ᐅ Manufacturer Recommendation: Air-to-Water Heat Pump + Central Ventilation System

Hello,

After a few detours, we are now heading toward starting construction in August 2022... The house will have 160sqm (1,722 sqft) of living space without a basement. The ceilings will be dropped. We are aiming for KfW 40 or 40+ standard.

We will probably build with a general contractor but might subcontract some trades ourselves if something doesn’t immediately meet our expectations.

We visited a building trade fair again over the weekend... The heating installers all preferred to install their “house brand” manufacturer.

We definitely want a modulating heat pump and a central ventilation system with heat recovery and an enthalpy heat exchanger.

Which manufacturers should we consider? We prefer to invest a bit more upfront for an efficient and durable unit.

At the fair, we were very impressed with Vaillant. However, the brand name on the devices doesn’t really matter to us — reliability and efficiency are the priority.

If any further information is needed, just let us know.

Thanks in advance

Ventilation system, for example Helios or Zehnder.

Is it okay if both devices are not from the same manufacturer?

No problem at all. They are actually not related to each other.

Ah, okay, I thought they might communicate with each other.
How are the Vaillant heat pumps in terms of price/performance?
The ventilation unit already had the humidity recovery feature, which is definitely worth keeping.

What is your opinion on the combination of Nibe and Zehnder?
