I am going to go and look at a used Geo thermo heat pump tomorrow. It is a older Terra Thermo or so I am told. Its a add on system...needs connected to a furnace, it makes hot air not water. He is asking $200 for it. May need some R22 added because it leaked some out when he took it out.
He had it running a total loss system...well water. I will be using it in a slinky set-up closed loop.

Anything I should be on the look-out for?

I know it may be old but where else can you get a working geothermo heat pump for $200?? This will be used to heat my garage when I am working out the so I don't need it warm all the time. My loop temp there got to a low of 38F last winter...it is 56F right now with nothing hooked up to it. 1200ft of pipe in the ground as a slinky coil.

I could try it out in the house this winter by drawing water out of a heated tank, 800gal...how high of heat could one of these stand for the input side? Up to 80F or more?
