Hi folks. CH/HW system is driving me nuts at the moment. I have an 18 month old Worcester Greenstar 18Ri (which thankfully appears to be working fine after shutting down the other morning with a frozen condensate pipe). Prior to this problem we'd intermittantly had HW problems - not very hot...

Hi, I have a Worcester Greenstar 24i junior. This morning the boiler was making strange noises and has since failed to work. Due to the cold weather I have tried to warm up the outside condenser pipe (just incase of it becoming frozen) but this has not worked and was not frozen. The fault light...
