Myself! We have the land area here, and I'm building a small (1200 SF) house on the lot across the lane from us, so I want to put a system in both places. I will hire help from time to time, but I want to be responsible for the work and workmanship. Besides, I enjoy working; I don't enjoy watching. We'll see what kind of song I sing after I've dug a kilometer's worth of trenches.
If you search E-Tech W102 heat pump, the top hit just now was "www.etechbyaosmith.com/com_waterheating.html". The page is new, but the product may be on the verge of a revival. I have the catalog and owner's manual for the heat pump. It's odd that one or two don't show up on eBay or somewhere.
I have some questions and thoughts about source loops, so I'll be back on this or other threads. Besides, I've got days and days of reading ahead...mm
