The small bedroom and the guest toilet downstairs are equipped with an electric radiator with its own thermostat. Please use these consciously acknowledging that electric heating is expensive. 

The bathroom has an electric towel radiator connected to a timed thermostat to warm the bathroom in the mornings and evenings. Further, there is an infrared heater in the bathroom next to the toilet (the big white panel). There is a turn-dial timer switch for switching this on the wall on the far side of the toilet. Recommendation: Turn it to 30 minutes when entering the bathroom for your shower.
