First of all sorry if this has been mentioned before!!
We are doing some work on our house to sort some damp out so the plaster is coming off several walls. Downstairs we have solid concrete floors throughout. Three of the downstairs radiators have there flow and return pipes running to whatever rooms are above. i.e living room pipes run up the wall to the landing and the dining room pipes run upstairs to the spare bedroom, etc. When we first moved in last winter these 3 radiators only got luke warm, so I did all the obvious things. (Bled all radiators but no air apparent, took downstairs rad's off which were full of black stuff and flushed,etc).
The upstairs radiators get hot no problem so I turned all of those off at both ends and the downstairs rad's get hot also. What I'm thinking is, would the system be more efficient if the downstairs return pipes don't run back upstairs but a re-plumbed to stay downstairs and run to the gloworm combi boiler (which is located downstairs)? It seems like trying to push the cooling water back upstairs to come back downstairs somewhere else in the system is pointless? The pipework is 10mm copper at the radiators but larger under upstairs floorboards,the boiler is a glow-worm 30ci plus (believe to be approx 8-10yrs old) with 11 radiators. All have TRV's apart from bathroom radiator.
Cheers Edd
