Install a Mini Water Heater DIY (
HTML-код
- Опубликовано: 7 окт 2013
- Did you ever turn on the hot water heater in the kitchen sink and it runs lukewarm for about 30 seconds? It's because the water heater is located on the other side of the house. Studies show there's about two and a half gallons of water in the line that has to be pushed out before you ever get hot water. And that is a big waste. But by installing an under the sink hot water heater, you can save water and still get hot water on demand.

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).
Mr. H - That was outstanding! Somebody needs to put you on the DIY channel. You have a way of explaining things very thoroughly. Thanks!
Thank you!
Thank you very informative
This was a great video👍 Thank you for all the detailed information..It will make my project a lot easier..best of luck
Thanks!
Good job i understood everything
can I use that just for my shower?
What's the brand of the mini water heater and how does it produce heat? Where can we purchase it from?
What is more economical on electricity? A tankless, instantaneous heater or a heater with a tank? How many KW is both options?
What about the temperature/pressure relief blow off valve? I didn't see you address that issue.
What about the overflow valve?
i would love to connect it directly to shower i have a tank yet i have to rush because water gets cold fast
My primary concern is the flood that will inevitably happen when the tank eventually leaks. Probably right after the 4 or 6 year warranty period. No catch pan or drain. I would want a way to have a catch pan with drain to the outside......BTW.....This video was from Michael Holigan's "Your New House" which aired until 2007. "Super Handyman" Al Carrell aka Albert Raymond Carrell (September 2, 1925 - August 27, 2014) was an American author, columnist, TV and radio personality. He was a popular home construction/improvement expert. Carrell's column ran in over 250 newspapers in the U.S. RIP, Mr. Carrell.
Only 6 days before his 79th birthday. That kinda sucks :(
I used an old baking sheet and placed a Leak Alert water detector in it. Avoided a catastrophic leak when heater sprung a leak.
You never said to purge the air out of the tank or the lines before plugging in to power source.
sir I have a question I live in Dominican Republic and here there is only one line cold water can I use this
Where we can buy ?
A critical step that is missing is letting the water heater fill up with water before plugging it in. You would need to open the hot water faucet and let all of the air come out before powering on the unit.
Not necessary. Do your homework before you spout out misinformed comments. This unit has a cutoff that triggers if there is no water, so no matter when you fill it the electrical will NOT start trying to heat water if there is none.
@@AztecWarrior69 no need to get your feathers ruffled.
@@braznartn5176 Yes the ole strawman comment. Make some stupid non evidenced based comment so that you feel you are in the right or win an argument.
In this case you want to brand me emotional so that you feel/want/think it will discredit me personally. This is done so that you yourself won't (hoping you don't have to) have to make an intelligent rebuttal or argument.
You poor cupcake. Take your time and reflect on your over emotional, life. Must be hard going through it when everything gets under your thin skin.
How can you get cold water from hot water valve? I saw you connected tank inlet from hot water shutoff valve.
how do u know sizes of fittings???
Is it OK to not route the TPR valve through a pipe to an overflow bucket or to the outside?
No, it's a code violation to leave it like that.
where is a link to where to buy the water heater???
You didn't show how to route the discharge from the pressure relief valve or any information about electrical requirements.
“So we can stop wasting water” proceeds to stare at running sink
Infa red water heaters are working really well and never get calcium build up. With such low maintenance why are they not swamping the market? I want one and no plumbers or pluming supply in my are has ever heard of them.
One thing that is never addressed is electricity and current draw of these little heaters. A typical small unit is usually rated around 1500 watts which is around 13 Amps. In this video it looks like he plugged in the water heater in the same outlet that the garbage disposal is connected to which also pulls anywhere from 3-10 Amps. So it would seem if you turn the garbage disposal on when the water heater is active, you'll blow the breaker (assuming a 20amp breaker).
So my question is, does this blow the breaker?
Al Carrell passed away in 2014.
I agree you could not run the dishwasher at the same time as the water heater, most likely on the same circuit. as it would be too much for a 20 amp breaker.
And the spin that this saves water but neglect how much it’s wasting electricity.
