Well, I bought it but have to run back and get it with a trailer. The guy had it running a total loss system in a 40 ft well pumping 8 gal a min. He got tired of replacing well pumps and pressure tanks. Claimed he could heat his house for $40 a month with oil or wood as back-up or when it got real cold.
It looks real clean and you can clean out the heat exchanger on this one. Paid $175 for it and he is throwing in a flow regulator and few other things.
Said it was a 4 ton unit, the compressor is a big sucker! I have a big 220volt 24-27k BTU window unit that maybe use that compressor and cap off the 4 ton for future expansion. He was pulling 5 degrees out of the water while running at 8 GPM Being I have only 1,200 feet of pipe in the ground it might cycle too much. I have room to put another 1,200 maybe 1,800 ft more...if I can get some good results out of the first loop.
Not much to the inside of it, no electronics just a pressure switch and couple of relays. If I did have it opened up and switch compressor I would put in a reversing valve so I could cool with it also.
Can't believe the draw...28 amps! What would running amps average?
Any input or ideas?
