StainlessLite

Gledhill - The Cylinder SpecialistThe Gledhill name is synonymous with a family of water

heating and storage products that lead the field in terms

of innovation and quality. We are respected for our world-

leading range of primary stores, but we have also produced

unvented cylinders from the very beginning. Stainless Lite is

an unvented mains pressure store in Duplex stainless steel

that establishes new criteria for quality, performance and

life.

Providing powerful, mains-pressure performance, it

incorporates high flow rate controls, ideal for multi bathroom

homes where baths fill very quickly.

There are Indirect and Direct patterns for gas/oil and

electricity with model sizes from 60 litres to 400 litres in each

pattern with an additional eight options for solar energy.

Duplex Stainless SteelThe Stainless Lite uses the very latest high specification

Duplex to resist all forms of corrosion including crevice and

stress whilst its high mechanical strength gives it durability.

The very latest automated welding procedures along with

full post weld treatments guarantee welds that are as strong

as the parent metal. Stainless Lite is pressure tested in

the factory to a full 12 bar which is four times the normal

working pressure.

Corrugated CoilStainless Lite uses a high heat transfer corrugated tube heat

exchanger to give a 20% faster recovery than plain tube. It is

also lighter and stronger than plain tube making the vessel

the lightest and easiest to handle on site.

Heat LossAll Gledhill Stainless Lite cylinders are manufactured using

the very latest HCFC free EnviroFoam insulation. This has

an Ozone Depletion Potential (ODP) of zero and an industry

leading Global Warming Potential (GWP) of 0.7.

Tests show that the 50mm of EnviroFoam insulation

injected into the case and covering both domes achieves

astonishingly low levels of heat loss, which ensures it is fully

compliant with 2010 Part L requirements for both new build

and replacement cylinders.

25 Year GuaranteeThe 25 year guarantee underlines the usual Gledhill

confidence in its own products. We regularly have copper

cylinders returned to us that we made more than 40 years

ago – why should anyone expect less from stainless steel?

ServiceBuying a good reputable product is critical – but it must be

available when needed. Gledhill has strategically located

manufacturing units so that delivery can be made to a

merchant anywhere within hours.

Quality Standard - EN 12897All Stainless Lite cylinders are manufactured in accordance

with BS EN 12897 the specification for unvented water

Gledhill Building Products manufacture 16 standard direct

and indirect cylinders, ranging from 90 litres to 400 litres

capacity.

The Stainless Lite direct model is supplied with two

immersions for off-peak and on-peak use (except 90 litre

model which only has an on-peak immersion). Therefore,

the store of water in the cylinder can be heated utilising

the off-peak electricity, making the unit extremely efficient.

These cylinders are ultimately lightweight, easy to install

answer for electric hot water options.

The immersion heater(s) must be connected to the supply

through a double pole linked isolating switch with a

minimum breaking capacity of 13A.

All models have a temperature and pressure relief valve

factory set at 6 bar and 92-95°C.

The indirect range has a high efficiency corrugated tube

coil which is connected to a conventional boiler to heat

the cylinder of water. The coils corrugated design gives

you much faster re-heat times than can be achieved with

plain tube coils. All indirect models come with an on-peak

immersion but only the 250, 300 and 400 litre models are

supplied with an off-peak immersion.

All tappings are within a 90˚segment to make installation

easier.

solar panel to ensure compliance with Building Regulations.6 Maximum solar panel area is calculated based on 25l/m2 of net solar panel area.

Gledhill has developed a range of cylinders specifically for solar

applications in mind, therefore providing an efficient way of

providing domestic hot water. Each model features a dedicated

high performance solar coil, transferring the maximum amount

of heat from the solar circuit to the stored water. The cylinders

are compatible with a wide range of solar systems available

through the United Kingdom and have been designed to

maximise the dedicated solar volume.

The direct models are electrically heated cylinders, using

the 3kW immersion heater supplied with the unit, with a

high performance solar coil. They are capable of meeting

the requirements of Building regulations, provided that it is

matched to the panels and the hot water requirement correctly.

The indirect cylinders are heated by a conventional boiler

(either gas or oil) through a second high performance coil.

The solar range is based on the standard Stainless Lite

cylinders, therefore still providing you with mains pressure

hot water, low standing heat losses and lightweight

construction. The range of cylinders is suitable for properties

from a bedsit to a 5 bedroom family home.

