  • You don't have to be convinced though. The data is there. I've yet to see one of the naysayers of heat pumps actually show me data where a properly installed system isn't providing savings over a gas or oil boiler.

    (That being said I have designed industrial systems whereby there won't be an OpEx saving but in these cases it's because the client has other objectives such as decarbonisation or input energy reduction as a priority).

    This is the hurdle people need to get over though. Everyone wants a new kitchen or conservatory but tell me how the ROI is on these projects?

  • I'm not convinced by how much value they add to a property. The data there seems a bit vague.

    Saying that, if I wanted to install a heat pump I'd need to replace every radiator (they're all a bit underspecced) which would then knock on to a fair bit of redecorating (pipes come out of the walls rather than up through the floor) which would kill any potential ROI.

  • Maybe the energy efficiency cert pushes up the prices, but I think it’s hard to believe either that you’d get at least your money back on what you outlaid
