Customer Questions & Answers

Do these tankless water heater need DE winterizing

Asked by: Dee
These units should not be in a freezing environment! There is always some water left in the lower sections of each sealed cooper tank. Freezing can damage and ruin the tanks and is not covered under warranty. The best bet, if unit is in a 3 season cabin or vacation home, is to cap off the electrical and plumbing lines, take them off the wall and take them with you.

Rated 4 out of 5 by from Electric tankless water heater I installed this unit as an upgrade for a kitchen remodel. So far it work great and supplies hot water for the entire house.

Rated 4 out of 5 by from So far so good I have had a few months now. This replaced a 50 gal tank. Electrician needed to install sub panel, add breakers, run wiring, and upsize home main breaker to 200amps. Did the plumbing myself. Flow is fine even in tub. Slight fluctuation in temperature when my boyfriend uses another fixture simultaneously, despite the claim to maintain constant temp. That is the reason for 4 stars. Still, awesome to not run out of hot water and I'm saving money on electric bills- $20-30 per mo.

Rated 5 out of 5 by from Unlimited hot water I had this unit installed and had hot water in minutes. The electrician charged around $600 to run wiring. I did the plumbing and instal myself. It was very easy to put on the wall. I used shark bite fitting. I noticed a savings of about $100 on my last electric bill but I'll try to update this review because it went from very cold to average temp outside so I think the heat not being on affected my bill as well. I have high flow shower heads and noticed the pressure was a little less but not that bad. If you run several appliances at one time then the pressure goes down even more. I just don't do wash with hot water while I'm showering and that seems to work fine. Overall I'm very happy. I'm saving money and have unlimited hot water. It gets extremely hot so be careful. Hope this helps. Thanks

Rated 5 out of 5 by from Excellent product! Works well for whole house! Background: We originally had a 50 gallon propane hot water heater, coupled with a hydronic air handler for home heating. The combined usage made for very expensive propane bills, so we decided to upgrade to a tankless system. After reading reviews and doing some homework, we decided this was the best unit for us. Homework: We live in the Pacific Northwest and our inlet temperature is around 40 degrees, so we were concerned that the resultant temperature rise would limit flow beyond usage but this system delivers! When deciding if this system is the right one for you, take into account that you will need room for 3 double throw 50 amp breakers(6 slots) and atleast a 200 amp electrical service to your home. Wiring requires 8/3 wire (w/o ground). If you are atleast somewhat competent with electrical work, you can install this yourself no problem. Took me about a day to do it all myself. The system keeps and maintains 123 degrees comfortably for dishwasher, hydronic furnace, laundry, and shower at same time (although we have low flow energy efficient items). The cons to this system is the expense of copper wire and items required to install. Even if you do it yourself your looking at a couple hundred dollars for just the hardware but in my opinion it will make it up in a few years from not having to heat the water all day and night while its not being used. The next con is that this system requires a larger pull on demand to activate the heating element. It's not an issue really but if you like to just turn hot water to a trickle, this will not work. The last possible con would be its a 28kw system so it's a huge electrical pull when used. Just make sure your home has enough room left over to use this system before you buy it. Just for a reference, I calculated that it will cost us $3.28 for every hour of run time of the water heater. Over all it's a great unit, works as advertised, heat is constant and nice and even regardless of what's being turned on or off. The benefit of the "plus" system vice the other is that this system will automatically throttle pressure to ensure temperature maintains consistency. Good value . I recommend!

Rated 5 out of 5 by from Electric Tankless Water Heater Stiebel Eltron Great product, now for the nuts and bolts. Lets make sure one knows the reason for a tankless. 1) space 2) save money 3) the need for endless hot water. Now lets make sure one knows what it is NOT. Tankless is not instant hot water. For the record it takes longer to get to your faucet or tub than a tank unit. Why b/c of no reservoir and in order to make hot water the unit has to sense flow and how much flow.On electric you have flow determines the amount of current or scales the current back and forth. Gas units the burner uses more gas or less by flow of water. My electric Tempra 29 plus I had to run 3 separate 8 gauge wires. Breakers were 3 x 50 amp double pull. This unit delivering full power for hot water make up,l devours 120 amps. So far one month in I enjoy it. In coming water or ground water temperature in conjunction with how hot you want the water called (rise) dictates what size unit you go with. This will tell you gpm (gallons per minute) the unit will deliver. Beware of your electrical panel. The breaker space needed and service to handle the type and size unit you choose. Typically these should save you 15-20% on your electric bill. I like mine. I choose for space saving and money. One note you can use a small tank and tankless at the same time. The tank would heat water 20 to 30 degrees and the tankless would bring the temperature the rest of the way. I believe you would save money but space would be gone. I have 68 degrees coming in and heat to 118 to 120. If you call for more hot water than it can heat you still get hot but not as hot as you set it. Beats a tank unit when the water just turns cold.Hope this helps
