The EL 200H Waste Oil Heater has all the perks of the EL 140H and more! Constructed to last decades, not years. 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! Heats up to 5,000 square feet approximately four to eight service bays with 200,000 BTU per hour.
