Boiler Repair

Experiencing problems with your heating system? Contact us at any time for our round-the-clock service. We will send a certified technician to your residence to assess and repair your boiler or heat pump, ensuring it operates smoothly once more.

Boiler Maintenance

Maintain peak performance and avoid malfunctions in your boiler by scheduling annual servicing with our team. An autumnal inspection readies your boiler for the winter ahead, improving its efficiency and dependability.

Boiler Replacement

Should your boiler be old or in need of major parts replacement, choosing a new system might be more cost-effective than repairs. Our certified experts will provide a detailed evaluation and assist you in making an informed choice.

Typical Problems Encountered During Service Visits

Boilers, like all mechanical systems, can experience a range of common issues. Early recognition of these issues can prevent more severe problems. Here are the most common boiler problems we see:

  • Lack of Heating or Hot Water: The most apparent issue, which could stem from malfunctioning diaphragms, airlocks, motorized valve failures, thermostat problems, or insufficient water levels.
  • Water Leaks and Drips: These suggest a failure in internal components like pressure valves or pump seals. High boiler pressure might cause leaks from the pressure valve. Our technicians can identify and address the cause of the leak.
  • Unusual Noises: Whistling, gurgling, or banging noises, known as ‘kettling’, might be due to air in the system, a malfunctioning pump, low water pressure, or limescale build-up on the heat exchanger.
  • Extinguished Pilot Light: Causes might include a defective thermocouple, soot accumulation blocking the gas supply, or drafts.
  • Low Pressure in Boiler: Problems such as leaks, defective pressure relief valves, or recently bled radiators can reduce boiler pressure, affecting performance. Our technicians can resolve these issues.
  • Condensate Pipe Freezing: In cold weather, the condensate pipe of modern boilers may freeze, blocking the system and causing failure.
  • Thermostat Problems: Thermostats may lose accuracy or efficiency over time, leading to erratic heating or lack of hot water.
  • Radiators Not Warming: This could be due to sludge or air in the system, often fixable by bleeding the radiators or system flushing.
  • Boiler Shutting Off: This could be due to low water pressure, a blocked condensate pipe, air in the system, or thermostat issues, requiring further investigation to identify the cause.

Regular servicing by a qualified technician is crucial for maintaining a boiler’s longevity and efficiency, minimizing the chance of unexpected failures and expensive repairs.
