Heat pump design review please: 5 kW Vaillant aroTHERM Plus heat pump
@ragtime27 some rooms in our house only have one place where a radiator could easily go and the (possibly) larger radiator for 45C might mean putting it elsewhere. In our smallest bedroom that would mean a clash between the bed and the door. It depends on the detailed shape of your rooms.
2kW + Growatt & 4kW +Sunnyboy PV on south-facing roof Solar thermal. 9.5kWh Givenergy battery with AC3. MVHR. Vaillant 7kW ASHP (very pleased with SCOP >4) open system operating on WC
