Post heater MVHR Comfoclime/ComfoAir combination?

[Nic]

Hi

anyone got any experience with the post heating combination that Paul heat recovery are recommending as an option to my build?

Really depends on your house heat load. At Passivhaus flow rates from the MVHR, this kind of heat supply is limited to 10W/m2 of the property (statement from Passivhaus is any more than that the air smells burnt).

 

Also they have a quite high water flow temperature, so not that good for CoP if using a heat pump, in fact not suitable for a heat pump as the Paul page has a water flow temp of 70 or 75 going in.
