Working principle

The stationary used heater (vegetable or
biodiesel) is equipped with three electric
motors.
The first electric motor drives a fuel pump,
which pumps up the fuel from the fuel tank.
The second electric motor drives the
combustion air fan, which blows the
combustion air into the combustion chamber.
The third electric motor drives the hot air fan,
which extracts the hot air around the
combustion chamber. The hot air is blown
into the space to be heated.
Vegetable oil or biodiesel is poured manually
on a burner dish, which is ignited with a
burning paper pellet. As soon as the burner
dish is at the right temperature (position 2,
automatic) the pump thermostat activates the
fuel pump; the control light flashes on. The
fuel pump pumps the vegetable oil or
biodiesel onto the burner dish. The vegetable
oil or biodiesel evaporates due to the
temperature of the burner dish. The gas
vapour burns. The fan thermostat switches
on the motor of the hot air fan, which causes
the hot air to be blown from the heater into
the space to be heated.
The pump thermostat switches off the fuel
pump when a failure causes the heater to
overheat.
The fuel pump is switched off when the
heater is switched off.
The hot air fan runs until the fan thermostat
switches off the fan when it has sufficiently
cooled down.
The fuel supply has an overflow that ensures
that the vegetable oil or biodiesel flows back
into the fuel tank when the fuel pipe is
blocked.
The overflow protection switches off the fuel
pump when the burner dish overflows.
