WELCOME TO YOUR THERMAL
STORAGE SYSTEM
BOILERMATE A-CLASS - THE POWER
BEHIND YOUR DOMESTIC HOT WATER
AND CENTRAL HEATING
The hot water and central heating in your
home is provided by a high specification
thermal storage system coupled to a boiler
which may be gas or oil. It should give you
many benefits which will be explained
in this leaflet. It is simple to operate and
exceptionally efficient and is probably
different to water heating systems that you
have had previously.
The Gledhill BoilerMate A-Class offers four
major advantages:
The storage vessel is designed with
an electric emergency back-up for
HEATING AND HOT WATER called
‘Switch’ which should be activated in the
event that the boiler fails. You should
familiarise yourself with the emergency
system when you occupy the property
so that you know it is available and how
it works should it ever be needed.
Delivers lots of hot water at good
pressures whenever you need it.
It will supply heating and powerful hot
water more efficiently than conventional
systems.
It eliminates the traditional cold water
and heating tank in the loft and therefore
removes the risk of contamination and/
or freezing.

It is important that if the boiler has a
temperature control this should be
left at its maximum for the system to
operate efficiently.
Your central heating times are controlled
by the central heating control rocker and
timer which in most cases is fitted to
the front panel of your BoilerMate. The
rocker provides you with the option of
having your central heating on constant,
timed, or off. When the rocker is on the
timed position the timer can be set to
suit your individual requirements. This
is the normal/recommended method
of operating your central heating. The
temperature in your house is set by a
room thermostat/thermostatic radiator
valves and these should be adjusted to
suit your individual requirements.
Your hot water is controlled by the hot
water rocker and timer which in most
cases is fitted to the front panel of your
BoilerMate. The rocker provides you
with the option of choosing constant,
timed, or off. When the rocker is in the
timed position the BoilerMate will only
be heated at the times set on the timer.
For this reason we would normally
recommend that the rocker is set in
the constant position. The BoilerMate
is extremely well insulated and the
standing loss is minimal and the boiler
will ONLY fire to meet your need for hot
water or heating.

The operation of ‘Switch’ is explained on
pages 8 and 9. It can be set for hot water
only or hot water and central heating
dependant on the time of year. It does cost
more than gas to operate in this way which
is why it is recommended that it should
only be used in an emergency until the
operation of the boiler is restored.

WHAT IS A THERMAL STORE ?
The Gledhill Thermal Store is the heart and
brain of your central heating system. It
stores hot water at a constant temperature
and incorporates a highly efficient plate
heat exchanger which heats the hot water
for all your domestic needs. The Thermal
Store is superbly insulated and so the hot
water stored has a very low heat loss. It also
incorporates an intelligent sensor which
determines when the temperature drops
below a preset level required for optimum
efficiency. When that temperature drop
is detected, the Thermal Store instructs
your domestic boiler to fire provided the
timeclock is in an “on” period, generating
the additional hot water needed to top up
the store temperature. When the required
temperature is reached, the boiler stops
firing, until the next time it is required.

WHY SHOULD THE BOILER THERMOSTAT
BE SET TO MAXIMUM?
The system operates most efficiently
if the boiler is always left with the
thermostat at its maximum setting
- even in summer. This is because the
intelligent electronics within the Thermal
Store control the store temperature
automatically. Your system should,
generally, be left ‘on’ if you are away for
a short period. The room thermostat can
be set to a low level just to prevent frost
damage to your domestic pipe work
systems if you wish.
HOW DOES THE SYSTEM DELIVER
WATER AT HIGH PRESSURE?
The water to the taps and showers in
your home is delivered at high pressure
because it uses the mains pressure of
your cold water supply. The BoilerMate
A-Class is connected to the mains
system and the water passes through a
highly efficient heat exchanger to raise
its temperature before it travels to your
taps and showers.
Because it is so efficient, both high flow
rates and high pressures are available
to give the best performance for both
baths and showers.

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.

CONTROLLING YOUR BOILERMATE
A-CLASS
Your BoilerMate is a highly advanced
Thermal Storage System which incorporates
the latest in microprocessor technology to
monitor your system automatically and
ensure it operates at maximum efficiency.
This includes periodically ‘spinning’ the
heating pump to prevent seizing during
prolonged unused heating periods.
In normal circumstances, you should only
be required to adjust the time clock on
your Thermal Store, to suit your needs, and
the instructions for this are described in
detail on the label fitted to the appliance.
If your hot water or heating system should
fail to operate satisfactorily, you will need
to operate the ‘SWITCH’ option which is
fitted to your BoilerMate A-Class. [See
‘Switch’ at the back of this booklet] and
then call a service engineer, who can then
contact Gledhill Technical Department for
any advice he may need
As detailed previously, in order to ensure
your system operates at its most efficient
the boiler thermostat should always be
left at maximum.
* If you have your hot water rocker set to
timed and you wish to draw a considerable
quantity of hot water you will get an
enhanced performance from your thermal
store by setting your time clock to bring
the system on 20 minutes before you want
to draw the hot water.

USI NG THE UNI QU E ‘ S WI TC H’
EMERGENCY ELECTRICAL BACK-UP
SYSTEM
Your BoilerMate A-Class is fitted with
Gledhill’s unique ‘SWITCH’ emergency
electrical back-up system. You have an
instant failsafe should your boiler cease to
operate. The ‘SWITCH’ system will be clearly
displayed on the front of your Thermal
Store Appliance.
In the event of a boiler failure follow the
instructions left by the boiler manufacturer.
If you are unable to restore heating and
hot water activate the ‘Switch’ and call
the boiler service engineer. ‘SWITCH’
technology simply and instantly introduces
an electric heating source within the
Thermal Store to ensure that your hot
water and heating continue to operate at
reduced performance until you can have
your boiler repaired.

RESETTING THE HEATING/HOT
WATER PROGRAMME CLOCK
This is used in conjunction with the central
heating and hot water rockers to choose
how and when these systems operate.
Separate instructions for this will have been
left for you by the installation engineer, or
you can refer to the instructions on the
label on the front of the appliance.
