You aren't gonna believe what I just bought off of Craigs List...
I just got an ASHP that heats water! It is a unit that is meant to be plumbed into a hot water heater. It is a 12,000 BTU unit that has no tank. You supply the tank. In the event that the ASHP can't supply the amount of heat (because the air temp is too low), it turns the function of making hot water over to resistance heat.
The guy I bought it from paid $1,400 for it new, and he tried to use it to do hydronic heating... only thing is he followed the 'normal' rules of thumb for a hydronic (wide PEX spacings, staple up, etc.) system that is going to use fossil fuel and can supply feed temperatures in the range of 160F. He did staple up, spreader plates, etc. Trouble is his heat pump can only supply water up to 125F. So his system never kept the house warm and comfortable.
So, long story short, the unit is a couple of years old, and I got it for $400.
And I have been insulating my house and researching floor configurations and testing computer models for feed temperatures in the range of 95F... This thing can happen!
