Boiler Repairs

Boilers have a series of control mechanisms which are designed to distribute heat and hot water at peak times. Boiler problems can be caused by faults within these controls, and, as a result, can run up your fuel bills as well as make your home uncomfortably hot or cold.


Carrying out simple checks to your thermostat, programmer and time switches, the electronic programmer and radiator valve may help to solve some boiler problems. These are things you may wish to do yourself and we offer some suggestions below as to things you can check. However don't ever attempt to do any complex boiler servicing or repair work on the heating system – for this you should always seek the skills of a Gas Safe Register approved heating engineer. And remember also that all boilers and heating systems should be serviced and checked regularly by a professional. This will prevent any future boiler problems and expensive emergency call outs.


One thing you can do is to check the age of your thermostat. Over time they can lose their accuracy, misreading temperature settings and, as a result, turning the heat on/off at incorrect times. Be advised that while a gas boiler engineer can clean and recalibrate your old thermostat, it might be wise to purchase a new one with extra energy-saving controls at your local DIY store.


Programmable thermostats are very useful as they warm your house when you need it and turn the heat down when you don’t – they can cut heating bills by 10 to 20 percent.


You can check that the LCD display, circuit board electronics or relay hasn’t failed. If you already have a standard universal backplate behind a failed electronic one, a replacement usually just plugs straight in its place (the same way a plug fits into a socket). These can be found at most DIY stores. Simply remove the retaining screws holding the unit onto the backplate and then fit the new one.


Some programmers are mechanical time-clock driven. Something for you to check when there are issues is that the clock dial isn’t stuck. If so, the program on/off timing will be wrong. The hot water and heating are controllable via the timed/off/constant switches found on your boiler.


If you have a thermostatic valve, then you have the option to turn up the thermostat. If you have a conventional lock shield valve, remove the plastic cover and adjust the setting.


You should be aware that you have a condensate pipe which carries condensation from your boiler to your outside drain. During extremely cold weather the condensation in this pipe may freeze and cause a blockage causing the condensate to ‘back up’ into the boiler and cause a shutdown.


Signs that the condensate pipe may have frozen include your boiler’s display showing a ‘fault code’ or it may have a warning light there may also be gurgling or bubbling sounds coming from the boiler or the condensate pipe.


If you suspect this is the problem, see our guide below on how to defrost a condensate pipe this should get your boiler working again in no time. If you suspect that the element in your boiler may be furred-up with limescale, you can also follow this guide.

When you have carried out these checks and cannot find the fault, or indeed if you are not happy to do any of the above yourself, then please call us out at Coleraine Plumbers and we will be happy to come to your home and offer advice and a quote on any repairs required.
