The house is currently heated centrally with a gas heater and radiators in the rooms with individual thermostats. The air conditioning units can be set individually to heating in the bedrooms.
The reaction time to heat the whole house from scratch is one or two days.
The heating system will be supported with a heat pump and solar energy but the full setup is not yet done. Heating of the house can cost 100€ in gas per day so it might be useful to consider a jumper and set the thermostat (Honeywell in close to the internal garage door) to 19 degrees.
Cooling is currently done via three split air conditioning units which can also be used for heating when needed. There is an ongoing project to install additional air conditioning units in the apartment, the kitchen, and the AC bedroom from a central 18 kW heat pump both for heating and cooling.
There are some manuals for the system: Gas heater, Mitsubishi Air conditioning unit in J and D bedrooms, Argo Air conditioning unit T bedroom.
