Ok, yu said two 40 amp brkrs, im confused, im assuming yu are referring to a double pole brkr as two breakers, very confusing😮
How long does the hot water last? For example when the shower is running.
Propane tankless is way cheaper
That looks surprisingly simple! Much easier than replacing my gas water tank!!
Hello Sir or Madam,
I am purchasing engineer and working in a shipyard company and we will give order water heater. Could you please share email address of sales department of the United States ? I could not find it at website.
Thank you so much in advance.
Hey Jeff, I also live in central VA around the Richmond area. I just bought a 24 kw. It's sounds like I got a unit way to big for my home
We focus on Electric tankless water heaters and are looking for testers to shoot videos. We look forward to collaborating with you and hearing back from you.
Looks like I got a bad element on the same model. Looking for replacement if I can on this model.
Jeff Rheem is saying you have to drain this water heater every 6-12 months.
No pressure relief valve
E5 is a ‘water flow is too fast’ error which shuts off the heating elements. Any E number is an error.
I’ve been using nothing but the braided type hoses since they came out. The reason yours leaked was because the connection to the water heater was not tight enough.
Where was the disconnect? Hummm
Got mine installed today thanks to your video!
Thank You
Go Bills!!
Your hair looks like someone peed on it and you let it dry like that. Why do you wear your hair like that? It looks kinda stoopid.
Hose connection sizes and wire gauge would have been helpful.Thanks for making this.
Great video. A neighbor was just quoted $5000 to replace his with a unit that costs $1500. I figured since it is a replacement it should be maybe 2-3 hours of labor … which would amount to about $1100+/hr. What am I missing? Is it really that difficult to replace a unit?
GO BILLS!
I don’t like that it requires electricity. Are there models that don’t?
Are they ok with well water ?
Jeff, you stated you connected one white wire to one side of the breaker and the black wire to the other side. My understanding is it doesn't matter what side the white or black wire goes on the breaker, because both wires supply power to the unit. Do I have it wrong? or that's your preferred method. My second question is which unit would you recommend the Rhem 18KW of the Theromate 18KW. Thank you for your time.
So cool man!!! I have to get one!
I just put one of these in. The sinks are all super hot but the shower is still cold.
Where are the vents to the outside?
What was your inlet water temperature and how many faucets/ showers etc. I’m in upstate ny looking at this unit . Only me in the home . Thk you Jeff
Nice. Good to know about the brass importance.
Do they have a drain in the case of cold weather, going for a vacation?
Gooooo Buffalo!!!🦬
How many amps at 240 watts does it draw?
can I install this unit under the house in the crawl space approximately where my tank hot water heater is located.
You should phase the white to red or blue and never trust a hot stick the can be unreliable they could f u up
You didn't show the most important piece which is hanging it
Great information! Thank you.
I need, desperately , to replace my very old water heat tank to a tankless. It's only for my shower and kitchen sink in my small 1b/1b, "55" and old condo apt. (I have no appliances, like dishwasher or laundry machine). I checked with the Condo Association and is permitted to switch. What size of thankless water heater you suggest . ( I'm in Sunrise, FL)
This type of water heater consumes an incredible amount of electricity.
When a handyman installs a tankless …..
How would you service the water heater without hose bibs?
Lets just admit that the Bills mini helmet was the star of this video!
Do I need an expansion tank for this electric on demand unit?
Anyone know where the reset button is?
Never use Teflon tape on fittings unless that have a o ring or a gasket those are called mechanical sealing use tape only on fittings that have NPT threads
Proud Buffaloian my pops is from Buffalo 🤙🏿
ball valve is backwards.
Is it possible to change the element
