are transforming the way we specify, install and use hot water in the home...

THE STORY BEHIND

THE DEVELOPMENTS

The copper hot water storage vessel where hot water is stored for distribution round the home, traditionally located in the airing cupboard, is still the key to a successful hot water supply.

IT’S HISTORY GOES A LONG

WAY BACK

Until the mid 1980’s, virtually every house in

Great Britain had a storage system to provide hot water. Typically, it used a copper cylinder, located in the airing cupboard, heated by a central heating boiler or a coal fire!

The primary water was passed through a heat exchanger in the cylinder and pressure for showers relied on

‘head’ from the cold cistern. This traditional concept began to change from the late

1970’s onwards, mainly because of the growth in gas central heating, a new awareness of showers, the introduction of mains pressure hot water systems and particularly with the launch of combi boilers.

The wall hung combi was designed to provide both space heating and mains pressure hot water at the tap. The problem with the combi is that, generally, it has little or no storage and can only raise the water temperature by a fixed amount, typically 43°C. So, in the summer when the cold water temperature is, say 12°C then output is 55°C but in the winter when the cold water mains is as low as 2°C, hot water output only rises to 45°C.

This falls far below a hot water storage system performance where there is a ready to use store of hot water that can be set at a thermostatically constant temperature, typically

60 - 65°C, regardless of outside temperatures.

This means that it can be blended down to a comfortable, usable temperature which gives a greatly increased volume of hot water available for use in the home.

THE FACT IS THAT HOT WATER

STORAGE SYSTEMS ARE STILL

UNBEATABLE!

And this fact is not affected by the variable pressure or flow found in the supply conditions that occur more and more today.

RANGE

GO

ONE BETTER

Knowing that a storage hot water system was still the best system available, Range set about improving them to satisfy the demands of not only consumers but specifiers and installers alike.

This meant developing designs to match modern central heating boiler efficiencies, designs that would give systems longer life and innovations that make products simpler to install and maintain.

Range also needed to demonstrate the difference between their high quality new design products from those that might already be installed in established properties. Inferior design medium duty type cylinders that have been there for many years and which can be recognised by their lagging jacket or pale green urethane foam insulation. And so that these ‘market leading’ developments are clear, Range changed the colour of their products to a unique and distinctive blue.

INNOVATIVE CRT FOR COPPER

PRODUCTS

In recent times, the problem of Pitting Corrosion has been affecting many more areas of the country. On top of this, a new danger - Rossette Corrosion has been discovered.

All this prompted Range to take a long, hard look at the basic design of hot water cylinders. The result was CRT -

Corrosion Resistant Technology.

KERNEL PLUMBING UNITS

Compact, factory built and tested plumbing units designed to provide easy on-site installation on both direct and indirect heating systems. These units are extensively used in both new build and modernisation work saving time money and mistakes on site.

FORTIC COMBINATION UNITS

Fortic combination units comprise a cold water cistern and hot water cylinder into a single unit of all copper construction.

They can incorporate CRT technology, a choice of performance levels and can affect installation cost savings by eliminating most of the ancillary plumbing associated with other types of storage systems.

They are an effective way to provide an adequate hot water service from a confined space and are ideal for flats and modernisation schemes.

CHOOSING THE RANGE

SYSTEM TO SUIT YOU

When you choose RANGE you’re getting today’s most exciting new products. And much, much more.

Range is the UK leader in hot water storage, with the biggest nationwide distribution and product availability. You won’t find more competitive prices and the quality is unbeatable.

British Standard is the minimum standard and most models exceed this in terms of both manufacture and performance.

IT’S HISTORY GOES A LONG

WAY BACK

The information below is a general guide for selecting the correct size of cylinder for use in domestic applications.

If you are in any doubt or have a more specialist application such as a nursing home, sports centre or youth hostel please ring us.

BS 6700 (1997) covers cylinder selection in detail.

The following are two main factors to take into account.

1. The storage volume required to meet peak demand.

Typical hot water demand (litres of water at 60°C.)

Standard bath 60 litres

Corner bath

Shower

Power shower

Wash basins

Kitchen sink

120 litres

30 litres

60 litres

5 litres

15 litres

2. How quickly can the energy source reheat the water.

With gas or oil boilers fast recovery cylinders such as

Ultracal, can help you to achieve quicker reheats and reduce the amount of water that needs to be stored.

