If you have fuel oil delivered to your home, then it can be used for either space heating or water heating. And sometimes it can also be used for swimming pool heating.

If you use fuel oil for heating your home, then you have a Oil Furnace or Boiler. The difference between an Oil Furnace and an Oil Boiler is that an Oil Furnace burns oil to heat air for your home heating system, where an Oil Boiler burns oil to heat water (or steam) for your home heating system.

An Oil Furnace or Boiler is different than a Water Heater (oil), which heats just the water that is used in your plumbing for your sinks, baths, and showers.

Shown in the 'Routine Care' section are the recommended routine maintenance tasks for your oil furnace or boiler. The 'Q & A' section shows answers to common questions. And the 'Articles' section provides helpful articles about your oil furnace or boiler.
