Top tips to keep your central heating in good shape
Step One
Never run your central heating system without an inhibitor. To tell if you have enough, take a jar with a screw lid, and fill it with some water from the header tank. Put some steel or iron nails in the jar, and screw the lid tight. If the nails start to rust after 2 weeks, you do not have enough in your system. The presence of a good quality inhibitor prevents the corrosion and rusting of your radiators form the inside, and in so doing stops the production of gases that require bleeding. It also acts as a lubricant for the pump, helping to increase its life. Try the SCREWFIX site for various inhibitors (e.g. FERNOX MB1 97287, or SENTINEL X100 79683)
