The PulsaCoil BP shown schematically above is a very highly insulated appliance. As such, the products will allow a pass to be achieved in SAP2005 even in small apartment situations, which is to provide an improved method of supplying mains pressure hot water when using a suitable off peak electric supply/tariff .

The heat losses from thermal stores should not be directly compared with heat losses from unvented or vented cylinders because they are treated differently in SAP. The SAP calculator takes account of the type of store and various correction factors are included to reflect the different ways that the hot water and heating operates.

The main feature of the concept is that hot water can be supplied directly from the mains at conventional flow rates without the need for temperature and pressure relief safety valves or expansion vessels. This is achieved by passing the mains water through heat exchangers inside the thermal store. The outlet temperature of the domestic hot water is maintained by a thermostatic blending valve.

The Building Regulations L1A: New dwellings/L1B: Existing dwellings and the requirements set out in the Domestic Heating Compliance Guide specify that “where the mains water hardness exceeds 200ppm provision should be made to treat the feed water to water heaters and the hot water circuit of combination boilers to reduce the rate of accumulation of lime scale”.

To comply with this requirement the hardness of the mains water should be checked by the installer and if necessary the optional factory fitted in-line scale inhibitor should be specified at the time of order for hardness levels between 200 and 300 ppm (mg/l).

Where the water is very hard ie 300ppm (mg/l) and above the optional polyphosphate type, scale inhibitor should be specified at the time of order. However, this will need to be fitted by the installer at a suitable point in the cold water supply to the appliance.

Because this product does not require a safety discharge from a temperature and pressure relief valve, any installations will be easy to incorporate into the building and will not suffer from the problems associated with using PVCu soil stacks to take the discharge from unvented cylinders.

Notes:-

1. The heat losses from thermal stores should not be directly compared with heat losses from unvented or vented cylinders because they are treated differently in SAP. The SAP calculator takes account of the type of store and various correction factors are included to reflect the different ways that the hot water and heating operates.
2. The flow rates are based on a 35°C temperature rise and assume that recommended pressures and adequate flow are available at the appliance. The flow rate will be reduced if the available water pressure is below that recommended.
3. The domestic hot water outlet temperature is automatically regulated to approximately 52°C at the bath flow rate of 18 litres/min recommended by BS 6700. The temperature is user adjustable.

PLAN OF APPLIANCE CONNECTIONS

The PulsaCoil BP units are supplied on an installation base to allow the pipe runs to connect to the appliance from any direction. It is easier if all pipes protrude vertically in the cut out area shown. Compression or push fi t connections can be used. All pipe positions are approximate and subject to a tolerance of +/- 10mm in any direction. Space will also be required for a 15mm cold water supply and a 22mm warning / overflow pipe (if the optional extra ball valve and overflow connector have been specified. If a warning/overflow pipe is NOT provided the F&E Cistern should be filled from a temporary hose connection incorporating a double check valve. This can be from a temporary hose connection supplied from a cold water tap or a permanent cold branch provided adjacent to the Top up Cistern. The temporary connection must be removed once the appliance is filled.

Note: All dimensions are shown in mm and are to the centre line of pipework.

Hot and Cold Water System
General

A schematic layout of the hot and cold water services in a typical small dwelling is shown below. PulsaCoil BP will operate at mains pressures as low as 1.5 bar and as high as 5 bar although the recommended range is 2-3 bar dynamic at the appliance. It is also important to check that all other equipment and components in the hot and cold water system are capable of accepting the mains pressure available to the property. If the mains pressure can rise above 5 bar or the maximum working pressure of any item of equipment or component to be fitted in the system, a pressure limiting (reducing) valve set to 3 bar will be required.

If you encounter a situation where the water pressure is adequate but flow rates are poor please contact our technical helpline for details of an effective solution.

No check valve or similar device should be fitted on the cold water supply branch to the PulsaCoil BP.

The Building Regulations L1A: New dwellings/L1B: Existing dwellings and the requirements set out in the Domestic Heating Compliance Guide specify that “where the mains water hardness exceeds 200ppm provision should be made to treat the feed water to water heaters and the hot water circuit of combination boilers to reduce the rate of accumulation of lime scale”.

To comply with this requirement the hardness of the mains water should be checked by the installer and if necessary the optional factory fitted in-line scale inhibitor should be specified at the time of order for hardness levels between 200 and 300 ppm (mg/l).

