UK Manufactured Unvented Hot Water Cylinder Installation Guide 7
Introduction
The instructions are an integral part of the appliance and must be given to the end user on completion of the
installation in order to comply with the current regulation.
It is important to carefully read the manual to understand all the information to enable safe installation, use
and servicing. These instructions consist of details for installation, servicing, fault finding and replacement
of parts for the cylinder purchased.
JOULE will not accept any liability in the event of damage for not complying with the guidance in this
instruction manual.
The instructions for this installation manual apply to the range of JOULE Unvented Cylinders.
Safety is paramount when installing unvented hot water systems and the following instructions must be
adhered to:
• Only certified competant installers can install, commission and service the equipment supplied.
• The cylinder must be used for potable hot water only. Any other applications will be considered
incorrect use and JOULE will not be held liable for any losses resulting from such use.
• All installation and maintenance instructions must be observed to ensure the correct operation of the
equipment.
• The electric immersion must not be switched on unless the cylinder is completely full of water.
• Domestic hot water may be stored at temperatures exceeding 60°C. Preventative measures should be
put in place to negate the possibility of scalding.
• A maintenance schedule should be put in place with a competent person to service the equipment
annually to comply with the warranty conditions.
• When servicing the system the mains supply to the cylinder should be isolated.
• Only genuine spare parts should be used. A full list of items with relevant codes can be found on
page 15.
The installation must be carried out by a person competent to install unvented hot water systems.The
installation must be carried out in accordance with the following recommendations:

www.jouleuk.co.uk | www.joule.ie8
All current Building Regulations issued by the Department of the Environment, i.e. Building Regulation G3
(England and Wales), Technical Standard P3 (Scotland) or Building Regulation P5 (Northern Ireland) and the
Water Fitting Regulations (England and Wales) or Water Byelaws (Scotland). The installation should also be
in accordance with the following British Standard Codes of Practice:
BS 5449:1990 Forced circulation hot water systems
BS 5546:2000 Installation of hot water supplies for domestic purposes
BS 5918:1989 Solar heating systems for domestic hot water
BS 6700:2006 Design, installation, testing and maintenance of services supplying water.
Failure to install this appliance correctly could lead to prosecution and will invalidate the guarantee. It is in
your own interest and that of safety to ensure that the law is complied with.
Handling
Care must be taken when transporting, storing and installing the equipment:
• At least two people should li the cylinder to prevent injuries.
• The cylinder must be stored in a dry area and must never be dropped during handling.
• Packaging should only be removed at the installation location.
• The cylinder must be installed on a level floor with the required load bearing capability. Installation,
servicing, maintenance and repair must be carried out by a competent person.
• All electrical wiring must be carried out by a qualified electrician and be installed in accordance with
current I.E.E Wiring Regulations.
• A lack of safety devices can lead to potentially fatal injuries, all necessary safety devices must be in-
stalled correctly in the system. The use of an electric immersion may lead to the build up of electrical
potential in the water. This can in turn cause corrosion of the immersion. To prevent this, ensure the
immersion heater, and the hot and cold pipework are correctly bonded and connected to the earth
line.
• If plastic pipes are used they must be approved temperature resistant to 95°C at a pressure of 10bar.
A thermostatic mixer should be installed in the system to prevent the risk of scalding. If there are leaks found
in the system, shut off the cold water stop valve from the main supply and contact a competent person
immediately.
What Is Benchmark?
Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that
customers are provided with the correct equipment for their needs, that it is installed, commissioned and
serviced in accordance with the manufacturer’s instructions by competent persons and that it meets the
requirements of the appropriate Building Regulations.
The Benchmark Checklist can be used to demonstrate compliance with Building Regulations and should be
provided to the customer for future reference. Installers are required to carry out installation, commissioning
and servicing work in accordance with the Benchmark Code of Practice which is available from the Heating
and Hot Water Industry Council who manage and promote the scheme. Visit www.centralheating.co.uk

