Comments about 27 kW 240V Electric Tankless Water Heater:

I use this model EcoSmart 27 kW 240V Electric Tankless as a whole house water heater. I live in western Washington, so the temperature here doesn't get much lower than about 25 deg F and input water temp is about 50-55 deg F year round. This unit replaced my bosch AE 125, which was a good unit, that I have had for 8.5 years. It is less expensive than the bosch and seems to work better in several ways, it has a very stable temperature output, 2 showers can be taken at the same time, which together run approximatly 3.5 gpm. temperature adjustment has a digital reading and is accurate at 125 deg F. the hookups were similar to the bosch AE 125, so installation was easy. I have only had this unit for a 3 weeks, but so far excellent. No Cons, I will never go back to a tank type system.

Comments about 27 kW 240V Electric Tankless Water Heater:

Installed in one day using .5 PEX. Takes 3 40amp breakers with 8ga wire that was real fun to run. But OMG it was worth it. This unit replaced another unit that could not handle winter water temps. Best advice I can give is you pay for what you get. Could have saved $300 by going with this unit first. Oh yeah you will notice lower electric bills if your moving from a tank water heater, like a lot if it a old one.
