Replacement Radiators.

[henry smith]

I am about to replace all my rads/pipework.

I have a Baxi 105e combi with a total of nine rads (four down stairs and five upstairs).

I intend to use 22mm copper for the manifolds but am unsure whether to run 15mm copper or microbore to the rads.

Also I will be using a room stat for controlling the boiler, so should I also fit thermostatic valves?

Any advice appreciated.

15 to the rads microbore is cr*p

yes trvs but not in the room where you put the stat

What's wrong with microbore? I've been using it for 25 years and never had any problems. It's just a question of getting the pipe sizing right.
