I've got a Mitsubishi Ecodan 6KW with a 170 litre slimline pre-plumbed unit with an FTC7.

My turn, this describes the future installation, only the heat pump and UFH are operational at the moment.

 

Manufacturer: LG

Model: HM163HF.UB60

Type: ASHP 16kW Monobloc R290

Arrangement: Low temp HP + wood boiler backup

Area of Country: Lyon, France

Home Type: House

Size: Square Metres: 380

Insulation Level: R=5.7 walls, R=7 roof

Heat Loss Calculation: 8-12kW @ Amb. Temp, of: -7C

Type of Controller: Modulating

Type of Control: Weather Compensation, Flow Temperature, Room Temperature

System Type: UFH, Radiant ceilings, Fan coils for cooling

Total Output of Heat Emitters: Way more than necessary. Concrete slabs alone can store at least 30kW and release through the day.

Buffer Tank or Low Loss Header: 1000l tank with instant DHW coil used as Buffer on wood boiler, heat pump will heat it for DHW also. For regular heating, heat pump direct to slabs & radiant ceilings.

Secondary Pumps: 2 most likely

Solar PV System: 12kWp

Power Diverter: Yes for EV charging, soon for heat pump

Battery System: 20kWh
