SOLAR ENERGY CONTRIBUTIONOur planet receives a significant input of solar energy each and every day. The power of this radiation in a given place is dependent on the surface temperature of the sun, the distance from Earth to the sun, weather conditions and atmospheric diffusion (dispersal, reflection and absorption phenomena).Summer and winter alike, the power of the solar radiation reaching a surface perpendicular to this radiation is approximately 1 000 W/m2. This figure will vary depending on the angle of incidence on the receiver, the intensity and the duration of exposure to sunlight.In France for example, the average quantity of solar energy received over one year is in the order of 1 115 kWh/m2.year (1 050 kWh/m2.year for Lille where the averageannual exposure to sunlinght is approximately 1 600 h to 1 550 kWh/m2.year for Nice where the average annual exposure to sunlight is 2 800 h).It is therefore very advantageous to exploit this free,non-pollutant energy to produce domestic hot water, heat swimming pools and provide heating for buildings.

PERFORMANCE OF SOLAR COLLECTORSThe solar collectors currently on offer are capabale of recovering 60 to 80% of the solar energy available in order to use it to produce domestic hot water, provide additional heating, heat swimming pools, for air conditioning or even industrial processes.

The exploitation of solar energy by De Dietrich hot water production systems is achieved by thermal conversion thanks to the glazed flat or tubular collectors. A suitable heat-carrying fluid stores up and transfers this energy to the exchanger in the solar tank where it is stored for later use.

- the most profitable domestic hot water production technology, compared with the acquisition of a traditional water heater. Purchasing a solar domestic hot water production system means an investment by making energy and financial savings.

- using solar energy means protecting the environment. This technology (which results in 1 to 1.5 tonnes less CO2 per year per family) is the only one that allows us to take effective action to reduce greenhouse gas emissions.

- choosing solar energy means liberating oneself from the rise in the cost of traditional energies.

- finally, with De Dietrich solar domestic hot water production systems, you have the guarantee of a mature, innovative and perfectly reliable solution.

4COLLECTIVE INSTALLATIONS FOR DOMESTIC HOT WATER PRODUCTION

THE PRINCIPAL CONFIGURATIONS FOR THE PRODUCTION OF DHWMaintaining a temperature level capable of guaranteeing domestic hot water requirements for collective solar production systems necessitates an additional input of energy provided by auxiliary equipment. Depending on the nature of the requirements and their location, we can consider four levels of constraints, giving us the following solutions:- Centralised production of DHW with direct distribution- Centralised instantaneous domestic hot water production

with direct distribution- Decentralised production with direct or loop distribution- Centralised solar preheatingAs far as the collection of solar energy is concerned, two differences can be noted between collective and individual installations:

- The surface area of the collectors: installation is always done according to the particularities of the site and the shade cast, but commissioning is very particular owing to the large number of solar collectors to be installed. The collectors as a whole are referred to by the term: collector field.

- The solar exchanger: the ratio to be observed between the collector surface area and the surface area of the solar exchanger is 0.2 to 0.3m2 of exchanger surface for 1m2 of collector input surface. For collector surface areas > 20m2, an additional external exchanger must be installed. However, in the case of a collective installation of smaller size (less than 20m2 of collectors), the use of a solar tank with integrated exchanger is possible.

Centralised solar storage and domestic hot water production with direct distributionIn this case, the auxiliary generator is a single item of equipment located in the boiler room close to the solar storage tank.For small installations, the exchanger is directly incorporated in the solar tank, to choose in our range of tank B/2. The back-up is either integrated in the solar DHW tank or external: by electric water heater, tank B connected to a boiler or plate exchanger maintaining the DHW distribution loop at temperature.The number and unitary volume of the tanks will be chosen according to their performance and the space available in the equipment room.For larger installations, the solar exchanger should be outside the tank. Our solutions with RSB tank + DKCS station are suitable for these types of installation, as are our FWSs for solar preheating systems with back-up outside the solar tank.

THE MAIN CANDIDATES FOR COLLECTIVE SOLAR INSTALLATIONSClients / operators

Any public collective or private company planning a solar installation.

Design consultancy/consultant engineerAny collective installation, if it wishes to take advantage of ADEME subsidies, must undergo a study performed by a qualified, independent professional like a design consultancy or a consultant engineer. They are the ones responsible for defining the constituent components of the installation and the configuration diagrams. In the case of Guaranteed Solar Results (GRS), it is up to the engineer to formalise them.

