 Output range up to 35kW / 119,420 BTU’s

Small waste oil heater – Experience gained over many decades makes the Kroll multi/waste oil heater a reliable, cost effective and an environmentally friendly heating product. Our W401 heater is a manual ignition, or vaporising waste oil heater- which are lower cost, simple to use and maintain and very robust.

Although these heaters are classed as a multi or universal oil heater it is important to know that petro-chemical based oils or lubricants, solvents, transformer oil, thinners and any oil above grade S.A.E. 80 should not be used in these drip waste oil heaters.

This heating technology can permit the end user to recover the initial investment costs sometimes within one heating season due to the savings made from using our universal oil heater instead of a more expensive fuel oil heater. These heaters are manufactured using the latest technology and have a 12-month warranty on them, which ensures complete customer satisfaction

The high efficiency of the Kroll W401 range of universal oil heaters is achieved by an integral, large heat exchanger, through which all the combustion gases have to pass before entering the flue system. Then a high capacity axial fan draws the air from within the workshop, garage or building over the heat exchanger and combustion chamber and expels this now heated warm air into the area, providing a constant recycling of this warm air.
