Boiler type: Thorn EMI- Apollo
Problem: The temperature of the house is below the temperature set by the thermostat- so, naturally, the boiler comes on. However; the boiler only fires for ~5 seconds, turns off, waits for ~1min, and then fires up again. This process is repeated until the temperature on the thermostat is reached- which, because of the intermittent firing, takes rather a long time.
Does anybody know why this may be occurring?
Thanks.
