Oil Heat Service

Oil-fired furnaces and boilers should be cleaned and tuned annually. The technician should have test equipment and should measure SSE, CO, draft, and all other parameters that are relevant to the seasonal efficiency of a furnace or boiler. A tune-up, performed by a qualified technician, will usually save 5% to 20% of the heating fuel, depending on the heater’s existing condition and the technician’s skill.

Older oil heating units have a maximum SSE of around 80%, which can only be improved significantly by installing a more efficient burner.

During the professional service call, the heating technician should test and inspect the oil-heating system for safety and efficiency of combustion by the following actions.

Check the heat exchanger for cracks, corrosion, and soot.

  • Test the flame sensor.

  • Set heat anticipator to control the circuit current (amps).Adjust barometric damper to .02 IWC over-fire draft.
  • Perform initial combustion test.
  • Test for CO and remove the causes, if found.
  • Clean the oil strainer.
  • Clean the burner’s blower, blast tube, and electrodes.
  • Replace nozzle, resize it if appropriate.
  • Replace the oil filter.
  • Set the gap between electrodes at the correct distance.
  • Repair oil leaks.
  • Test oil-pump pressure.
  • Adjust spinner and shutter for minimum smoke.
  • Perform final combustion test

  1. It’s interesting to know that having our equipment tuned-up by a professional could save up to 20% of fuel. I used to think that calling a technician should only happen when the boilers are broken. Thanks for helping me understand more about the importance of inspecting the heating system.

  2. Thanks for mentioning how a good technician should inspect carefully your heating oil system. It is important to remember that doing some research can help you know what the best type of oil your appliance uses. Personally, I would also want to have the same company that delivers my heating oil to help with my appliances to make sure they are compatible.

  3. Thanks for your comment about how you should hire a professional contractor or electrician to deal with all our heat needs. I like how you said that they can test it for you. My husband and I are considering contractors to fix our oil burner.
