eligible greywater storage ErP Class A

Hello everyone,

Currently, my heating engineer is offering a Novelan brine heat pump. In order for it to be eligible for funding under the 10000 Houses Program (Bavaria), the storage tank must meet the following condition:
- Thermal storage with at least 30 l/kWth effective volume
- Storage insulation with standby loss S < 8.5 + 4.25·V0.4 or U-value ≤ 0.20 W/m²K
- The central feature of the heat storage tank for funding is the standby loss of the heat storage tank. Within the framework of the 10,000 Houses Program, heat storage tanks with energy efficiency class A or better are subsidized.

Question for you: are there storage tanks with the above specifications that can be combined with a Novelan SIC 12.3 and have about 400l volume?

My heating engineer can't find any.

Thanks in advance.

There are several.
Take a look at the manufacturer OEG or Thermic Energy.

We sourced our 200L storage tank for the 10,000 houses program back then from there.

I quickly picked out 2 for you (with energy efficiency class A or A+):

Alternatively, there is a good overview at C.A.R.M.E.N. EV:
Google "Marktübersicht Wärmespeicher Carmen-ev" and open the PDF there.

However, all of these are "relatively" expensive.

Thank you very much. I will get informed right away.
