PRESENTATION OF THE RANGES

The independent DHW calorifiers in the ranges BP… and BC… are used to produce domestic hot water both in individual and collective housing and in commercial or industrial premises.They are made of very thick sheet steel allowing a maximum operating pressure for domestic hot water :• Of 10 bar for BP 150 to 500;• Of 7 bar for BC 150 to 500.Their interior is protected by food quality standard high quartz content vitrified enamel and by a magnesium anode.BP/BC DHW calorifiers are fitted with an exchanger in the form of an enamelled coil with a larger exchange surface for the BP… than for the BC…They are insulated with injected polyurethane foam with 0% CFCs, 50 mm thick.

The unit is completed by a casing in painted sheet steel in a white finish with yellow covers.Note :The choice of a BP… or BC… DHW calorifier will be made according to its intended use as well as according to its volume and its maximum operating pressure (7 or 10 bar) :- if the flow over 10 minutes (l/10 min) is the main criterion,

both ranges, BP… or BC, offer equal performances;- if, on the other hand, continuous flow (l/h) is the main

requirement, one or other DHW calorifier will be selected according to the larger exchanger on the BP… than on the BC at an equivalent capacity.

Like BP/BC… DHW calorifiers, B 650/800 and 1000 DHW calorifiers are used to produce domestic hot water in collective housing as well as in industrial or commercial premises.They are made of very thick sheet steel allowing a maximum operating pressure for domestic hot water of 10 bar. Their interior is protected by food quality standard vitrified enamel with a high quartz content. This protection against corrosion is further reinforced by a Correx® “self-adapting” current anode with a practically unlimited life span.They are fitted with an exchanger in the form of a large enamelled coil.

The casing, in beige and grey on the B 650/800/1000, is constructed using rigid shells in polyurethane foam with 0% CFCs ; this class M3 casing allows the use of these DHW calorifiers in establishments open to the public and can be put in place once the tank has been installed and connected.

➪ Other methods- Using the tables below, it is possible to approximate your

daily domestic hot water needs.

Important : To determine the capacity of the DHW calorifier, it is necessary to factor in any peak flows caused by simultaneous use at different draw-off points in addition to these daily needs.As for the calculation of the installation, this will have to be made in accordance with prevailing standards.

Note : These tables do not cover multi-jet showers (� 50 l/min) or “spa” type bathtubs

CHOOSING THE DOMESTIC HOT WATER CALORIFIER

The domestic hot water calorifier must be chosen in full knowledge of the facts in order to ensure permanent DHW availability at the desired temperature.It is therefore important accurately to determine the DHW needs necessary to meet this requirement, which depends largely on

the number of people living in the home and their consumption habits.Below are a number of points which may help you in this choice :

Determining these needs will condition :- The choice of the DHW calorifier's capacity;- The power of its exchanger;- And possibly the power of the generator with which it is

combined.

Actual needs will therefore have to be determined for a given temperature over a given duration (hour/day) and the peak flows (litre/minute) assessed according to DHW use at a given moment. In collective housing, it will also mean factoring in simultaneous use.

DETERMINING YOUR DOMESTIC HOT WATER NEEDS

This software (or any other software which you may have acquired) will offer you an effective guide in assessing your needs.

Differential control system for controlling the load pump - Package EC 320Generally, the domestic hot water temperature is controlled by a control system or a domestic hot water priority module, which is integrated in the boiler control panel and operates the load pump. When the boiler does not incorporate such a device, the differential control system

opposite is used to regulate the domestic hot water temperature. This control system is mounted on the wall and its bulb is introduced into the housing between the tank and the insulation.

Anode AM 7

Inert electrical anode “with self-adapting current”Package AJ 38 : for BP/BC 150 to 300Package AM 7 : for BP/BC 400 and 500

“Titan Active System” kit (for DHW calorifier combined with a boiler fitted with the DIEMATIC 3 control panel) - Package EC 414The self-adapting current anode consists essentially of a titanium, platinum-coated rod powered at low voltage. Its advantage over a traditional magnesium anode is that the material is free of wear. Therefore it does not need to be monitored as its life span is practically unlimited. The self-adapting current anode is mounted in the lateral flange, in the place and instead of the magnesium anode ; for BP/BC 200 to 500 DHW calorifiers with 2 anodes, the 2nd anode should also be removed and the opening plugged

(kit delivered with the anode). The imposed current anode is delivered with a cable 3.5 m long and a transformer which can be plugged into a 230 V socket, to be fitted close to the DHW calorifier.

