Whole house Electric tankless water heaters


I am looking for information on tankless water heaters. I have a 2 1/2 bath house with a dishwasher, clothes washer. The water temperature of my ground water is between 60 & 69 degrees

Most all house instantaneous sites have a app available for you to size the thing. Always op for bigger then what you think you need.

Whole house electric water heaters are a huge power hog. You are likely to require 120 amps to power it. Most homes would require a minimum of a 200amp service to support one. Some all electric homes with signicant electric heat loads might require 300 amps, or more.

The cost of the electric service upgrade can be quite substantial.

I would suggest sticking with a tank type water heater unless you have gas or propane. A gas fired tankless is a different animal than the electric, although even they may mandate some piping upgrades for larger units.

here is a link to one on amazonhttp://www.amazon.com/Ecosmart-ECO-27-Modulating-Technology/dp/B002635ODW/ref=sr_1_2?ie=UTF8&qid=1453580609&sr=8-2&keywords=electric+tankless+water+heaterit uses 3 40 amp breakers....im sure there are other brands out there, but if you have natural gas or propane you would be better off with a tankless that uses one of them, ..im sure there are other brands out there but the electric in a residential setting using standard 220vlts, doesnt seem to give the fast recovery that a gas unit will...

We've had an electric, tankless heater from drakkenusa.com for 4 years, and it's been fine. Our house is a 4/3, and we've had no demand issues, even with the dishwasher on. Also check out Titan brand made here in Miami.

We're a famiky of 4, with frequent dishwasher loads, and the electric bills have not risen at all, in comparison with our days with a 100 gallon tank. If you end up staying with a tank heater, install a timer that costs $50. A lot of people incorrectly leave the heater on all day so that they can have hot water at 7pm, ad that is a huge waste of electricity. An hour of heating is plenty for a family of 4 to take a normal shower and that timer can be programmed to come on/off at whatever time you want; it is also easy to install with some basic skills.

If you had a 100 gallon water heater I can understand my the tankless electric doesn't cost you more . For a family of four, a 50 gallon electric, a 30 gallon gas or oil fired would have been plenty.