When off- peak electricity (Economy 7/10) is used for water heating, it is most economical to heat the total contents of the cylinder overnight. This reduces the need to use immersion heaters boost periods during the day when electricity is more expensive.

Super Seven cylinders, which meet the Maxistore specifications are recommended for all electric applications.

Installation of solar cylinders can now be grant assisted.

30% of the volume is dedicated solar capacity, and 70% volume can be heated in the normal way via a primary coil on days when solar input is not sufficient to heat the full contents of the unit or on days when additional energy is required.

Two control thermostats are used to maximise solar gain. The upper one is used for boiler control (not supplied). The lower one is for solar control (not supplied). The upper 1/2” female boss (G) is for a temperature gauge

(not supplied).

The range shows seven popular sizes and capacities. When calculating the size required, please ensure that the upper coil volume is used for total requirement. If the application is for a twin bath, for example, at least

145 litre of ‘upper coil’ volume is required so that this demand can be catered for on winter days.

The range shown here has a Part L complaint upper coil fitted.

The Solarmax coil can also be used for geotherm or alternative fuel input.

DUBLO 100

The Dublo 100 has a maximum working head of 30 metres, i.e.100 ft.

It is suitable for use in single or multiple dwelling applications, and is designed with three main purposes in view:

• To be highly efficient

• To withstand high working heads

• To be very compact

In practical use these objectives have been successfully achieved and the space saving feature has proved especially valuable in the compact plumbing layouts which are now generally favoured, as well as being ideal for conversion and modernisation programmes where their narrow form and highly effective insulation permits their use in shallow recesses.

Operation

The cold water enters through the disperser, and slowly fills the lower portions of both cylinders in proportion to the amount of hot water being drawn off, at high draw - off rates.

The metering orifices at the top and the bottom ensure that an equal amount is provided by each cylinder.

It will be noted that, owing to the small diameter of each unit, there is no likelihood of the incoming cold water mixing over a large area with the hot, thus reducing the temperature and this effectively ensures that almost all the stored hot water is available for use.

The Dublotank operates on the

‘U’ tube principle, i.e. the cold water being heavier than the hot, it will always balance the hot water in both halves of the unit, whether or not hot water is being drawn off.

The expansion pipe on the top draws equally from both halves for the unit whilst the breaching connection to the bottom of both halves obviates any ‘dead water’. Units are supported by an integral steel skirt.

Immersion Heaters

If a vertical immersion heater is fitted, the recommended maximum length, when used in the top entry position, to obtain maximum quantity of heated water, should be 150mm less than the overall height of the unit

(shown on diagrams at ‘A’).

This applies to all models whether

Direct Pattern, Single or Double

Feed Indirect Pattern.

The advantage of the vertical heater is that hot water is available quickly, but it requires access above the Dublotank if it should need to be removed.

Where a horizontal Immersion heater is chosen a 230mm heater should be used.

VENTED HOT & COLD WATER STORAGE

FORTIC DIRECT

FORTIC F1 SUPER SEVEN

A british standard 3198 direct combination cylinder manufactured to the

Maxistore specification.

Fast Reheat Option

Fortic combination units can be specified with Supercal or Ultracal coils on request for faster reheat.

Cold Section

The correct height for fitting the float operated valve (Ball valve) and warning pipe connection (overflow) is marked on the cisterns of all units.

All units are supplied with a rigid type lid which closely fits the rolled rim of the cistern.

An overflow, frost guard and air vent kit complete with corrosion resistant mesh screens are enclosed within the cold section for fitting on site.

These standard features ensure the unit fully complies both with BS 3198 and Water

Supply Byelaw 30 requirements.

The insulation of the division between hot and cold water sections ensures that heat transference is minimal and it meets the requirement of the British Standard.

Cold water capacities are measured to the water level marking. Hot water capacities are based on direct units.

Indirect units have marginally lower capacities due to displacement by the coil.

Connections

Units are normally fitted with three connections up to G1 female, a G

1 /

2 boss and a G2

1 /

4 draining immersion heater boss positioned as illustrated, however these can be varied to suit user requirements. 22mm or 28mm integral compression connections are available at extra cost on most units.

These Units are not included in the catalogue because an inhibitor cannot be used.

Therefore the system would not be Part L compliant. An alternative unit would be the

F10. However, units can still be supplied on a replacement basis.

