Hi guys, I am thinking of adding a new radiator in our kitchen but, although i'm quite generally handy I would like to know the correct way of doing this as in theory it would be tapping into the boiler CH output an making the radiator i fit the first in the system.
As im sure you are all aware the output pipes are 22mm but a radiator is 15mm, is it really as simple as cutting into the pipe, running 22mm pipe to the radiator ( with a 15mm reducer to connect up ), same coming out (15mm to 22mm ) then connecting back to where i cut in ?

It depends on what sort of system you have... you need to be sure these pipes are not Primary flow and return
 
Ah thanks for this, I had a funny feeling that it wouldn't be as simple as i was thinking, so would I need a 15mm reducing tee in both the CH feed and return 22mm pipes above the boiler to the radiator....or in turn would this upset the whole system/pressure.... connecting one up in the traditional way is very difficult with pipes being in walls and under floors.... this plus the fact the radiator is to be hung on the wall behind the boiler

Adding a new radiator to an existing system also needs building control.
 
You may be correct but I've never applied for BC to fit a radiator and I'd say most plumbers/heating engineers haven't.

Well well well now we know where all that global warming is comming from.
 
Err no flow and return pipes from boiler need a connection in each reducing tees 15mm to rad all the way.

Just re-read this reply and it answered my next question, thanks again.... it actually does sound pretty straight forward now, i was on the right track then, just need to connect the out valve to the return pipe via 22m tee
