Product Information

The Adveco Stainless Steel Range (SSB, SSI, and SST) is a versatile and modular range of domestic hot water vessels. These stainless steel cylinders can be fitted with up to two high-capacity stainless steel indirect heating coils or specialized flanges and immersion heaters as required by the application. The range is divided into three types of vessels:

1. Stainless Steel Buffer (SSB) vessels: These vessels are supplied with two blank flanges and zero heat exchange coils, serving primarily as buffer vessels.
2. Stainless Steel Indirect (SSI) vessels: These vessels are supplied with one heat exchange coil fitted into the lower flange of the tank, with a blank flange fitted into the top.
3. Stainless Steel Twin-Coil (SST) vessels: These vessels are supplied with two heat exchange coils that can either operate independently or be connected together to serve a single high-capacity heat source.

The full range of stainless steel vessels is compatible with direct heating options by including the Adveco range of electric immersion heaters. Additionally, the SSB range offers two subtypes by substituting one or both standard blank flanges for alternative specialized flanges:

• Stainless Steel Buffer Electric (SSB-E or SSB-E2): These vessels feature one to two electric element mounting flanges, each capable of housing one or two Adveco electric immersion elements. This allows for multiple immersion heaters to be combined with a single tank, providing a highly adaptable electric water heater for domestic hot water systems.

Product Description

Adveco Stainless Steel Cylinders: SSB, SSI, SST

• Adveco Stainless Steel Cylinders are a versatile, modular range of domestic hot water vessels that can be fitted with up to two high-capacity stainless steel indirect heating coils or specialised flanges and immersion heaters as required by the application. The range is divided into three types of vessel depending on the number of heat exchange coils included:
• Stainless Steel Buffer (hereafter “SSB”) vessels are supplied with two blank flanges and zero heat exchange coils, and primarily serve as buffer vessels only.
• Stainless Steel Indirect (hereafter “SSI”) vessels are supplied with one heat exchange coil fitted into the lower flange of the tank, with a blank flange fitted into the top.
• Stainless Steel Twin-Coil (hereafter “SST”) vessels are supplied with two heat exchange coils that can either operate independently or be connected together to serve a single high-capacity heat source.
• The full range of stainless steel vessels are compatible with direct heating options by the inclusion of the Adveco range of electric immersion heaters.
• Two subtypes of the SSB range are also available by substiting one or both standard blank flanges for alternative specialised flanges:
• The Stainless Steel Buffer Electric (hereafter “SSB-E” or “SSB-E2” depending on the number of electric flanges included) feature one to two electric element mounting flanges, each capable of housing one or two
• Adveco electric immersion elements. This makes it possible for multiple immersion heaters to be combined with a single tank, resulting in a highly adaptable electric water heater to serve domestic hot water systems.
• The Stainless Steel Buffer Direct (hereafter “SSB-D”) range features a direct vessel connection flange in place of the lowest blank flange, allowing the stainless steel vessel to be used as a buffer with a direct connection to a water heater.
• The Technical Drawings located on pages 22-25 can be consulted for a visual reference to the various vessels within the Adveco Stainless Steel Cylinder range.
• The Adveco Stainless Steel Cylinder range is designed, manufactured, and tested in the EU to the requirements of:
• The Pressure Equipment Directive
• EN 12897:2016
• The scope of EN 12897:2016 covers indirectly heated, mains pressure storage water heaters, with or without immersion heater backup, up to 1000 litres and 10 bar. The SSB, SSI and SST range of stainless steel vessels up to 1000 litres have been produced to the requirements of this standard.
• Vessels with storage capacities of 1000 litres and greater have been designed and manufactured within the spirit of this standard, and have been type tested in accordance with section 6.2. Production units in this category are tested to section 6.3. This supports the requirement for sound engineering as prescribed by the Pressure Equipment Directive for vessels covered by Article 3, Paragraph 3.
• The full range of stainless steel vessels are WRAS approved products, with approval reference 1605319.

