i,ve got an alpha cb24x combi boiler thats just under 2 years old.i recently noticed that when heating is on boiler fires up,stays on for less than 5 mins then goes off,then within 5 mins it fires up again and does the same and continues doing it until heating goes off.im not sure how long its been like this or even if its always done it but it doesnt seem right to me.any ideas???
