Re: Plastic uninion at copper line
Eric,
It's a shame when those heat recovery units are disconnected and abandoned.
Typically, this is done by a/c technicians who scratch their heads when replacing the condenser unit and say 'what is that thing'.
They work VERY WELL if you use a/c or heat pump.
In South Florida, I know people would would turn off their water heater breaker and just use that to heat the water with.
We had one on our house down there and never had a problem with hot water, even when I did turn the breaker off to see what effect it had.
If you are in an area where the a/c runs during the day but not at night, then you would want to leave the breaker on, so the water heater kicks in at night as needed.