Guaranteed Solar Results (GRS)Defined at the end of the 1980s, this concept covers an undertaking on the sustainable provision of a certain predetermined quantity of solar energy available from the solar storage tank fitted to the installation.The quantity of guaranteed solar kWh must be sustainable (5 years) by the joint venture responsible for the design and

construction of the planned installation and, where applicable, for its subsequent operation/maintenance.The installation of a tracking system (CME) will allow the provision of these data on a weekly basis (or over any other period if necessary).If the forecast results are not achieved, the joint venture must implement suitable corrective measures or compensate the client for the energy deficit level observed compared with its undertakings.Exceptionally, small solar installations (less than 50m2 approximately) can be allocated a simplified GRS, which will be restricted to the implementation of energy metering (calorie meter on the solar tank outlet) and manual readouts (preferably weekly) of the useful solar kWh delivered.

InstallerThe installer must abide by the QUALISOL charter. He is responsible for assembling the installation according to the drawings and demands of the design consultancy. He can also take care of its maintenance. It is through him that the manufacturer of the solar panels takes part in the GRS.

SUBSIDIES FOR COLLECTIVE SOLAR INSTALLATIONSTo encourage solar projects, ADEME has set up:- design (decision-making) assistance mechanisms- terms on help with work (heat funds)

To find out about the terms of entitlement to these subsidies, consult the ADEME site: www.ademe.fr

PRODUCTION OF DHW ALONE

5COLLECTIVE INSTALLATIONS FOR DOMESTIC HOT WATER PRODUCTION

Centralised solar storage and instantaneous domestic hot water production (anti-legionella) with direct distribution

Centralised solar storage and decentralised domestic hot water production with direct or loop distribution

Centralised solar preheating and individual back-up

This solution can be adopted in various applications. It can be used in particular for the separate metering of the energy consumed. Distribution is done either directly or by distribution loops. The solar tank must be designed to achieve maximum water stratification, which enhances the performance of the installation. Here too, for large storage volumes, it is possible to install several interlinked or parallel tanks.The following configuration is also possible with an enamelled type B or FWS tank.In the configuration below, each apartment is fitted:- either with an electric water heater,- either with a boiler with instantaneous or mixed DHW

preparation,- or a module of distribution of energy

This solution can provide a collector field shared by a building, which preheats the individual solar calorifiers, also with their respective individual back-ups. The solar volume assigned to the installation will be the sum total of the individual volumes of all of the tanks connected to the solar loop. This solution eradicates the need for a collective boiler room and therefore its maintenance.

This particularly compact solution is made using a FWS tank equipped with a stainless steel exchanger located in the boiler room designed to allow the connection of a solar circuit and a boiler for auxiliary heating with a production or preheating DHW in instantaneous. It is a simple, maintenance-free solution, suitable for healthcare establishments, crches, schools, hotels or any other installation subject to legionella problems. Connected directly to the FWS, the solar contribution always

takes priority over the back-up and thus improves profitability of the system.

Installed in a mixed use context, the solar energy surplus to DHW production can be easily used for any kind of heating back-up (swimming pool, home) without adversely impacting DHW comfort.

INSTANTANEOUS DHW PRODUCTION AND/OR MIXED SYSTEM

6SIZING A COLLECTIVE INSTALLATION FOR HOT WATER PRODUCTION

METHODOLOGYThe sizing of a collective installation for domestic hot water production must always be done by a design consultancy competent in this area and is compulsory if the installation is to be subject to a request for a subsidy from state bodies (ADEME, Region,).You will find below the information necessary to enable you to carry out a preliminary study for such an installation, followed by costings of the principal components of the proposed installation.

Sizing methodology:A: Collect the data requiredB: Define the principal componentsC: Define the system selectedD: Optimise sizing in relation to various systemsE: Finalise the sizing of all components

Steps D and E are handled by the engineering consultancy responsible for the studyThis is used to provide initial costings and draft the specifications with the commissioning and connection diagrams.

Collecting data on DHW requirements The set point domestic hot water temperature assumed to be

constant throughout the year. The volume Vj, average daily consumption of domestic hot

water, should be estimated using the tables below or measured using a flow meter placed in the installation if it is not known.

