Two viessman boilers that work in tandem. Noticed upstairs radiators weren't getting hot because of air.
Turned off boilers, bled the radiators. There was a lot of air trapped, so had to continuously repressure the system was I was bleeding.
About 90 mins later (I was doing other stuff in-between), ready to start boilers again.
Pressurised to 1bar, switched them on. Everything seems ok.
All of a sudden pressure rises sharply on both boilers, into the danger zone and bang! one of boiler goes. I switched power off and called boiler technician out.
Looks like a pipe exploded because of the pressure. I'm trying to figure out how that happened? Definitely put it to 1 bar, and switched on when the system was cold.
Any ideas? Need to get the boiler repair but don't want this happening again
