There are a wide range of different parts which go into making a modern boiler work both safely and efficiently. If a boiler breaks down, spares are readily available. Boiler design and advances in technology mean that it is vital that the correct parts are purchased for each individual model. We carry a large number of Alpha boiler spares, ranging from small and inexpensive parts right up to parts such as the Alpha CD PCB, gas valve or pump assembly. The Alpha CD PCB sends messages to various parts of the boiler based upon feedback it receives from the thermostat. When a message that the temperature in the property is too low is received, for example, the PCB instructs the boiler to fire, producing heat. There are also vital safety checks carried out by the printed circuit board, ensuring that the fan is in operation prior to gas being ignited, for example, to limit the chance of a build up of carbon monoxide. As you may expect, the Alpha CD gas valve is responsible for controlling the flow of gas to the pilot light and the burner, ensuring the correct volume of gas is burned to produce the desired level of heat in rooms or hot water to the taps or shower. As with any work that needs to be undertaken on a boiler, it is vital that your Alpha boiler spares are installed by a fully qualified and competent Gas Safe engineer. Only registered engineers are guaranteed to carry out work safely.
