Don’t have it but would have if we had the cash and space. Get a heat recovery system for your shower water while you’re at it
Also who’s doing the ASHP design & install? Make sure they know their onions. Ours works but could have been more optimised had the installer cared & I had had six more months of research to become the ASHP expert I am today 🥴

All that said it does work and seems to be surprisingly cheap to run. Doesn’t have to work too hard as there’s only two of us and the house is quite well insulated, but on Agile Octopus and the Homely optimised to use the cheapest electricity prices (we got paid a few pence to heat our house the other night) it’s only like £60 a month for heating, hot water and all other elec. We’ll see when a couple of weeks of sub zero comes along in Jan.
Not in a house, but in a flat that we lived in for 3 years. They're really fantastic, it makes drying laundry an absolute dream, without using a tumble dryer or a dehumidifier. The only downside we ever noticed is that house plants mostly tended to get quite unhappy as the air is so dry.

Yep, I've paid to have an MVHR installed in a Passivhaus:
Zehnder ComfoAir Q 350, external designer, rigid ducting, non-radial.
Expensive, but works very well.I'm now attempting a DIY MVHR in a Victorian restoration:
Zehnder ComfoAir 350, self-designed (to building regs), semi-rigid, radial.
Very cheap by comparison! Still a year off completion, but should work very well...

Pressed go for ASHP installation as part of house extension. Getting Vaillant unit. Very hyped.
Has anyone here got a MVHR system in their house? We’re considering getting one installed as part of the building works, it’s now or never as all the floors, ceilings and walls are open.
