32mm MDPE DZR Stopcock

Product Information

Yes, the DHW outlet for a domestic combi boiler will only be 15mm , generally most just T off as you said. I suppose you still could go straight into a 22mm manifold then off to appliance in 10-15mm if you felt there was some benefit with that setup. Water meters are usually more expensive than 15mm, but you will get the associated flow reduction going to 15mm instead of 22mm.

I haven't done calcs yet but Barney mentions the possibility of running 28 mm from the HWS generator to first floor and then on in 22 mm to the second floor (we're running two showers off the boiler): So I have a 24kW combi, with a 22mm supply pipe from the road (length 10 metres or so), until up close to the boiler. Pipes from the combi to points of use are mainly in 10mm PEX or 10mm copper. Pipe Fittings Compression Fittings Brass Fittings Press Fit Fittings Push Fit Fittings Solder Ring Fittings

This is the problem with having lots of different threads on closely related subjects: I'm fairly sure Shevek said something about his lot wanting their own meter for monitoring purposes separate from the water company's one but maybe it was somebody else and I, for one, can't be bothered to search.
