Essential Winter Checks

As the days grow shorter and the temperature drops its important to BE PREPARED. These simple checks are all you need to know to make sure your heating system is winter ready!


  • Firstly, it’s important to know what type of heating system you have in your home!  Do you have a hot water cylinder in the airing cupboard? Tanks in the roof?  Do you know where your pump and controls are located? And lastly, what type of boiler system do you have…. Perhaps you have a combination boiler with hot water instantaneously from the boiler and no storage cylinder.


  • It is always a good idea to check that your central heating works before it gets too cold! Make sure you are prepared and don’t get caught in the cold!


  • Turn on your heating controller and make sure all your thermostats are on maximum  (the highest number) , including your individual radiator thermostats.


  • Check your radiators to see if they all get hot, if none do get hot it can be a faulty circulating pump, faulty zone valve, or faulty room thermostat (again sure all thermostats are turned up to maximum)



  • If you find that your radiators only get hot half way up they may need bleeding. If you have a pressure gauge make sure it’s set to between 1-1.5 bar (do not over-pressure it)!


  • If only one or two radiators don’t heat it might be that thermostatic radiator valves themselves are sticking, sometimes by removing the valve head and wobbling the pin it helps to free the thermostat.


  • Check you water levels either on your pressure gauge or,  if you have tanks in the loft,  you will need to check the small roof tank next to the larger cold storage tank.


  • Always check lagging is intact in your loft if it contains pipework, as it can become dislodged if you are grabbing storage, luggage or other items during the warmer months from the loft.


  • Finally make sure your boiler and boiler system have been serviced and are safe for use.


An annual boiler service is essential to ensure your boiler is working to its maximum efficiency and significantly reduces the risk of a boiler breakdown. All boilers, be it gas, oil, LPG or electrical will benefit from an annual boiler service!
