Boiler controls can cause various problems. Checking your thermostat, programmer/ time switches and radiator valves can help, however don’t ever attempt to do any complex servicing or repair work on your heating system yourself and always seek the skills of professionals such as Croydon Plumbers and keep in mind that all boilers and heating systems should be serviced and checked regularly by a professional. Over time, thermostats can lose their accuracy, misreading temperature settings and turning the heat on/off at incorrectly. Be advised that while a gas boiler engineers such a Croydon Plumber can clean and recalibrate your old thermostat, it might be wise to have them install a new one. A thermostat will warm your house when you need it and turn the heat down when you don’t cutting heating bills by 10 to 20 percent. The hot water and heating are controlled by the timed/off/constant switches found on your boiler. Check that the LCD display is reading accurately. If you have a thermostatically controlled valve, then turn it up. If you have a conventional lock shield valve, then adjust the setting.If no change occurs after you’ve adjusted the settings, you have a fault with your radiator valve and will need to call a Gas Safe registered professional to drain the system and replace it and of course the work will always be guaranteed. Condensate pipes carry condensation from your boiler to your outside drain. When the weather is really cold this pipe can freeze and cause a blockage causing a shutdown. If the condensate pipe freezes your boiler’s lcd display should provide some kid of warning for you a like a light or code. Following the above advice is good but any doubts about your DIY skills should result in a call to the Professionals.
