They can also give you simple tips to help avoid the same fault.
We repair boilers in kitchens, lofts, garages and cupboards. We help homeowners, tenants and landlords alike. It helps to have the boiler's make and model to hand when you book.
Boilers work hardest in winter, so faults often show up when it turns cold. The heating may not come on at all, or it may only warm some rooms.
First, check the thermostat is set above room temperature and the timer is on. A timer that has reset after a power cut can keep the heating off. Then check the pressure gauge. For anything beyond these checks, our boiler engineer in Llanelli can help.
If the boiler fires but the radiators stay cold, the pump or a valve may have failed. If the boiler won't fire at all, the fault may be with the ignition or a sensor.
In very cold weather, a frozen condensate pipe is a common cause. The boiler shuts down and may show a fault code. Thawing the pipe with warm water often gets it going again.
Running the heating for short periods each day in a cold spell helps. It keeps water moving and makes a freeze less likely. It also shows up a fault early, before you need the heat most.
Bleed any radiators that are cold at the top before winter starts. Check the gauge afterwards and top up the pressure if needed. These small checks help your heating cope when it gets colder.
Try to note any codes, noises or leaks before the visit. Your engineer can use these details to find the fault sooner.

Usually a leak somewhere in the system. It might be a radiator valve, a pipe joint or a part inside the boiler. Bleeding radiators also lowers the pressure, so top it back up to 1-1.5 bar afterwards. If it keeps dropping, an engineer needs to find and fix the leak.
