But winter likely everyone's windows are closed, only in summer will those without the heat pump have their windows open, that is of course if that model is bidirectional?
The cost to retro fit fan assisted radiators (as without it would need two one high in room and one low in room as heat raises) and condensate pumps and plumbing, as we find our AC generates around 1 gallon every 90 minutes, is massive.
OK if fitted when the home is built, but retro fit, cost of ripping up flooring and fitting pipes, means for most simply not worth it.
I must admit I did look at the idea of fitting it in one room only, however solar for December

The generators were having problems with last heat wave, so how do they think they will work with the Beast from the East or whatever name they give to it next time?
The battery may keep my oil fired boilers motors running, but no where large enough to do the heating as well.