Where the water is very hard ie 300ppm (mg/l) and above the optional polyphosphate type, inhibitor should be specified at the time of order. However, this will need to be fitted by the installer at a suitable point in the cold water supply to the appliance.

The hot water flow rate from the PulsaCoil BP is directly related to the adequacy of the cold water supply to the dwelling. This must be capable of providing for those services, which could be required to be supplied simultaneously, and this maximum demand should be calculated using procedures defined in BS 6700.

If a water meter is fitted in the service pipe, it should have a nominal rating to match the maximum hot and cold water peak demands calculated in accordance with BS 6700. This could be up to 60ltr/min in some properties.

Note: The diagram below shows the Top up cistern with ballvalve and warning/overflow pipe. The ballvalve/overflow connector can be supplied as an optional extra if required. However, the standard preferred arrangement is for the cistern to be manually filled from a temporary hose connection fitted with a double check valve.

The cistern must not be fitted more than 6 meters above the PulsaCoil BP appliance itself.

Hot and Cold water System
Pipe Sizing / Materials

To achieve even distribution of the available supply of hot and cold water, it is important in any mains pressure system, that the piping in a dwelling should be sized in accordance with BS 6700. This is particularly important in a large property with more than one bathroom.

However, the following rule of thumb guide lines should be adequate for most smaller property types as long as water pressures are within the recommended range.

1. A 15mm copper or equivalent external service may be sufficient for a small 1 bathroom dwelling (depending upon the flow rate available), but the minimum recommended size for new dwellings is 22mm (25mm MDPE).
2. The internal cold feed from the main incoming stop tap to the PulsaCoil should be run in 22mm pipe. The cold main and hot draw-off should also be run in 22mm as far as the branch to the bath tap.
3. The final branches to the hand basins and sinks should be in 10mm and to the baths and showers in 15mm. (1 metre minimum)
4. We would recommend that best results for a balanced system are achieved by fitting appropriate flow regulators to each hot and cold outlet. This is particularly relevant where the water pressures are above the recommended water pressure range. Details of suitable flow regulators are provided in Appendix.

All the recommendations with regard to pipework systems in this manual are generally based on the use of BS/EN Standard copper pipework and fittings.

However, we are happy that plastic pipework systems can be used in place of copper internally as long as the chosen system is recommended for use on domestic hot and cold water systems by the manufacturer and is installed fully in accordance with their recommendations.

It is also essential that if an alternative pipework material/system is chosen the manufacturer confirms that the design criteria of the new system is at least equivalent to the use of BS/EN Standard copper pipework and fittings.

Taps/Shower Fittings
Aerated taps are recommended to prevent splashing.

Any type of shower mixing valve can be used as long as both the hot and cold supplies are mains fed. However all mains pressure systems are subject to dynamic changes particularly when other hot and cold taps/showers are opened and closed, which will cause changes in the water temperature at mixed water outlets such as showers. For this reason and because these are now no more expensive than a manual shower we strongly recommend the use of thermostatic showers with this appliance.

The shower head provided must also be suitable for mains pressure supplies.

However, if it is proposed to use a ‘whole body’ or similar shower with a number of high flow/pressure outlets please discuss with the Gledhill technical department.

The hot water supply to a shower-mixing valve should be fed wherever practical directly from the PulsaCoil BP or be the first draw-off point on the hot circuit. The cold supply to a shower-mixing valve should wherever practical be fed directly from the rising mains via an independent branch. The shower must incorporate or be fitted with the necessary check valves to provide back-syphonage protection in accordance with the Water Regulations.

The supply of hot and cold mains water directly to a bidet is permitted provided that it is of the over-rim flushing type and that a type ‘A’ air gap is incorporated.

Hot and Cold Water System

If the length of the hot water draw off pipework is excessive and the delivery time will be more than 60 seconds before hot water is available at the tap, you may wish to consider using trace heating to the hot water pipework such as the Raychem HWAT system. Please consult Gledhill technical department for further details.

Also a conventional pumped secondary circulation system can be used with this appliance.

It is important that the cold water pipework is adequately separated/protected from any heating/hot water pipework to ensure that the water remains cold and of drinking water quality.

SYSTEM DETAILS

DESIGN

Electrical Installation

The Schematic arrangement of the wiring within the PulsaCoil BP is shown opposite.

The whole of the electrical installation shall be designed and installed by a competent person fully in accordance with the latest edition of the Requirements for Electrical installations BS 7671.