StainlessLite SlimlineUnvented cylinders designed for restricted spaces with optional solar coil

The new Stainless Lite Slimline cylinders have been added

to our range of Duplex stainless steel cylinders, to enable

you to utilise those smaller storage areas.

The standard size Stainless Lite cylinders are 550mm

in diameter but the new slimline range has a reduced

diameter of 475mm.This now enables installers to fit the new

cylinders into smaller properties or older homes where there

are space limitations, and so provide the benefits of mains

pressure hot water.

The new range of Stainless Lite Slimline cylinders come in

sizes from 60 litres to 210 litres in both indirect and direct

versions. In addition, it also comes with a solar option in

180 litre and 210 litre sizes. This now means there will be a

model to suit most homes.

The introduction of the Slimline solar range enables

homeowners to not only upgrade to a Duplex stainless steel

cylinder, but also have the added benefit of being able to

utilise solar power to contribute to the heating of the store.

Properties that previously could not enjoy mains pressure

hot water can now enjoy powerful, mains-pressure

performance, incorporating high flow rate controls, ideal for

multi bathroom homes, where baths fill very quickly.

You will still benefit from the high heat transfer corrugated

tube giving 20% faster recovery than plain tubing, controlled

stratification and minimal heat loss.

All slimline models (except 60 and 90 litre direct options)

come complete with an on-peak immersion. All direct

models have an off-peak immersion.

StainlessLite HPStainless steel unvented cylinder designed for use with heat pumps

Gledhill have expanded its range of unvented stainless steel

units specifically for heat pump applications by developing

a model with an increased size heat exchanger to maximise

the lower temperatures available from the heat pump.

The heat exchanger is a new design, and has been

increased up to 4 square metres in the largest units,

maximising the heat exchange.

Due to the fact that many heat pumps will not raise the

stored water temperature to 60˚C, which is necessary to

prevent the growth of legionella, the Stainless Lite HP model

is supplied with an immersion heater and a thermostat. It

is recommended that a thermostat is fitted which brings the

immersion heater ‘on’ at a temperature just below the heat

pump maximum and switches off at 60˚C or 65˚C.

StainlessLite HP SOLUnvented cylinders designed for use with heat pump and solar technology

Gledhill have produced an unvented stainless steel unit

specifically for heat pump applications providing mains

pressure domestic hot water. Utilising the well established

Gledhill Stainless Lite unvented hot water cylinder, this

product has been developed to maximise the lower

temperatures available from the heat pump.

The heat exchanger is a totally new design. It consists

of a multi-pass corrugated stainless steel tube in parallel

to reduce the pressure loss whilst maximising the heat

exchange. Many medium to large heat pumps need heat

exchangers in the store that will cope with the higher flow

rates associated with primary temperatures that are typically

50˚C or 60˚C.

All the usual features of the Gledhill Stainless Lite are

maintained together with all the necessary controls and

expansion devices included.



prevent the growth of legionella, the Stainless Lite HP model

is supplied with an immersion heater and a thermostat.

It is recommended that a thermostat is fitted which brings the


pump maximum and switches off at 60˚C or 65˚C. In this

way the use of ‘direct’ electricity is minimised and most of the

water heating is achieved through the heat pump.

The key features of the Stainless Lite HP SOL are:

• The latest and highest quality Duplex Stainless Steel.

• A 25 year guarantee.

• Fast reheat rate from its purpose designed low

resistance coil.

• One of the highest insulation ratings on offer today.

• The Stainless Lite HP SOL is supplied with all the

necessary connections including two dry thermostat

pockets.

Slimline Heat PumpStainless steel unvented heat pump cylinders designed for restricted spaces

In situations where you want to upgrade a standard cylinder

with a heat pump installation, you will constantly come up

against the problem of installing a standard diameter unit

into a small cupboard space, common in older properties.

As a result, in addition to our existing Stainless Lite standard

heat pump range, we have developed the new Stainless Lite

Slimline HP which has a reduced diameter of 475mm.This

now enables installers to fit the new cylinders into smaller

properties or older homes where there are space limitations,

and so provide the benefits of mains pressure hot water.

The new range of Stainless Lite Slimline HP cylinders come

in 180 litres and 210 litres sizes.

