Hi all,
We have a gravity fed hot supply to our bathroom, currently all in 22mm pipe. We're about to completely gut the bathroom and replace it with a new suit, new tiling, etc. The bathroom is about 15m from the hot water cylinder, and with 22mm pipe it takes ages to get hot water in the bathroom. If I replace the pipe with 15mm then there's less metal to warm up, and less water in the pipe to flush through each time, so moving to 15mm would seem to solve our problem.
Will I get pressure drop problems? I don't want to slow down the bath fill rate too much, though I would accept it being a bit slower to fill if the hot water arrived sooner. As I understand it most modern bath taps are on 1/2BSP fittings, so will 15mm for the entire length make much difference to the fill rate over same taps but 22mm pipe?
All help appreciated
