@raiph  I would be interested to hear how you are finding Havenwise. Can you see how it's settings are different from how Water law performed before and whether your electricity consumption has dropped since you joined?

Good idea 🙂

Manufacturer: Midea

Model:10kW R32 Monobloc

Arrangement: Bivalent and with a Heat Saviour. Navien combi on the CH side (not via the Heat Saviour) as backup or when it's very cold and heat pump on the primary side of the Heat Saviour with glycol.

Area of Country: Glos

Home Type: House

Size: Square Metres: 200

Insulation Level: 5

Heat Loss Calculation: Mine via Heatpunk is ~12kW at ODT ~-5. I can't remember what the installer's was but it's not relevant.

Type of Controller: Modulating, Thermostats, TRV's etc. Modulating, experimenting with smart TRVs.

Type of Control: Weather Compensation

System Type: Radiators

Total Output of Heat Emitters: Depends on flow temp....

Buffer Tank or Low Loss Header: Heat Saviour - heat exchanger and small volumiser

Secondary Pumps: 1

Solar PV System: Not yet

Power Diverter: Not yet
