I have been having lots of problems with my central heating, I have mircrobore pipes, ideal standard Icos HE24 boiler, tvrs fitted onto rads. All the rads are getting hot, but some of the rads need constant bleeding as there is air in these rads, the water is fizzing as I bleed these certain rads. When you turn the heating on you can also hear the water run through the rads and eventually through the pump and the boiler. There is a pattern to this as the system will run for approx 1 to 1 half hours and then the boiler will make some bangs and then shut down, and continue this until I turn the heating off, if I leave the heating off for an hour and restart, the system will restart and then run for an hour to hour and half and repeat this continually.
I have tried different pump speeds, no change. Do I need a new pump or can this be blocked.
Is there problems with the boiler, have no problems with hot water.
Have been recommended to powerflush but reluctant as pipes are in the walls.
Have tried noise reducers and sentinel x100. Looked at tank in loft all ok.
Is there a leak any where, how is the air getting into the system as is a sealed system. Shall I take every rad off and run water through and drain system, do I need to drain boiler.
Really need help. Need a good plumber with knowledge of microbore. thanks.