FLOWMAX MAINS PRESSURE

RANGE -

Thermal storage puts the pressure on

The Flowmax product range leads the way in thermal storage, able to supply balanced mains pressure hot water with good flow rates to all terminal outlets whilst simultaneously providing a rapid response to space heating demands is maintained at 82°C at a flowrate of approx 15 l/min.

Improving the standard

The demand for high performance mains pressure domestic hot water supply has led to the increased specification of thermal storage systems.

The W.M.A*, in consultation with leading manufacturers, has written a performance specification, the aim of which is to enable a specifier to select a thermal storage unit based on performance criteria. ie. ensuring there is sufficient domestic hot water in extreme conditions.

**The W.M.A* “Performance Specification for Integrated Thermal Stores for Heating and Hot Water” is met by all the new improved Flowmax models.**

Nothing could be simpler or safer

The Range Flowmax combines the advantage of mains pressure with the safety of traditional open vent storage in one versatile system.

Flowmax units are supplied as a complete thermal storage system, they are simple and quick to install by any qualified plumber and fully guaranteed by Range.

Flowmax now available with internal and external heat exchangers.

If higher flow rates are required or the unit is to operate in hard water conditions a high performance plate type should be used.

Product Options

Cylinder Units

For use with a separate feed and expansion tank above the

Flowmax. A common choice for refurb’ projects.

Combination Units

Commonly chosen as a combination unit because it takes tanks out of the roof space.

Central Boiler Models

Flowmax is the ideal partner for a central boiler plant. Installed in each property it allows for single metering of hot water usage and is an extremely economical system in terms of installation and running costs.

FLOWMAX

Thermal Storage Systems

How Flowmax works

Hot Water

Flowmax differs from conventional cylinders in that the water stored in the Flowmax is not the same water that is delivered to the taps. It should be thought of as a store of heat. This Primary heat store is typically maintained at 75°C.

A 50mm thick layer of CFC free foam insulation keeps heat loss to a minimum.

The heart of the Flowmax is the plate heat exchanger. Mains pressure cold water is heated instantaneously as it passes through this heat exchanger.

A flow switch detects hot water demand and switches on the store pump to assist heat exchange. Hot water can leave the plate heat exchanger at over 60°C. A thermostatic mixing valve ensures water is delivered at a safe temperature.

The store is vented via a feed and expansion tank. Only the inside of the plate heat exchanger is at mains pressure.

Flowmax electric units are heated by two immersion heaters and provide hot water only. Boiler models are heated by gas or oil and in addition to hot water can also provide heat directly to space heating

(typically radiators).

Space Heating

Previously, in a combined space heating and hot water system, operational control has focused on the boiler. Flowmax changes this and allows the thermal store to be the heart of the central heating system.

Space heating is supplied directly from the store. The store thermostat maintains the store temperature at 75°C and with this ready store of hot water the space heating demands are met far quicker than in conventional systems. As the temperature of the water in the thermal store is reduced the thermostat activates the boiler. The store is heated until it reaches it's set temperature and the thermostat shuts the boiler off.

If a timed pump overrun is fitted then the pump will continue to run, for a short while, to extract heat from the boiler circuit and maximise system efficiency.

With the thermostat ON and the thermal store controlling the system, inefficient boiler cycling is eliminated, lowering fuel consumption and maintenance bills.

Double Pump System

The typical installation uses a combination unit sited in the airing cupboard. System design is simple and incorporates 2 pumps, a cylinder stat, programmer and room stat, along with pump overrun.

The full output of the boiler is transferred into the hot store and directly controlled by the cylinder stat, it reduces boiler cycling.

The heating pump, controlled by the programmer and room stat provides instant response to the demand from the radiators.

There is no warming up period.

Cold feed to the unit is 22mm from the stop tap. In common with any other hot water cylinder, a device to prevent the build up of scale should be fitted in areas where the hardness exceeds

200mg/litre.

Hot water draw off pipe is 22mm to the bath branching off in

15mm to other terminal fittings. Overflow/warning pipe should be

” diameter and discharges in the same way as a warning pipe in a traditional system.