Definition of the principal componentsFlat and tubular collector surface areaThe collector surface area determines the cost and performance of the system. In the procedure to pre-size the surface area needed, S0 is defined as follows: S0 = Vj/XS0: input surface flat collector (m2)Vj: average daily consumption of domestic hot water (l)X: volume of water (l) heated per m2 of collectors. This parameter

is dependent on the climate zone and may vary between 45 and 75.

Note: for tubular collectors, the input surface must be reduced by approximately 25% compared with flat collectors.

ConstraintsWith the collector surface area S0 thus defined, we can check:- whether the cost of the collectors matches the scheduled

investment,- whether the scheduled emplacement actually allows enough

room for its installation (see page 15). The choice of incline of the collectors depends on requirements if seasonal: 30 for heavy requirements in summer, 60 for heavy requirements in winter, 45 for use all year round.

The following correction factors should be applied if the opti-mum incline cannot be respected.One or other constraint may this cause a variation in the collector surface area initially pre-sized.The annual quantities of solar energy received in kWh/m2.day generally given for a region correspond to the optimum orientation of the collectors: southern orientation, incline 45. If the location of the collector field differs from these data, the average daily exposure to sunlight will be reduced according to the following correction coefficients:

Correction factor fiDepending on the incline of the collectors in relation to the optimum angle, this diagram gives the correction factor fi to be applied.Example: for a roof gradient of 25, the correction factor will be 0.95.The efficiency of the solar installation will be reduced by 5% compared with an ideal installation.NB: no installation of collectors with an angle of incline < 25, unless the installation is only used in summer.

Reductions in efficiency due to divergences from the ideal orientation or incline can be compensated to return to the initial value X by adding supplementary collectors.

Solar storage volumeThe storage volume is defined according to the daily maximum volume of domestic hot water consumed over the period May-August and the size of the apremises it is intended to serve.

Minimum value to be observed:

50 litres storage per m2 of collectors

Storage can also be done using several tanks, which will be interconnected. If the space for the storage volume is limited, it is necessary to reduce the solar collector surface area.

Sizing the solar exchangersTo run a solar installation in both summer and winter, it is imperative that antifreeze liquid be used as heat-carrying fluid. This fluid guarantees collector operation from -30 to 130C and protects them against frost and vapour formation. The inclusion of an exchanger in the installation is therefore essential.

There are two ways to calculate the useful output of a solar collector:

We can differentiate between two types of exchanger:

Exchanger integrated in the storage system(coil exchanger)

Method , in accordance with standard NFP 50-501

Method , in accordance with EN 12975: Exchanger outside the storage system

(plate exchanger)

To connect a solar field to a solar tank with an integrated exchanger, it is important to check the following surface area ratio: Smooth pipe exchanger: 0.2 to 0.3m2 of pipe per m2 of collectors

installed Finned pipe exchanger: 0.3 to 0.4m2 of exchange per m2 of

collectors installedThe exchange coefficient must be in the order of 100 W/m2.C

To connect a solar field to a plate exchanger, it is important to check the following surface area ratio: 0.15 to 0.3m2 of exchange surface per m2 of collectors installed.To achieve an exchange between the primary circuit (solar) and the secondary circuit (use), it is important to have a difference in temperature of 5 K to limit losses in efficiency. The output of the exchanger must be 100 W/C per m2 of collectors at flow rate (15 l/h.m2).The pressure drop caused by the exchanger must not exceed 100mbar at peak times.In these cases, the output losses are in the order of 5% (35 W per m2 of collectors) compared with the integrated exchanger.

Useful output in W/m2 at the exchanger inlet:P = (B x l) - K x (T)With B = optical factor of the collector (no unit) K = total heat transmission coefficient K of the

collector in W/m2.K I = output received by the collector in W/m2

( 1 000 W/m2 sun with no cloud cover) T = difference between the temperature of the

liquid in the collector ( 65C) and the outside temperature (25C in summer)

Useful output in W/m2 at the exchanger inlet:P = l x dk< (a1 T + a2 T2)With I = output received by the collector in W/m2

( 1 000 W/m2 sun with no cloud cover) a1 and a2 = transmission loss coefficient of the

collector in W/m2.K for a1 andW/m2.K2 for a1

dk = optical efficiency of the collector T = difference between the temperature of the

liquid in the collector ( 65C) and the outside temperature (25C in summer)

Vsto = Vmoy + 20% Vsto: storage volume (l)

Vmoy: maximum daily volume of domestic hot water consumed (l/day)

9SIZING A COLLECTIVE INSTALLATION (contd.)

