Heat pumps can save you more on your heating bills
If you're replacing an oil, LPG or oil system - but might not lead to great savings if you are on the gas network.
A well-insulated house is essential to best optimise the heat generated by your ground source heat pump, otherwise the heat the pump generates escapes more easily. The heat produced by a ground source heat pump comes at a lower temperature than other forms of heating. This makes it best suited to underfloor heating, which requires lower temperatures, rather than radiators (or, if radiators are used, they should be properly sized).
