Before you call out a heating engineer,
why not check our Help & Advice section to see if there is a simple solution to you problems.
Many Central Heating issues are simple to fix and you will find answers to some of these below:
1. Central Heating wont come on.
Does your boiler have power? Are the lights on front lit up? check that the electrical spur or plug is not turned off. Does your boiler have a reset button – dont be shy just press it
2. Water pressure – Is the water pressure gauge low? (low is anywhere below 1 bar)
If the system pressure drops too low your central heating may not come on.
Try filling to around 1 bar to top up the pressure – most heating systems have a filling loop underneath the boiler – filling is done using a tap or ‘trigger switch’.
If your boiler keeps losing its pressure, or the pressure is high, this could be a sign your boiler is broken.
3. Radiators not heating up properly?
If its cold at the top and hot at the bottom then your radiator may be full of air.
Try bleeding air out using a ‘bleed key’, a small key with a square hole inside that fits the valve on the top side edge of your radiator. Open the valve slightly until you hear air hissing as it escapes – do this slowly until a small amount of water comes out.
4. Fault code on Central Heating display ?
Try a google search, sometimes the answer can be found on google.
common fault codes are well documented on the internet and googling the displayed code may give you the information you need.
5. Burst water pipe? find that stopcock!
Everyone should at least know the location of their stopcock, which is the mains water supply shut-off. If the stopcock is stiff try pliers to help turn it. Or get us to fit a surestop which replaces your stopcock valve with a switch which shuts off the water instantly!
