Yes the device is faulty. the unit should not heat water unless a tap is turned on. Call in a service rep to assess the problem. Do it quickly your description doesn't sound good.

Please rate this response and Good Luck Phil

Hi,
The unit is plugged up with mineral buildup from the water going through it... it will need to be cleaned internally....this is done by running an acid solution through it to clean out the mineral buildup...

Then it will work again...

Hot Water Hot to Cold And back. I had that problem for 2 years. I had a very large shower head from the time I installed the tank-less hot water heater and the water temp would change from one extreme to another. Over time my shower head had stopped working as well as it did so I bought a smaller shower head and installed it and amazingly my water temperature quit changing temperature. I now turn my water to what temp I want and it stays there. It's been working correctly for 6 months now ... until yesterday and it quit working completely which is the reason I'm on here. lol

I just replaced the circuit board, and the water gets warm, but not hot.


Problem might be crossover from failed single-handle faucet cartridge:

Electric bill doubled last month, and we've had the Powerstar AE125 tankless electric for over a year. There are no leaky faucets.


There are a lot of other things that eat electricity. Like space heater and using ovens for heat. Heat pump.Central heat fan running all the time. House lights left on. Outside flood lights. Clothes washer using HOT water. Look around real good. It all adds up. Also the power co. may be charging more for "fuel" costs surcharges. Here in GA I'm paying a bit more now to pay for a nuclear power plant.