The following graph gives an overview of the efficiency of the various types according to the desired collector outlet temperatures:- for the solar carpet (black, non-glazed PUR pipe) used for heating

swimming pools or ponds, the maximum admissible collector outlet temperature is 40C.

- DIETRISOL PRO C flat glazed collectors, which present an efficiency of more than 50% for utilisation approaching T = 20 at 50 K, are perfectly suitable for use in the field of domestic water heating or heating. Use under 50% efficiency at higher temperatures therefore would only pointlessly increase the solar surface areas required.

- DIETRISOL POWER tubular collectors, in which efficiency remains higher than 50% with a T of 80 K should be preferred for high temperature applications that may be found in industrial or food production processes or in solar air conditioning. They are also suitable for applications in cases of poor exposure in which the laying surfaces are limited or insufficient in relation to high requirements with a view to increasing the solar cover of the installation.

Defining the systemAn estimate of the daily DHW consumption is used to pre-size and check any installation- of the solar collector field,- of the volume of the solar tank.Depending on the surface areas and volumes thus established, it is possible to choose a system- with integrated exchanger,- with plate exchanger.It is now possible to make an initial costing of the proposed installation. In all cases, this is only a pre-sizing of the principal components. An exact sizing with profitability calculation is necessary in all scenarios.

Sizing assistance software that can be used to analyse every aspect of the process can be consulted:- SIMSOL (www.cstb.fr)- SOLO (www.cstb.fr or www.tecsol.fr)- TSOL- TRANSOL- POLYSUNDe Dietrich Thermique also offers assistance with sizing and recommendations in its DIEMATOOLS software. Consult your Regional Office. Moreover, based on the elements used for pre-sizing, De Dietrich, through the technical assistance department at head office, can:- check the feasibility of the scheduled installation,- check its hydraulic configuration as planned,- simulate potential savings.Moreover, the DIEMATEC software that we offer can be used to create hydraulic configurations in AutoCAD with a De Dietrich library.

CHOOSING THE TYPE OF COLLECTOR

Example 1 according to method and PRO C250 V/Hcollector:

I = 700 W/m2T = 30 KB = 0.81K = 4.65 W/m2 K

P = (0.81 x 700) 4.65 x 30 = 427.5 W/m2

Example 2 according to method and PRO C250H collector:I = 700 W/m2T = 30 Kdo = 0.821a1 = 3.669 W/m2 Ka2 = 0.009 W/m2 K2

P = (700 x 0.821) (3.669 x 30 + 0.009 x 302) = 455.8 W/m2

Example 3 according to method and POWER 15 collector:I = 700 W/m2T = 30 Kdo = 0.764a1 = 1.02 W/m2 Ka2 = 0.053 W/m2 K2

P = (700 x 0.764) (1.02 x 30 + 0.053 x 302) = 456.5 W/m2

10

For DIETRISOL PRO C250 flat collectors, connection in series is possible with up to 10 collectors in mounting on a roof, a terrace or in roof integration. Nevertheless, to maintain high efficiency in the battery as a whole, we recommend limiting batteries to 8 collectors.

For the installation of more than 10 collectors, the hydraulic connection must be divided into branches connected in parallel in a Tichelmann loop, each branch having a same number of collectors. Fields should be balanced.

THE DIETRISOL POWER SOLAR COLLECTORS

Tubular high efficiency solar collector, comprising 10 or 15 concentric glass pipes under vacuum, for mounting on a roof or terrace in

vertical juxtaposed mounting only, and up to 14 interlinked collectors for POWER 10, 10 interlinked collectors for POWER 15.

KEY MARKn 011-7S412R

USE

DESCRIPTION

PACKAGING

All applications for DHW or heating water production and industrial applications up to maximum temperatures of 85C.

POWER solar collectors are fitted with 1 high performance absorber designed for a glass-lined pipe with an outside coating of 9 selective aluminium/nitrite based layers.The glass tubes are hard-wearing and entirely separate from the solar circuit made of copper pipe, thus making it possible to replace them without draining the installation.The vacuum between the outside and inside pipes guarantees perfect insulation throughout the year.The parabolic reflector guarantees optimum use of solar energy regardless of the angle of the suns rays. A minimum angle of incline of 3 should nonetheless be observed to ensure adequate circulation of the fluid. The base frame is in aluminium and the integrated return pipes allow the POWER collectors to be connected on a single side (right or left) whence the necessity to construct only one feed under the roof.