Important : The self-adapting current anode is not compatible with the installation of a shielded electrical resistor.

on flange Ø 117 mm (BP/BC 400, 500)- 4.5 kW multi-voltage, shielded : Package EC 413

These resistors are fitted to a flange in the place and instead of the existing lateral flange. They are equipped with a safety thermostat and are powered independently of the DHW control system on the boiler circuit.NB : When the DHW calorifier is equipped with such a resistor, it is necessary to fit a 3-bar safety valve to the primary circuit. This valve must be placed between the exchanger and the gate valves in the DHW calorifier.

Important : Fitting a “shielded” electrical resistor is not compatible with using a “self-adapting current” anode. If fitting a steatite resistor, on the other hand, the installation of a “self-adapting current” anode is essential to guarantee sufficient anti-corrosion protection in the tank.

As a general rule, the DHW calorifier can be placed to the right or left of the boiler according to the details given in the technical instructions for the boiler. The connection kits include an air vent, a non-return valve, a load pump (or reversal valve for package EA 124 and EA 120) and all the pipes required to make the connection.Note : The hydraulic specifications of the load pumps provided with these connection kits make it possible

to reach primary flow values of between 2 and 3 m3/h depending on the pressure drop in the boiler connected to the DHW calorifier.A

INFORMATION REQUIRED FOR INSTALLATION

ELECTRICAL CONNECTIONSGenerally, the DHW calorifiers are managed by a control system incorporated in the De Dietrich boiler control panel. In this case, a domestic hot water sensor with a connection cable is delivered as optional equipment or with the control system. This sensor is inserted into the housing between the tank and the insulation (BP/ BC) or the sensor tube (B 650, B 800-1000) provided for this purpose in the DHW calorifier.If using a boiler without a domestic hot water control system incorporated in the control panel, you should fit the option :

“Differential control system for controlling the load pump” which controls load pump operation according to the domestic hot water temperature selected.The “electrical resistor” and the “imposed current electrical anode” equipment (options for BP/BC…) are connected sepa-rately.

EXAMPLES OF INSTALLATIONThe purpose of the diagrams represented is to facilitate the drawing up of the quotation by the installer. They are given as examples. Other connections are possible. It is necessary to abide by the codes of practice and prevailing regulations.N.B. : In accordance with safety rules, a calibrated, sealed safety valve (at 7 or 10 bar depending on the type of DHW calorifier) must be fitted to the calorifier's domestic cold water inlet. We recommend hydraulic safety units with membrane.

When the heating installation includes a 3- or 4-way mixing valve, the exchanger must be connected between the boiler and the valve and must be as direct as possible. To improve efficiency, the independent DHW calorifier must be positioned as close as possible to the boiler and the connecting pipes must be insulated. The DHW calorifier can be placed to the right or left of the boiler.NB : To connect the domestic hot water, a sleeve made of steel, cast iron or any other insulating material must be interposed between the hot water outlet and the distribution pipes to prevent any corrosion to the connections if these pipes are made of copper.

(*) Note : the unit (53, 9, 55, 17) can be replaced to your advantage by a membrane safety unit 30, as long as you respect the following obligations :- The safety unit and its connection to the DHW calorifier must

be of the same diameter as the cold water supply pipes on the calorifier's domestic circuit (a minimum of 3/4" up to 300 litres et 1" over 300 litres);

- The level of the safety unit must be lower than the level of the cold water inlet (see below);

- The drainage pipe must have sufficient continuous gradient and its cross-section must be at least equal to that of the safety unit outlet opening (to avoid hindering the flow of water in the event of overpressure).

