How does a oil furnace operate?
When the oil heats, it moves from the tank to the burner through a pump, and it becomes a warm mist mixed with the air. The fuel and air mix go into the burner, where it creates flames in the combustion chamber. The oil heats the air or water that heats your home, depending on the type of heating system you have.
How does old oil furnace work?
When activated, the oil furnace uses a fuel pump to draw oil from a reserve tank through a filter and into the burner chamber. There, the oil is converted into a mist that is sprayed onto the burner. The air that was pulled from the home and into the furnace passes over the chamber and heats up as well.
How does an oil boiler heating system work?
An oil boiler works in a very similar way to a gas boiler. The fuel, in this case oil, is ignited in the combustion chamber and a heat exchanger warms up cold water, either from the mains in a combi system or from a cold water tank in a conventional system. Oil is a more efficient fuel than gas.