FLOWMAX MAINS PRESSURE

A complete package

• Ready assembled components

• Thermostatic blender

• Flow restrictor and strainer

• Expansion vessel

• Ball valve (combination unit)

• 22mm cold feed

• Timed pump overrun

• Standard overflow

• Immersion probe type thermostat or immersion heaters with integral thermostat and high limit cut - outs

Standard boiler models

The perfect partner for a gas or oil boiler, Flowmax boiler models provide balanced mains pressure hot water and fast response radiators all from the store. Provision for an immersion heater gives a back up heat source.

When installed in the double pump format the system can be considered as being split into two circuits. In the boiler circuit the store thermostat (typically set at 75°C) controls the boiler to maintain the store at the correct temperature. When the room thermostat calls for heat, the space heating pump circulates heat to the radiators.

FLOWMAX

Seven + electric model

The Flowmax 7+ Electric model is designed to make the best use of cheap rate electricity from the wide variety of tariffs available such as Economy 7 or 10.

The lower of the two immersion heaters is usually connected to the cheap rate supply and the upper one provides a boost facility for times when there is a need to reheat the unit but cheap rate electricity is not available.

The immersion heaters Range supply are manufactured to the

Maxistore specification. They are a low noise type so as not to cause disturbance when the unit is heating during the night.

Electric units provide hot water only, space heating is not fed from the store.

Sealed System

Primary (SSP) models

As the name suggests these models allow the primary system to be sealed (3.5 bar max on the standard units). This allows the radiators to be positioned above the Flowmax unit. SSP models are plumbed in like conventional indirect cylinders.

The top tank of combination type

SSP Flowmax models keeps the unit topped up as water is lost by natural evaporation.

Manufacture

Cylinders and combination units are manufactured from copper sheet to BS 2870; joints either are autogenously welded or brazed with zinc free alloy and screwed connections are of copper to provide total immunity to dezincification.

Cylinder tops and bottoms are produced to very close tolerances, guaranteeing metal thickness, both before and after forming, in accordance with the requirements of the vessel standards.

Every cylinder is pressure tested to 1.5 times its working head.

Finally each product is coated with urethane foam insulation or alternatively sprayed with a ‘permanised’ copper finish to retain its appearance and resist tarnish.

All cylinders are Part L compliant.

Thermostatic Control of Hot Water

It is essential that cylinders are fitted with a thermostat in order to conserve energy when design water temperature is reached. Generally 60°C is accepted as being an adequate temperature for most domestic purposes. 65°C should not normally be exceeded as a storage temperature.

Direct Cylinders

A thermostat is usually incorporated in electric immersion heaters and gas circulators.

Indirect cylinders

The thermostat should be fitted approximately one third the way up the hot section of the unit and, ideally, should control the operation of the boiler and pump.

Insulation

Building Regulations require all hot water storage vessels to be insulated. BS 1566 and BS 3198 allow maximum heat loss for factory applied insulation of 1 watt/per litre of hot water storage capacity under test conditions. Range cylinders comply with, or improve on this minimum performance requirement.

Physical Properties

Range blue urethane foam meets the insulation material requirements of British Standards and is covered by the ‘Kitemark’ certification of the cylinder.

A mixture of components in liquid state are sprayed onto the surface of the copper and reacts within seconds to form a low density foam coating firmly attached to the copper to ensure a perfect permanent fit.

Range blue foam lagging retains its original thickness and insulation properties throughout its life. In addition to its thermal qualities, it protects the cylinder against dents and more serious damage during transit, storage and installation.

Installation Notes

The rate of flow from a hot tap is influenced by pipe sizing and layout but is principally dependant upon the height of the feed tank above the tap, in a normal installation the water level in the cold cistern should be a minimum of one metre above the highest hot tap with sufficient space between the top of the unit and the ceiling to service the float operated valve

(ball valve). It is important to adjust the float operated valve to correct the water level at the marked water line on the side of the cold feed cistern.

Ozone Depletion

Range blue lagging is CFC-Free, HCFC-Free and has an ozone depletion potential of zero.

HOT WATER STORAGE - A BASIC GUIDE

WHAT IS A CYLINDER?

A cylinder is a vessel that stores water which can then be heated and used to supply hot taps. They are used in all types of properties - houses, shops, offices and industrial buildings. They are made from copper which is recognised as having a long service life and are manufactured in a wide range of sizes to suit all applications. Cylinders are most commonly seen in domestic properties in an airing cupboard usually in the bathroom.

