Having an oil fired boiler serviced regularly can keep it operating at its most efficient. This reduces fuel bills and saves money on costly call out fees for unexpected breakdowns, it is recommended that oil fired appliances and equipment are serviced at least once a year.

There are many reasons why the efficiency of an oil fired boiler could be reduced. Here are a few:

Excessive smoke and partially burnt fuel deposits soot on the heat exchanger which restricts the amount of heat which the heat exchanger can transfer into the water. The cleaner the heat exchanger the more efficient the boiler will be.

Oil Nozzles will wear. They regulate how much oil is used and if it is not regularly replaced it could cause “sooting up” of the heat exchanger, and so reduce heat transfer.

Photocells can glaze over with soot. Boilers switching on and off frequently will be less efficient than when running for longer periods.

Electrodes can wear and carbon up, causing inefficiency and increasing fuel cost.
