SECURE ORDER
TO FAST DELIVERY
THE COMPLETE BESPOKE
CYLINDER SERVICE
FOR MANY YEARS, WE HAVE BEEN WELL KNOWN IN
THE INDUSTRY FOR OUR CAPABILITY TO PRODUCE
COPPER CYLINDERS TO CUSTOM SPECIFICATIONS.
The versatility of copper makes it the perfect choice of material to produce bespoke,
tailor-made cylinders that can be manufactured locally in a fast turnaround time. This
has led to high demand, particularly for bespoke orders and one-off specials, that can
be custom-made in just a matter of hours.
The buoyant demand for copper specials comes from a wide range of installations;
from matching the exact specification of an old domestic cylinder that needs
replacing, to creating a horizontal boiler to fit into the confined space of an attic.
Cylinder sizes can range from a 45-litre cylinder for use on pleasure boats,
to a 960-litre industrial-sized model for use in commercial premises.
These cylinders are all manufactured in compliance with BS1566 and comply
with 2010 Part L1B Building Regulations Replacement Cylinder requirements.

WHAT ELSE DO YOU NEED TO
CONSIDER WHEN ORDERING A
GLEDHILL CYLINDER?
GRADES OF CYLINDER
There are three ‘grades’ of vented cylinder G1, G2,
G3. All are built to the same manufacturing standard,
the principle difference between the three grades is
the gauge of the copper sheet used. To determine
the grade required measure the distance from the
waterline in the header (or feed and expansion) tank
serving the cylinder and the base of the cylinder. This
measurement is known as the ‘working head’ and
determines the grade of cylinder to be used.
GRAVITY COIL
When ordering your Gledhill cylinder, you would
need to specify if it requires a gravity coil. This is
where the hot water circulation is attained by using
the natural convection current rather than by the use
of a circulation pump to ‘force’ the water around the
system. The main difference in the cylinder design
between a pumped and gravity circulation system
is that the connections/coils are larger in the gravity
systems to provide less resistance and increase the
flow rate.

The quick recovery cylinder has a special high
performance heat exchanger which reduces boiler
cycling and maximises the time the boiler can
operate in condensing mode.
Its special coil enables recovery in as little as
five minutes, assuming a correctly sized boiler
is installed.
The reduction in boiler cycling and faster recovery
time combine to reduce the cost of producing hot
water.
The super recovery cylinder’s high efficiency coil
and its ability to heat only the water you require
means that a smaller capacity cylinder can be used.
This makes it the ideal replacement choice where
space is an issue but rapid reheat times are still
required.
The cylinders 35mm of high insulation EnviroFoam
further reduces standing losses – particularly
beneficial during summer months.

The EnviroFoam Copper cylinders are also
available with a special high performance heat
exchanger, on request, which reduces boiler
cycling and maximises the time the boiler
can operate in condensing mode. These were
previously known as our CondenCyl range.
The special coil enables recovery in only 14 minutes
which conforms to CHESS best practice. The
reduction in boiler cycling and faster recovery time
combine to reduce the cost of producing hot water.
The high efficiency coil and its ability to heat only
the water you require means that a smaller capacity
cylinder can be used. For example, a typical 120
litre cylinder to meet Part L1B requirements would
reduce to 80 litres using a high recovery coil.
Utilising the EnviroFoam insulation reduces
standing losses – particularly beneficial during
summer months.

A thermal store provides the perfect solution to
a home’s heating and hot water requirements.
Torrent ECO offers more options than any other
store or cylinder, and is designed to reduce
heating costs by offering complete flexibility for
householders to use multiple energy sources.
The Torrent ECO enables the hot water within
the store to circulate around the heating
system to provide heat to the property, with
the domestic hot water being mains cold water
instantaneously heated through a plate heat
exchanger.
Thermal stores provide many additional
benefits including:
• Mains pressure hot water
• No annual maintenance or safety check
requirement
• No discharge pipework
• No risk of legionella
• Inherently safe being an open vented cylinder
• No G3 qualification requirement for
installation
The Torrent ECO is manufactured from copper,
by our trained coppersmiths, within Gledhill’s
eight nationwide manufacturing depots.
This provides the flexibility for homeowners
to select the thermal store which best suits
their requirements, allowing them to maximise
the available heat sources, whether they are
traditional boilers, electric immersions, or
increasingly popular alternative energy
fuel sources.
The cylinder is open vented, enabling
uncontrolled heat sources such as
woodburning stoves to be used.
LEGIONELLA
& SCALD PROTECTION
The domestic hot water is generated by mains
cold water being instantaneously heated as it
passes through the heat exchanger, which is then
delivered to the taps. This method of generating
the hot water completely removes the risk of
legionella. Gledhill’s patented intelligent controls,
in conjunction with the sensors, regulate the
temperatures being delivered to the taps or
shower, preventing the risk of scalding.
The SunSpeed is an open vented cylinder which
makes the location of the cylinder more flexible
because the cylinder does not require a safety
discharge pipe.
The SunSpeed cylinders are insulated using
35mm HCFC free EnviroFoam to comply
with Part L of the Building Regulations. This
insulation incorporates Polyol which is derived
from rapeseed oil - a fully renewable resource,
with an industry leading Global Warming
Potential of 0.7. It also provides exceptionally
low standing heat loss.
For more information
on the Torrent ECO range, and the options available, please refer to the separate brochure.

