    1. Air conditioners in UK houses are pretty weird and complicated
    2. Potentially having to rip out aall the (usually underfloor) pipe work and replace all your radiator is pretty complicated, compared to switching out the existing gas-fed box on the wall
    3. Working out the capacity needed to heat your home is pretty complicated
    4. Finding the space outside in a small urban garden than can take the unit, without annoying the neighbours next door with the noise can be pretty complicated.

      The capacity calculations and potential noise complaints are the big ones imho.

      I can definitely see issues with installers not giving a toss about noise, and having to be chased later.

      Calculating capacity isn’t that complicated, you can look everything up to work it out (wmk losses, etc.), but it is a step up from the current “slap a new boiler in” mentality.

      And I wouldn’t be surprised if most heating techs don’t consider requirement at all when changing a boiler, they’ll just put in a big one, and run the rads at 70 if the client complains.

      There is talk about ASHPs that can still maintain efficiency at higher temps, which may help a lot of households avoid changing the radiators too. But it’s still early days.

      You can leave the pipes there. They’re not doing much. Radiators aren’t much threat either, unless you trip into one.

        Not really. Since the radiators operate at a substantially lower temperature, you may well have to replace them - you need larger, more efficient radiators than may be typical with gas-fired systems

          Oh, using the same system, instead of switching to forced air.

          … why does efficiency matter if the heat stays in the house? They’re just always-warm instead of sometimes-hot, yeah?
