I bought a new house 2 years ago. The boiler is an Ideal ICOS HE30.
The whole system was very noisy from day 1-sounded like rats running in the walls and even after bleeding air from the radiators it didnt stop. eventually we got the builders to come back (Bryant homes) and flush the system and they removed a bucket full of metal filings, plastic filings and grit. 8 months later the boiler "exploded" there was a very loud thud/bang and water sprayed out of the exhaust vent outside the house.
It was the heat exchanger that blew up when the inlet and outlet got plugged with dirt from somewhere, so the water inside the exchanger boiled and BANG.
The system was flushed again and a complete new boiler-(same model) fitted.
Now we still had squirly noises in the radiators and I bled off "air" from some of the radiators. Also the pressure kept creeping up from 1 bar to about 2.8 bar, until the relief valve started weeping- there is a weird "view port" on the drain line so you can see the dripping.
Plumbers came back and removed the system filler hose and bled the pressure back to 1 bar. Now the filler hose is still disconnected and blank caps are on the filler connections
Now every 2 weeks or so I have to bleed "air" out of the radiators- the pressure creeps up to 2.5 bar or more, and I bleed it back to 1 bar. I have done this 7 times now- the plumber doesn't believe me...
Anyone have any idea what is going on? The only thing I can think of is that some kind of gas is being generated inside the system, but that sounds crazy?!?!?
