Combi boiler not running long enough.

[dav657]

Tried everything g I can. Rad balancing (new 2 years ago). Baxi 105 is not running continuously long enough to bring rads up to temp. House still cold after several hours of heating being on. Boiler switches on max temp, quickly reaches 90 degs according to indicator lights, but switches off after 1 or 2 minutes, not allowing all rads to heat up and even those earlier on the circuit only get slightly warm. No room statt but all rads have thermostat valves set to maximum.

Boiler is 10 years old. Rads begin to get warm really quickly, so flow seems OK, however as the boiler prematurely knocks off they don't get the chance to heat up properly.

As above, not a diy repair.