HOW A CYLINDER WORKS

The cylinder is filled by cold water being fed into it from a cold feed cistern. This cistern is fed from mains supply and regulated by means of a ball valve. It is mounted above the cylinder and the cold water is fed into the bottom of the cylinder by the ‘cold feed’ pipe. The cold feed connection is usually made in the side of the cistern to avoid any debris that has settled in the bottom being drawn into the cylinder. The cistern also includes an overflow.

As the contents of the cylinder are heated the hot water rises to the top and when a hot tap is opened the hot water is drawn off from the top connection.

As the cold water is heated it expands. When the taps are closed this extra amount of expanded water must be accommodated in the system.

A vent pipe fitted to the hot water draw off accepts this expansion.

It acts as an air break and in the event of a fault condition, should boiling occur, the expanded hot water is dumped into the cold cistern and flows safely away to waste via the cistern overflow.

The cylinder is filled up by cold water entering at the bottom, at the same speed as it is being drawn off from the top by the taps. The drop that the cold water makes into the cylinder from the cold cistern is the pressure at which hot water is delivered to the taps. This drop (the height of the cold feed cistern above the cylinder) is called the HEAD.

Cylinders are manufactured from different thicknesses of copper called Grades. The more HEAD a system has, the more pressure is exerted within the cylinder and the thicker the walls need to be. The most common Grade of cylinder is

Grade 3 for domestic use where the height of the cold cistern above the cylinder is at any height up to 10 metres.

Cylinder Grades

Grade 1 to suit 25m working head, Grade 2 to suit 15m working head, Grade 3 to suit 10m working head.

KEEPING THE HOT WATER HOT

Once the water is heated in the cylinder it is important to be able to maintain its temperature until it is needed. This saves the water being constantly re - heated until it is drawn - off for use. How this is done can dramatically effect how much electricity or gas is being used to heat the water. This reflects directly on the quarterly fuel bills the user receives. Range offer their cylinders complete with insulation which keeps the water hot. This is in the form of a foam which is sprayed onto the cylinder at the factory. It ensures a high level of insulation for the cylinder and ensures performance.

CYLINDER QUALITY

There are many manufacturers of copper cylinders and quality can vary. In order for buyers to know what they are buying there is a British Standard which sets out minimum requirements for:

• the quality of workmanship when the cylinders are made.

• the amount of copper that must be used for each Grade of cylinder.

• the performance of the cylinder and its insulation.

In most instances these products have a B.S. kitemark on the label AND on the product although this may not always be visible because of the insulation.

• Direct Cylinders BS 1566 • Indirect Cylinders BS 1566

CUSTOM MADE SPECIALS

Cylinders are available in many standard patterns but can also be tailor made to suit site conditions.

i.e. the number and position of connections can be specified.

CYLINDER TYPES

The water contained in the cylinder can be heated in two different ways.

By an electric immersion heater inserted directly into the water through a fitting on the cylinder.

This is called a DIRECT TYPE cylinder.

By hot water from a central heating boiler passing through a heat exchanger mounted within the cylinder.

This heat exchanger is usually in the form of a coil. The walls of the heat exchanger become hot due to the hot water from the boiler passing through it.

The heat exchanger then transfers its heat to the surrounding cold water in the cylinder thus heating it up for use at the hot taps.

This is called an INDIRECT TYPE cylinder because the store of water is heated indirectly.

DIRECT CYLINDERS

Direct and Super Seven Direct

Direct cylinders utilise immersion heaters to heat the water.

These may be inserted from either the side or top of the cylinder.

Immersion heaters are electrical devices which have their own

ON/OFF switch usually sited conveniently for use by the householder. This may be adjacent to the cylinder or in the kitchen for example.

A neon shows when they are in operation. A popular method of switching immersion heaters is by means of a time clock.

INDIRECT CYLINDERS

There are two common patterns of indirect cylinders - DOUBLE FEED and SINGLE FEED.

SINGLE FEED INDIRECT

Range Primatic

A cylinder that has a heat exchanger which will top up the system from within automatically. This heat exchanger uses an air trap, which is created during the filling cycle, to replace the water loss automatically should water escape from the system.

There is only one cold cistern used to feed the system and therefore the cylinder is called a SINGLE FEED INDIRECT.

Direct cylinders can also be heated by a traditional coal fired back boiler.

