Hello everyone, I am looking for an air-to-water heat pump with around 12 kW heating capacity that is also eligible for funding. I am confused about the LWDV 91-1/3 HDV 12 and HSDV 12 models from Alpha Innotec. Do they actually have a 12 kW heating capacity or not? They are basically the same as Novelan, and there is no clear information there either.
Are there any professionals in the forum who are familiar with this?
Good luck

I took the value from the energy calculation.

freisinger25 Jan 2020 09:00Thanks to the heating load calculation tool, I finally have a basis to work from, even if it’s not 100% accurate. Now, the heating technician shared his calculation basis with me after I sent him mine, and as it turns out, he used different parameters. Let’s wait and see how his new calculation turns out using my values. But it will probably be similar to mine. With the heat pump mentioned above, we will manage without any problems.
Thanks for recommending the tool.
