Boiler Breakdown Callouts in Old Town Swindon

Not necessarily. In tall period houses, top-floor radiators are usually the first to suffer when the pump is weakening, there's air in the system or sludge is restricting flow. If the boiler itself is running normally, it may be a system problem. If it's also cutting out or showing a code, call me.

A cylinder that runs out early can have a failing cylinder thermostat, a coil coated in scale, or a boiler that isn't heating it properly because of a valve fault. Tell me how long the hot water lasts compared with before, and whether the boiler is showing any faults.

Yes. I cover Old Town as part of my Swindon area, along with Coate, Wroughton and the town centre below. It's about 6 miles from my base in Highworth. Give me your SN1 or SN3 postcode when you ring.

Just safe access and some light. Clear the route down and the space around the boiler, and point out where the gas meter and stopcock are. If the cellar is damp or water has collected near the boiler, mention it when you call, as that can affect the electrics.

Tell me exactly what work was done and where. Disturbed pipework can cause a leak, let air in or dislodge debris that blocks circulation, and a moved wire can affect the controls. Check the pressure gauge and look for damp around the work area, then call me.

Knocking or ticking as the heating warms up or cools down is often pipework expanding against floorboards or joists, which is common in older houses and usually harmless. Loud banging from the boiler itself is different and can point to overheating. Tell me where the noise comes from when you call.

Pressure that rises on its own often means the filling loop valve is letting water through, or the expansion vessel has lost its charge so the pressure jumps as the water heats. Above around 3 bar, the relief valve may discharge outside. Note the readings hot and cold and call me.

Usually a boiler fault doesn't affect other gas appliances, so a properly maintained gas fire can still be used. If you smell gas, notice soot or a carbon monoxide alarm sounds, turn everything off, get into fresh air and call 0800 111 999 first.

If the boiler is reaching temperature but the radiators aren't, the heat isn't getting round the system. A failing pump, a stuck valve, an air lock or sludge are the usual suspects, especially in larger older houses. Switch the heating off if the boiler starts cutting out, and call me with what you've seen.

Yes. In older properties it is common for what looks like a boiler breakdown to start elsewhere, in a valve, the pump or the pipework. Ask about where the fault is, what fixing it involves and whether anything else is worth keeping an eye on.
