Hi,
I'm replacing an ideal Mexico with a Potterton Promax SL (30Kw). The original heating pipework is 28mm from the boiler. I'm upgrading the system, so fitting a 3 port valve and also a magnaclean. Space is fairly tight and the pipework needs a fair bit of rerouting, so I was going to do the first couple of meters of the flow and return in 22mm instead of the 28mm currently installed.
Does anyone think there would be any issues with this?
Cheers
