Missing An Annual Service Can Affect Your Safety And Cost You More

wasting moneyMissing an annual service does more than costing you money in the long term. There is also safety to consider. When a qualified engineer performs a correctly done service they can check on many things…

Excessive smoke and partially burnt fuel can deposit itself in the heat exchanger in the form of soot, restricting the transfer of heat to the water in the heating system. A clean heat exchanger will transfer more heat giving you better efficiency. According to OFTEC, 3 mm of soot build up can bring about a drop of 8 % in efficiency.

Photocells, which detect the light in the heat exchanger(the flame) can glaze over or get specks of dust/soot on them, this can cause the boiler to shut down. Boilers that frequently switch on and off are less efficient than those that run for a longer periods.

Electrodes create the spark that lights the oil/air mix inside your boiler, over time these can become worn and attract soot, if in poor condition, these may not produce the ‘correct’ spark causing the boiler to lock out. Also, if these aren’t positioned correctly, they can cause flame infringement further still lessening the efficiency of the boiler.

Oil nozzles are replaced every 12 months for a reason, they are a consumable that wear over time affecting fuel combustion, they could cause ‘sooting up’ of the heat exchanger due to too much fuel passing through.

Baffle plates, if not cleaned regularly can attract deposits which make it impossible to remove and clean them,again causing a loss in efficiency.

The service allows the engineer the opportunity to inspect the boiler and tank and make it as efficient and safe as possible.
