Do I need to filter waste oil before I burn it?

You should always use all equipment subject to the guidelines given in the operating manual. In general you do not need to pre-filter waste oil before it enters the heater. Our vaporising waste oil heaters series have basic wire mesh filters to protect the heaters’ mechanical parts from larger debris. The burners with the atomising waste oil heaters are typically supplied with a cleanable inline suction filter. This is designed to remove sediment and particles that could block the burner nozzle.

What is the fuel consumption of the heaters?

Fuel consumption ranges from 2 litres per hour to over 20 litres for and is stated in the specifications for all our waste oil heaters and burners. As well as the size of the building, it is important to consider the volume of fuel available too in selecting your heater. Please don’t forget the heaters are more accurately termed “universal oil heaters” than the more popularly termed “waste oil heaters” as they will burn a full range of oil based fuels including kerosene / paraffin or diesel.

Where can I compare the performance of the models available?

All the key information is shown in the Products area of the website. 

Is it legal to burn waste oil in England & Wales?

Since March 2016 tighter restrictions have been placed on the permits required, you can read more here.

Is it legal to burn waste oil in N. Ireland?

The law has recently changed (May ’12) meaning it is no longer legal to burn waste oil and that SWOB’s used to burn waste oil will be subject to the Waste Incineration Directive. You can however continue to use heaters to burn PFO (Processed Fuel Oils) or other heating oils. Further information is available here.

Is it legal to burn waste oil in Scotland?

No. The Scottish Government’s interpretation and implementation of the EU waste incineration directive is different.

For further details please follow the link to view the Waste Incineration (Scotland) Regulations 2003: Practical Guidance: Edition 2. Equipment like the waste oil burners and waste oil burners shown on this site fall within their broader definition of a “technical unit” and “waste vegetable oils” and “waste oils, including recovered fuel oil” are listed as types of waste.

Please note, the universal waste oil burners and universal waste oil heaters shown on this site are perfectly legal to buy and use as a cost effective means of heating with other fuels such as heating oil, fresh vegetable oil (SVO) or diesel.

Are waste oil heaters banned?

It is important to note that universal waste oil heaters and burners such as those offered here are not banned as they can heat effectively using other fuels including heating oils.

Which model of waste oil heater do I need?

Where you require an installed universal waste oil heater, you will need to consider the heat required. This can be worked out from the volume of air to be heated and the insulation level of the building space. The calculator on our home page using these values along with a temperature change value of 20 degrees C (e.g. -4 C to +16 C) to calculate the kW output you will need from your heater.

There are then vaporising and atomising heaters to choose from. The vaporising heaters are most cost effective to buy and are easier to install (requiring only 240v power supply). The atomising heaters are more sophisticated and can be controlled automatically with thermostats. They will also tend to burn more efficiently and require less cleaning but will need three phase power supply (400v) and compressed air supply to operate the burner.

Can I fit a waste oil burner to an existing heater?

It is possible to retro-fit a waste oil burner onto an existing heater or boiler but you will need to consider the combustion chamber dimensions and the position of the mounting points. It is also necessary to ensure that the burner can be mounted securely and will seal properly. Further information is available on request.

Why are waste oil burners more expensive than heating oil burners?

Universal waste oil burners need to effectively burn a wide range of fuels. Different types of waste oil will have different flash points (the point at which the fuel ignites) and different viscosities. The presence of particle, moisture and so on also make the fuel more difficult to burn consistently. In many cases the viscosity of waste oil will be considerably higher than that of heating oil. There is also a greater need for filtration. To overcome the challenges, combustion is achieved through compressed air driven delivery to atomise the fuel through a special nozzle and by a variable level of preheat to decrease the viscosity of the waste oil to a level where it will flow reliably through the burner.

Is it environmentally friendly to burn waste oil?

Waste oil is energy rich and safe to burn. From a greenhouse gas emissions perspective, burning waste oil on site is the most effective solution. It saves the emissions of the truck coming to collect it, the energy cost of recycling it and then the further impact of packaging and redistribution. As most waste oil is eventually burned anyway (for power production in generator furnaces) the net impact of burning waste oil on site is generally regarded as positive.

It is important to service and maintain your universal waste oil burner or heater as specified in manufacturers guidelines. If you do this and use appropriate fuel sources, modern waste oil heaters and burners will achieve clean and efficient smoke-free combustion. Care should be taken in disposing of ash residue as specified in the LAPPC permit.

How much money will I save by burning waste oil?

The saving will equal the cost of your gas, oil or electric heating minus the cost of your LAPPC permit. If you currently pay for waste oil collection you can add on a saving there too. In practice this means a return on investment for the money paid for the heater can be less than a single season and the more energy costs rise, the more you will save.

Which types of waste oil can I burn in my heater or burner?

These universal waste oil heaters and burners will effectively burn a wide variety of fuels including conventional 28 sec or 35 sec kerosene or heating oil. The heaters will run successfully on waste mechanical oil (engine, gear, hydraulic etc), used cooking oil (WVO), straight vegetable oil (SVO) and heating oil. Any oils with a maximum kinematic viscosity below 6.00mm2 per second at a temperature of 20 degrees C and maximum ignition temperature not lower than 40 degrees C and density above 0.94g/cm3 will burn cleanly and safely.
