Hi I have a Glowworm sxi boiler, the whole central heating system (closed system) is just 3 years old. The boiler used to run at about 64C and was constant at that temperature when there was demand for heating or hot water. Now as soon as it gets there it cuts out, the pump still goes, it cools down reignites, gets to 64C and cuts out again etc. I can raise the operating temp to 82C which gives the boiler longer to run but it does the same again when it reaches this temp. Does not matter whether its heating or hot water although it cuts out earlier with just water as it is a shorter loop. Anyone have any ideas its as if the boiler cannot regulate its own temperature or theres a blockage maybe preventing circulation although the rads do heat up. Any ideas would be helpful thanks.
