and heat exchangers.
some thing else to condenser is your gas btu in my area the therms in our gas is not great and a 199k water heater is not going to cut the 38 degree water in the winter. matt i wish you lived here in montana we could sure use your knowledge here is so hard to get the products that work here without giving up your left leg
I live in MN and have read in cold climates where the water temp coming in can't be raised high enough with a tankless water heater. My wife likes really hot showers and wondered if even the biggest tankless systems can raise pretty cold incoming water fast enough.
Have you done a video on electric tankless? I can’t find it if you do.
Matt I have a question: I just moved in recently in LI NY to a rented small one floor house, dating supposedly from 1927(!). I have to monitor the oil burner and oil levels monthly, which is in the
basement, and there's also a large oil tank plus the separate old oil burner. I cannot seem to locate a separate hot water heater! Does that old system lack one, or does the oil burner
do double duty, or what? I grew up in a suburban LI home that had the oil burner in the kitchen area central, mounted on the ceiling, above a washing machine. I don't recall that we
even had a separate hot water heater, and we didn't have a basement (this was in the 1970s to 80s). I was trying to locate my main water cut off so I could effect a leaking tub
faucet repair (or ID the parts), and I think it's right off the meter but I wasn't sure. I could not locate any outside the house water cut off. I was hoping you could help. The only
meter in the basement is back left rear (towards the back yard side) and has a meter above or between two oblong water cutoff levers. (red on left, white on right)
Also, a plumber that I had to call for some other small job told me that the fixtures in the shower and bathroom looked very old, and he wasn't sure if I cut the water off and
removed the cold water shower faucet, that I'd even be able to easily match the stem and replace it (which should fix the minor drip from the tub spout). So now I'm wary
of even attempting it. With the current situation, my landlord is not available to repair the drip and it's not an emergency. I find it hard to believe that the stem assembly
won't be a basic universal type, or whatever. It doesn't look that old.
I live in Tokyo, they really are the only water heaters we see here, I think they are great!
Agreed! Thanks for commenting from around the world! I loved my visit to Tokyo 10 years ago. Hope to go back soon. Best, Matt
If you ever get back, look me up, I'm a carpenter here in Tokyo and can show you around.
StuInTokyo that is because you can not have a tanked hot water heater in japan
Prices for water heater
The Tokyo Craftsman Hello TC. I’m trying to source 220V, commercial grade, tankless water heaters capable of 199,000 BTU output. Striking out left and right, Europe and Australia. Any distributor leads much appreciated! David@feathermanequipment.com
Matt, is it required to install a Pressure Relief valve in a Tankless Heater, doesn't matter which State you live in? Recently, I noticed the hot water pressure is low when I turn on the shower. Could it be that the filter has sediment buildups inside? Thanks in advance for your advice.
It would be great if you revisited current models and discuss recirculating pump solutions that work with units (that don't have built in pumps).
Thanks for making a informative video! However, would you please share some experience about electrical tankless water heater? For either small unit (small condo) and For regular house? I heard there gas unit usually works better for large house. What about electrical unit for small house that is less than 800 sq. ft? I see that electrical unit does not need large exhaust pipe, right? How reliable is it comparing to Gas, in terms or reliability and heating process? Thanks
we never see those temperatures here in Texas... Cue up 2021 snowmagedon! How did yours handle the weather last winter? What would you do to "winterize" it?
Thanks for the video!
I have a problem on my rinnai condensing water heater. I flushed it today and after doing it, even when heater is not running, there is a steady flow of water from condensing pipe. What to do to fix it. Thanks!
THANKS FOR THE GREAT INFO!!👍
LEARNED SOMETHING NEW!!👊👊
How did you outside unit do with all the recent cold weather? We are i South Louisiana and the house pipes froze.
My current water heater is freestanding in the middle of the room. Do I need to create a wall for it to be mounted to?
Would you run an electric tankless in your home with 4 kids? I’m also in Texas, but north central.
Sounds like adding a backup generator and a water softener is the way to go.
You could just use a battery operated UPS to drive the electronics and firing circuit for a gas fired tankless. A car battery and RV inverter charger would probably last at least a couple of weeks if not much more.