SunSpeed is a domestic hot water cylinder
designed for use with solar panels. It is a
copper cylinder with two heat exchangers,
one for solar input and one for a boiler input.
The dedicated solar volumes range from
34% to 49% with the majority exceeding 40%
enabling the best use of the solar panels. These
dedicated solar volumes allow maximum
suitable solar panels surface area from 2.9m
2
to 5.0m
2
. The surface area of the solar heat
exchanger coil is designed to exceed Building
Regulations requirements.
The boiler coil comes into play in the cooler
months of the year as the solar input
diminishes. A correctly sized cylinder will
ensure enough hot water is available to the
householder during these months as the
dedicated solar volume will not be heated by
the boiler. The boiler coil is sized appropriately
to the cylinder and gives a recovery time of
less than 26 minutes with sizes to meet all
regulations.

The twin coil cylinders are designed to be used
with two heat sources, including uncontrolled
heat sources such as solid fuel (e.g. an Aga stove)
alongside a conventional gas or electric boiler.
To boost the efficiency, an optional high recovery
coil is available.
The cylinders are available in all three grades, which
need to be specified at the time of ordering, and
are available in bespoke size and specifications.
All the cylinders are 2017 ErP compliant and come
with a 10 year warranty.
Compression fittings are available on these
cylinders, but will need to be specified when
ordering.
Where the height of a room restricts the
installation of a standard cylinder, then a
horizontal cylinder may well be the answer.
These are particularly suited to confined
loft spaces and are available either as direct
or indirect, which can also be supplied with
support cradles.
These units provide a highly effective and
efficient means of providing and storing hot
water where headroom is at a premium.
A twin coil configuration can be specified when
ordering, to utilise solar power or a solid fuel
boiler in conjunction with a conventional boiler.

industrial applications.
Calorifiers are available as standard patterns,
horizontal or vertical or high performance
‘Heatspeed’ types. All are manufactured from
copper, long recognised as the best material for
water storage vessels giving the longest life.
The direct pattern is ideal where the only
heatsource is electricity, although these can also be
made to incorporate a solar coil where a solar input
is also available.
The indirect patterns are either 1 or 2 hour recovery
as standard, but can be specified for a 30 minute
recovery when ordering. These can also be used
with solar or solid fuel inputs. Extra tappings or coils
are also available to run underfloor heating from.
Capacities can range up to 1000 litres and products
are individually made to order to accommodate
connections and heat exchangers to suit individual
applications.
A full range of extras including bolted heads,
inspection ports, hand holes and cradles are
available if required. Systems with high draw rate
potential over extended periods are best served by
units with high recovery capability and moderate
storage capacity for balancing purposes.

The combination tanks are supplied in direct
and indirect configurations. Both types of
unit provide gravity fed hot water and can be
installed at high level in a cupboard or in a roof
space. The indirect model can also be used on
pumped and sealed systems.
The direct model is designed for use with all off-
peak tariffs, the thermal properties of the HCFC
free insulation ensure low energy costs to the
consumer. The direct combination tank ensures a
fast, simple installation that will save money, time
and materials, and can be supplied fitted with two
3kW immersion heaters and thermostats to make
installation even quicker.
Even with future changes to the heating
installation the indirect combination tank would
not require replacing. For example, should the
heating system be changed from open vented
to a sealed primary circuit it can be adapted by
simply blanking off the primary cold feed and
primary vent connections.
Figure 1 shows a hot water store designed for
use with electric.
Figure 2 shows a hot water store designed to be
used with a sealed system or it can be used with
a separate F&E tank for a fully pumped system.