HWA Charter Member
Joule are proud to be a charter member of the the Hot Water Association (HWA), that has been formed
through the union of the two UK industry trade bodies, WMA (Water Heater Manufacturers Association) and
MODUS (Manufacturers Of Domestic Unvented Systems).
The objectives of the HWA are “To be recognised as the leading body in domestic hot water storage and,
through cooperation and partnerships, to support, drive and promote the sustained growth and improve-
ment of standards within the entire domestic hot water industry”.
The HWA operate a Charter that all members of the association observe.
The HWA Charter Statement requires that all members adhere to the following:
• To supply fit for purpose products clearly and honestly described
• To supply products that meet or exceed appropriate standards and Building And Water Regulations
• To provide pre and post technical support
• To provide clear and concise warranty details to customers
Water Supply
The performance of any unvented system is only as good as the mains water supply available. To this effect
the maximum possible water demand should be assessed, with the knowledge that the mains supplies both
hot and cold services simultaneously. The water heater itself operates at a pressure of 3bar, controlled bythe
inlet control set, and is capable of delivering over 50 litres per minute. The high quality inlet control set has been
designed to make the most of the low rates available.
The water supply should be checked to ensure it can meet these requirements. If necessary, consult the local
water authority regarding the likely pressure and flow rate availability.
Consideration should be given to upgrading existing 1⁄2” (15mm) cold mains pipework to a larger size if
the recommended minimum pressure / flow rate is not being achieved. JOULE recommend that primary
pipework used has a minimum diameter of 22mm to ensure low pressure loss.
A high static (no flow) mains pressure is no guarantee of good flow
availability. In a domestic installation 1.5bar and 25ltr/min should be
regarded as the minimum. The maximum mains pressure that the inlet
control set can cope with is 10bar.

www.jouleuk.co.uk | www.joule.ie10
Change Of Water Supply
The changing or alternating from one water supply to another can have a detrimental effect on the operation
and/or life expectation of the water heater storage cylinder, pressure temperature relief valve and heating
unit.
Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water
supply, desalinated water supply, public reticulated water supply or water brought in from another supply,
then water chemistry information should be sought from the supplier or it should be tested to ensure the
water supply meets the requirements given in these guidelines for the Joule warranty to apply.
Water Chemistry
This water heater must be installed in accordance with this advice to be covered by the Joule warranty. This
water heater is manufactured to suit the water conditions of most public reticulated water supplies. How-
ever, there are some known water chemistries which can have detrimental effects on the water heater and
its operation and/or life expectancy. If you are unsure of your water chemistry, you may be able to obtain
information from your local water supply authority. We recommend not to use water soener, however if it is
used the water is required to be kept at potable standards. This water heater should only be connected to a
water supply which complies with these guidelines for the JOULE warranty to apply.
Water Chemistry Levels Affecting Warranty
The JOULE warranty of this water heater will not cover resultant faults on components including the storage
cylinder where water stored in the storage cylinder exceeds at any time any of the following levels:
Components Maximum Permitted Levels
Total Dissolved Solids 600 mg/litre
Total Hardness 200 mg/litre
Chloride 300 mg/litre
Magnesium 10 mg/litre
Calcium 20 mg/litre
Sodium 150 mg/litre
Iron 1 mg/litre
Maximum pH 9.5
Minimum pH 6.5
Introduction

UK Manufactured Unvented Hot Water Cylinder Installation Guide 11
Total Dissolved Solids (TDS)
Some water analysis reports may state the conductivity of the water rather than the level of total dissolved
solids. Conductivity, measured in microsiemens per centimetre (μS/cm), is directly proportional to the TDS con-
tent of the water. TDS, in mg/L, is approximately 70% of the conductivity in μS/cm.
The JOULE warranty will not cover resultant faults to the storage cylinder if this water heater is connected at
anytime to a water supply where the TDS content of the water exceeds 600 mg/L. 16 In locations where TDS
approaches 600 mg/L, e.g. due to sediment, we strongly recommend fitting an appropriate filter to ensure
water entering or in the water heater does not exceed this level at any time i.e. due to sediment build up.
Features Of The Unvented Cylinder
• Made from Duplex Stainless Steel for excellent corrosion resistance.
• Strong rust-proofed steel case.
• Insulation is by means of an approved CFC/HCFC free polyurethane foam with an ozone depletion
factor of zero.

