Technology and Safety for Used-Oil Heaters and Boilers

Three Simple Rules for Used Oil Heaters

Used Oil Heater
Constant improvements in the design of used-oil heaters and boilers in the last decade have increased their efficiencies and reduced emissions. Studies demonstrated that used-oil heaters and boilers are economically and environmentally sound investments.
UOMA members have their heater and boiler units tested for safety by independent laboratories such as Underwriters’ Laboratories (UL) and the Canadian Standards Association (CSA), and each used-oil heater and boiler comes with a safety rating. Automatic fuel cutoffs and other safety features, in combination with servicing and operational guidelines, ensure that all used-oil heaters and boilers function safely, cleanly and efficiently.

Three Simple Rules for Used Oil Heaters

The U.S. EPA established simple guidelines for the environmentally sound, economically beneficial practice of recycling used oil on-site as a fuel in a used-oil heater or boiler:


The heater must burn used oil generated on-site or collected from do-it-yourselfers


The heater must be vented to the outside air


The capacity of the heater cannot exceed 500,000 Btu/hour
