Welcome to our dedicated thread for air-to-air heat pumps and air conditioning in UK homes, covering both heating and cooling.

Whether you’re considering your first system, comparing installation quotes or already have one and need a little help, post your general questions here. We’re interested in the everyday experience as much as the equipment like how comfortably it heats or cools your home, what it costs to run and whether you’d make the same choices again.

If you want more focused replies to your particular project please start a new deviated thread instead. Give us a little background about your home and what you’re hoping to achieve, along with the make and model if you already have a system or quotation, so members can offer more useful replies.

And if you’ve been living with air-to-air for a while, please share what you’ve learned here. Your experience could help someone else make a much more confident decision.

To kick things off, here’s our Homeowners’ Q&A podcast with Simon Baseden, covering the practicalities of using air-to-air for heating and cooling, which homes it suits and some of the less obvious considerations around hot water and the BUS grant.

Have a watch and let us know what you think.

Our latest Homeowners’ Q&A episode has just dropped, where I was once again joined by Simon Baseden (@ashp-bobba) to compare air-to-air and air-to-water heat pumps for UK homes.

We look beyond the headline installation prices to ask whether A2A can genuinely replace a boiler and heat the whole house (including bedrooms with the doors closed) while exploring heat loss, sizing, cooling and the design mistakes homeowners should watch out for.

Thanks for that, quite interesting.

I liked the bit about judging the quality of installers by their vans. I was quite surprised when one of my neighbours beat me to getting a heat pump. The people who installed their A2W system turned up in a couple of beat up vans.

Of course I don't know that it's a bad installation. Still I'm a little concerned that the pipes into the house (primaries?) are only 22mm. The outdoor unit looks enormous but I checked and it's a US brand TCL which use the same case for anything from 6-16kW. So it may not be over sized. 

I haven't quizzed them about the details of their system. All I know is it was in response to a leaflet through the door offering to replace their boiler 'for nowt' i.e. all covered by the BUS grant. Well it is Yorkshire...

The only constructive thing I can think to do is see if they've looked into suitable tariffs. Also maybe ask how it's configured, flow temperature, weather compensation.. etc.. Not my problem but they're nice people.

I hope it's not the same people who make the awful TV sets