1 POWER 10 tubular collector: package EG 3901 POWER 15 tubular collector: package EG 391Note: Several collectors can be delivered upright on 1 pallet

POSSIBLE HYDRAULIC CONNECTIONS

Fitting the collector circuitsCollectors are mounted in sets called batteries. In a battery, the hydraulic connection between collectors can be done in parallel to limit the pressure drops. In order to guarantee uniform irrigation of DIETRISOL PRO

C250H/V collectors, we advise limiting each battery to 8 units if connected on the same side or 10 units if connected diagonally. For optimal efficiency, collector fields of 5 to 6 collectors are preferable.

For the DIETRISOL POWER 15 collector, we recommend limiting the batteries to 10 units. (14 units for DIETRISOL POWER 10).

Below are a few hydraulic coupling configurations that help to avoid the most common design errors.

- Paralell connection of collectors DIETRISOL PRO C250V mounted vertically

- Paralell connection of collectors DIETRISOL PRO C250H mounted horizontally

- Paralell connection of collectors DIETRISOL POWER 10 or 15 mounted vertically

Balancing the collector circuitsOne of the problems often observed between the thermal performance of a solar system measured on site and the performance forecast by the calculation is often attributed to an incorrect balance of the collector field. The connection of batteries in parallel with a Tichelmann loop is tantamount to pre-balancing the installation and limits drops in pressure if the batteries are uniform.

Additional rule to be observedThe ratio between the internal of the collectors pipe and the internal of the solar panels pipe must be between 1.6 and 3.3.Nota: if it is impossible to install a Tichelmann loop, it is necessary to install flow rate regulation valves that make it easy to balance each field of collectors on the various batteries. Self-regulating adjustment valves are available, which obviate manual adjustment battery by battery.

For a large number of collectors, we recommend mounting the batteries in parallel.Below, a few configurations for the hydraulic coupling of batteries.

(1) The brackets shown for terrace mounting on page 16 allow an incline of between 20 min. and 55 max. For other inclines, it is possible to incline the base of these brackets

DIETRISOL PRO C 250 V/H collectors are designed to be installed in batteries:- up to a max. of 10 units juxtaposed in vertical or horizontal

mounting (recommendation: 8 collectors),- up to a max. of 4 units juxtaposed in roof integration (max.

recommended).DIETRISOL POWER collectors can be installed in batteries of up to a maximum of 10 units for POWER 15 or 14 units for POWER 10 (vertical mounting only).

The collector fields must be facing south or south-east/south-west, not shaded in winter when the sun is setting, with an incline between 15 and 65. For use all year round, 45 is recommended.Nota: for POWER collectors, flat mounting is possible but must nonetheless have a minimum incline of 3.

Important: For the dimension of the collector field (dependent on the mounting type selected) see page 16.

Limit on above sea level height according to snow load (EN 1991-3) (DIETRISOL PRO C250V/H)

Limit on building height according to wind load (EN 1991-1-4)

CHOICE OF TERRACE BRACKETSWe offer 2 types of terrace bracket:- For high wind and snow loads: High Load (HL) system- For standard wind and snow loads: Standard Load (SL) systemsThe graph opposite shows the height limit for installation on a building according to wind speed at the installation locations for each of the 2 types of terrace bracketIn order to ensure the stability of the whole, the support must be firmly attached to the base (3 fixing screws). If the stability of the support is not guaranteed by screw fittings, it should be given sufficient ballast to be able to deal with exposure to the wind and the ensuing stresses (edding stones may, for example, be used for this purpose) see page 18. The maximum load on the terrace must in no event be exceeded. If necessary, a specialist in statics must be consulted beforehand.

If several parallel rows of collectors have to be mounted, it is essential that you observe a minimum spacing between rows to take any shadows cast into account.The table below gives the minimum spacing (dimension x) between rows. 3 distinct uses of solar energy (seasonal priority) are specified:

Failure to observe of the dimension x means that the next row will be in the shade, thus reducing the active surface area of the battery accordingly.

