Combi Boiler Stops Heating
Hi,
Our combi boiler fires up when we put the hot tap on but after about 30 seconds it then stops again. After another 30 seconds it repeats the process. Unfortunately this means we are unable to use the shower. A British Gas engineer came round and, just by switching the hot tap on, told us that the problem is not the boiler but the mains pressure into the house and requested to call the water board. They stated that if the neighbours are unaffected this would be unlikely (which they are not). Also, the radiators still heat okay (although they do not require the boiler to be constantly on). Anyone have any ideas? I don't want to resort to digging up my drive unless all other avenues have been explored. Thanks Neil |

It's a Potterton - around 5-6 years old.
Although the radiators are hot, the boiler still emits a similar pattern when heating just the central heating, i.e. on for a short period, off for a short period. I may be wrong, but I think the boiler used to fire for much longer when heating the radiators before the flame going out. Would that still point it to the diverter valve? |

One other thing. The cold water pressure from my taps is very high, the
hot water tap not so high. |
