What does boiler servicing Coulsdon consist of?

When you hire Surrey Gas, our experts follow a rigorous, step-by-step protocol to peak your heating system's performance. During a standard service, we complete:

  • Verify pressure and seal integrity
    We monitor the internal pressure and hunt for hidden leaks, instantly fixing any irregularities we find.

  • Fine-tune control systems
    To lower your energy bills, we calibrate the thermostat and internal controls, so the boiler hits your desired temperature with perfect accuracy.

  • Deep-clean internal parts
    We strip down the accessible internal components to scrub away the grime, rust, and debris that stifle your boiler’s efficiency.

  • Visual assessments
    Our technicians examine the entire unit, checking the exterior casing, pipework, and structural connections for any signs of wear.

  • Analyse flue emissions
    Our team runs a full combustion analysis to measure fuel efficiency. This step confirms your system burns clean and minimises its carbon footprint.

Identifying common boiler issues Coulsdon

If you can recognise early warning signs your boiler is in trouble, this can save you from a total system breakdown. Here are the most frequent symptoms that require professional attention:

  • Cold spots in rooms
    Radiators that stay cold or only warm up at the bottom may be suffering from trapped air, stagnant sludge, or seized valves.

  • Silent poisoning (carbon monoxide)
    Blocked flues or poor ventilation can lead to lethal carbon monoxide leaks. This is a life-threatening emergency that demands immediate shutdown.

  • Poor fuel economy
    A sudden spike in your monthly bills often reveals a neglected, inefficient system that is working twice as hard to produce half the heat.

  • Internal overheating (kettling)
    When limescale coats the heat exchanger, the water ‘kettles,’ creating a loud boiling noise as the unit struggles to transfer heat.

  • Moisture and seepage
    If you see puddles by your boiler or water dripping slowly near your unit, it may be due to a number of reasons.

  • Winter thaw issues
    In really cold temperatures, the external condensate line can freeze solid. This may trigger a safety shutdown to prevent internal damage.

  • Ignition obstructions
    When the pilot flame flickers out or the spark fails, the boiler cannot ignite the fuel required to generate heat.

  • Intermittent cycling
    If your boiler shuts down randomly this could be because it senses a critical fault, like a failing pump or low water flow.

  • Total system failure
    Are you stuck with cold showers and chilly radiators? We can help with all system breakdowns.

  • Control misalignment
    A broken thermostat may ignore your temperature commands or cause the system to start and stop erratically.

  • Persistent pressure drops
    If your pressure gauge keeps falling, this could mean there us a hidden leak in the circuit or a malfunctioning expansion vessel.

  • Unusual noises
    If your heating system starts making banging, whistling, or gurgling sounds, call the experts. This usually signals trapped air pockets, a worn-down pump, or mineral deposits.
