Hi
first post and please excuse me if my terminology and understanding of this dark art is poor.
My 5 bed house started out as a 2 bed cottage , and I bought it in its extended state.
It would appear that the heating system has been extended in a haphazard way.
I fully understand that the vented system with a floor standing boiler and a pump for the CH and a second pump for hot water is dated , but it is what it is , and is reliable.
So my problem:
The CH pipes from the boiler are 22mm and as you would expect , the flow and return run upstairs to a cupboard with the hot water cylinder.
To start with , at ground floor level , there is a 15mm loop buried in the floor feeding 4 old radiators.
This pipework is set in concrete and I suspect is leaking , so I propose to dig up and replace with 22mm , and feed the new rads with 15mm tails - is that ok ?
Secondly , in the airing cupboard there is another 15mm loop feeding 2 upstairs radiators. These get very hot.
Thirdly , there is a single straight spine of 22mm flow and return running down the centre of the house , with several long 15mm loops attached.
Naturally trying to balance all this is a real nightmare , and some rads just dont get hot.
So , my proposal .
As above - set the downstairs 4 rads in 22mm with 15mm tails.
Then , get rid of the straight run upstairs of 22mm with all of its loops , and instead run from room to room in 22mm to create an arc so to speak , so that the 22mm is closer to the rads , and have short 15mm tails to the rads.
This way I will eliminate all of the upstairs loops and effectively have a single circuit upstairs.
This might sound naive , and maybe not even logical , but I need to do something.
All opinions are most welcome
thanks
Steve
