I've just moved home which has a power shower fed by a Newteam Varispeed
sited in our airing cupboard ... the pump is rated at 245Watts 5000rpm
1.5bar. While it is an adequate shower (in terms of flow rate ... I have
not measured it) it does not seem that great for a power shower (this is my
first!). My main concern is the noise and vibration it causes. We live in
a modern house and the noise and vibration seems to pass all over. It is
very very noisy ... probably as loud as a vaccum cleaner. We have no chance
of taking a quick shower before my 2yr old wakes in the morning!!
After doing some research, I have decided that i'll probably replace it with
a Stuart Turner pump. I suppose my question is, can I expect this to be
much quieter? I am considering two models ... the Monsoon1.5 bar and the
Monsoon 3.0 bar. Will there be much of a difference in the noise between
the two? I am leaning towards the 3 bar model because I may fit another
shower in my main bathroom (some time in the future) and would like to power
this from the same pump. However, I dont want to overkill especially if it
means more noise!
Any feedback greatly appreciated.
Depending on your budget, a much more expensive solution that would easily
provide enough for your showers with no noise at all would be to replace
your current gravity fed hot water cylinder with either an unvented cylinder
(i.e. Heatrae Megaflo) or heat bank (i.e. DPS Pandora). Although this will
cost several times the cost of the pump, it will provide power shower
performance at all outlets. The Pandora is easily fitted, requiring the same
skills as fitting the pump, but with more to do. The Megaflo is much less
easy to fit, but provides even greater potential flow. All of this is
provided your mains water flow and pressure is sufficiently good to be worth
Obviously, the pump is the easier, quicker and cheaper solution. However, if
your hot water cylinder is an old grade 4 nearing the end of its life
anyway, or is insulated with only one of those jackets, then it could even
make economic sense.
As for the performance of the shower, with almost any shower pump, the
limiting factor on flow rate will be the shower head and hose, (or possibly
the mixer). Remove any flow rate limiting inserts and ensure you have a hose
and head designed for power showers.
How do you keep your 2yr old asleep long enough to have a shower?!
We had a Newteam power shower pump in our previous house and the noise
was objectionable. They are the cheapest of the cheap so I would expect
the more expensive pumps to be quieter. I eventually stood our pump on a
piece of MDF supported by a large foam block which did reduce the
transmitted vibration, though not the actual noise.
