WHY ARE THERE NO WATER CISTERNS
IN THE LOFT?
Because the Gledhill system uses the
pressure from your cold water mains,
these cisterns are not required, which
removes any worries about freezing or
contamination of the cold water system
from insects, dust, birds etc and leaves
more space for storage should you
decide to use it.
Depending on the height of your
airing cupboard it occasionally may
be necessary to position the small
expansion tank,for the BoilerMate itself,
within the loft space e.g. in bungalows.
However, normally the BoilerMate
A-Class SP own feed and expansion
cistern is fitted in the same cupboard
as the appliance and is filled manually
when the appliance is first installed. It is
beneficial to check and if necessary top
up the water in this cistern during the
annual boiler service or if the appliance
is not producing hot water.
Your heating system is also filled
manually from the cold water system
by means of a temporary filling loop.
The pressure should be at 1.0 bar when
the system is cold and will rise by about
0.5 to 1.0 bar (ie to between 1.5 and
2.0 bar), dependant on the size of the
system, when fully hot. The system and
expansion vessel pressures should be
checked and topped up at the annual
boiler service or if the heating system
fails.
