The Homemade Heat Pump Manifesto

I made something similar to that for my wvo jetta so making a heat exchanger with no pressure ground loop water was my first idea, then I realised my water heater is just on the other side of the wall and I needed something very reliable to hold city water pressure(60-70 psi around here) and high pressure refrigerant, your FPHE looks like the hot ticket.

Thanks for all the info, I will do more searching and email some suppliers on ebay when I start parts gathering for the project, can't wait to see the difference on the kill a watt.

Anyway back to you, any news on the heatpump?
