3 CHOICE OF DHW PRODUCTION PRINCIPLE The domestic hot water system must be chosen in fu knowedge of the facts, in order to ensure continuous DHW avaiabiity at the desired fow rate and: - In the individua residence, at the desired temperature in order to ensure the comfort wished for by the user - for those estabishments requesting it, at the temperature required to avoid proiferation of egionea and set by the DUT. One of the recommendations for heath institutions, schoos, pubic buidings, etc. is that the DHW production be instantaneous, i.e. without storage, and that the return temperature of the recircuation oop on the pate heat exchangers be maintained at above C. FW C FW_F001 The estimate of the DHW requirement is important for defining the system and its components. Our FW and other caorifier products respond to these prerogatives: - The FWS combines instantaneous DHW production with primary storage in the same voume. - The FWPC, FWPS and FWP are defined for instantaneous DHW production. DHW production using pate heat exchangers Instantaneous DHW production Semi-instantaneous DHW production FW FW FW_F0015 FW_F0015 Soution invoves storing the domestic hot water immediatey or rapidy meeting arge needs and is therefore subject to the constraints reating to egionea: minimum storage temperature, superheating cyce, periodic ceaning of the tank, etc. It is aso appicabe for repacement of components in boier rooms and our products are entirey suitabe for this purpose. For new instaations or major renovations, we advise against semi-instantaneous systems with DHW storage in favour of instantaneous DHW production systems with primary storage (soution ). Benefits of instantaneous DHW production with primary storage - Aso enjoy the advantages of semi-instantaneous DHW production, incuding reduced generator power and/or aowing it to shutdown or at east decrease its temperature when DHW is not being drawn, Advantages of our product soutions - deivers significant productivity gains in DHW production by: imitation of the Primary inet temperature required to 0 C, a primary return temperature aowing condensation of the boier and/or effective integration of renewabe energies in the system (FWPC/FWPS), - Removes any risk of the presence of egionea in the DHW distribution, whie ensuring that a suitabe quantity is avaiabe at the desired temperature. precise contro of the system with Cass A, ow consumption, moduating primary pumps, having energy efficiency index EEI < 0.. Note: In this document, we wi ony describe this type of instantaneous DHW production system athough, of course, we have products for a types of instaation.

4 CHOOSING THE DOMESTIC HOT WATER CALORIFIER The domestic hot water caorifier must be chosen in fu knowedge of the facts in order to ensure permanent DHW avaiabiity at the desired temperature. It is therefore important accuratey to determine the DHW needs necessary to meet this requirement, which depends argey on the number of peope iving in the home and their consumption habits. It wi aso depend on the risk of egioneosis, which woud direct the choice towards a caorifier with instantaneous DHW production (soution we recommend). Beow are a number of points which may hep you in this choice : DETERMINING YOUR DOMESTIC HOT WATER NEEDS Determining these needs wi condition : - The choice of the DHW caorifier s capacity; - The power of its exchanger; - And possiby the power of the generator with which it is combined. Actua needs wi therefore have to be determined for a given temperature over a given duration (hour/day) and the peak fows (itre/minute) assessed according to DHW use at a given moment. In coective housing, it wi aso mean factoring in simutaneous use. METHODS FOR DETERMINING YOUR DHW NEEDS Using the DHW Needs software avaiabe in our DIEMATOOLS offer This software (or any other software which you may have acquired) wi offer you an effective guide in assessing your needs. Other methods - Using the tabes beow, it is possibe to approximate your daiy domestic hot water needs. Important: To determine the capacity of the DHW caorifier, it is necessary to factor in any peak fows caused by simutaneous use at different draw-off points in addition to these daiy needs. As for the cacuation of the instaation, this wi have to be made in accordance with prevaiing standards.