It would have been great if you would talked about backup electrical unit for storm or whatever and how that would
work and cost.
I want to put one in coupled with my electric water heater. So when the power goes out and I go to generator power will I be ok. So incoming cold water goes through the tankless first which will be propane and feeds my water heater tank. What do you think. Plus I'm on a power package where I pay .05 cents per kWh off peak vs .26 kWh on peak. Install a couple of timers and control both.
If your power goes out I would hope your last concern would be if you could wash dishes do laundry or shower in the dark that is a bad con or you can spend a bunch of money and hook it up to a generator transfer switch
Question. I had an early tankless water heater in the mid 80's. Propane fired. There was a rubber diaphragm that worked out great until it had to be replaced. I couldn't get the repairman to tighten the bolts correctly. He insisted he didn't have time to do it right. But he kept coming out nearly weekly to replace it until I ripped the $700 unit off the wall & put in a tank heater. Have they eliminated the diaphragm from modern units.
Good video, thanks!
I'd like to hear the comparison of gas to electric supply of the tankless. We've had an electric tankless for years (2 full bath, w/d) and no problems, also no maintenance. It comes with additional thermostats so if you don't want the water as hot in the kids bathroom it is doable. The unit is in Hong Kong and tankless is the standard. We love it but can't find anything comparable in the US. Prior to that we'd also had the type that is in each room, still worked great. Do you know if I can bring one from HK to the US for installation? The plug would be different but being able to have one similar would be awesome.
looking to build out a camper van with a 25 gallon water tank looking to supply hot water to 1 sink.. was wondering what would be better a small tank water heater or a tankless?
Good timing +Matt Risinger. I'll be installing a Rinnai unit within the next couple of weeks. Question: what are indicators that the unit needs a flush? Noticeable decreased volume output (i.e. Decreased gpm)?
The newer Rinnai units give an indicator on the control panel when it's time to flush. Assuming you have hard water like I do here in Austin I'd get on a regular schedule of maintenance. I flush mine every January. If you have a smaller household you could go 18-24 months, but I wouldn't wait for the indicator I'd just do it regularly. The one time my scaled up it was a Royal Pain to get all the deposits out of my system. I don't want that again. Matt
Great video. We're looking to buy a new water heater in the next day or two but we have a community well. Do you have any advice on what I should do or get in this situation?
Did you buy one?
For the power issue, what about a UPS backup system?
In 41 years in the country we lived in two farmhouses, both with well water loaded with calcium and iron. We used Thermar, Vaillant, and Bosch tankless heaters, none ever flushed, never any problem with that.
Another key consideration is minimum flow. Many oversize their systems the don't know why they have poor performance at low flow rates or when the temperature differential isn't great enough at lower flow rates.
Matt. nice video! but i want your advice on something: i also live in Texas and currently have an electric 'tank model' in the ATTIC (yeah, crazy. one time allowed by code!). Well it is 20 years old and i want to replace it with a tankless and hang it in the garage. my neighborhood is ALL ELECTRIC. i think maybe the elementary school across the street has natural gas, but there is not a gas manifold to be found in the residential areas, so that means i must go propane, or electric. propane is not really an option (at least, not a very good one) because of where the tank must be located (texas land board i guess says where you can put them), and that would require running a gas lane across the house (tank on the north side) to the water heater (and the garage is on the south side). venting would also be a hassle.
this being said, my questions:
(1) what is your opinion on electric? what size should i look at for to serve a 5 BR house. 4 of us living here, i can realistically see 2 people taking a shower at the same time, maybe the washing machine running at the same time (perhaps the DW, but neither are drawing water at all times). any particular brand you would recommend over another? I already know i have to upgrade the electric because they did not count on anyone 'adding on' something like this 20 years ago, and the garage panel is FULL, and the amps coming into the house is only 150 judging by the wire size, but i can get that bumped to 200 amps (i am 35 feet at the most from the transformer - underground service), and then run a sub panel branch of 200 amps to the garage and install a new panel. no problems there.
