Waste Oil Boilers
Hydronic heat and domestic hot water from the oil you already have. Three EnergyLogic models from 200,000 to 500,000 BTU with wet-floor-based heat exchanger design.
Built-in features, every model
Every EnergyLogic boiler runs a precision fuel-meter pump, is UL listed, and uses a wet-floor-based heat exchanger design with an analog hour meter and a single-wall 250-gallon fuel tank (double-wall available).
Approved Fuels
Optional: Various size fuel tanks · double-wall tank
Find the boiler sized to your load
Full specifications for every EnergyLogic waste oil boiler. Our team will match BTU output, hot-water demand and boiler capacity to your facility.
Hot water working as hard as your shop
Where a furnace delivers warm air, a boiler delivers hydronic heat — hot water for in-floor radiant systems, baseboards and process loads, plus on-demand domestic hot water for wash bays and cleanup.
If your facility runs radiant floor heat, needs constant hot water, or both — an EnergyLogic boiler turns every drained pan of used oil into water at up to 230°F.
Everything a waste oil boiler can heat
Hydronic heat is the most versatile way to put your used oil to work. A single EnergyLogic boiler can run several loads at once — quietly, cleanly and for free.
In-Floor Radiant
Even, draft-free warmth across the whole slab — ideal for shops, garages and warehouses where comfort and clean air matter.
Domestic Hot Water
On-demand hot water for wash bays, sinks and break rooms — up to 8 gal/min at a 100°F rise on the EL-500B.
Pressure-Washer Feed
Pre-heat the water feeding your hot pressure washers and parts washers — faster cleaning, lower energy bills.
Snow & Ice Melt
Keep entrances, ramps and aprons clear all winter with heated glycol loops — no salt, no shovelling, no slips.
Process & Equipment Heat
Feed heat exchangers, dryers, tanks and other process loads that would otherwise burn purchased fuel.
Multiple Zones at Once
Run radiant, hot water and a unit heater off one boiler — zone it room-by-room to match how you actually use the building.
Free fuel that pays you back
The oil is already in your drain pans. Instead of paying a hauler to take it away, a waste oil boiler turns it into water at up to 230°F — heating your building, your wash water and your process loads on fuel that costs you nothing.
For shops generating their own used oil, the system typically pays for itself in a single heating season or two — then keeps saving, year after year, on every litre you no longer buy or pay to remove.
