    Heat pump and a Boiler

    Is it feasible to have a heat pump but instead of using electric back up use a hot water coil off a boiler? Does this work? And how exactly woulf you hook it up? Is the hot water controlled by the emergency heat on the stat or should it be second stage heat. Anybody done this before looking for some help.

    With a relay to control a circ pump and a time delay switch to bring on the fan.

    A few manufacturers that make AC DX coil air handlers with built in hot water coils make it so you just follow the wiring diagram.

    My guess is if you have to ask some of the questions you have, you might look into a contractor in your area who can do it for you .

    How many times must one fix something before it is fixed?

    Why is everyone on this site an a-hole? Ed Janowiak for instance, I realize how a hydro coil works. My question was how to wire in the switching between the heat pump and the hydro coil especially after the temperature drops and the outdoor saftey drops out my compressor. Does anyone other then this D@#% Head know what is the proper way and why?

    Yes. But I would hope your not lockingout the heat pump by temp as much as by economocal balance point.
    Down here, we don't lock out the HP unless it drops below 0°F.
    But, since this is an open forum, I'm not allowed to tell you how to wire it.

    Ed knows what he's talking about, no need to jump on him. He is correct that some of your question are vey basic.

    You owe him an apology.

    I'd prefer thank you as opposed to being called an a-hole.

    This type of question would be answered in detail in the pro section of this website, but is against the rules in the non-pro section.

    Apply for membership to the pro section and not only will I explain how to do it, I'll write up a list of what you need and even show pictures so you can follow along.

    Good luck .
