In my upcoming installation I don't really need these, but for sure, it would be great with a solid state design, which doesn't require much maintenance, if any at all. And at the same time, increasing the efficiency from 45 to 55 %, would make it awesome. All we need is that the price will be competitive too.
I would like to use it in future projects, in the current one I am working on, there is mandatory connection to a common central heating system anyway (natural gas fired). Heat pumps are mainly useful when the temperature increase required is not too wide a gap - giving a high CoP.
