Common Boiler Issues We Can Resolve
Low Water Pressure
A properly functioning boiler should maintain a pressure of 1.5 bar (as indicated on the built-in gauge). If the pressure falls below 1.0 bar, it may indicate a faulty pressure relief valve, expansion vessel, or a broken seal. Additionally, a leak in your heating system could be causing the pressure drop.
Boiler leaks can occur due to perished seals on the pressure valve or pump, corrosion in pipes, or poor installation. It’s crucial to have a qualified boiler installer fit and test your heating unit to prevent such issues.
Radiators Not Heating Properly
Radiators may fail to heat up sufficiently due to a buildup of deposits, trapped air, or a faulty radiator valve. A professional radiator repair expert can resolve these issues by power flushing the system or replacing the faulty component.
No Heating and Hot Water
This issue can stem from multiple causes, including a thermostat set too low, a leak in your heating system, valve problems, airlocks, no flame, heat exchanger issues, and more.
Hot Water but No Heating
If you have hot water but no heating, there could be a problem with the diaphragm, motorised or diverter valve, or trapped air in the system.
Pilot Light Going Out
A malfunctioning thermocouple or gas valve can cause issues with the pilot light, as can a broken seal. The pilot light may also simply need cleaning.
Banging or Kettling Noises
While a healthy boiler does produce some noise, unusual sounds like whistling, popping, rumbling, and banging indicate a problem. Limescale, debris, and sludge can accumulate in your boiler and heating system, particularly in hard-water areas of London. Trapped air can also cause strange noises. A water softener installation and a power flush can help address boiler kettling issues.
If your thermostat is displaying inaccurate readings or turning off your unit at the wrong time, it may be time to replace it.
Frozen Condensate Pipe
In low temperatures, condensing boilers can experience issues with the condensate pipe freezing and clogging, leading to a malfunctioning boiler.
Boiler Keeps Switching Off
This problem can arise due to a faulty pump, air in the system, low water pressure, a blocked condensate pipe, a malfunctioning thermostat or valve, or debris buildup.
