Oil-fired boilers are an efficient solution for domestic hot water and heating. An oil-fired boiler functions similarly to a gas boiler because it uses boiling oil to produce hot water, which is then delivered to your home’s hot-water taps. Home heating oil boilers distribute heat in one of three ways throughout the home. Heat can be distributed through vents as steam through radiators, as warm air, or as hot water through baseboards.
When the thermostat detects that the temperature in a room has dropped below the required heat setting, it sends an alert to the oil-fired heating system to begin heating. The heated oil is transferred from the tank to the burner through a pump, where it condenses into a mist mixed with air. The mix of fuel and air enters the burner and ignites in the combustion chamber, beginning to heat the water.
The primary distinction between the gas and the oil boiler is how the fuel is stored in the appliances. A gas boiler does not require gas storage because it is linked to the mains, ensuring a constant fuel supply. On the other hand, an oil boiler requires a tank to hold the oil until it is needed.