Responsibilities of the User

• Hot water systems pose a potential risk for building occupants regarding temperature and biological risks. It is the responsibility of the building controller to assess the risk to the occupants of scalding or Legionella and put in place suitable steps to protect the occupants.
• The risk assessment must be carried out by someone suitably qualified. The following documents offer guidance and assistance on responsibilities:
  • ACOP L8, 2014
  • HSG274 Part 2
  • Health and Safety at Work Act
  • Workplace (Health, Safety and Welfare) Regulations HTM 04 01 Part A and B
  • Building Regulations Part G
  • BS EN 806 All parts
  • CEN/TR 16355
• And any other standards, laws, guidelines, or rules in force in the location of the installation, past or future, that are current at the time of installation. This installation manual complements these rules and must not be considered to override them in any way.
• Following the commissioning of a system and in compliance with the procedures and advice contained within this manual, responsibility lies with the building controller to maintain a safe standard of operation and regular maintenance procedures as required by the risk assessment. This includes ensuring that the unit is not operated at temperatures or pressures in excess of those stated on the vessel data plate. Nor should the vessel be exposed to a full or partial vacuum, such as can be present during draw-off or drainage of the unit while the cold feed or vent are closed or obstructed.
• Failure to maintain a minimum of annual maintenance may void any and all warranties. Full maintenance procedures should only be carried out by a suitably qualified person. Basic maintenance regimes, as determined through risk assessment, should be carried out by the user as directed on page 16.
• Adveco Ltd. advise that heating systems in unoccupied premises, or that are subjected to long periods of shutdown, should be drained down according to the procedure on page 16, to remove the risk of failure and/or damage occurring while the system is not being monitored.

Responsibilities of the Installer / Designer

In compliance with the procedures and advice contained within this manual, responsibility lies with the installer to ensure that the vessels are correctly and safely installed in line with all local regulations and laws. In all cases, the relevant laws and regulations take precedence over the instructions contained within this manual.

Requirements of the Installation

• The SSB, SSI, and SST range of stainless steel vessels are suitable for use with storage or heating of potable water in installations up to a maximum pressure of 6 bar. Any unvented cylinder installation should be notified to Building Control. This is best done through a Competent Persons Scheme by installers holding a valid unvented domestic hot water ticket.
• The following documents set out the standards of installation that must be adhered to:
  • EN 806 All Parts
  • EN 8558:2015
• Note that the installation of any electric heating element requires the use of an earthed power supply.

Location & Handling

• Suitable methods of moving a vessel include the use of a forklift truck where the vessel is securely fixed to a pallet capable of supporting its weight, or by boom crane using adequate textile slings of suitable capacity to lift the weight of the tank. Vessels should not be lifted using the insulation, by chains, or by straps that may damage the insulation, connections, or walls of the tank. Care should be taken when moving or lifting to minimise the risk of damage to the vessel.
• The vessel must be located inside the building and positioned on a level base capable of supporting the unit when full. Floor loading calculations should include the total filled weight, being equivalent to the sum of the empty weight of the vessel and the weight of any installed coils or flanges, plus the water volume in litres (where 1 litre of water weighs 1 kg). For tank and coil weights, consult pages 17-20. All vessels include welded feet with fixing holes.
• The vessel should be positioned to provide suitable clearances as shown below in figure 1, and should permit access for visual inspection and maintenance of all connections and fittings. Consideration should be given to the inspection, removal and replacement of any flanges, heating coils, immersion heaters, thermostats, and safety valves present, as well as replacement of the entire vessel.
• Any water storage vessel requires some provision against damage to surrounding infrastructure, electronics, and equipment in the event of a leak, damage, or vessel failure. Acceptable methods of protection include suitable bunding, gulley, drainage, or a leak detection and warning system.
• All tanks are supplied with the insulation jacket already fitted to the vessel. The insulation jacket can be removed if necessary to move the vessel into location, but must be replaced prior to the connection of any pipework.

Tank Connections

Flanges and Primary Pipework

• The stainless steel range of indirect tanks are produced with flanges for up to two removable coils, leading to three distinct product ranges depending on the number of coils installed. The SSB Stainless Steel Buffer range is provided with blank flanges and no coils installed. The SSI Stainless Steel Indirect range is supplied with a single coil mounted in the lower flange, and the SST Stainless Steel Twin-Coil range is provided with coils fitted into both flanges. As a result, the stainless steel range can cater for most hot water applications. The coils fitted within the SST can be used individually for two different heat sources, or can be combined by external, additional pipework (not supplied) to give a larger capacity system. With these combinations the vessel can be used as a preheater, afterheater, buffer or standalone water heating system.
  Connections to the vessel should be made according to the locations and sizes denoted on pages 8 and 17. All pipework should be of an appropriate, non- corrosive material, and should be supported outside of the vessel to prevent excessive load bearing upon the tank connection points. Pipework should be arranged to facilitate suitable access to system components.

