Hello everyone,
The next big step in our new construction planning is coming up --> heating!
We have decided that we want an air-to-water heat pump combined with a central mechanical ventilation with heat recovery system due to various factors. Now, of course, the question arises:
- What is a good combination with a central mechanical ventilation with heat recovery system? Are there devices that work well together? What should we pay attention to?
- Which type (indoor installation / outdoor installation / split system)?
- Which manufacturer / which model?
- Other things to watch out for?
Information about our new build that might be relevant for the technical equipment:
- Construction is planned to start in February/March 2021, but the government subsidy application (e.g., BAFA funding) must be submitted on time
- Single-family house with basement – 150m² (1,615 sq ft)
- Building material: brick
- Underfloor heating only on the ground floor and first floor
- Planned for a future family of four (2 adults and 2 children)
I appreciate any help, as this topic is really broad, there are too many models on the market, and too many differing opinions from construction companies, who of course mostly sell what gives them the highest commissions...

It’s clearly stated: COMMON control!
This means both units must be operable via a shared control unit.Exactly, that’s why the question is whether it’s worthwhile or if certain models can be recommended.
I have received a quote from my heating technician for a Vaillant Arotherm plus and recoVAIR ventilation system, as these two can communicate with each other via their own BUS system. Otherwise, according to him, a KNX system would be necessary, which discouraged me because of the initial costs.
I am not sure if this statement is accurate and have not made a decision yet.

Choose both from a manufacturer that offers a control system eligible for BAFA funding.
Choose a modulating heat pump with a low minimum output and a maximum output that matches the heating load.
Choose what the heating installer you trust uses.
MUCH MORE IMPORTANTLY, make sure the underfloor heating is properly designed.

Basically, almost every company offers me the Viessmann Vitocal 200-S. But after consulting with several heating installers, almost all of them are unhappy with Viessmann and recommend Weishaupt or Stiebel Eltron instead. One recommends indoor installation, another says the split heat pump is best, and so on…
It’s similar with ventilation systems — there are so many pros and cons for every type that dealing with it has slowly become genuinely frustrating.
