using multiple heat sinks for a water source heat pump, I.E. slab, pool, pond, geo...
I am considering a water source heat pump for energy efficiency, on a home I will buy in the near future. I would likely install the system myself, as I do work at an AC company, and know the basics, but need advice on the more advanced sides of the equations. What would be my best source for a heat sink / where to put the heat to cool the home? Have a hole drilled? Could I put some of the heat into a hot tub, or pool? would a concrete slab in a shaded area provide an adequate heat sink? Can I setup controls, such as DDC controls, so switch between the best heatsink available, say, if I did a geothermal loop, a pool/pond loop, and a concrete slab loop?
Are geothermal loops a good choice everywhere, or does the water table play a role in the ultimate effiency of the unit?
In the winter, I'd like to use a stained black slab as the heat source, as it should soak up a good portion of the sun's heat.
Any ideas, arguments, warnings, or advice would be greatly appriciated.
Actually, using the pool as a heat sink should work out pretty well for the first 300,000-600,000 btu of heat rejection per day, depending on the the size, shade conditions, etc. of the pool. Make sure to use a titanium heat exchanger for the pool water!
