• 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.

  • 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...

    I’d be very interested to hear more about this. Are you documenting it anywhere?
