Is your boiler also loosing pressure?
Your boiler pressure gauge should measure between 1-1.5 bar. Too little pressure could lead to inefficiency and high energy bills and as the cold months are now upon us and we all have turned the boiler back on to get that central heating fired up that could amount to some unwanted expensive bills. Checking your pressure Gauge and ensuring it is within the recommended level could save you a quid or two. If you find yourself having to reset the pressure on the boiler often, let that be a sign that something is up. Have a look at your radiators and see if you can find an obvious leak as this is a common diagnosis relating to loss of pressure.
