    Hi, my combi is protherm lynx 24. I set it to 40 degC to take shower and open hot water, the display shows current water temp, shortly(1-2min) the number on display rises to 80-90 degC, and thinking that the water is hotter than set value it cuts off the flame(gas). Water starts to flow cold...

    10mm pipework for cold water..why not?

    why is 10mm pipe not used for taps/toilet outlets? Why do I need the same diam pipe at the wash basin or toilet as I do at the bath or shower? I can't think of a reason why not so before I implement this, have I missed something that's not so obvious to a layman?