5 A 0 6A CHOICE OF THE DHW PRODUCTION SYSTEM AND TYPE OF CALORIFIER CONNECTION PRINCIPLE OF A BOILER (OR CASCADE OF BOILERS) TO A FWPC, FWPS OR FWP CALORIFIER To ensure optimum operation of the FWPC, FWPS or FWP with a boier, it is essentia to decoupe the caorifier circuit from the boier; this can be done through a disconnecting cyinder which wi provide tota satisfaction for the operation of the FWPC, FWPS and FWP. By contrast, there wi be a tendency to request repetitive heating of the boier if it is not continuousy maintained at the DHW setpoint temperature to ensure water draw-off or to maintain the temperature of the recircuation oop. Soution not recommended with FWPS or FWPC FW FW_F0016A Since our boiers have distinct features for heating and DHW production, with owering and/or moduation of the temperatures according to the demand, we recommend the instaation of primary storage in pace of a disconnecting cyinder in order: - to aow the operation of the boier at ower temperatures for heating than for the production of DHW - to aow and to favour condensation with the FWPC, FWPS and FWS - to aow shutdown at night or outside of periods when DHW is being drawn-off from the boier, to reduce the consumption for maintenance - to avoid frequent or repetitive restarts during very ow drawoff of water and/or for temperature maintenance in the recircuation oop. FW FW_F0016A Optimisation of condensation To ensure the DHW needs by reducing as much as possibe the time for the boier to raise the temperature and to condense we recommend the instaation of a reversa vave with thermostatic contro on the boier outet, which wi switch over this vave to the top of the primary storage when the inet temperature to the vave has reached the DHW setpoint of the boier. 0 C FW FW_F00 Recommended soution This principe (estabishment of a primary storage) wi be adopted for a these configurations in coective housing, retirement homes, hospitas, etc., with a DHW setpoint of 0 C for the boier, in order to both ensure a secondary outet temperature to the DHW heat exchanger of 60 C and, above a, to protect the heat exchanger from ime scae deposits that argey occurs at temperatures greater than 5 C at the secondary eve. This ow temperature of 0 C impies a sight oversizing of the pate exchanger but is offset by gains in terms of energy consumption and maintenance. DEFINITION OF THE COMPONENTS OF A DHW PRODUCTION SYSTEM To ensure correct functioning of the system and to meet the needs of the instaation, the components shoud be defined as foows: DHW caorifiers FWPC, FWPS, FWP and FWS: Primary buffer voume: Refer to the maximum instantaneous fow rates given on To be defined as a function of the boier power; see foowing page 1. page. Boier output: The boier power shoud be equivaent to at east that of the DHW caorifier seected. The boier wi aso be sized to ensure that the heating and DHW needs are met. Remember: Our boiers are moduating and thus incorporate output reduction aowed by the primary storage on the caorifier. 5

6 CHOICE OF THE DHW PRODUCTION SYSTEM AND TYPE OF CALORIFIER Definition of the buffer voume to be associated with the FWPC, FWPS and FWP caorifiers The tabe beow indicates the advised primary buffer voume to insta according to the power of the pate exchanger or DHW fow required. This voume takes account of the boier connection to our buffer tanks in the PSE range (see page 15) either at points with zone reversa vave as recommended above, or on the midpoint connection for the boier contribution.

This aows condensation to be optimised for the boier and thus provides energy savings of up to % more than for a conventiona instantaneous DHW production. Thanks to the moduating pumps fitted to our FWPC, eectrica consumption is aso reduced by more than %. Couped with our condensing boiers, this provides the most economic instantaneous DHW production that can be instaed in ow energy consumption buidings, without risks to heath and with simpe maintenance and easiy accessibe use. System optimisation 1 1 C0 ECO 0 C PSE AD1 6 EC FWPC 0 8 FW_F0018A The reversa vave with its sensor (package EC optiona, see page ), connected on the outet of the FWPC caorifer, aows: - Optimisation of the stratification in the bottom of the buffer voume, - to promote condensation during restarts of the DHW heating - avoidance of reheating of the bottom of the buffer tank by the recircuation oop. Key: see page 15 6

