Hi
my house already had 11 rads fitted + a vaillant boiler which is rate up to apprcox 85,000 BTU's.
The pipe going to the rads is 10mm (microbore the plumber called it)
Anyway since i am redecorating and the rads have seen better days i decided to get new rads fited but I have decided to upgrade 4 of the 11 rads to double ones as the older ones did not heat the rooms enough. The total BTU's for the 11 new rads is about 50,000.
I had 2 peopl ein to give me a quote but they are giving me conflicting information.
A is saying that as I am changing some of the rads to doubles I need to have all the 10mm pipework in the house changed to 15mm stuff.
B is saying that it's ok for me to run the rads I want to the existing 10mm pipework and that 10mm piping is more common than people think.
So who is correct
Thanks
