Cabinet with air-water heat pump, water storage.. Does anyone know it?

Me too. It feels like the teething problems are gone. The manufacturer is not satisfied with something, probably hardware, a service technician is coming. The system has been delivering values continuously since 2/17 and is being monitored.

Your passive cooling sounds interesting


I like the concept. However, I would not install the system with you. You only have one temperature in the house. How is it for you in practice? You certainly need different temperatures than in the kitchen, or during seminars you turn it down.

OT: I checked again, in typical or many controlled residential ventilation systems with crossflow heat exchangers, the summer bypass is not manual, i.e., during the day the heat recovery runs and warm air is cooled, at night the cooler air comes directly into the house.

We have the Tecalor THZ504 and it runs great and efficiently even at 1000m above sea level in a 55s house with 165m2. We use less electricity than our neighbor with 2 separate units in a single-story bungalow.

Then the system suits you. How is it with you regarding [Sommermodus]?

Thank you for the tip, Haydee! If the temperature cannot be controlled separately, it is indeed not for us..
