Hello. Our heating system deviates from the application. The reason is that according to the installer, although the old heating system is still subsidized, there would be more and more problems with it.
We previously had the Aerotop Slit 07 M-RX and now the Aerotop Split 07 M-R. The only difference I see is that the x version runs on 240 volts and the new one on 400 volts. Are there any other differences, see attachments. What are the advantages and disadvantages of 240/400 volts?
My actual question is how I should proceed regarding BAFA. The funding approval from BAFA is available. Both heating systems are on the subsidy list. The plumber has no idea and doesn’t care / is not concerned.
A hydraulic balancing was recently done but I do not have it yet. A power meter, what is meant by that? Attached is a picture of our box. I bought a heat meter and the plumber installed it. He now wants to install a second one. But can’t the consumption be calculated by reconciling the electricity meter and the heat meter? The upper meter must be for consumption calculation, right? A photovoltaic system is also present (just for info).
Who takes care of adapting the heat pump to the building? Is there proof of this?
