Air Source Heat Pumps

One of your most requested ‘wonder-products’ so far. Heat pumps are promising to not only make our houses greener but to also cut our energy bills. But will they? The Government says every home could have one and have reintroduced grants to help buy them. However Nick wants to know if an air source heat pump would be suitable for the 1930s house he’s about to move into with his family. Given the higher cost of the unit and the extra insulation he needs, will he actually be better off with a new combi boiler instead? Greg speaks to experts, does a survey on his own home and gets Nick answers so he can decide if a heat pump, for him, would be the best thing since sliced bread. Do you have a suggestion of a ‘wonder-product’ making a bold claim that Greg can investigate next?
