Shower pump

[jonlea]

I want to increase the pressure on the shower head coming from a mixer tap in the bath. The problem is that the hot water supply tank is just a foot above the shower head whilst the cold water comes straight from the mains at 1.0 to1.5 bar pressure. Can I put a single impeller pump in the outlet supply pipe from the hot water tank, which is situated in a cupboard in the room next door to the bathroom? I get the impression from the adverts for these pumps that i should not use just one single impeller pump on the hot side only but I don't understand why if the pressure outputs are roughly the same?

Is the mixer on its own supply? If not then youll be pumping the hot water supply through the whole house......

No the mixer tap is not on its own supply but what would the harm be if the hot water was pumped thorugh all the taps in the house?

No harm, Salamander do a pump specifically for this purpose, although youll have to fit either an Essex. Surrey or Wessex flange to supply the pump. Grundfoss also make a 'whole house pump' but its a big bugger!!