The PulsaCoil BP appliance is provided with two side entry 3kW immersion heaters and has been designed to generally operate with an off peak supply.

The lower immersion heater heats the whole of the contents and is normally connected to the off peak supply.

The upper immersion heater is positioned at a level on the PulsaCoil BP to heat the top 50 - 80 litres of the store - see Technical Data Table on page 5. This is connected to the unrestricted on peak supply and is switched manually by the householder using the off -peak controller, eg. Horstman Electronic 7 Controller.

The size of the appliance and the need to use the on peak boost facility is reduced if a better off peak tariff can be agreed with the electrical supply company - see Model Selection Guide on page 5.

The typical wiring arrangement is shown in figure 1.7. An economy 7 controller (eg Horstman Electronic 7) is used for a manual boost and automatic off -peak heating of hot water.

If a factory fitted scale inhibitor has been specified, then it should be wired to a permanent supply as shown in figure 1.8.

 INSTALLATION

For Gledhill PulsaCoil BP Parts and Spares click on the following link: Gledhill PulsaCoil BP Parts And Spares

The appliance is designed to be installed in an airing/cylinder cupboard and the relevant minimum dimensions are provided in the Technical Data section of this manual.

Because of the ease of installation we recommend that the cupboard construction is completed and painted before installation of the appliance. The cupboard door can be fitted after installation.

If the unit needs to be stored prior to installation it should be stored upright in a dry environment and on a level base/floor.

Installation and maintenance access is needed to the front of the appliance and above the top up cistern. See the Technical Data section of this manual for further details.

The minimum dimensions, contained in the Technical Data section, allow for the passage/connection of pipes to the appliance from any direction as long as the appliance is installed on the installation base provided. If the installation base is not used extra space may be needed to allow connection to the pipework and the whole of the base area should be continuously supported on a material which will not easily deteriorate if exposed to moisture.

The floor of the cupboard needs to be level and even and capable of supporting the weight of the appliance when full. Details of the weight when full is provided in the Technical Data section of this manual.

The appliance is designed to operate as quietly as practicable. This will be most noticeable if the cupboards are located adjacent to bedrooms, on bulkheads, or at the mid span of a suspended floor. Some noise may also be experienced from the immersion heaters as the store approaches its design temperature.

Cupboard temperatures will normally be slightly higher than in a conventional system and the design of the cupboard and door will need to take this into account. No ventilation is normally required to the cupboard.

The separate Top up cistern will need to be located on top of the appliance or at high level in the cupboard housing the PulsaCoil BP. The dimensions and clearances are provided in the Technical Data section of this manual. If the top up cistern is sited remotely, the location will need to provide a suitable route for the cold feed expansion pipe as well as the open safety vent pipe. If the ballvalve/overfl ow connector have been ordered (available as optional extras), the location will also need to provide a suitable route and discharge position for the warning/overflow pipe and the ballvalve supply from the mains cold water system.

Note: The standard appliance is supplied with a cistern without a ballvalve/overflow for filling manually.

An electrical supply must be available which is correctly earthed, polarized and in accordance with the latest edition of the IEE requirements for electrical Installations BS 7671.

The electrical mains supply needs to be 230V/50Hz.

The sizes/types of electrical supplies must be as detailed in System Details section of this manual. A means for disconnection from the supply mains having a contact separation in all poles that provides full disconnection under over voltage category III conditions must be incorporated in the fixed wiring in accordance with the wiring rules. This shall be located within 1m of the appliance and only serve the appliance.

The hot and cold water ‘first fi x’ pipework should be terminated 50mm above the finished floor level in accordance with the dimensions provided in the Technical Data section.

SITE REQUIREMENTS

INSTALLATION

Preparation/placing the appliance in position.

The appliance is supplied shrink wrapped on a timber installation base with the F&E cistern on top of the unit. Carrying handles are also provided in the back of the casing.

The appliance should be handled carefully to avoid damage and the recommended method is shown above.

Note: Although the above guidance is provided any manual handling/lifting operations will need to comply with the requirements of the Manual Handling Operations Regulations issued by the H.S.E. - further details are provided in Appendix C.

The appliance can be moved using a sack truck on the rear face although care should be taken and the route should be even.

In apartment buildings containing a number of storeys we would recommend that the appliances are moved vertically in a mechanical lift.

If it is proposed to use a crane expert advice should be obtained regarding the need for slings, lifting beams etc.