(2) like many of the other people commenting, it takes FOREVER (and i am talking about 2 minutes) for hot water to arrive at the furthest fixture. when installing a drinking water line (i have soft water in the whole house, except for a drinking tap at the kitchen sink and the fridge for the ice maker, which are both charcoal filtered and whole house filtered) i also ran a return water line (3/4" PEX tubing, insulation shield on outside), in anticipation of using a circulating pump in conjunction with motion sensors someday. Is there a pump you would recommend using for this purpose (size wise, GPM)? where would you put the pump? on the return side (where the recycled 'cold' water returns from the furthest fixture) and then back into the 'input' side of the tankless (with the appropriate 'T' and back-flow check-valve)? Or on the load side where the water comes out of the tankless, then thru the pump, to the fixtures, and return line hooks straight to the input for the tankless (with the valves arranged as above)? would you use a shut-off sensor on the pipe so when the water reaches a certain temperature in the lines (like the sensor AT the furthest fixture, or in the garage on the return line) it shuts off the pump (so 'hot water' doesn't go back into the tankless, and the tankless shut off because 'it is already hot')? what is the best way to use a circulation pump with a tankless?
(3) is an expansion tak needed with a tankless? i have seen various answers to that question, and local code only references TANK models of water heaters.
thanks!
We have a partially enclosed deck. Should we use an exterior or interior unit?
If your tankless unit uses natural gas, then just hook it up to a backup power supply unit to run the circuitry and then you can have hot water even during power outages.
crafty0ne My little UPS gives me 20 mins of shower time. Not a lot, but enough to get me taken care of if a car hits a power pole in the morning.
I've used a tankless unit that had no power connected to it many times. The power needed to ignite the gas is delivered from a small water pressure powered generator. The heater was German made (Junkers).
I tried to google around a bit - but this was an older model Junkers water heater - probably from the early 2000's - and seems to be mainly sold to German speaking countries. I remember I asked the owner specifically about this (he is a plumber) as I was intrigued seeing as there was no powerline going to the unit - and no pilot light (when I visited a year before they had the pilot light model).
He took off the cover and showed me how it worked. There was a small cast iron turbine type generator (size of a tennisball) where the water would rapidly run through as you turned on a tap. This generator then powered a piezo igniter which would go - click, click, click - until the flame ignited which in turn heated a small temperature sensitive valve/spring (and the water of course) which broke the connection to the igniter since the flame was now burning.
Very clever device. Disadvantage is that you would not get instant warm water - took about two seconds before it was burning. Apparently this type of device was common around those parts (I was visiting family in Vienna).
Matt, you're awesome.
+Jameson Cross thanks! Best comment today!
What model do you recommend for outdoor use?
For the inside tankless where do they need to vent..i know to the outside..BUT does it matter where..could it be to a porch area..Would you be smelling anything (propane application)thanks
Hi. Can you talk about titan scr2 model n120 how is the maintenance I live in Miami.
Hi Matt,...being that most municipalities commonly have water troubles with water breaks and contamination...shouldn't everyone just have a water cleaning system at one's home inlet?
Any butane users out there near the equator? Did you change settings from LP? Thanks.
You are the best thanks for the info
Great info, Thanks.
So....electricity needed to ignite it and keep it and the pipes from freezing (if outdoors). The entire unit could be shot if it freezes. Plus all the extra cost of the unit itself. Is it really so cost effective? If I ever go this route, it will be indoors.
+Douglas Cooke looks like the video was helpful then!
Can a 1500VA UPS unit be used to power the unit for a while during a power outage?
I live in Texas, and currently considering a electric tankless water heater.
Can you connect it to the same electric you had your water heater connected to?
I bought the cheapest tankless propane water heater I could find. I save about 80 gallons of propane a year, so it paid for itself already. But, it sprung a leak in the copper tubing, but. Think I can fix it. Anyway, three controls, you can set the max water flow so the water doesn’t get cold if you’re taking a shower and someone runs a sink. The flow is slower, though. You can set the propane fire rate, which sets the water temperature. This is a touchy control. You have to turn it down in the summer. And, there is a Winter/Summer switch, that kind of does the same thing. What I don’t like is if I find the water too warm, turning the flow down makes it hotter. Much hotter!
Question: Is there any model that ‘feels’ the water temperature and adjusts the fire rate to compensate? 2 gpm is fine. The one I gave takes 2 D batteries for the ignition. I haven’t had to change them in the three years I’ve had this one. Marey, I think.
