I've just added a new radiator in the utility and its working well but when I revealed the 22mm feed and return to tee into (15mm), it became apparent that they come down from the boiler upstairs and the ground floor rads are teed off in one 15mm loop and then proceed to go upstairs in 15mm to feed the first floor rads. Does this mean I have a mixture of one and two pipe systems? all rads get hot and the system appears healthy, we had a new WB30CDi fitted last year.
So, as it seemed somewhat odd to have the 15mm going back up to the first floor (may have been due to the original boiler beiing located in the utility and BG replaced it with a WB28 just after we moved in so maybe didn't do it very well!!!?) I propose to tee off at 15mm from the 22mm feed and return upstairs nearer the boiler to feed the first floor rads then the tee down at ground floor level will only be feeding the ground floor rads. (I'll obviously be able to remove the 15mm pipes going back upstairs as part of the 'tidy up'!)
Sorry if thats a bit of a ramble but hopefully you'll get the picture and it sounds the way to go to me or should I leave well alone as its working fine?
