Waste Oil Burners, Heaters and Boilers

WASTE (used) OIL BOILERS (water heaters)

Omni Waste (Used) Oil Boilers (Water Heaters)

We offer high efficiency, cast iron waste oil boilers that can burn a wide range of fuels (waste oil). To name a few applications: low pressure hot water heating, in floor heating, air, and domestic hot water, industrial hot water needs. Pared with cast iron "Scotch" marine design boiler made by Viessmann (world largest boilers manufacturer), Omni waste oil burning technology delivers unparalleled performance! Boilers are manufactured in Germany, and sections are assembled there as well. Extremely durable and highly efficient "Scotch" marine design principle has been proven in decades of use in large commercial and industrial heating systems.

Just as the waste (used) oil heaters we offer, the boilers we sell are utilizing long passes for hot gases (result of burning) inside heat exchanger (3 passes) maximizing the heat output and delivering 84% of efficiency.

Servicing waste (used) oil boilers we offer is also just as easy as the heaters we provide to our customers. The swing out door on the front and the rear cleanout ports allow easy access for service and cleaning when needed to all of the boilers' heat transfer surfaces and inside of the combustion chamber. For other boiler makes it requires hours of disassembly. All service and cleaning of Omni boilers we sell can be completed literally in minutes. It all amounts in reduced down times and creates additional savings.
