I can not get the water heater to get above 100 degrees even though it’s set for 140. Doesn’t get hot enough.

Works great did a lot of research on tankless hot water heaters to make sure I get full water pressure taking a shower I live in North Central Florida with well water around 72 and I have 40 60 water pressure well pump I'm able to turn up hot water and cold water at full pressure seems like I have more water pressure because it's not going through a hot water heater tank ... show more

This unit should get a five star evaluation but, longevity has not been tested yet. Other similar unit(other brand). Only lasted 3 years. I gave that one a five star, how was I to know?

  • plenty of hot water for showering and general use
hot water tank broke so needed a new system. tankless water power limited to existing wiring. this tankless system works perfectly. and since there is no tank for nasty bacteria to grow I can set the temperature lower, at 105F, and save money. Only heating water I use. Also, no nasty gases (hydrogen) and no need for an expansion tank. And saved me $2k-$3k as it was simple to install myself. Win win win win. ... show more
