Heating system provider

I plan to build a small single-family house. I am currently looking for a provider of a complete system for self-assembly. The living area is about 130 m² and I want to combine a heat pump, water-carrying fireplace, and solar thermal system. Can someone give me a tip on who offers something like this??? We have already been to [ZWS].

.....The living area is approximately 130 m² and I want to combine a heat pump, a water-bearing fireplace, and solar thermal.

Self-construction is usually chosen for cost or economic reasons. In this regard, the ideas do not quite match. How far along is the basic investigation? Are all necessary calculations available for this?

Best regards

If you mean the calculation Oozyder heating load, I don’t have one. At our place, colleagues from Zws and heat were here and all offered me a 9kw heat pump. Kfw 70 house with 130sqm. Can you help me?
