OMNI by EconoHeat

OWB series boilers are three pass Scotch Marine design with fully water backed transfer
surfaces. Boilers are designed for use in forced hot water heating systems. Heating is supplied
by a Waste Oil Burner that burns all petroleum products any weight combination up to SAE
90W as well as fuel oils. Boiler–Burner units operate with no less than 0.01WC or greater over fire
and may be vented using a conventional chimney.
