I would like to use a heat pump as a source for hot water for a radiant floor system. I know that there are split systems when using an air handler, so instead I want to purchase a flat plate heat exchanger, connect it to a heat pump, and have an 80 gallon storage tank for the hot water storage. I am looking for a schematic showing me the parts I would need to accomplish this. I know that there are systems being sold that do this, but financially they are out of reach for me. I realize that I would need a heat exchanger, water pump for circulating the water through the tank and exchanger, but beyond that I am at a loss.

Aaa

Along with all the parts and pieces you better hire an engineer to do all the calculations or the system will never work. While it sounds simple it is a very complex setup.

Is this out of reach? GE 50 Gal. Heat Pump Electric Hot Water Heater (GEH50DNSRSA) (http://www.google.com/products/catalog?client=firefox-a&rls=org.mozilla:en-US:official&channel=s&hl=en&q=heat+pump+water+heater&um=1&ie=UTF-8&cid=16203948784313965804&ei=pEEETNyvHsP88Ab7qvDBCQ&sa=X&oi=product_catalog_result&ct=result&resnum=1&ved=0CBsQ8wIwAA#)

Kiss.. that's EXACTLY what he should use. But he will need help with the plumbing since in his own words he is at a loss. Fill/pressure regulator, expansion tank, possibly a manifold... lots of things to consider.
