Latest Tips and Information

A boiler that ignites but shuts down almost immediately can be frustrating, particularly when your heating or hot water stops working without an obvious explanation. One possible cause is a problem with the boiler flame sensor, an important safety component responsible for confirming that the burner has successfully established a flame. Modern gas boilers do not simply release gas and assume combustion has started. The boiler’s control system must confirm that a flame is present before allowing normal burner operation to continue. If the expected flame signal is missing or

An ageing boiler can become increasingly expensive to maintain, particularly if breakdowns are becoming more frequent, replacement parts are difficult to source, or the heating system is no longer performing as efficiently as it should. For homeowners in Sale, Manchester, replacing an old boiler can improve heating reliability, reduce the risk of unexpected breakdowns and provide an opportunity to upgrade the home’s heating controls. However, replacing a boiler is not simply a matter of choosing a newer model. The age and condition of the existing heating system, the size of

The gas valve is one of the most important safety and control components inside a gas boiler. It regulates the supply of gas to the burner, operating only once the boiler controls have established the conditions required for ignition. A modern boiler gas valve is much more sophisticated than a simple tap that switches the gas supply on and off. It works alongside the PCB, fan, combustion controls, ignition system and burner. On modulating boilers, the valve also helps regulate the amount of gas supplied as boiler output changes. Problems

A central heating system needs more than a boiler and circulation pump to move heat around a property. It also needs a way of controlling where heated water is allowed to flow. In heating systems divided into separate areas, this job is usually carried out by a zone valve. A zone valve is an electrically controlled valve installed within the central heating pipework. It opens and closes in response to heating controls, allowing hot water from the boiler to circulate through a particular part of the system. This makes it

The air pressure switch is a safety component found in many gas boilers. It is part of the combustion safety sequence and helps the boiler confirm the required airflow conditions before allowing ignition to continue. If the boiler cannot confirm these conditions, it should not keep trying to ignite. Depending on the appliance and the nature of the fault, the boiler may stop its ignition sequence, display a fault code or enter lockout. A faulty air pressure switch can therefore leave you with a boiler that appears to start but
