Hi
I am adding a radiator in my conservatory. There is a radiator very close in the dining room but all the radiators in the house run off 10mm pipe, which goes back to 15mm feed pipes in the floor boards.
I know that simply teeing of the back of the radiator in the dining room will not work because of the flow restriction so I am thinking of going back to the 15mm pipes in the floor boards.
I have looked at the pipes in the floor boards and there is 15mm flow/return pipes which have a tee off to the dining room radiator (15mm to 15mm with 10mm branch) and at the end of the 15mm pipes there is another tee (15mm to 2 10mm branches) which feeds the back 2 bedrooms. So there are 3 radiators running of these 15mm pipes. The dining room radiator is 600x600 double and the bedrooms are 500x700Lg singles.
My questions are:-
1 - Am I doing the right thing in going back to the 15mm pipes &
2 - Is the 15mm pipes still going to give enough flow now that there will be 4 radiator's teeing off instead of 3. The new radiator is 600x900lg double.
If it helps I have a 18 month old Biasi Garda HE, Model M96.24SM - Max output of 85.295 BTU. At the moment there are a total of 7 radiators running. Please note that the 3 I have mentioned above are on seperate flow/return pipes than the remaining 4.
Hope this is clear.
Thanks
