Features of our Waste Oil Heater / Multi Oil Heater


The burner is equipped with a photocell that continuously monitors the flame.

In case of ignition failure or poor combustion, lack of a flame or partly blocked nozzle, the photocell stops the burner.


This multifunctional thermostat ensures that the main fan only starts after the combustion chamber has been sufficiently heated. Therefore, there is no cold air blown before the heater has warmed up.


Electrical overload is protected by a trip system for both the main fan and the burner.

Heating overload is protected by a limit thermostat built into the heater control thermostat. This has an automatic reset.

Any obstruction of the main fan or its air stream is secured by a manually reset overload protection.


In summertime the heater can be used for ventilation only
