downstair radiators come on when they feel like it except lounge but not for long
fitted two new rads downstair when decorating with trvs to all rads
sealed system running at 2.5 bar pump sometimes noisey
and trys to select another gear when running

[rosebery]

Air is a primary suspect in both rads and pump resulting from your decorating work.

Did you upset the heating balance?

Can your boiler cope with the extra demand you have placed on it?

When you say "sealed" do you mean sealed as in combi boiler or sealed in that you have a system boiler with an unvented cylinder?

Cheers
