Hello

Just wanted to give a quick update on how things turned out for us. We built solid, underground insulation, controlled residential ventilation with heat recovery, and gas condensing boiler, NO solar. Primary energy demand is about 48 kwh, which corresponds to Kfw55. However, we financed without a KFW loan.

Conclusion: It works without solar thermal.

Regards