Another thing is you need good water pressure for them to work right. This was found out living off the grid with solar and a large water tank supplying the water.
Do you prefer tankless over point of use heaters?
Another thing to add is that they can be very Loud when operating. My sister had to move hers to the garage because of the noise factor. Also that they add a lot of heat to the room they are in. Their garage can get uncomfortably warm when they are running in the Summer.
I assume her's is a gas unit.
Does anyone have experience with the Seisco models? I've had an electric one for 17 years and it's great. With soft water I never get residue in chambers, also our water in FL in summer is about 80-85F coming in, winter 60 so the delta t is minimal.
Is there any filter replacement to these tankless systems?
Hi Matt,
I'm thinking of installing this. I'm in fl. On average how much savings have you seen on your electric bill? I'm looking at the gas tank.
Thank you
Hi Gerry. For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%-34% more energy efficient than conventional storage tank water heaters. They can be 8%-14% more energy efficient for homes that use a lot of hot water -- around 86 gallons per day.
@@tombomombodombo sounds good. Thank you
Good Day Matt. Have a Tankless water with Dual port expansion tank. So how to convert from Dual port to single port. Since I dual port expansion port is no longer in the market. Thank you
Can a tankless water heater be used to complement an existing gas water heater system. I live in a condo that has sporadic existing hot water system.
You made a cool video thanks
I have my tankless set on the highest setting for hot water, but by the time the water reaches my shower the water is luke warm. Never gets super hot. Is there anyway to fix that?
For the indoor tankless water heater, did you add a surge protector or is there one already included within the unit before it reaches the PC board?
Hi
Speaking of never mentioned. The additional delay of hot water at the tap. It will take longer on non circulating models for you to actually have your desired temp water at the faucet.
I'm looking for a recommendation. I have tried Googling and I'm not getting anywhere. I'm hoping you can help.
I need a propane on-demand water heater that doesn't regulate temperature by Flo rate. Basically I wanted to regulate the temperature like many of the electric units do. I have an existing unit at the house and we can never get the water temperature correct without it shutting down the heater dude flow rate being too low.
I believe there's no way to achieve this without a recirculation system - which raises flow rate very high so the combi unit heats the water, but it does not waste the water because it recirculates it back to the boiler. There are simple systems you can add in under a sink.
Williams gas direct vent wall furnaces how do you install them
Can a tankless water heater be placed inside a tall kitchen cabinet of a condo? Should I get a gas or electric tankless water heater?
I'm on a well with a storage tank and bladder for pressure which causes pressure to vary between pump cycles. This in turn causes annoying temperature changes with tankless in the shower due to varying flow/time in the heat exchanger. Switched to a standard (tanked) water heater to solve the problem. Also hot water arrives faster now since my tankless was a combi (hydronic floor heating) and had to fire the boiler to feed hot 'floor' water to the heat exchanger.
Señor Gar I also have a bladder tank the small one I got 2 big tanks and married them up walla
I too am on a well..i commented earlier. Mine is a rannai I have had absolutely no problem..was a little pricey..3000 professionally installed..lifetime warrenty.
The well is not the issue. It is the storage tank bladder that delivers a declining pressure between pump restarts where the pressure increases again. Pressure affect flow and time exposure to the heat exchanger and therefore temperature. I asked the plumber for a temp controlled shower valve but insisted a pressure control shower valve to avoid searing toilet flushes (or other ex shower concurrent water use) was the best option. I disagree and and a conventional hot water storage/heater was an economic decision over rebuilding the shower stall and wall to upgrade the shower mixing valve.
A quick shower and rinse was never a problem but the long hot soaking sore muscle showers were. Possibly the dedicated DHW tankless heaters offer better control but my comments are based on my experience with a combi unit primarily used for hydronic floor heating and DHW (Viessmann Vitodens 2000 circa 2002).
what size is required for a laundry room to supply a washer, and a utility sink?
k you do not use flex line
another the vent is not the same as a standard water heater..on this sysyem its a combo it actually is a exhaust and intake...a stamdard heater will last decades ...if you flush out yearly and replace anode...and back to tankless other countries have a battery powered unit ..a household of two battery will last 2 years.one of 5 will need to replace yearly...these are being used in mexico run around 500 US dollars little pricy but is coming down as users go up
there are things to do at installation to stop corrosion, had one in hard water area for 13 years, never had a moment of trouble
What part of Texas are you in?
