Secondary heat source needed for heatpump - which to go for?

    I have been having trouble with my air-to-water heatpump. It is working fine as such, but is just not strong enough to heat our house. I have just spoken to the main suppliers for the system and they confirm this view.

    Basically, I now need to install a secondary heat source to boost the heatpump on cold days. Does anybody know what would work best? (e.g. oil-fired boiler, etc.).

    Many thanks for any replies.

    Who spec'd the system for the house?

    The unit should have being sized properly and there would be no need for a secondary system.

    If you are looking for a secondary system, what are you heating rads or underfloor? You could look at tie'in in the boiler to come in on some sort of stat system.

    Id first look at the heap pump itself, i know its getting old and time is an issue, but heat pumps are supposed to supply you with your full heating needs, this one isnt - i suspect someone made a mess of the specing of the unit for the house.

    I agree, someone somewhere f***ed up bigtime. We bought the house with the system already installed.

    There is underfloor heating downstairs and rads upstairs. Downstairs is controlled by room stats (6 in total). The rads upstairs are on a timer, comes on for about 2-3 hours per day.

    My advice to you is to get an energy rating done on your home.

    Then, consider making your home more efficent insulation wise.

    The heat pump may be suitible if you can decrease the heatloss of your house.

    Record,

    what is the heat output rating of your heat pump in kWhr?

    e.g. 10 kWhr etc

    If it say 10 kWHr, and you have a D rated house,
    then it may be adequate if you could increase your rating to say a B3 or C1.
