i have a heat line combi c 24 compact.installed 1 and half yrs ago.
with pressure at 1 bar on start up (firing) if left pressure creeps up and into the red after 50 mins poss.(no thermostat )so on constant. it has worked ok like this but in the last 2 days ,in the morning i have had to top up pressure.
is it A. aleak? or B the pressure valve expelling the water .if not used the pressure dosent drop..........can the pressure valve be replaced ,and if so are the parts easy to get hold of??????