• All flanged connections to the vessel must be tightened in a diametrically opposed sequence to prevent uneven loads across the connection. All flange gaskets must be pasted using a non-toxic silicone based jointing compound suitable for use with hot and cold potable water.

• While installing pipework, consideration should be given to removal of the coils for maintenance and cleaning of the tank. Valves and union type fittings are required. A drainage connection should be included downstream of the union fittings.

SST Combined Coils
For larger capacity systems with one heat source, the two heating coils can be combined. The standard way to do this is in series so that the primary flows through the top coil and then through the bottom coil. To estimate the total kW capacity with both coils, based on an 80°C primary temperature, add the kW capacity for the top coil at 80°C to the kW capacity for the bottom coil at 70°C. For technical details on kW capacities at 70°C, on different temperatures, or if a more accurate calculation is required, please contact the Adveco Design Department.

SST Separate Coils
In the case of two heat sources, the lower grade heat or less costly energy source should go into the bottom coil to act as a preheat. The more reliable source of high grade heat (usually a boiler) should be piped into the top coil.

Air Relief
Each coil has a 3/8 inch connection for an air bleed point to commission the coils. Air relief valves are not supplied as standard.

Secondary Pipework

General

• A standard installation will include the stainless steel cylinders as part of a mains-fed system. The pipework should be correctly sized to carry the maximum simultaneous demand of hot water for the building. This may or may not be the same size as the cold feed connection.
• All installations must include an anti-vacuum valve to equalise pressure within the tank and prevent damage due to negative pressure during drain-down or draw-off.

Cold Feed

• All cold feed pipework must be fitted with safety equipment to prevent overpressure and allow for the expansion of hot water in the system. This must include a check valve and a pressure relief valve set normally to the maximum working pressure of the tank, but no more than 1.5 bar higher than the maximum working pressure in line with the regulations set out in EN 8558 section 4.3.29.1.
• All mains-fed systems should additionally include a pressure reducing valve and strainer. The standard kit supplied by Adveco has a variable pressure reducing valve with settings available between 1 bar and 5.5 bar. The domestic hot water pressure must exceed the primary system pressure at all times to protect against contamination of the DHW in the unlikely event of a leak from the coil.
• There must not be any type of isolation between the pressure relief valve and the vessel. Safety equipment should be installed at the cold inlet unless otherwise specified.
• The cold feed equipment should be supplied as part of an unvented kit by Adveco Ltd., inclusive of an expansion vessel and temperature and pressure relief valve with a pressure setting at least 0.5 bar above the pressure relief valve setting but no more than 1.5 bar higher than the maximum working pressure of the tank, in line with EN 8558 section 4.3.29.1. A 3/4’’ inch valve is suitable for use with most indirect systems.
• The expansion vessel should be calculated to be roughly 5% of the total hot water system volume for systems operating at around 3 bar. Please contact the Adveco Design Department to obtain a full calculation if required, or for high pressure applications. The expansion vessel pressure must be set equal to the cold fill pressure of the system, and must be set with no pressure on the wet side of the membrane. The expansion vessel must be situated on the cold feed pipe. For tanks arranged in series, only one expansion vessel should be used at the beginning of the system. Consideration may be given to flow-through type expansion vessels for systems identified as high risk.
• The expansion vessel branch can have a lock shield valve so long as the relief valve is not on the same branch.
• For further notes on tank and pipework arrangements, please refer to the technical drawings found on pages 22-25 of this manual.

Drain
The cold feed is located at the lowest part of the cylinder to meet anti- Legionella requirements. A drain should be installed in the cold feed at the lowest point, before the connection to the cylinder. The drain valve shall be of suitable size to allow draining of the tank in a reasonable amount of time. It is recommended that a 1/4 turn lever valve and plug or cap are used and that the valve size be one size smaller than the cold feed connection size. A suitable drain or gulley should be provided to allow draining of the tank.

Vented Installations:
In case of a vented system the unvented kit can be omitted. From the hot flow there must be an uninterrupted open vent with no valves, of at least 19mm internal diameter, reaching above the water level of the cold water tank and discharging to a safe place (not into the cold tank). It is considered good practice to fit a temperature and pressure relief valve even on a vented system.

