combi DHW supply/flow pipe size
Hi folks,
need your advice on pipe size - what would you recommend (15mm or
22mm) as a supply (cold) to and flow (hot) from combi boiler to taps?
Boiler can produce 14 ltrs/min so one would think that 15mm pipe is
enough. However there are opinions that 22mm is preferred because
boiler will get priority in getting cold water.
thanks for any info,