INFORMATION REQUIRED FOR INSTALLATION

Installation of 2 independent BP/BC… or B… DHW calorifiers and a boiler

a) Parallel hydraulic connections - primary (exchangers) and secondary (DHW)

It is necessary to ensure that all parallel hydraulic connections, primary and secondary, are correctly balanced.

This type of connection is recommended when you want to give priority to the continuous performance of the calorifiers. It also allows operation with a single DHW calorifier when this is sufficient.

Emplacement of the control system sensor :The control system sensor will be placed in the DHW calorifier which can be allowed to operate alone or in the DHW calorifier connected to the circulation loop.

Note : It is advisable to fit a control system for the domestic hot water temperature (mixer tap) on the calorifier outlet, as a fault in the hydraulic balance of the circuits may lead to overheating in a calorifier not fitted with the control system sensor. (It is also necessary to ensure that the reverse phenomenon does not occur, i.e. insufficient heating in the same calorifier).

b) Hydraulic connections - primary (exchangers) in parallel - secondary (DHW) in seriesThis type of connection is recommended when you wish to maintain maximum performance of the DHW calorifiers, avoiding any mixing at the calorifier outlet due to domestic hydraulic circuits not being correctly balanced.

Emplacement of the control system sensor :The control system sensor will be placed in the DHW calorifier A .Note : It is necessary to fit a device to control the domestic hot water temperature (mixer tap) on the DHW calorifier outlet B. Apart from a hydraulic balance fault on the primary circuits

which may lead to overheating on calorifiers B not fitted with the control system sensor, the serial connection of the secondary circuits may lead to the need to reload the calorifier A whilst calorifier B is still at temperature.

To restrict the development of bacteria, the temperature of the hot water distributed must be at least 60 °C on leaving storage and, if the installation includes a recirculation loop, the return water temperature must be at least 50 °C. In all cases, users must be

protected against the risk of scalding at the draw-off points where the temperature of the water drawn off must not exceed 50 °C.

DE DIETRICH THERMIQUESimplified Share Company with registered capital of 22 487 610 d57, rue de la Gare - F-67580 MertzwillerTel. +33 (0)3 88 80 27 00 - Fax +33 (0)3 88 80 27 99www.dedietrich-thermique.fr

INSTRUCTION REGARDING SCALDINGScalding caused by domestic hot water is a common accident which has serious consequences, particularly because of its potential extent. Around 15% of scalds are thought to be caused by the domestic hot water temperature being to high, occurring principally in the bathroom.

1 . In order to limit the risk of being scalded :- in rooms intended for ablutions, the maximum temperature of the

domestic hot water is set at 50 °C at the draw-off points ;- in the other rooms, the maximum temperature of the domestic

hot water is limited to 60 °C at the draw-off points ;- in the kitchens and laundries of establishments open to the

public, the temperature of the water distributed may be raised to a maximum of 90 °C at certain points which are indicated by special warning signs.

Example 1

INSTRUCTIONS REGARDING LEGIONELLA IN STORAGE SYSTEMS AND DISTRIBUTION NETWORKSLegionella is caused by the inhalation of water spray contaminated by legionella. Water temperature is a significant factor in preventing the development of legionella in distribution networks as the Legionella bacterium multiplies significantly in water presenting temperature of between 25 and 43 °C.In order to limit the risk connected to the development of legionella in domestic hot water distribution systems to which draw-off points which may be at risk at likely to be connected, the following requirements must be respected when using domestic hot water production and distribution systems and during the 24 hours preceeding their use :• When the volume between the distribution point and the

most distant draw-off point is more than 3 litres, the water temperature must be higher than or equal to 50 °C at all

points in the distribution system with the exception of the final supply pipes. The volume in these final supply pipes must be as low as possible and at all times less than or equal to 3 litres ;

• When the total storage volume is higher than or equal to 400 litres, the water contained in the storage equipment, excluding preheating calorifiers, must :

- Always be at a temperature higher than or equal to 55 °C at the equipment outlet ;

- Or be raised to a sufficient temperature at least once every 24 hours. Annex 1 gives the minimum water temperature maintenance time to be respected.

Annex 1 : minimum duration of the daily increase in the water temperature in storage equipment, excluding preheat-ing calorifiers
