Heating oil is a fuel choice for heating and furnaces systems in older houses and in places where there is no natural gas service. According to the American Department of Energy, a typical oil-burning central warming unit is more efficient than a minimally efficient gas-run system. Unlike electricity or natural gas, heating oil is not supplied directly to the home via a community network of pipes and lines. Oil must be ordered and delivered by a vendor. When you have your oil tank packed, it is possible that you will require to prime your burner oil before you glow your pilot. Priming pushes surplus air from the system and stops air force from building up in the tank.

  3. Locate an empty jar or can in face of the bleeder control device and turn the energy to the burner oil on. Oil will start to split from the bleeder as air is pushed from the pump and supply line. When the oil starts flowing gradually, stay with the oil grip in face of the bleeder, turn the bleeder off and make stronger the hex nut on the bleeder.
  4. Put the oil grip can aside and wait 2 to 3 minutes. This will permit the system that lights the burner to rightly recycle itself.
  5. Press the energy button on the burner of oil again to glow the furnace.
