Hi,
We're in the process of a kitchen extension - old kitchen was a smaller extension which was demolished and building a new one.
Trying to work out what's going on with the heating so we can add two new radiators, bigger one in new kitchen and a smaller one in utility and toilet. We're got a combi boiler, and what looks to me like a mix of one pipe and two pipe system. I've taken up some floor boards above where the pipes go into the kitchen, and the bedroom radiator is teed of the same pipe - it does have a TRV but not sure if it is a one pipe TRV or not, any way to tell? Further over I can see two radiator pipes off separate pipes, teed off to kitchen and living room radiators.
10mm pipes are going into kitchen now for the old rad (capped off), but I've read that I shouldn't be teeing 10mm for multiple rads, especially as the new kitchen one is a double vertical radiator.
What's the best option here? Easiest obviously to extend the two 10mm in extension, but not sure that is a good idea. Or feed new 15mm pipes into extension and go down to 10mm pipes closer to the radiators?
Thanks