General Requirements
Wellmaster Cylinders
Only JOULE Wellmaster cylinders may be installed on a well, private water scheme or any water source that
does not come from the public mains.
Water supplied to the cylinder must conform to the water chemistry table on the previous page. A descaler
on the cold water feed may be used if required.
If any of the water parameters are higher than set out in the table
including total hardness regardless of whether or not it is fed from a
main water connection a Joule Wellmaster cylinder must be used.
If any of the water parameters are higher than set out in the table including Total Hardness regardless of whether
or not it is fed from a main water connection a JOULE Wellmaster cylinder must be used.
Siting The Unit
This unit can supply outlets above it or at some distance from it but any outlets above the unit will reduce the
available outlet pressure by 0.1 bar for every 1m of height dfference. The maximum length of the “dead leg”
should be as stated in the Water Supply (Water Fittings) Regulations 1999 G18.7, in particular to the area of
most frequent use.
Particular attention is needed if siting in a garage or outbuilding as the unit should be protected from frost.
All exposed pipework must be insulated. The unit must be installed upright on a base capable ofsupporting
its weight when full.
Sufficient access to allow maintenance of the valves should be considered. In addition the immersion heat-
ers are 400mm in length and this distance should be considered to allow withdrawal for servicing if re-
quired. The discharge pipework from the safety valves should fall continuously and terminate safely.
Negative pressure may form in cylinders installed very high in a building. To counteract this, an anti-vacuum
valve can be installed to prevent damage to the cylinder. The anti-vacuum valve ensures pressure compen-
sation as a result of air flowing into the cylinder.
Connecting To The Cylinder
All of the pipework connections on the cylinder are female threaded. Upon filling / commissioning, ensure
all connections are completely watertight.
No control or isolation valve should be fitted between the expansion
relief valve and the storage cylinder. The relief valve connections should
not be used for any other purpose.

UK Manufactured Unvented Hot Water Cylinder Installation Guide 13
Cold Mains Pipework
Run the cold main through the building to the place where is to be installed. Take care not to run the cold
pipe near hot water or heating pipe work so that the heat pick-up is minimized. Identify the cold water
supply pipe and fit an isolating valve (not supplied). A 22mm BS1010 stopcock can typically be used but
a 22mm quarter turn full bore valve would be better as it does not restrict the flow as much. Do not use
“screwdriver slot” or similar valves.
Make the connection to the cold feed of the cylinder and incorporate a drain valve. Position the inlet control
just above the Temperature & Pressure Relief Valve (TPRV) mounted on the side of the cylinder. This ensures
that the cylinder does not have to be drained down in order to service the inlet control set. Ensure that the
arrow points in the direction of the water flow. Select a suitable position for the expansion vessel. Mount it to
the wall using the bracket provided.
Balanced Cold Connection
If there are to be showers, bidets or monobloc taps in the installation then a balanced cold supply is neces-
sary. There is a 22mm balanced connection on the inlet control set.
Fitting The Inlet Control Group
Excess pressure can lead to the cylinder bursting. The inlet control set supplied has an expansion relief valve
with a 15mm connection to allow it to be connected to the tundish. Make sure that there is sufficient space
for future maintenance and also for connection of the discharge pipe for the expansion relief valve.
It is essential that this connection is not covered or closed. The hot water expansion vessel should be hard
fixed into pipework and insulated.
Hot Water Pipework
Run the first part of the hot water distribution pipework in 22mm. This can be reduced to 15mm and 10mm
as appropriate for the type of tap etc. Your aim should be to reduce the volume of the hot draw-off pipework
to a practical minimum so that the time taken for the hot water is as quick as possible.
Do not use monobloc mixer tap or showers if the balanced cold connection is not provided. Outlets of this
type can back pressurise the unit and result in discharge.
Expansion Vessel
The expansion vessel receives the increased water volume when expansion takes place as the system heats
up and it maintains a positive pressure in the system. The expansion vessel contains a flexible diaphragm,
which is initially charged on one side with nitrogen, but can be topped up with air when required.
Select a suitable position for the expansion vessel. Mount it to the wall using the bracket provided and hard
fix into pipework and insulate. Ensure that the top of the vessel is accessible for servicing. The pipe connect-
ing the expansion vessel to the system should have a diameter of not less than 15mm and must not contain
any restrictions.

