The central heating system uses two or three heat sources
– an LPG boiler and a 230 volt electrical heating cartridge,
as well as an externally-tted heat exchanger for motor
caravans. The LPG boiler/heating cartridge heats up a
liquid mixture consisting of water (60%) and glycol (40%).
With the aid of a 12-volt circulation pump, which is located
in an expansion vessel, the warm glycol/water mixture is
circulated round the system through pipes and radiators.
The radiators, which are tted along the outer walls, heat
up the air, which rises and warms the walls and furniture.
As the warm air rises, it forms an air-barrier which keeps
the cold away from the windows.
The temperature inside the caravan is controlled by a 12
volt thermostat on the control panel.
