Hello dear forum members,
Through a variety of professional magazines I ordered for our new build in spring 2015, I came across the air-to-water heat pump LWZ 504 from Stibel Eltron. According to Stibel, this unit offers the following:
"The compact LWZ 504 provides all the comfort expected from an energy-efficient house. The system draws energy for pleasant indoor temperatures and hot water from the outside air. Modern ventilation management ensures that the heat stays inside the building. It recovers up to 90% of the heat from the exhaust air. This allows a comfortable, healthy atmosphere to be combined with high efficiency. The demand-controlled inverter technology also ensures high efficiency. It produces exactly the amount of heat currently needed. High performance values can be achieved even at low temperatures. Energy-saving operation is supported by the modern high-efficiency heating circulation pump and excellent insulation of the hot water storage tank. For those who want to be even more independent from rising energy costs, the LWZ 504 can be operated with self-generated photovoltaic electricity using the appropriate accessories (ISG + SEE). The large, intuitive matrix display ensures that the modern technology in the award-winning design is easy to operate."
Key Features
I understand that this great system naturally comes at a price, but I would like to ask the experts among you—air-to-water heat pump owners as well as heating engineers—for advice or experience with such units. Ideally, it would be great if someone already has this exact pump installed in their basement :-)
Thank you in advance for your responses.
Best regards,
Martin

This system is not an air heating unit! You only have the heat recovery part of the controlled residential ventilation system.Okay, then it might be the LWZ604 Air or another model? I was actually interested in taking a closer look at a unit like that.pagoni2020 schrieb:

But unlike the 304/404/504, which are all air-to-water heat pumps designed for underfloor heating, the 604 follows a different concept.

That website is really confusing; at least I can't figure out which units are air heating plus cooling.
