KWOB Multi/Waste Oil Boilers
From 27kW to 1,275kW Output
Waste oil boilers deliver an efficient way to recycle waste oils as a free fuel source to generate heat and hot water, which can be used to heat garages, workshops, warehouses, greenhouses to name but a few, within the broad range of applications it can be used for. Our German made waste oil boilers are designed for the unique demands of providing water heating systems run on waste engine oils, hydraulic oil, vegetable oils, bio-diesel and a range of other fuels. Convert all these free or low cost fuels into clean, usable heat and virtually eliminate your fuel costs!
At a time of rising fuel costs, the Kroll universal/waste oil boiler, which can burn nearly all vegetable, animal, conventional and waste oil, will save you money and provides you with flexibility in choosing your preferred fuel source.
The Kroll series of waste oil boilers are designed for perfect compatibility with Kroll waste oil burners, providing a complete and proven solution. These waste oil boilers are made in the EU and exported worldwide. They combine exceptional prices with excellent quality for unbeatable value.
In more recent times we have seen a large increase of people using vegetable oils as a fuel, this is a very green option as its renewable and also is CO2 neutral. Our burner was one of the first, of the very few to gain the DIN standard for use on rapeseed oil, which is used extensively as fuel in countries such as Denmark and Sweden due to the high relative prices of energy within those regions
Did you know that you could significantly reduce or even eliminate your heating costs by utilizing waste oil boilers or heaters for your heating needs? Waste oil boilers and heaters fuelled with used oils such as used vegetable oils, recycled oil, used motor oils and hydraulic oils –
What can the Kroll Multi / Waste Oil Burner use as a fuel-
- 35/28 second Heating Oil/Diesel
- Processed Fuel Oil ( PFO )
- Rapeseed Oil
- Linseed Oil
- Certain Vegetable Oils
- Used Engine Oil (subject to licensing control)
- Hydraulic Oil
- Bio Diesel
The Boiler, is a steel Pressurised steel boiler for operation of water temperatures above 50C, and benefits from the following features –
Reversed flame combustion chamber for high efficiency, efficient combustion, low emissions and lower flue gas temperature
Highly resistant to condensate thanks to:
– Furnace misalignment against the outer shell
– Patented fin effect on the welding seams of pipes onto the rear tube plate
• Anti-condensing helicoidal turbolators
•Fully insulated design prevents heat loss, due to the extensive insulation (60 mm) of rock wool surrounding the boiler body and the ceramic fibre insulation on the door
• Adjustable door with double opening (left or right)-with easy access through the front door to all parts of the boiler chamber for quick, easy cleaning and ash removal
• Separate control panel with simple and clear information and controls
• Maximum working pressure: 6 bar; it is possible, under specific request, to provide a MWP of 7 – 8 – 9 or 10 bar

Waste Oil Boiler , now with the option of a built in compressor up to 116kW, the range extend to 1,110kW ( external air source required after 116kW )
Here at Flexiheat , we are always moving our product development forward , and due to many requests , we now have a waste oil boiler and burner combination , that has a built in compressor , thus eliminating the need for an external air source. This means that burner only produces the air that is required when the burner is in use, this results in large running cost reductions, as you don’t need a compressor running 24 hrs / 7 days a week to supply the air to the waste / multi oil burner attached to the boiler. This option is available on our waste oil boiler packages with an output of up to 116 kW / 395,792 BTU’s . At present after this kW output then an external air supply is still required . These Flexiheat Multi Oil Boiler Packages are now designated the “FMOB” range , and if the unit has a “C” after the model number , then this means that the burner has a built in compressor.The full range of multi/waste oil boiler goes up to 1,100 kW output , but after 116kW output , you do require a compressed air supply , with a 1.5 Bar pressure and the volume of air require varies with regards to the burner output.
