I really want to keep these two separate but it may be linked.
1. For some time now I have had to bleed one of my radiators weekly, its the furthest away from the boiler, also there appears to be a lot of air in the pipes bubbling around when the heating is on!
2. Having read the posts relating to the above which suggested the pump speed was too high so I adjusted the pump speed on my Grundfos from 3 to 2 to see if it made a difference, all it did was produce a kettle like effect in the boiler which heats the water and then shuts off.
Background info.
Myson Apollo boiler, Grundfos 15-50 pump (crud around the top but dry, no leaks from the pipes/rads that I can see, expansion tank with water in and the float vale works)
Wondered if anyone could give me an route be fore I call out the professionals.
Thanks in advance