The collectors are held at the bottom by a peg fixed to the inclined wide profile to allow hydraulic connection and the fitting of lateral retaining flanges to the collectors.The terrace brackets can be pre-mounted supports without the collectors. The basic packs each comprise 2 brackets (for the first

collector in a field) and single-bracket extension packs (for each additional collector in a field). The feet are interlocked at the back by stabilising crosses. The support feet are secured to a base frame by 3 screws or bolts 8mm. The brackets must be resting against the triangulation points to prevent overhangs.

The collectors are mounted on rails (screw-on profiles), which are themselves mounted on bracket feet. Each foot comprises 4 bolt-assembled profiles. To install the first collector, it is necessary to order 1 basic terrace bracket + 1 screw-on profiles pack. For each additional collector, it will be necessary to place a further order for 1 terrace extension bracket + a second screw-on profiles pack. The lower profile (rail) incorporates a wing peg to hold the collector in place during hydraulic connection and

tightening of the lateral retaining flanges. The basic bracket packs comprise 2 feet and the extension packs for one foot. In addition to the lower rail (with collector wing peg) and the upper rail (without wing), the profiles packs comprise the screws, the lateral retaining flanges for the collectors and the profile coupling parts. The bracket feet are secured to a base frame by 3 screws or bolts 8mm.

INSTALLING DIETRISOL PRO C250V , C250H SOLAR COLLECTORS ON A TERRACE,

BALLAST AND HOLDING POWER OF THE SCREWS SECURING THE TERRACE BRACKETSIn order to factor in the wind load, it is necessary, depending on the installation zone and the category of terrain (see below), to secure the structure supporting the solar collectors:- Either by installing sufficient ballast; - Or by securing the terrace brackets to their base frame.

NB: If using ballast, it will be necessary to satisfy oneself as to the roofs ability to bear this additional load (collectors included). Installation of this ballast must be done in such a way that it cannot work loose from the brackets and that all of the ballast rests on the brackets.

Definition of ballast

Sizing the retaining screws

In urban terrain: refer to the table opposite, which gives the weight of the ballast to rest on the brackets.

In extra-urban terrain on an exposed site such as an island, on the coast or at height (mountain plateau), it is necessary to apply the increase coefficient shown opposite.

The ballast weights are given according to NV65 rules for a collector incline of 65.

In urban terrain: to calculate the holding power of the bracket retaining screws, it is necessary to refer to the strength necessary per collector (equivalent to the ballast weight defined above), divide it by 3 (3 holding screws) and apply it to a screw/bolt of 8mm (locating holes in the brackets: 10mm) see table opposite.

In the same way as for ballast definition, in exposed terrain, these values should be multiplied by the increase coefficient given.

A retaining point can be a bolt or a screw in a dowel or any other retaining device handled via the 3 locating holes in the brackets.

The holding power of the bracket retaining points is defined according to the EN 1991 standard for a collector incline of 65.

FITTING THE SUPPORTS ON A ROOF TERRACE

PENETRATION OF PIPES THROUGH THE ROOF

The collector fastenings must enable it to withstand the effects of normal loads of wind and snow. Two possible connection

techniques between the collector supports and the roof are detailed below.

Pipes must be fitted in such a way as to prevent any infiltration of run-off water into the building.

The collector support is fixed to a concrete footing covered by a watertight metal hood. The concrete footing is made in accordance with the standard.

Installation of waterproofing flashing to a height of 15cm on the concrete footing is done in accordance with the standard.See prevailing regulations.

The support can be held in place by anchoring the base of the support in a concrete mass providing ballast, placed on the waterproofing using a distribution material (expanded polystyrene, for

example). The concrete mass must be removable as a matter of course, without the need for lifting plant, to allow the waterproof coating to be repaired whenever necessary.

The pipes carrying the heating-carrying fluid are fitted horizontally through a vertical wall coming out inside the building. They are fitted using a metal sleeve sealed into the vertical wall situated above the flashing. The sleeve is terminated by

a edge forming a drip groove around its entire periphery.A waterproof collar is fitted to the pipe carrying the heat-carrying fluid. It covers approximately 3cm of the sleeve.

In this case, pipes must be fitted using a sleeve and a plate.The top part of the sleeve is at least 15cm above the covering protection.

A waterproof collar is fitted to the pipe carrying the heat-carrying fluid. It covers approximately 3cm of the sleeve.

