The W401 is our opinion is the best small waste oil burner UK wide. We have just supplied spares to a unit that is 45 years old ! a testament to the quality of this German made unit.
It has been commonly known for years that waste oils, have a calorific value ( or heating energy ) very similar to conventional heating oil. The secret has been to get the oil to burn safely,cleanly, and without any pollution and Kroll has been doing this for years with this unit, meaning that you get as much heat as you require , combined with virtually no running costs. These Kroll waste oil heaters run cleanly and more importantly efficiently on all engine oils , whether it be hydraulic oil,sump oil, gear oil or transmission fluid. You can literally use it as it comes from your transmission or engine from your machinery or vehicle, without the need for any special filtering.
The Kroll W401 small waste oil heater is particularly suitable for heating automotive workshops and garages, warehouses, small greenhouses, etc.They are equipped with a self contained oil tank of 25 litres and are easy to install, being instantly ready for use.
Can be supplied with our without a top mounted Thermo-blower to increase the throw of hot air .A high capacity axial fan draws air from the area over the heat exchanger and combustion chamber and expels the warm air into the building, providing a constant supply of warm air. The unit runs off a 240Volt supply.

Waste Oil Heater Maintenance on the Kroll W401 Heater / Small Waste Oil Heater
Well as the saying goes ” you get nothing for nothing in life “. The only thing you will have to give to any small waste oil heater , that is manual ignition , is a bit of your time. Firstly, this waste oil heater is a basic bit of heating equipment and not “high tech” in any form – by this we mean that you don’t have to be a heating engineer to use or maintain the heater. To start the multi/waste oil heater , you pour a cup of diesel or kerosene into the cast iron burner basin, which sits at the bottom of the heater , and then light it with a match. Then after approximately ten minutes the internal thermostat automatically starts the oil pump and the blower fan . Waste oil then trickles into the burner basin, where it vaporizes into a gas and then is burnt very cleanly and efficiently resulting in the heater giving off no fumes or smoke via the flue pipe exhaust system. Any contaminants in your waste oil such as dirt,carbon or detergents are broken down in the 750 °C temperature of the combustion chamber , leaving a crusty dry ash which accumulates in the burner basin , which we recommend cleaning every day . taking about 5 minutes of your time.The amount of ash you will get will depend on the quality and cleanliness of your waste oil , but for example transmission oils leave almost no ash generally, very thick waste engine oil from oil diesel engines leave more ash . Generally , oils from petrol engines , or a combination of waste oils , gives you plenty of heat and very minimal ash.
What a lot of our customers do , is purchase another burner basin off us , so when they start the unit every morning , they use the clean one , then at a time convenient to themselves, they clean “yesterdays burner basin”, making it ready for use in the heater “tomorrow”.
I think you agree that these 5 minutes a day , is a small price to pay for the advantage of warm air heating with free fuel !