HOT WATER STORAGE - A BASIC GUIDE

DOUBLE FEED INDIRECT

Range - Hercal, Supercal and Ultracal

Cylinders with a coil heat exchanger.

This type of cylinder is fitted to the flow and return connections of a central heating boiler. The hot water that circulates through the coil is known as

‘primary’ water. The water stored in the cylinder which is heated by the coil is called the ‘secondary’ water.

The cylinder is fed from its own cold feed cistern. Likewise a central heating system needs to be fed (topped up to take account of evaporation or water loss due to slight leaks) from a separate cold cistern. ie. a separate cold water cistern is installed to prime the system.

The separate cold feed cistern is supplied from the cold mains via a ball valve.

The ‘primary water’ is vented to this cistern by means of a vent pipe. This cistern is called a ‘primary feed and vent’ tank.

There are therefore two cold feeds to the installation and the cylinder is called a double feed indirect.

Indirect cylinders can be used with gravity or pumped circulation from the heating boiler.

Gravity circulation allows hot water to flow through the coil as the hot water rises naturally through the primary system pipework.

This means that the pipework must have a continuous gradient up to the coil from the central heating boiler.

Pumped circulation is an installation where a pump has been fitted to assist the movement of the hot water through the coil.

HIGH PERFORMANCE CYLINDERS

All Range high performance cylinders carry additional insulation to offer the best heat retention to maximise the additional performance.

DIRECT TYPES

Range - Super Seven Direct

Using the Direct type principles, high performance cylinders are manufactured to make the most of the electricity off - peak tariffs. These direct cylinders are fitted with two immersion heaters. One at the bottom of the cylinder and one higher up. The bottom immersion heater heats the whole of the cylinder contents on the overnight economy tariff.

The top immersion heater is used to boost the heat in the water at the top of the cylinder during the day should it be required.

INDIRECT TYPES

Range - Supercal and Ultracal

Using the indirect principles, high performance cylinders extract the most heating potential from a central heating boiler.

Based on the principle and design of the double feed indirect type these cylinders include a bigger, longer heating coil so that the whole of the boiler performance can be translated into water heating potential.

(Range high performance heating coils transfer heat faster and reduce the firing times and number of firing cycles of the central heating boiler).

Range high performance double feed indirect cylinders can save as much as 30% of fuel bills when compared to normal kitemarked cylinders. Can not be used on gravity systems.

COMBINATION UNITS

What is a combination unit?

Range Fortic Combination units are so called because they combine the cold feed cistern and the hot water store (the cylinder) together in one unit. The plumbing connections between cold and hot sections are factory fitted as is the vent/expansion pipe. They are designed to offer a complete compact hot water service. Combination units save installers time on site and are connected via their cold feed cistern directly to the incoming cold water in the property. They offer the option of removing all plumbing from the roof space avoiding the possibility of freezing during the winter. They are made from copper and supplied complete with ball valves and lids for the cold cisterns.

Range Combination Units are covered by BS3198. Combination units are manufactured with the hot and cold sections insulated from one another. They are available as British

Standard Direct and Indirect types, also as High Performance Direct and Indirect types in the same way as cylinders.

High performance types

Range Fortic

Direct types include two immersion heater positions. The bottom to heat the whole of the contents overnight on the off - peak tariff and the top for day - time boost operation as needed.

Indirect high performance types incorporate the bigger, longer heating coil as fitted to Supercal and Ultracal cylinders.

COMBINATION UNIT PATTERNS

Circular direct types

All direct electrical types are known as pattern 1.

Circular indirect types

All indirect types are heated by a coil heat exchanger.

Pattern 3 requires the fitting of a separate cold feed and expansion cistern to top up the primary system.

Pattern 4 incorporates a primary feed and expansion cistern with an integral feed arrangement which fills and replenishes the primary system and prevents the inter mixing of secondary and primary water.

Pattern 10 comprises two separate feed and expansion cisterns on top of the unit.

PLUMBING UNITS

Range Kernal

Designed as a complete hot and cold water service ready for connection to cold water mains.

Kernel plumbing units are factory plumbed and tested and save time on site.

Installers simply select a direct or indirect type, as standard or high performance in the same way as a cylinder. It is supplied on a steel frame with the cylinder on the base and the cold water cistern on the top ready as a complete airing cupboard.
