• What makes ASHP good and mini-split bad?

  • They're the same thing.

    I guess the point @ectoplasmosis is making is that it's ongoing energy cost rather than the reduced impact of shade, solar film or external shutters.

    I can certainly highly recommend AC units but we have solar & battery so have very limited grid usage and even that's with Octopus so renewable.

  • As @Soul said, they’re both types of ASHP: one is air-to-water, the other is air-to-air.

    Air-to-air units used for cooling are completely fine, but are frowned upon when used as a sledgehammer before tackling the primary causes of solar gain first, using passive methods as mentioned above.

  • I think mini-splits are often smaller units so are just inherently less effective
