Steibel Eltron LWZ 504 in new construction

Hello,

unfortunately I am too far away. However, I can reassure you, the system itself is very quiet. We have installed a better soundproof door in our utility room and now hear nothing from the heating anymore. By the way, the photovoltaic inverter is louder than the heating.

If you have any questions, feel free to contact me; and please don't forget to apply for the subsidy for the LWZ 504. After all, you get 2000€ for it.

Best regards

One more question about the subsidy:
At Bafa they told me that I have to have an annual performance factor of 4.5 to get the subsidy.
As far as I can see at first glance, the system does not achieve that?

How do you know that?

Heating installer has calculated and arrives at an annual performance factor of 4.15

Did he do that with one of the heat pump calculators on the internet? They always showed similar results. I have the figures from Tecalor/SE myself. And with that, I received the subsidy. Has your builder ever installed the system before? It doesn’t sound like it. It is important that the person installing it already has some experience with it.

No, he has not yet installed this system explicitly. That’s why they are also in close contact with SE. The good thing is that they are installing the system in another building this week. So at least I’m not the first. They have now also inquired again with SE regarding the annual performance factor. Yesterday we laid the first row of bricks. When I think about the "mistakes" I have already prevented so far, I get scared and anxious about what is still to come. -_-

It always depends on the design and on the location of the system! We did not receive the funding.
