    Duel purpose heat pump

    Does anyone make an air source heat pump that not only will heat the house (forced air) but also heat water.
    I'm thinking when the heating demand for the house has been met the heat pump could then heat potable water or infloor in the garage

    So what happens when the outdoor temp gets too cold for the HP to heat the house. And it doesn't stop running to heat the house. How do you heat this water then.

    They still make desuperheaters.

    When it gets to cold (below 10-15f) you would need some alternative source of heat but I'm thinking fall and spring.
    If I am going to put in a HP to heat the house it would be good to still utilize it to heat the garage in floor when the house comes up to temp.
    We have been having very mild weather here lately, still haven't been able to put the sweaters away.

    That would take a large and expensive heat exchanger to do what you want using water as the medium for the garage. Along with control system.
