Shower Information
The Medway Super and Thames will work in conjunction
with many modern showers or bath/shower mixers.
The
Mersey Super is not suitable for use with a shower
system
.
Shower systems fed with an instantaneous water heater
may result in a decreased temperature range and
adjustment facility when compared with shower systems
fed from storage systems although in general a
satisfactory shower can be obtained with both manual
and thermostatic type mixer valves.
Some manufacturers supply shower systems suitable for
use with instantaneous water heaters and give specific
instructions for installation and use. In these instances
preference should be given to the shower manufacturers
instructions.
For further information regarding shower systems
contact the following manufacturers quoting the make
1. Most instantaneous water heaters are
capable of supplying several outlets, but not
necessarily at the same time.
2. To obtain the best results from the shower
system the Dereve Water (Pressure)
Governor type 7052/4 should be installed to
govern the cold supply to the shower.
For local suppliers of the governor contact:
Dereve (Flow Controls) Limited,
Park Lane,
Handsworth,
Birmingham. B21 8LE.
Tel: +44 (0)121 553 7021.
Some mixer valves may not require the
fitting of a water governor, advice must be
sought from the shower manufacturer.
3. The nearer the shower is to the water heater,
the more satisfactory will be the shower,
particularly ease of temperature selection.
4. Ideally the cold water pipes on the delivery
(outlet) side of the water governor to the
shower should not serve any other draw-off
when the shower is in use.
5. If the shower is permanently too cold
unscrew the water governor slightly, if the
shower is permanently too hot screw the
governor in slightly until a reasonable range
is achieved.
