ᐅ Cabinet with air-to-water heat pump and water storage tank. Does anyone know this system?

Today, we had another energy consultation. Once again, we ended up a bit more confused than before.

Among other things, we were told about a heating option we hadn’t heard of before. It involves a cabinet that acts as a kind of heating center: it contains an air-source heat pump, equipped with a hot water storage tank and connected to a decentralized ventilation system.

The warm air is ‘distributed’ by the ventilation system. The entire cabinet costs around 20,000 € and requires very little maintenance.

To me, this sounds ideal. We could install our preferred wood flooring without underfloor heating, save a lot of money, and expect less maintenance.

I can’t find any useful information about this system online. Does anyone know about this simple setup? And what are the pros and cons?

Me too. It feels like the initial problems are gone. The manufacturer isn’t fully satisfied with something, probably hardware, so a service technician will come. The system has been providing consistent readings since February 2017 and is being monitored.

Your passive cooling system sounds interesting

@Lucrezia
I think the concept is good. However, I wouldn’t install the system in your case. You only have one temperature zone in the house. How does it work for you in practice? You probably need different temperatures in various areas, like cooler settings in the kitchen or when holding seminars.

OT: I checked again, with typical or many controlled residential ventilation systems with cross-flow heat exchangers, the summer bypass is not manual. This means that during the day, heat recovery runs and warm air is cooled, while at night, the cooler air is supplied directly into the house.

We have the Tecalor THZ504, and it runs great and efficiently even at 1000 m above sea level (3300 ft) in a 55 cm (22 inch) wall house with 165 m² (1776 ft²). We use less electricity than our neighbor, who has two separate units in a one-story bungalow.

Then the system suits your needs. How is it for you with summer mode?

Thanks for the tip, Haydee! If the temperature cannot be controlled separately, it really isn’t suitable for us.
