u/musing_and_moaning

In an A1 rated house, survived the heatwave just about. Followed all the guidelines of closing all the windows by a certain time, sheets on the outside to keep the solar radiation off etc, still had to move with our newborn to the living room and the internal temp was 26-29°C.

So started to look at portable A/C.

Then saw posts here about Air-to-Air. Now we have Air-to-Water, although it costs us a bomb to heat the house with it (I think it was undersized for the house).

Does it make any sense to get Air-to-Air installed to heat/cool 2-3 rooms in the house? Or just get the portable A/C?
