The EL 350H Waste Oil Heater has all the benefits of the EL 200H and the 140H and more! Heats up to 9,000 square feet with 350,000 BTU per hour. With an elevated fuel pack, the pump can be mounted at the fuel source—instead of on top of the tank—so the pump is flooded with used oil, not air! Fuel pick up is six inches above the bottom of the tank, above water and sludge, ensuring only used oil is sent to the furnace. Comes with an easy spin-on stainless mesh filter for convenience.
