The Heating System

The Heating System:
A central heating system consists of five main components, each of which can malfunction or fail. There is always your local professional plumber that will be able to help when things go wrong. Always keep his number handy.

The Boiler:
The boiler heats the system (and may also provide domestic hot water). It contains a number of parts that will need regular maintenance and eventual replacement and this is a job for a professional. Annual servicing will keep the boiler in good order. London Power Flush professionals are qualified to work on all heating systems.

The Pump:
The pump circulates heated water around the system. It can become jammed or noisy in operation, or may simply fail altogether. Regular operation and cleaning will help to prevent problems, but replacement is usually quite straightforward.

The Radiators:
The radiators transmit heat to individual rooms. They sometimes develop pinhole leaks due to corrosion, and may trap, gas or sludge (byproduct of corrosion), all of which can cause uneven heating or banging noises when in use. The use of a corrosion inhibitor or leak sealer will help to prevent or cure these problems. London Power Flushing tradesmen can repair and balance radiators.

The Header Tank:
The header tank (also known as the feed and expansion tank) tops up any water lost from the heating system through leaks or evaporation. The tank itself may also develop a leak and need replacing. The ball valve that refills it may jam through lack of use, causing an overflow or allowing it to be drawn into the radiators and pump. A ball valve can be repaired or replaced.

The Controls:
The controls operating the heating system include a programmer, thermostats and motorised valves. Faulty wiring can lead to malfunction, and mechanical failure may be remedied through servicing or replacement of the faulty control.