7 DHW PRODUCTION WITH CONDENSING BOILER AND RENEWABLE ENERGIES 1 1 THE USE OF RENEWABLE ENERGIES DIRECTLY REDUCES THE VOLUME OF THE BOILER S PRIMARY BUFFER FWPC caorifier + reversa vave (package EC 680), optiona, see page C0 ECO 1 1 C0 ECO 0 C C PSE PSE AD1 AD EC681 EC680 AD1 10 AD 5 EC680 6 FWPC PGA8 10 CAN BUS 6 FWPC AD 6 CCI V * 11b * OU 11a 0 PS 11b 0V Hz 0 11 DKCS a 8 0V Hz 1 8 Diemaso A FW_F001A DKS The boier is connected on the buffer tank with a boier return on the ower voume corresponding to the renewabe energy contribution zone. The upper part of the storage tank (DHW boier sensor in the upper part, outside the renewabe energy zone) aows optimum functioning of the FWPC/boier combination as previousy described, whie aowing a ow temperature renewabe energy contribution of the soar or heat pump type to the bottom of the buffer voume. The cod return (0 C) from the FWPC aows, via the -way reversa vave (package EC optiona), a renewabe energy contribution in a scenarios in the event of water draw-off. This soution is used for a renewabe energy contribution that is rapid and higher in temperature because of the reativey ow voume to be heated and that activey contributes, in a simpe way, to temperature maintenance of the recircuation oop which often represents a significant yet poory identified source of energy consumption. SOLAR ENERGY ON A SPECIFIC DEDICATED BUFFER VOLUME FWPC caorifier + reversa vave (package EC 680) and preheating sensor (package EC 681), optiona, see page * - DHW sensors suppied: - with FWPC - with DIEMASOL reguation 1 FWPS DHW caorifier 1 C0 ECO 0 C * - DHW sensors suppied: - with FWPC - with DIEMASOL reguation Key: see page 15 PSE AD1 * PSE 10 6 FWPS * 11b 0V Hz 0 DKCS a FW_F001A FW_F000A This soution invoves connecting the FWPC (or FWPS) directy to the buffer voume of the boier and connecting the primary soar tank in series to the renewabe energy zone of the boier buffer voume. Note: An expansion voume is not recommended for a renewabe energy contribution with heat pump. The dedicated renewabe energy voume in the boier buffer tank being sufficient for the proper functioning of the system. In this case, the boier s DHW sensor wi have a dedicated voume (at the top). In a other cases, the boier s DHW sensor remains in the renewabe energies voume. This soution invoves connecting the FWPS to the upper part of the boier buffer voume and connecting the primary soar buffer tank in series to the renewabe energy zone of the soar buffer voume. Given the ow temperature (0 C) at the outet of the FWPS exchanger, the soar contribution wi be amost continuous, even with very itte sun. This soution aows passage through the soar buffer voume to recuperate soar energy if it is contributed or, if there is no soar contribution, short-circuiting of this tank to go directy to the boier buffer voume (boier DHW sensor at the top of the renewabe energy zone).

The soar circuit is connected to the ower part of the tank for DHW preheating (or DHW heating if the soar back-up is insufficient). A heating circuit can be connected to S1/S for a swimming poo, for exampe. The FWS can operate without a renewabe energy input (diagram on p. 1) or with renewabe energy contribution to its buffer voume (diagram opposite) or with a specific soar buffer voume at the bottom of the FWS (see FWPS diagram, p. ).

This soution is reserved for repacements of existing conventiona boiers or heat networks. Management of the primary buffer tank is ensured by the boier s DHW sensor ocated in the bottom of the buffer tank. The buffer tank pump shoud be sized according to the usefu power of the boier, to ensure the setpoint temperature at the boier outet. Key: see page 15 8

14 INSTANTANEOUS DHW CALORIFIERS FWS INSTALLATION WITH FWS CALORIFIERS CONNECTED IN PARALLEL Key: see page 15 FWS_F0006A The FWS connects to the boier ike a caorifier with coi. The boier reheats the hot water storage voume, which then provides heating of the DHW exchanger for instantaneous DHW production. The DHW sensor circuit is paced in the ower 1/ of the FWS caorifier, for which the set point shoud be adjusted to 10 K above the desired DHW temperature at the caorifier outet. The storage voume compensates for ow usage and for the reviva time of the boier during the times of argest demand. The choice of boier power shoud be made with respect to the t that it aows.

16 INFORMATION ON THE PREVENTION OF SCALDING BY DOMESTIC HOT WATER AND THE DEVELOPMENT OF LEGIONELLA To restrict the deveopment of bacteria, the temperature of the hot water distributed must be at east 60 C on eaving storage and, if the instaation incudes a recircuation oop, the return water RECOMMENDATION REGARDING SCALDING Scading caused by domestic hot water is a common accident which has serious consequences, particuary because of its potentia extent. Around 15% of scads are thought to be caused by the domestic hot water temperature being to high, occurring principay in the bathroom. temperature must be at east C. In a cases, users must be protected against the risk of scading at the draw-off points where the temperature of the water drawn off must not exceed C. 1. In order to imit the risk of being scaded : - in rooms intended for abutions, the maximum temperature of the domestic hot water is set at C at the draw-off points ; - in the other rooms, the maximum temperature of the domestic hot water is imited to 60 C at the draw-off points ; - in the kitchens and aundries of estabishments open to the pubic, the temperature of the water distributed may be raised to a maximum of 0 C at certain points which are indicated by specia warning signs.
