Waste Oil Heating Information


Waste hydraulic, engine, gearbox, etc oils are considered to be hazardous waste, and burning of these in heaters is regulated.

In Scotland and Northern Ireland :- waste oil cannot be used in waste oil burners unless monitored at a cost of approx. £10 000 per year.

In England & Wales :- regulations changed with effect from 6th April 2016. Waste Oil Burners / Heaters (SWOBs) using waste oils as a fuel are now within the scope of Chapter IV of the Industrial Emissions Directive. To burn waste oils as a fuel the relevant permit under Schedule 13A of the Environmental Planning Guidance is required. Cost of application is £3218 with an annual fee of £1384. Additionally, requirements will be placed on emissions monitoring and operational control procedures.

Processed Fuel Oil (PFO) is considered "end of waste" and burning this does not fall within the above regulations. This can be used throughout the UK.

Thermobile waste oil heaters can also legally operate without permits using the following alternative fuels :- 35 sec Heating Oil, Diesel, Processed Fuel Oil (PFO), and Bio Oils including Rapeseed Oil and Linseed Oil, plus certain refined Vegetable Oils.
No adjustment is necessary on the AT range of Waste Oil Burners (manual ignition range).
Simple adjustments to the compressed air supply and the oil pre-heater thermostat is necessary on the SB range of Waste Oil Heaters (automatic ignition range).
