My father is looking at installing a power shower (NewTeam NT
1500-XT). This beasty does not have a separate pump - apparently one
is included in the control unit that you attach to the wall. You
simply connect hot and cold feeds, wire it up, and away you go.
The manufacturer's brochure says that the bottom of the header tank
must be 1m above the top of the maximum height of the shower head.
This seems a little excessive given that in most houses the tank sits
in the loft about 20cm above where the shower head is likely to be.
Does this seem correct? Is it likely to work with a separation of less
than the recommended 1m?
(Before you flame me with 'RTFM' type comments, I'm sure you've all
experienced situations where manufacturers are just trying to cover
backs by being over-cautious).
