solar heat pump water heater
how do I build my own ground source heat pump?
I know it’s possible to make a solar water heater using the heat exchanger from an old refridgerator, I have the plans for that already, but can anyone please tell me how to connect a fridge heat exchanger to a geothermal underfloor heating system. I can’t afford 4,000 – 10,000 euros to buy one, surely I can make my own!
If you have any links then please give those too.
Thank you
im a tad bit confused if this is one project youre referring to or two or three even.
I understand the solar water heater from a fridge heat exchange. I can comprehend the underfloor heating system connection to said heat exchange? Is the geothermal part a separate idea?
Typically a geothermal heating system is one thing, the idea being heat is removed from the ground in the winter and pumped into the ground in the summer. These typically involve fairly deep wells.
If what youre asking is how to connect the different coils in the fridge to pump heat between the solar heater and the underfloor system, I just have to ask why not just use water as a coolant and a small pump to move the heat?
For sources, look up popular science (magazine). Within the last 2 issues, one of the editors wrote an article on adding a geothermal heat pump to his house he is building. It is rather informative and you might be able to find it online at their website.
IMHO, if you cannot afford to buy even the cheapest professionally manufactured system, then you should stay clear of any “green” projects that involve holes in the ground deeper than 2 feet.
