Hi all,
I have a unvented central heating system running off a 25kw biomass boiler. I have an issue with three radiators in the house not heating correctly. The flow is hot but the return is warm.
The three new rads are on 15mm pipe with reducing down to 10mm on the drop to downstairs. It then comes back up in 10 and picks up the 15mm return.
I have just pulled some floor boards out and discovered that the 15mm return has then been connected up to 10mm tails left by the removal of an old rad.
Could this be the problem? Thanks ALex.
