I think i need to foller that thread for under a hundred bucks.

I just found one for 250 bucks needs what he said is EEV valve or a temp sensor.

Or a brand new one a guy has that bought a on demand water heater instead. for 600

Yea it has a ethernet port.
Heres what i found.
GE also integrated an ethernet port on the control panel. This will enable the unit to connect to GE’s Nucleus Home Manager System, integrating with your home network. Connecting to this system will allow your GeoSpring water heater to send alerts if the device needs maintenance. You can also change the water temperature from an app, and track energy consumption on your computer.

With a donated water heater and a couple of window units sitting in line, I believe I can tackle one of these for under $100.
Well, so much for that idea. The owner went and priced replacement water heaters. After that, he changed his tune. Need less to say, I'm not going to be getting that one. It is well worth repairing. He said a 40 gallon, glass-tank replacement was in the range of like 600 bucks.

I'm just on the edge of my seat, waiting for that call...

Any reason you couldn't convert your existing water heater or build a unit that works with it?

If you make a unit similar to mine, no modifications to the tank and minimal plumbing work are needed. It just piggybacks onto an existing sink or washer hookup.

Details? Thread reference?

I have questions, but they may be answered elsewhere already.

I could possibly do this. I have an amped up dehumidifier sitting around already. I built it as a proof of concept that I could run it backwards to provide heat.

Somewhat clothed:

It did its job well for its size. The evaporator no longer froze every 1/2 hour and it put out lots more heat. Its heart is a Rechi 5000 btu, just like in all the 5000 btu window a/c units.

Its big brother (10500 btu):

It heated the house quite well, sucking in ambient (room) air, blowing cold air outdoors and warm air indoors. She said it sounded like a jet engine, so it had to be exiled...

You do it pretty much the same as the conversions often done here, but you use a heat exchanger instead of coiling tubing in a tank, then adding a pump to move the water.