Utilising the well established Gledhill Stainless Lite unvented

hot water cylinder, this product has been developed to

maximise lower temperatures available from the heat pump.

Although the cylinder has a reduced diameter, it still has

a 3m2 high performance corrugated coil which has been

specifically designed for maximum heat transfer. The heat

exchanger is a totally new design. It consists of a multi-

pass corrugated stainless steel tube in parallel to reduce

the pressure loss whilst maximising the heat exchange and

ensuring high flow rates essential to work with heat pumps.



prevent the growth of legionella, the Stainless Lite Slimline

HP model is supplied with an immersion heater and a

thermostat.

It is recommended that a thermostat is fitted which brings the


pump maximum and switches off at 60˚C or 65˚C. In this

way the use of ‘direct’ electricity is minimised and most of the

water heating is achieved through the heat pump.

Buffer StoreVented store for use with heat pump systems

Buffer vessels are simply a duplex stainless steel tank that

contains a volume of water, increasing the overall volume of

the heating distribution system. This extra volume of water

is designed to absorb any extra heat generated by the heat

pump in low load conditions.

If the building cannot absorb the extra heat generated

the return temperature to the heat pump will increase

and will potentially cause the heat pump to turn off. If the

temperature drops in the water returning to the heating

appliance, then it will turn itself back on. If this cycling

occurs at a greater frequency than the minimum run time for

the appliance, this is classed as short cycling. The aim of a

buffer vessel is to remove the possibility of any short cycling

of the heating appliance.

These buffer vessels are designed to work at up to 3.5 bar

pressure for primary water only. They should not be used

for potable domestic hot water and are not approved for this

purpose.

The Buffer Store range has been extended providing

multiple connections. This not overcomes the issue of

connecting multiple heat pump units to a single store, but

you are now also able to connect a wood burning stove

and open vented gas boiler (subject to correct controls

being installed), making the Flexible Buffer Store the perfect

solution. This allows you to utilise multiple heat sources to

boost the temperature of the water within the store initially

generated by the heat pumps.

In addition to the multiple inputs, the Flexible Buffer Store

also allows installers to connect a heating circuit to the

cylinder to provide heating to the property.

These buffer vessels are designed to work at up to 3.5 bar

pressure for primary water only. They should not be used

for potable domestic hot water and are not approved for this

purpose.

To satisfy the growing demand for a stainless steel cylinder

being capable of accepting multiple heat sources, Gledhill

has developed a triple coil version of the Stainless Lite

cylinder, which can accept solar and uncontrolled heat

sources such as solid fuel or wood burning appliances.

The cylinder has a dedicated solar coil at the bottom of

the cylinder. It then has a double coil for the solid fuel heat

supply and a single coil for the gas/oil boiler. It also has a

back up heat source in the form of an immersion heater.

The three separate coils will work independently providing

the maximum heat to the store, and subsequently reduce

the households fuel bills. The boiler coil and solar coil are

both 22mm and the solid fuel gravity circulation are 28mm.

StainlessLite VentedUnvented cylinders converted for use with uncontrolled heat sources

The only difference between the vented and unvented range

of Stainless Lite cylinders is that instead of being supplied

with the unvented kit, the vented option is supplied with a

control thermostat and a drain valve.

The technical and dimensional data for the Stainless Lite

vented is the same as the Stainless Lite and Stainless Lite

Solar, both of which are available in direct and indirect

configurations. Full technical details can be found on pages

5-8 in this brochure.

The Stainless Lite vented option provides a high quality

open vented stainless steel cylinder for use in a traditional

vented cylinder installation. As an open vented cylinder, it

also permits the connection of an uncontrolled heat source

such as a solid fuel or wood burning appliance, which is not

permitted with an unvented cylinder. Please note when using

in this application, a fully pumped system will be required.

The traditional vented storage water heater has a proven

track record of reliability and safety. The operating pressure

is dictated by the vertical distance between the cistern tank

and the bottom of the heater.

The open vented system is renowned for its safety because

the open vent that discharges in to the cistern tank

automatically equalises any excess pressure or vacuum.

The Stainless Lite vented cylinder is fully compliant with

2010 Part L regulations, therefore it now enables you to fit a

vented cylinder into a new build property.
