Sound Like Your Heater?
Burner won’t ignite / no flame
Ignition electrodes, transformers, photocells, and control primaries. A heater that won’t light is our most common waste oil call — we diagnose the ignition circuit and get flame back.
Nozzle clogging or dirty burn
Waste oil is hard on nozzles. We clean, rebuild, and replace nozzles and preheaters so the burner atomizes properly and burns clean instead of coking up.
Oil won’t pump or feed
Fuel pumps, oil lines, filters, and preheater blocks that gum up on dirty oil. We rebuild the fuel side so oil flows to the burner at the right temperature and pressure.
Smoking, sooting, or short cycling
Combustion out of tune, dirty heat exchanger, or air-band and draft problems. We clean and re-tune combustion so the unit runs efficiently and passes a clean burn.
Boiler won’t hold temperature / no heat
Aquastats, circulators, zone valves, and heat exchanger issues on oil-fired boilers. We service the heat and hydronic controls to restore steady output.
Lockouts, faults, or dead controls
Primary controls, thermostats, limit switches, and wiring faults that lock the unit out. We troubleshoot the control system safely, in-shop or on-site.
Not on the list? If a waste oil heater or boiler does it, we’ve fixed it. Describe the problem and we’ll take it from there.

WASTE OIL EQUIPMENT REPAIR FAQS
We do. H2O Power Equipment is a factory-authorized EnergyLogic service center with shops in Denver (Commerce City) and Colorado Springs and mobile repair within 300 miles, and we service heaters and boilers of most other makes too.
Usually an ignition problem — worn electrodes, a failed transformer, a dirty photocell, or a primary-control fault — or a clogged nozzle and cold/contaminated oil. We diagnose the ignition and fuel circuits and restore a clean flame.
Combustion out of tune, a clogged nozzle or preheater, or a heat exchanger that needs cleaning. We clean and re-tune so it burns clean and efficient.
Yes — waste oil heaters and boilers are serviced exclusively on-site. Because these units are ceiling-hung or plumbed into your shop, our factory-trained techs come to you rather than bringing equipment in. Our fully stocked mobile trucks cover a 300-mile radius from Denver and Colorado Springs, across Colorado and into southern Wyoming.
Yes. A pre-season tune-up — nozzle, combustion, and fuel-system service — is the best way to make sure it fires on the first cold day instead of failing when you need heat most.
