Controlled residential ventilation: enthalpy or standard heat exchanger

Hello,

we are planning a Zehnder Q350 for our new building and now we are faced with the decision whether it should have enthalpy or a standard heat exchanger. The question now is whether the enthalpy can quickly and properly remove the construction residual moisture. Enthalpy has an additional cost of about €650, retrofitting would cost €800. What is recommended here and are there any experiences regarding this?

Thank you very much!

Isn't the enthalpy exchanger not for moisture recovery? So rather counterproductive?

I would consider having both in order to be able to switch between them in summer and winter.

Yes, but at some point the residual moisture in the building is gone and then you often hear about 20-30% humidity, which is not exactly healthy. Replacing in summer is not necessary as far as I know since the Q350 has a bypass.

Exchange because: in summer the humidity is high, so it should be removed a bit. In winter, however, you want to get it back. It actually has nothing to do with the bypass. At least I wouldn't understand it that way.

Exchanging it in summer is nonsense...we don’t have tropics here with 70% rFI etc. I would have an enthalpy exchanger installed...the investment will pay off...

The excess moisture is still drained away via the condensate drain, so with the enthalpy exchanger you are killing two birds with one stone.

: Do you mean with the excess moisture that the enthalpy exchanger maintains a certain value of air humidity, e.g. 45%, and discharges the rest?
