You mentioned 55 gal bbl. About 500# of water. Say you can cool the water down to 75F during the day getting the heat out, heat it up to 125 F during off peak

That is 25,000 BTU; however, you have also cooled your other bbl down 50F, etc..
do you see where this discussion is headed?
Eventually I think I would like to have a 275 gallon tote each for the hot and cold side, and a larger compressor, maybe multiple compressors. In the winter I need a lot of dehumidification in an unheated building, I want to use the cold water for that. I can use the hot water to heat a different heated space. Then, in the summer, I'll cool the heated space, and probably use a pump and dump type geothermal system for the hot side. Don't have humidity issues in the summer...

I want to use the 55 gallon drums to experiment with since it will be relatively easy to weigh the water and accurately calculate the BTUs on each side.

Somehow I hope to also pull DHW out of this too. Every Sunday and holiday power is "off peak" for a full 24 hours, so it would be nice if I could take advantage of that.

Very nice! With ebay it's just a matter of actually finding that thing you know they must have...
