In helping my son with his new (to him---about 10-15 y.o. in house
years) I asked him how his heat pump was working. He insisted it was
only an A/C unit. (Outside Unit is Trane XE100, MOD: TTR036C100A3,
SER: P2645H9FF, Built in 1999. Did not have my coveralls so I did
not go up and look at the air-handler)
Then he showed me in the garage where the ouput from his hot water
heater is split and one line runs through what is obviously a small
circ pump (the return line connects to the input of the heater). He
says this is his heat (He bought this in July).
Anyhoo, have never seen such a set-up but I'm willng to learn. I
assume it has some sort of heat exchanger(s) buried somewhere in the
A/C system (air handler???)
To me, it looks kind of inefficient and very $$$ to operate.
Any advice, links to descriptions on installation, operation,
maintenance of such a system, or whatever else might be enlightening?