Discharge Pipework

Discharge from relief valves

• Discharge pipework requirements for the UK are found in Building Regulation Part G. They are summarised here but it is recommended to read the regulations in full at http://www.planningportal.gov.uk/buildingregulations/approveddoc-uments/partg/approved
• D1, the pipe from the relief valve to the air break, must have the same diameter as the valve, must be metal, and must be no longer than 600mm. An airbreak, such as a tundish or a funnel, must be installed at the end of D1.
• D2, the pipe from the air break to termination, must be at least one size larger than D1, must have at least 300mm vertical drop before a bend, and must have a continuous fall. It should typically be metal, but PP is acceptable (note: PP is push-fit plastic. ABS and PVC solvent welded plastics are not suitable).
• If D2 is longer than 9m total equivalent length (based on 1.4m per bend), then its diameter must be increased. Please refer to Building Regulation G3 at http://www.planningportal.gov.uk/buildingregulations/ . If a number of D2 pipes are combined, the diameter of the common pipe should be one size larger than the biggest D2 pipe.
• D2 should be terminated in one of the following ways:
  • Into a soil stack, suitable for the temperature, with a mechanical seal, and with no sanitary appliances on it and a warning not to use the pipe for sanitary appliances.
  • Into a trapped gulley with the pipe end below the grate but above the water seal.
  •  Terminating at low level to a suitable external ground level surface with a guard around the pipe end and that end within 100mm of the ground
  • At high level into a suitable hopper or onto a roof that can withstand the temperature and does not have plastic guttering within 3m of the discharge and does not create a risk to people below.

Secondary Return Pipework

• A secondary return is the best way to ensure that there is hot water at the outlets in a short amount of time. In some cases this could be done with trace heating, but the amount of electricity necessary to do this must be considered. In some small systems it is not necessary to use either, and the hot water can flow directly to the taps. The water at the furthest outlet must be 50°C within one minute (55°C in healthcare premises), although this may not be acceptable to all users and a secondary return arrangement should be considered for waiting times of longer than 20 seconds. In all cases, site legionella protection policy takes precedence over this document.
• The secondary return pump should be sized to give a suitable flow of hot water around the system to ensure the returning temperature is at least 50°C. The pipework must be insulated. The pump must have a check valve on the positive side of the return pump to prevent cold flow to the hot outlets.
• For SSB and SSI vessel applications, the secondary should return into the cold feed of the water heater.
• For the SST Twin-Coil range, the secondary should enter the hot water system above any low grade heat sources, just before the final high grade heat source. For a standard indirect water heater installation where both coils are connected together from one heat source, the return should go into the cold feed downstream of the unvented kit / inlet combination safety group. In cases where two heat sources are used, the secondary return should be piped into the centre of the tank.

Shunt / Destratification Pump

• In installations where the secondary return is piped into the cold feed, it may be considered that all requirements for de-stratification or purging are met. This must be confirmed by site Legionella risk assessment.
• In installations without secondary returns, or when it is piped into the centre of the tank, it is advised that the tank is entirely heated to 60°C for at least one hour per day. This should be done with a destratification pump piped from the outlet to the inlet. It should be timed with a clock to run at a low demand period of the day, while the heat source is on, for long enough that the bottom of the tank will achieve 60°C for one hour. In installations with multiple heat sources, a destratification pump should not run permanently.
• For buffer vessel applications, the shunt pump between the buffer outlet and the water heater inlet should be timed to be the same as the water heater.

Multiple Tanks

In case of a multiple tank system the following must be adhered to:

Series Tanks
Series tanks are used in installations as preheaters and afterheaters. A low grade or renewable heat source is used to heat the preheat and the water is transferred to the afterheater, where the additional energy required will top up the temperature. The afterheater is designed to be able to supply the entire load if necessary, and it is always kept up to temperature while the building is occupied.

1. The unvented kit (with an expansion vessel sized for the entire system) or inlet combination group should be installed on the cold feed side of the preheat vessel.
2. The secondary return should be piped into the inlet of the afterheater.
3. A purge pump should be installed from the afterheater outlet to the preheater inlet to allow for thermal disinfection of the preheat. This can be on a timer or on a controls system to heat the preheat to 60°C as often as required by the risk assessment as referenced on page 5.
4. The afterheater must have a temperature and pressure relief valve.
   If it is desirable to be able to drain one tank without affecting the others, an isolation valve can be installed between the two tanks only if another pressure relief valve is installed on the afterheater side of the valve.
   No check valve or expansion vessel should be installed between the preheater and afterheater.

Parallel Tanks

1. All pipework including the secondary return to parallel tanks should be balanced either by pyramid or by reverse return.
2. It is best if each tank has its own unvented kit / inlet combination group to allow for easy servicing of each unit. Consideration should be given to one common pressure reducing valve to ensure equal pressure and flow through each tank.
3. The secondary return should connect into each cold feed.

