guydewdney, that's the thing, the hot comes at you full pressure, so none of this piddling flow or power shower stuff, one just gets blasted.   extrahappy

You wouldn't get blasted with my mains water pressure.  Only for the water in the header tank I wouldn't be able to wash the shampoo out of my hair!

I have constructed a special 'dunking' machine. If you can imagine a trolley board car mechanics use attached to a bungee cord, on a downward track with a special three dig mechanism.  Patents pending.

The more sophisticated amongst us manage to have mains pressure hot water and a vented tank.

 clivjo,some ten years ago,
                    when i built this house,like your water,the pressure was usless to say the least,so i studied the cage tanks which were just available then for 25 sterling across the border in the north. the plastic was exellent and idea for connecting brass or placky so i chopped 9 inches of the 1200ltr tank and set it up into the loft where it was supported by blockwork wall running up from the founds.
     the tank is measured out in increments of 100ltr and when the ballcock is at rest it holds a nice 600ltrs +. this was sufficent to carry us over any period when the mains was off.as it turned out,it was a very wise move.new houses sprung up along our road and zealous digger drivers tore up the mains on numerous occasions.the only thing you have to remember using one of these,is to also cut the steel cage and reinsert the steel rim at the top,this keeps the tank from spreading with the weight of the water.the tank supplies two kitchens,two bathrooms and two showers.
  i have a fear of fire,a genuine fear like my dad before me so i connected a 2" pipe to the origional outlet on the tank which can be activated giving 600ltrs of water pronto,i hope i may never need it.the place is alarmed enough as it is and with two good dogs to tell us whats up we should get plenty of warning.still having it on the ready gives piece of mind.so its an idea worth considering.

 i fitted wax valves on the showers which were driven by gravity feed,the upstairs one is fine,even though the shower head and the bottom of the cold water tank are only 950mm apart.the downstairs one has more than ample pressure. the wax valves are temp sensors valves and react much quicker than any lecky one i used before. the hot water cylinder is a double indirect with2 x  8mtr quick recovery coils and it really does what it says on the tin.
  the heating and insulation in this house was so efficent that i removed two rads and have another 2 permanently switched off.origionally there were 15.
  i think i described the system here on navitron before but the heating system is also designed to run on gravity,with the gravity side of things being controlled by a flap valve to stop recycling when the pump comes on.
  looking back,if i was going to do it all again,i would use less placky or use my german barrier pipe.the hepworth 2 requires extra push from the pump and comes alive when heated creating little hollows which take a few minutes for the pump to master,however you have to balance that off against the fantastic insulating qualities and less heat loss off the placky enroute.

Nice example on greenbuildingforum.   There is a drawing of the system about half way down the first page.
