Had Ravenheat cs120 installed last year by reg installer.System was losing water although complete new plumb radiators pipes all surface so no leaks in pipe work.Ravenheat rep called asked plumber to change gas line from 15mm to 22mm plumber duely changed.Kept topping up system.Boiler started to shut down making noises.Has anybody got ideas as to what the problem is.Me thinks the heat exchanger has a leak?Surely this is Ravenheat problem and should be replaced under warranty!!!