INSTALLING DIETRISOL PRO C250V , C250H SOLAR COLLECTORS ON ROOF

Given the thicknesses and installation options, as well as the colour of its frame, the in-roof mounting of the DIETRISOL PRO C250V/H collectors that we offer is designed in every way for optimal integration in the roof while retaining the advantages of on-roof mounting, i.e.:- The collectors are always accessible: the hydraulic components

and sensors can be easily checked and/or replaced where necessary at any time;

- Mounting is not reliant on the roof incline and installation remains relatively straightforward as it does not require any knowledge of roofing;

- The constraints caused by the expansion of the materials have no influence on the watertightness of the building over time, contrary to roof-integrated installations with large collector fields, a great deal of layering of plates, repeated jointing subject to very low temperatures in winter and very high temperatures in summer.

SIZING OF THE COLLECTOR FIELD

MOUNTING OF COLLECTORS ON ROOF

It is important to know the space needed for mounting a field:- to ensure the correct laying of the collectors, and its connections- to ensure adequate access to the collectors at all times.

We can supply integration packs for roofs or any other support:- With mechanical roofing tiles and for roof inclines > 21- With flat tiles and roof inclined at more than 21- With canal tiles for roofs with incline > 15

The in-roof integration of solar collectors requires the installation of a CSTB-approved roof liner which must extend down as far as the gutter and overlap the area covered by the integration pack itself by at least 50 cm.

Installation of these packs must be done by a roofing professional in order to ensure correct mounting, particularly as regards the watertightness of the roof.For maintenance questions, we recommend limiting in-roof mounted collector fields to small fields, which can be accessed at all times, and preferably with vertical collectors. In other cases, it is preferable to opt for on-roof mounting: see the advantages of such mounting on page 20.

Nota: the roof battening must be in good condition to be capable of bearing the weight of the collectors.

INSTALLING DIETRISOL PRO C250V , C250H SOLAR COLLECTORS IN ROOF INTEGRATION,

The collectors are mounted on the existing battening with the installation of specific battens to hold these collectors in place. The collector field must be mounted, hydraulically connected and pressurised before closing the roof using the metal sheets provided.The basic packs allow for the integration of one collector. For any additional collectors, the extension pack is needed. During mounting, some of the parts contained in the basic pack should be used at the beginning of the field and the rest to finish the collector field.The use of internal ridge tiles with the lower part of the pack (lead flap covering the tiles) is imperative in the case of a roof with

highly contoured tiles. The flap forms 230mm of roofing and does not exist in the packs for flat tiles (the latter do include, on the other hand, the flashings in the basic packs).

Note:We advise against integration mounting for roofs covered with highly contoured (canal) tiles and gradients of between 15 and 21 for aesthetic reasons as the lower and upper roofing sheets take up nearly 800mm.

HYDRAULIC CONNECTION

COLLECTOR PIPES (PRIMARY CIRCUIT)The connection pipes between the collector field and the exchanger in the solar tank or the DKS/DKCS station must be routed with a constant downward slope as direct as possible.The materials used must be compatible with the heat-carrying fluid.We recommend the use of copper pipes with brass valves or non-galvanised steel pipes (galvanised pipes and valves and graphite gaskets should be avoided) or the duo-tube, which can be delivered as optional equipment (synthetic materials should be avoided owing to the high temperatures).- welds must be done with strong brazing filler metal without flux

(L-Ag2P or L-CuP6),- union connections can only be used if they are resistant to the

heat-carrying fluid at pressure (6 bars) and at temperature (-30C to +180C),

- hemp should only be used in combination with mastics resistant to the high temperatures and pressures,

- a manual air vent must be fitted at the high point,

- the installation of a safety valve and an expansion vessel is compulsory.

Thermal insulation of the pipesAll pipes must be insulated. To limit heat losses, we recommend making the conduits as short as possible (< 5 linear metres per m2 of collectors installed).The pipe lagging must have the following characteristics:- withstand temperature variations of between -30 and 180 in the

collector zone,- withstand UV and bad weather conditions on the roof,- be uninterrupted and of a thickness at least equal to that of the

pipes with a min. thermal coefficient h of 0.04 W/m2.C.- outdoors, it must be protected against mechanical deterioration,

UV rays and birds by additional reinforcement made of a sheath in aluminium sheeting sealed with silicone,

- recommended materials: Armaflex, Aeroflex SSH, glasswool.

Below are the values of the thermal coefficient h for various insulating materials:
