ᐅ Mechanical ventilation with heat recovery using enthalpy or rotary heat exchangers

Hello everyone,
we are currently planning our new build. The house will have approximately 175 square meters (1880 square feet) of living space.
At the moment, we are researching ventilation systems. We want a central ventilation system with heat recovery and would like to ask if you can recommend any manufacturers or models.
It is important for us to have an efficient ventilation system with quiet operation as well as low maintenance costs (filter changes).
Furthermore, we are interested in whether you generally recommend a central ventilation system with an enthalpy exchanger or with a rotary heat exchanger. Both have their advantages and disadvantages.
Thank you very much for your help.
Good luck

What are your CO2 levels? And how do you measure the humidity?
At 50-55%, it’s likely that you are ventilating very sparingly, which could also explain using such a small device, or the house is very small but has many people living in it.
Based on calculations, such values are actually not possible with current outdoor humidity levels.

Air exchange rate 0.4 Well, that is hardly achievable with the device. CO2 levels are actually the important factor for setting the ventilation.
The air exchange rate is probably more like 0.2 to 0.3. You would need to produce about 8 liters (0.28 cubic feet) of water vapor per day inside the house, which is somewhat realistic.

You probably mean hygrometers. A hydrometer actually measures the specific gravity or density of liquids.
Smartass mode OFF
