Air to Air Heat Pumps

dgclimatecontrol · 2025-08-21T11:30:23Z

As an installer and user of these systems for 30 years, Ive found any many cases they offer lower cost heating, fast and effective heating and virtually guaranteed to work (plus cost effective to buy) What is other peoples experience?

Good article. I was not aware such a high percentage of the heat pumps in the Nordics are A2A. But buildings are clearly not all the same. It seems with open plan being more prevalent there, it probably reduces the cost of deploying A2A and so becomes more appealing.

Not so sure about why Germany and Poland are more into A2W?

The UK market is hopefully going to grow further but given open plan is not very common in our homes and our weather being so different, it is not obvious A2A would become prevalent. But I have no crystal ball.

Building shape and form definitely is an impact, but a lot of modern UK building is effectively open plan because the internal walls are not real walls. It's a highly insulated box with dividers in it.

There are definitely cases where one or the other is a big win and we need installers to be more proactive about offering both. Right now we have air/water people and air/air people but very few places you can get a "We could do this or that, here's the trade offs"
