The system is including radiator heating circuits and hot water tank powered by a Parkray Chevin 111 coal boiler. We replace the old boiler with a PFP160 Glass Klover pellet boiler stove with the aid of Boiler Upgrade Scheme.
To avoid draft in the room around stove we installed air supply for stove directly from outside air.
A radio thermostat will control the room temperature. The Klover stove also has a special feature to prevent from overheating.
There is not any ready made controller for this specific system layout. This is why we use again our universal controller.
This controller has spare inputs and output ready to control a solar thermal system in the future.