www.jouleuk.co.uk | www.joule.ie14
General Requirements
Prior to connecting the expansion vessel to the system the pipework should be flushed and tested. When
the vessel is connected the system should be pressurised when cold. If the initial system water pressure is
too high, the diaphragm will be displaced too far into the vessel. This will leave the vessel unable to accom-
modate the volume of expansion water. The result of this is an increase in system pressure and the safety
valve will li.
Primary Coil Connections
Connect the primary connections (Indirect only). The primary circuit must be positively pumped. Either pri-
mary connection may be used as the primary flow. Reheat times are identical either way. The primary circuit
can be open vented or sealed, with up to a maximum pressure of 3.5 bar. If you seal the primary circuit an
additional expansion vessel and safety valve is required.
The boiler may be Gas, Electric or Oil but must be under effective thermostatic control. Uncontrolled heat
sources such as some AGA’s, back boilers, solid fuel stoves, etc. are not suitable. Please contact our Tech-
nical department for guidance. Connect the two port zone valve (indirect only) into the primary flow pipe-
work. The direction of flow arrow should be towards the primary flow connection.
Installing The Two Port Motorised Valve
The function of the Two Port Motorised Valve prevents the cylinder from overheating. It can be installed on
either horizontal or vertical pipework.
If it is mounted onto horizontal pipework the valve head must face upwards. The direction of flow is marked
on the body of the valve with arrows.
Thermostatic Mixer
When installing a solar system with an unvented JOULE twin coil cylinder, a thermostatic mixing valve should
be installed. Its function is to act as an anti scald protection. The thermostatic mixer is to be set to a temper-
ature of between 30°C and 60°C and is supplied by the installer.
Secondary Circulation
On larger installations long pipe runs to draw-off points can cause significant volumes of water to be drawn
off before an acceptable temperature can be reached. Secondary pumped circulation using a stainless steel
or a bronze pump, and combined with effective time and temperature controls can overcome this problem.
Where secondary return circulation is required the pipework should be run in 15mm pipe. A suitable WRAS
approved stainless steel or bronze circulation pump must be used. A check valve must also be installed to
prevent back flow.
On large secondary circulation systems it may be necessary to incorporate an extra expansion vessel into the
circuit to accommodate the increased system water volume. Secondary circulation should be avoided on
Direct electrically heated units being used on off-peak electricity tariffs. It should be noted that the use of a
secondary circulation circuit can increase running costs as there will be circulation pipe losses. High levels
of insulation on secondary pipework are required to keep energy losses to a minimum.

UK Manufactured Unvented Hot Water Cylinder Installation Guide 15
Dead Legs
The length of hot water draw off to taps and other outlets should be kept to a minimum to reduce the amount
of cold water drawn off before the hot water arrives. The maximum recommended dead leg lengths are
shown in the table below. Where there is more than one size of pipe on a dead leg, the equivalent length
and size should be estimated. Where the dead leg length exceeds the
recommended maximum, secondary circulation should be installed. It should be controlled by a time switch
and incorporate a motorized valve that can prevent gravity circulation in the circuit.
Pipe Size (mm) Maximum Length (m)
10, 12 20
15, 22 12
28 8
35 and above 3
System Noise
Noise in pipework may occur as a result of expansion of pipework over joists or where the pipe has been
le touching other pipes or a part of the building structure. Care must be taken to ensure that the pipework
is correctly bracketed, is not in tension or compression, and does not carry the weight of components such
as a circulation pump.
Setting The Hot Water Temperature
The hot water temperature is set on the dual thermostat by the competent person during the
installation. The dual thermostat should be set to 60°C. If you are heating water in the cylinder for the first
time, or the time controls for the DHW zone have been off for a prolonged period of time, the cylinder may
take additional time to heat up.
Inappropriate adjustments can lead to the damages in the system.
If any changes are made to the cylinder, the controls, the water and
power supply lines or the expansion relief components there is a
risk of steam escaping or rupture to the system.
