One of the most common problems with boilers is a lack of heat or hot water. This issue could be caused by various factors such as a malfunctioning thermostat, a broken diaphragm, airlocks, or a faulty pilot light.
If your boiler is making unusual noises such as banging, whistling, or gurgling, it could indicate underlying problems. These noises might be due to trapped air in the system, a buildup of limescale, or a malfunctioning pump or heat exchanger.
Leaks in the boiler or surrounding pipes can cause water damage and reduce the efficiency of the system. Common sources of leaks include damaged seals, corroded pipes, or a faulty pressure relief valve.
Low boiler pressure can lead to reduced heating performance and potential damage to the system. This issue may be caused by water leaks, bleeding radiators, or a faulty pressure relief valve.