SSB Buffer Tanks

1. Where a buffer vessel is present, all hot water flow into the building must come from the buffer.
2. The cold feed should connect into the water heater.
3. The output from the water heater should connect into the bottom of the buffer vessel.
4. It is advised to include a shunt pump, from the buffer outlet to the inlet of the water heater.
5. An unvented kit / inlet combination group should be installed on the water heater, with a temperature and pressure relief or inlet combination security group valve on the buffer vessel.
6. The secondary return from the building should pass into the cold feed of the water heater.

Controls

• Every hot water vessel must be fitted with a method of temperature control. This can either be a control thermostat in the tank, a sensor, or a differential control between the tank temperature and the heat source.
• This must be set to ensure a water temperature of at least 60°C throughout the vessel. The temperature control setting should be subject to a risk assessment in accordance with local building regulations. In most cases, it is recommended to fit thermostatic mixing valves on all outlets for personal use.
• The temperature control method should be set to provide a water temperature at outlets of at least 50°C (55°C in healthcare premises) within one minute, and a minimum return temperature of 50°C.
• Every vessel that contains a heat source must additionally be fitted with a non-self-resetting overheat thermostat capable of preventing heat entering the tank from all sources, by either stopping the primary flow or by turning off the heat source. Stopping the primary flow may be achieved by a spring-loaded zone valve, or by turning off the pump, providing that thermosyphoning cannot occur.

Time control

• It is acceptable to shut off the hot water system if the building is unoccupied for a short period over night or on the weekends. Following a short shutdown, the hot water system must come on long enough before occupation so that it has been up to temperature for at least one hour.
• Longer shutdowns must be risk assessed and may require flushing and disinfection before startup.

Frost protection
In normal working operation, the tank is protected against frost because it will be maintained at temperature. In situations where it will be shut down because the building is unoccupied, consideration must be given to freezing of the water within the tank and pipework. This is best dealt with by a frost thermostat (not supplied as standard) in the room to bring on the heat source and secondary pump at 5°C.

Maintenance Operations

• Hot water system maintenance should be determined by the building’s risk assessment and legionella protection policy. While full maintenance and cleaning of tanks should be carried out by a trained operative, there are regular hot water system maintenance checks that must be carried out more frequently and can be done by the building controller’s nominated person. These include monthly checks of the hot water temperature and regular flushing of low use outlets.
• The more involved maintenance regime of a tank will vary from site to site depending on water conditions and use. Maintenance must take place at least yearly, but more frequent visits may be required depending on the condition of the unit after one year. The main reason for frequent maintenance is due to scale formation in the tank. Consideration should be given to scale control in hard water areas to reduce descale frequency.
• The maintenance of a tank involves checking the system and cleaning the tank.

Checks to carry out:

• Temperature is correct and above 60°C.
• Return temperature is above 50°C and in line with relevant local regulations.
• Furthest outlet temperature is above 50°C (55°C for healthcare) in 60 seconds.
• Control stat is calibrated and correctly shuts off heat source.
• Overheat stat is functional and stops heat to the tank.
• Relief valves operate and discharge correctly.
• All valves travel free.
• The system has no leaks.
• The pressure of any expansion vessel on the cold feed pipework is equal to the cold feed pressure (checked when there is no pressure on the water side of the diaphragm).

Cleaning:

• All filters should be cleaned.
• The tank should be drained down, cleaned and descaled.
• All heater batteries should be descaled.

Drainage Procedure:

• Turn off all direct or indirect heat sources connected to the vessel.
• Turn off any system pumps and isolate all connections to and from the vessel.
• Ensure that the vessel drain connection is connected to, or positioned over, a drain or gulley. For pressurised systems, open the drain valve connection to release the pressure within the vessel.
• Open a safety valve or remove an automatic air vent connection on the tank to allow air into the unit and prevent negative pressure build-up during drainage. Alternatively, ensure there is no isolation between the DHW outlet of the tank and a draw-off point, and open the tap. Allow the water in the pipework to drain, and leave the tap open to allow ingress of air to the vessel.
  Allow the vessel to fully drain via the drain valve connection.
  Note that the air vent connections located on the flanges of SSI and SST tanks only connect to the heating coils, not the water cylinder itself.
  Note that for SSI and SST vessels, the indirect heating coils may also need to be drained. This should be done via a drainage point included on the primary pipework.
