I have a wall mounted heat only condensing boiler with 3 way motorised valve and combined feed/vent and 8mm plastic pipes. I always have to bleed the rad. in bedroom. Can anyone please advise ? Many thanks. Malcolm
Many thanks for your response HTG Engineer. The boiler is not a combi and therefore not pressurised. It does not appear there is a leak as nothing is showing on ceiling. I have been told that it may be the quality of the plastic 8mm pipe insomuch as it may be porous thereby air is permeating through the pipe walls. Is this possible ? the heating was fitted in my new house 10yrs ago. Can you please suggest a branded leak sealer. Many thanks Malcolm.
