Refitting bathroom soonish, in early planning stages now.
Entire hot water to bathroom supplied from ground floor (it's a
bungalow) indirect HW tank via 22mm copper. I want a thermostatic
shower with a decent flow, a bath that doesn't take a week to fill and
a WC & Washbasin.
I need a shower pump for the shower, otherwise it just won't work -
the showerhead being higher than the HW tank (although CW feeder above
HW tank is a couple of feet higher, so may get a dribble - but not
enough to have a decent shower).
Question: Can I just put the shower pump on the incoming 22mm HW feed
to the entire bathroom, or is that a bad idea to have it triggering
for washbasin and bath and it should just go on the Shower feed?
BTW - CW - unsure if going to put mains or use a feed off the CW tank
in loft. Mains pressure ain't great, so prolly better to run a 22mm
down and avoid washing-machine induced scalds? It's on mains atm, but
I'm worried that a thermostatic shower will need more CW flow than it
can supply. (Weedy 15mm mains, so not only crap pressure, crap flow
Am I right in thinking that as it's unlikely more than one thing is
going to be using CW at any 1 time in the bathroom then a single feed,
with bits taken off it when needed won't have a big impact on flow, or
do lots of joints and corners seriously slow things up?
Recommendations for a reliable and reasonably powerful shower pump?
(Not done one before)
