Water source heat pump loop and hot water system

ChuckChuck Posts: 61Member ✭✭
Water Source heat pump system – I have used a boiler for direct heat add (boiler used only for heat add). I have used a boiler for an indirect heat add (heat exchanger). I don’t think I had a system the hot water system was directly coupled to the heat pump loop (hot water used for entry unit heaters and heating ventilation air). I can’t think of any reason I can’t have the loops directly coupled as long as I have a heat trap. Am I not thinking of something?

(I am talking about a regular water source heat pump loop - not a ground source).

    If the cooling side of the system is an open tower, the constantly added fresh water can destroy the piping/boiler. I would keep the boiler on its own set of piping, whether a direct add or heat exchanger.

    Closed loop.

    Closed circuit cooler. Closed system. I haven't tried to lay it out but the trick part is where to put the expansion tank.
