    Thx for your reply. I had a plumber in last week- the loop was open. He drained some water thru radiator and pressure has dropped. A lot of kettling going on but all ok so far. Altho', presure has now dropped to 0.5......... : :?

    Combi 80 pressure 3-4 will I blow up?

    Dear Oilman, Thx for your speedy reply. We have never had a service. Apparently new boiler when moving in May 03, we've had a gas safety check 1.5 yrs ago when a different fault occured and a part was replaced. Thx.