Before installation the site requirements should be checked and confirmed as acceptable

The plastic cover and protective wrapping should be removed from the appliance and the installation base (provided) placed in position.

The appliance can then be lifted into position in the cupboard on top of the base and the front panel removed by unscrewing the 2 screws and lifting the door up and out, ready for connection of the pipework and electrical supplies.

The feed and expansion cistern support shall be installed ensuring that the base is fully supported, the working head of the appliance is not exceeded and the recommended access is provided for maintenance - see the Technical Data section of this manual for details.

INSTALLATION

Pipework connections

The position of the pipework connections is shown opposite. The exact location dimensions are listed in the Technical Data section of this manual.

All the connections are also labelled on the appliance. It is essential that the pipework is connected to the correct connection.

Connections A and B are plain ended copper
pipe.
Connection C and D are compression fittings.
Connection E is RC½ (½ in BSPT internal)

A - 22mm Safety open vent
B - 15mm Cold feed/expansion
C - 22mm Incoming mains cold water
D - 22mm Domestic hot water
E - ½” Drain tap connection

Note: The safety open vent and cold feed/ expansion must be connected to the top up cistern using the pipework assembly provided. Do not alter or connect any pressure-relief device to the vent pipe of this water heater.

All factory made joints should be checked after installation in case they have been loosened during transit.

The fittings for the top up cistern should be installed following the instructions provided and the cistern fitted on its supports/top of the appliance.

INSTALLATION

It is normally envisaged that the top up cistern will be located in the same cupboard as the PulsaCoil BP appliance itself to maintain a dry roof space.

The cold feed/open vent pipework (as supplied) should be used to install the top up cistern directly on top of the appliance.

If it is necessary to locate the cistern in any other location, the cold feed/open vent pipework (as supplied) should be used to connect to the top up cistern and pipework site run by the installler to connect this to the appliance.

Obviously, any pipework in the roof space and the feed and expansion cistern will need to be adequately insulated to protect against frost damage.

Combined feed and open pipe arrangements must not be used.

No valves should be fitted in the safety open vent which must be a minimum of 22mm copper pipe or equivalent throughout its length.

The mains cold water supply to the ballvalve (if provided) shall be provided with a suitable servicing valve.

The overflow/warning pipe (if provided) shall have a continuous fall, be fitted to discharge clear of the building and be sited so that any overflow can be easily observed. It shall also be installed in a size and material suitable for use with heating feed and expansion cisterns in accordance with BS 5449 (e.g 22mm copper) and should not have any other connections to it.

Note: If a warning/overflow pipe is NOT provided the top up cistern should be filled from a temporary hose connection supplied from any cold water tap or from a permanent cold branch provided adjacent to the top up cistern. The temporary hose must be fitted with a double check valve and removed once the appliance is filled.

The store may fill more slowly than the feed tank. It is important to check the water level again in the cistern after commissioning and top up if necessary.


Electrical Connection - Standard Appliance

The PulsaCoil BP immersion heater wiring/ connections should be carried out by a competent person to the IEE Requirements for Electrical Installations BS 7671.

All the immersion heater terminals are suitably labelled.

Note: Do not attempt the electrical work unless you are competent to carry it out to the above standards.

Before commencing check that the power source is in accordance with the Site Requirements section of this manual and ensure that it is isolated.

1) Run the external wiring from the adjacent isolator through the service slot provided in the base of the appliance to the appropriate immersion heaters.

2) You may also run the external wiring from the adjacent isolator through the service slots provided in the base of the appliance to the scale inhibitor PCB terminals as shown in figure 1.8.

Note: The appliance pipework should be bonded to earth to comply with the IEE Requirements for Electrical Installations BS 7671.

INSTALLATION

Open the incoming stop valve and fill the domestic mains cold and hot water systems including the PulsaCoil BP appliance.

Check the water level in the top up cistern and if a ballvalve is fitted adjust if necessary.

Check the whole of the domestic hot and cold distribution systems for leaks. Fully flush and if necessary chlorinate the hot and cold water system in accordance with the recommendations in the Water Regulations and BS 6700.

Please note that the whole of the domestic hot and cold water systems including the appliance must be adequately flushed after chlorination. Failure to do this can cause damage to the exchangers/immersion heaters etc. If there are any doubts regarding this or the quality of the water being used to fill the PulsaCoil BP appliance an inhibitor such as Fernox MBI or Sentinel X100 should be added to the appliance when filling in line with the manufacturers instruction for these products.

