My ravenheat condensing boiler lights and then goes out and then lights and then goes out and so on - the rads do finally get to temperature and the domestic hot water gets hot - any answers - the boiler is only 2 years old - hearing the bolier coming on then going off repeatedly is disconcerting any answers