@@samdeir it's saving electricity (or gas) as well. If you want hot water from your big heater you have to run the water for 30 seconds (or 2.5 gallons) of cold water before you get any hot water. What that means is you are wasting whatever amount of energy it takes to heat up 2.5 gallons. The saving in energy may actually be more than that of water.
bath tub?
Did you hook up the heater inlet on the tank to the hot water valve?
Looks like you connected the inlet back to the hot water
Yes, because in this instance you're heating up your hot water line where it sits in the pipe and gets cold.
Great video, question my titan hot water was already installed and it doesn't just plug in to an outlet it's hard wired in a junction box. Right now it doesn't have water to it. Its making an awful buzzing noise. I thought if I disconnected all power it would stop, but it hasn't. The juntion box has a white wire on the top and bottom of the juntion box. Its not the electrical in put or out put. I've disconnected all electrical wires capped and taped the wire nuts on. It's still buzzing, it's the two white wires, do I just pull them out.?
I took a picture but attached it
I had great water pressure before installing my mini heater. Now I just have a trickle. Can you give me any ideas to check? TY!
Was it a new water heater?
The T connector with the inserts....where did you purchase these items.
Went to a national hardware store retailer....this part is not available.
Where did you purchase the T Connector and two inserts?
You did not install Discharge Pipe. Is it optional on this brand of mini water heater ?
these are the future ... central massive waters tanks are really stupid if you think about them ... localizing energy in general, is the way forward... much more efficient and simple really.
I have a high efficiency Honeywell water heater that has no pilot light. The cost of it's operation is next to nothing, and I don't have multiple heating units taking up space at every sink and bath. Not to mention I didn't have to run gas or 240V power anywhere, as you would with tankless designs.
so why did you use the cold water inlet and not the hot water for the inlet to the under the sink unit so when the hot water from the main water heater gets to that under the sink heater it then turns off that heater to save some electricity.
He did you’re just not paying attention
There are many videos on POU heaters but they all draw from the COLD water source. I have a very capable whole house tankless. The problem is that it takes 1.5 minutes to get hot water to the sink/dishwasher. Is there unit that draws from the HOT water source which would instantly deliver hot water for 1.5 minutes or until the whole house system kicks in. If not, what happens if you install a tankless POU unit to the HOT water supply?
He just showed connecting that one to the hot water.
@@stevedawson4781 Thanks. I bought and installed one and it works great
I appreciate that you made this video but shouldn't the electrical outlet be GCFI?
Never showed how the thermostat worked and where the best setting is. I have one and can’t find an owner manual or anything that shows the thermostat settings.
It's on the side on the front and white part of the unit. It's a dial like with the old transistor radios. Just start out cold and turn it up till it's hot enough.
Brad Weaver or google the manual.
@@craigcooper8593 thank you!
should have run some water through tank before plugging in!!!
Can it be used for shower?
Yes, but it still relies off having a hot water feed on the inlet to this heater. One very important point missing from this video is that this heater is only designed to give you about two gallons of hot water, which should be just enough flow for the hot water from your regular water heater to reach you.
ok so what unit is it u never said
Yes, what model is this?
List of fitting sizes would be nice.
Agreed. However, with the Bosch units, there are different sizes for different models, AND the manuals from Bosch are wrong. I grabbed my digital calipers and measured. Heading to the home store now.
is this an insta hot tank
No. these do not get that hot.
You really need to explain that the TPR needs to be piped outside of the house. The video is incomplete and dangerous. Please read all installation instructions before hooking up this heater.
I ran my TPR to the drain. I don't think that it needs to go outside of the house.
Hey 👋 I just got a mini tankless water heater off of Facebook market place and I didn't think to get an owners manual. Do you have any suggestions on how to get one?
@@sherricabinaw3035 Google it.
It has been mentioned about how the hook ups were made (4:25). He did not explain why he did that. A previous review said it was because of the delay in receiving hot water. Pretty expensive way to solve that inconvenience.
You did not make it clear if you hooked the mini water heater to the cold angle stop or the hot angle stop from the house
Dylan Pruitt what the hell is an , angle stop?
@@davetaylor2449 I think he means shut off valve, but it's anybody's guess
@@wayne3340 That's what that valve is called.
use cold water problem solved no need for hot water