It is most important to check that the top up tank is filled up to the water level shown on the label, if it is a manual fill model. If the optional level gauge has been provided, the level will be shown by the red float.

If a ballvalve is provided, turn down the servicing valve once the system is finally filled to the point where the warning/overflow pipe will cope with the discharge arising from a ballvalve failure.

If an overflow is not provided ensure the temporary filling hose is isolated and removed from its connection to the cold water supply.

It is essential that all systems function properly for optimum performance and if necessary, adjust the thermostatic blending valve to control the hot water outlet temperature between 50°C-55°C.

To achieve this the flow rate from each tap should be checked and a suitable number of taps run simultaneously to check the impact of this on the fl ow rate at individual taps.

We recommend that flow regulators are provided for each tap/terminal fitting to ensure that the available flow is shared evenly - See Appendix A for further details.

At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document.

This must be completed during commissioning and left with the product to meet the Warranty conditions offered by Gledhill.

Annual Service

No annual servicing of the PulsaCoil BP is necessary.

However, if required, the operation of the controls and a hot water performance test can be carried out to prove the appliance is working satisfactorily and within its specification.

If it is decided to carry out the above tests the water level in the top cistern should also be checked and if necessary topped up.

Changing Components

Free of charge replacements for any faulty components are available from Gledhill during the in-warranty period on return of the faulty part (normally 12 months).

After this, spares can be obtained direct from supplieddirect.co.uk

However, all components are readily accessible and can be changed quickly and easily by the installer using common plumbing/electrical practice.

However all maintenance work on the PulsaCoil BP appliance must be carried out by a competent trades person.

APPENDIX C

MANUAL HANDLING OF APPLIANCE PRODUCTS

Description

 Manual handling means any transporting or supporting of a load (including lifting, putting down, pushing, pulling, carrying or moving) by hand or bodily force.

Scope

This assessment will cover the largest unit within each product range manufactured by Gledhill.

For specific weights and dimensions please refer to technical data section.

Main Hazards

Vision may not be clear due to the size of the products. Adopting an incorrect method of lifting may cause injury, attempting to lift these products will require help from others. (Team lifts)

Control Measures
Manual lifting procedure
The lift, key factors in safe lifting are:

a. Balance
b. Position of back
c. Positioning of the arms and body
d. The hold
e. Taking the lead for team lifts

a. Balance - Since balance depends essentially upon the position of the feet, they should be apart about hip breadth with one foot advanced giving full balance sideways and forward without tension. In taking up this position, lifting is done by bending at the knees instead of the hips and the muscles that are brought into use are those of the thigh and not the back.

b. Position of back - Straight - not necessary vertical. The spine must be kept rigid, this coupled with a bent knee position, allows the centre line of gravity of the body to be over the weight so reducing strain.\

c. Positioning of arms and body - The further arms are away from the side, the greater the strain on the shoulders, chest and back. Keep elbows close to the body arms should be straight.

d. The hold - Before lifting ensure you have a good hold. Two handles are provided on Appliance products at the top rear side, these allow one or two persons to have a purposely-designed hold at the top of the appliance to ensure easy lifting at the top of the product.

e. Taking the lead for team lifts- As more than one person is required for these products ensure that one person is taking the lead. This may be you so ensure that each person that is helping is made aware of the weight and of the items listed within this assessment. Make sure you and any others helping know the route you intend to take that it is clear of any obstructions. Never jerk the load as this will add a little extra force and can cause severe strain to the arms, back and shoulders. If there are steps involved decide on where you will stop and take a rest period. Move smoothly and in unison taking care to look and listen to others helping with the lift. Where possible use a sack truck to move the product over long flat distances, only lift the products when necessary. If in doubt stop and get more help.

Individual capability

Individual capability plays an important part in handling these products. Persons above average build and strength will find it easier and should be in good health. Persons below average build and strength may require more rest periods during the handling process.

Pregnant women should not carry out this operation.

Persons who are not in good health should seek medical advice prior to commencing any lifting or manual handling operation.

Residual risk

Following the guidelines given above will reduce any risk to injury.

All persons carrying out this operation must be fully trained and copies of the specific risk assessment made available for inspection and use in their training process.

Further guidance on Manual Handling can be obtained from the Health and Safety Executive. Manual Handling Operations Regulations 1992.