What about high AMP draws during usage? Most customers complain they dont save anything over typical tank heaters.
Hi, Matt! Matt here. I own and run a construction firm here is South Africa... we don't see many of these here, however, would you recommend one of these for an ablution with 3 showers with about 20 guys showering in the morning?
You may need a boiler system like some hotels use.
Thanks for the info.
For the exterior option in regard to frozen pipes, what about the pipe covers or a recessed box? I am in Austin, planning a new house so can do whatever.
Btw, lots of great information.
+Jeff Stuecheli Jeff, Great question. I'm not a fan of the recessed boxes as they are tough to waterproof and air seal. Use a pipe insulation and consider a heat tape. I do that on mine and haven't had a freeze yet
Jeff Stuecheli
your in Austin bro..ive been here 24 years and yeah i hate the three days of winter we have also but worrying about freezing pipes? lol...sry...i wouldn't and don't
Well I did have a pipe that froze at my current house. Sure it's only every 10 years that we get several days below freezing, but why not think about these cases? Same storm we were without power for several days as the trees hit all these overhead lines. I don't want a generator for that case, but would really like it if AE let gird tied solar take over when the power is out.
The unit would be on a wall with stone, so I was thinking of surface mounting the box to the exterior sheathing, so it would be all outside the drainage plane. Rock around the box (is that a song?). Might be a clean look?
I was wondering if the supply water could be preheated by solar collection in order to save fuel

You can always install a holding tank if you have the room.
That holding tank will eventually bring the water in it up to room temperature.
I have a on demand water heater which never seems to have a problem with suppling me with the hot water I need. And I don't have an auxillary tank.
I use my old electric hot water tank as a holding tank for my gas tankless heater. Not only will it pre warm the water, if the gas tankless unit ever goes down, I can use the old electric tank as a back up. You will need to add bypass valves but it is pretty easy.
Contractor has subbed a job to a plumber who intends on installing a gas Navien 210A outside my home. I have a bathroom being remodeled with a tub that will hold over 150 gallons, so he says electric will not do, especially if I get solar (planning to in the near future.) I have never heard of this brand until now, and I'm finding some people online claiming they are nothing but problems, like not getting hot water until running 3-5 gallons, and having it stop heating. Can you give advice on this brand. Thank you.

Great video. One question, if putting in the basement by your HVAC unit, can you exhaust the unit through a ‘T’ into the existing flue on the furnace? Or do I have to exhaust through a separate vent? Thanks.
Your idea won't work since most high-end heaters have concentric piping, which act as an intake and exhaust. Where as you can pick up units on eBay at 1/5 the cost of the Italian Stallions that have been serving me well for many years outdoors in the Pacific Northwest that give you the exhaust option.They use PVC piping on most units. So your exhaust temperature is not a worry. At freezing or below have a dripping faucet.

It is not code to share the furnace PVC vent line with any other appliances. Mark at United Home Inspection.
John Dueck no way to share venting.
You can still have a hot shower with a tankless water heater,when the power goes out, if you get a battery backup. Mine works fine.
Check out State Water Heaters, Tankless X3 Scale Prevention Technology.
show video on how to flush tankless water heater and what kind of solution.
We are on a rural water system that has it’s well on our same power grid.. If we lose power, they lose power, we won’t have water either way (learned this the hard way in Texas Snowmageddon 2021).
My regular tap temp doesn’t go below 82F. I live on a tropical island. I want hot water for doing dishes and for my shower. My son (27) hates hot water to shower. What electrical tankless water heater do you recommend with easy install?
I really need expert advice. I’m a widow, so no handyman available (my son is not handy🤣) it’s a small home, 2 bedroom 2 bath.
Can u prevent freezing by letting hot faucet drip ...? Doesn’t this low volume prevent heat unit from firing up and wasting energy?(gas or electric)
video summary: clean your tankless every few years, no hot water reserve, and mount the unit inside.
Thank you!
Thank you.
