Signs Your Central Heating System Requires Repair

Knowing the early warning signs of central heating problems can save you from costly breakdowns and ensure your system remains safe. Some symptoms that warrant immediate investigation by a professional plumber and heating engineer include:

Our Services

Cold Spots on Radiators: This indicates that air is trapped in the system or sludge is affecting water circulation, which reduces heating efficiency.
Inconsistent Heating: If certain rooms in your home are warmer than others, it could be a sign of a system imbalance or a faulty pump.
Pilot Light Issues: A pilot light that frequently goes out or has changed from blue to yellow may indicate a carbon monoxide issue, requiring immediate repair.

Strange Noises: Banging, clanging, or whistling sounds from your boiler or radiators can indicate limescale buildup or low water pressure.
Boiler Pressure Issues: Constantly fluctuating boiler pressure is a clear sign that your central heating system needs attention.
Homeowners around Gloucester and Cheltenham who address these signs early on can prevent more severe central heating breakdowns, and ensure their systems operate safely and efficiently.

Common Central Heating Repairs We Undertake

Alsto-Heat carries out a range of central heating repairs, each tailored to the specific needs of your system. Here are some of the most common repair tasks we undertake:

Radiator Bleeding & Balancing: If your radiators are not heating up evenly, we balance the system to ensure each radiator receives adequate hot water. We also remove air from the system, restoring full efficiency.
Thermostatic Valve Replacement: Faulty or inefficient valves can make it difficult to control room temperatures. We install new valves to improve heat distribution and energy efficiency.
Pump & Motorised Valve Replacements: If your system isn’t circulating water properly, it could be due to a malfunctioning pump or motorised valve. We diagnose and replace these components, ensuring your central heating works as intended.

Boiler Repairs: As experienced plumbing and heating engineers, we handle issues related to low boiler pressure, faulty thermostats, and broken components such as diverter valves. Our repairs aim to extend the life of your boiler and prevent future breakdowns.
System Flushing: Over time, sludge and debris accumulate in your central heating system, reducing efficiency. We perform system flushing to clear out this buildup, ensuring optimal water flow and reducing the risk of faulty central heating.
