hi,
I have a fully pumped gravity fed heating system with thorn apollo 15/30B boiler, 6 radiators and a towel rad in the bathroom, I have a 3 port diverter valve, seimens rwb9 controller and indirect hot water tank. Ther problem is that the boiler gets very noisy when on high temp setting and the feed and expansion pipes get hot also the the overtemp trips and cuts the boiler out, when on low temp setting it is just a slightly niosy but bearable and does not trip out. I have tried flushing with sentinel x800 and then put sentinel x1oo in as an inhibitor but still noisy, can anyone point to a possible fault ??????????
