Riello is a global leader in oil and gas burners, and its Riello 40 F-Series blue-flame burners are a popular, reliable choice on Long Island for clean, quiet oil heat. The pre-assembled design and hinged housing make Riello burners fast to service, and they hold their settings well once dialed in.
Riello oil burner highlights:
Riello burners come in a range of firing rates and price points. Here is roughly what an oil burner replacement runs, using current national averages.
| Item | Typical cost (U.S. average) |
|---|---|
| Oil burner (the unit itself) | $1,200 - $4,000 |
| Installation labor | $1,000 - $3,000 |
Per Angi and HomeGuide (2026). Replacing just the burner costs far less than a whole new oil furnace or boiler (about $2,500 to $10,000). A straightforward burner swap on an existing appliance usually lands toward the lower end; your exact price depends on the burner model and your system.

Every oil burner we install is matched to your boiler, furnace, or water heater and dialed in with a full combustion analysis, so it burns clean and efficient from day one. Our technicians set the correct nozzle and firing rate, gap the electrodes, adjust air and draft, and verify CO2, oxygen, smoke, and stack temperature before we leave.
Whether you are upgrading an old burner or installing one with a new appliance, we make sure your Riello burner is sized and set to manufacturer spec. See our full oil burner service or browse all oil burner brands.
If your burner is locking out, sooting, smoking, smelling of oil, or running noisy, we diagnose and repair it quickly, with 24/7 emergency no-heat service across Suffolk and Nassau County. We carry or quickly source common Riello parts, so most repairs are finished in a single visit.
An annual tune-up, a fresh nozzle and filter plus a full combustion test, is the single best thing you can do for oil-heat efficiency. It keeps the burner clean, safe, and using as little oil as possible.
If you still have an older conventional (non flame-retention) burner, upgrading to a modern flame-retention Riello burner can noticeably cut your oil use and run cleaner and quieter. We will tell you honestly whether a tune-up, a repair, or a new burner is the smart move.
When a new burner is the answer, we match it to your appliance's firing rate, install it, and prove the result with a combustion analysis, all with a free estimate up front. Heating with oil a different way? See our boiler brands and furnace brands.
