ᐅ Experiences with the EcoAir 614M Heat Pump by Giersch

Hello, this time I have a technical question. I know, that’s not usual for me. But I really have no idea about this. It’s about the heat pump, because even a butcher’s house needs heating, if it ever gets finished.
The new heating technician offered me 2 units of the EcoAir614M from Giersch for the two semi-detached houses. Has anyone had experience with this?

No experience, but a question for you – what kind of bunkers are you building that require such heat pumps? For KfW 55 standard, any heat pump is sufficient for at least 250 m² (2700 sq ft) of living space.

Don’t be surprised that Hausbau2019 has become Hausbau0815. The account was just blocked, probably due to some critical comments. Of course, it’s possible that I’ll be gone again shortly with this new registration as well.........

We are building without KfW funding. Aerated concrete 36.5cm (14 inches), without external insulation. Two apartments of 220 sqm (2,368 sq ft) each and an additional 200 sqm (2,153 sq ft) waterproof basement with underfloor heating.

Then the performance should be fine.

Sorry, but that’s all I can contribute right now.

OK. Besides the performance, I am also interested in the eligibility for funding, if anyone can provide some information on that. I was told that this depends on the size of the building, the location, and the standardized outdoor conditions. While I understand the first two factors, I am not clear on the third. The standardized outdoor conditions are apparently temperatures set for a specific location to calculate funding eligibility. For our location, this value is -14 degrees Celsius (7°F). With this value, we would not qualify for funding. If the value were -13 degrees Celsius (9°F), we would qualify. Could someone please explain this to me?

You can try using the annual performance factor calculators provided by the Heat Pump Association to experiment with different values based on various parameters. The lower the temperature, the less efficient the heat pump becomes. I’m using -7°C (19°F) as a reference—that makes calculations straightforward (though I do not intend to apply for BAFA funding).
