Luna Duo-tec MP 35-110 kW The range of high power wall-mounted boilers LUNA DUO-TEC MP consists of condensing heat generators for heating only, with power between 50 and 110 kW (at 50/30°C), plus a 35 kW power generator (80/60°C). The features of the range are high yields, high modulation ratio (1:9), modulating pump included in the hydraulic unit, simplicity of use and installation and a great number of accessories for individual and cascade installation. The main element and heart of these condensing boilers is the heat exchanger with combustion chamber and coil hydraulic system in AISI 316L stainless steel. The low water content in the exchanger means very limited thermal inertia and therefore a rapid response to the variations in thermal energy required by the system, while the stainless steel surfaces protect the exchanger from 1.35

Solutions for centralized heating systems installations risks of corrosion due to condensate. The modulating pump fully optimises the boiler’s yield, precisely adjusting capacity in order to obtain an optimal temperature difference between delivery and return. Lastly, the wide modulation range of the burner means that boiler power can be best adapted to the required thermal load. Adjustment of the various generator components is carried out by a digital PCB with latest generation double microprocessor, resulting in simple and reliable management of the boiler through a control panel with large LCD. As well as daily and weekly programming of heating and sanitary functions and the setting of climatic adjustment in accordance with the user’s criteria of comfort, the electronics system also permits easy integration with renewable energy heat generation system by programming a series of regulating parameters with which the generator can be configured to optimise its performance in relation to the type of system it will be working on. Further proof of the great flexibility of this range of boilers in highly diversified contexts.

Diagrams The following diagrams, over and above supplying a better definition of the plan of the system, permit a more detailed analysis of how the generator behaves under different working conditions. The pump capacity-prevalence curve defines the dynamic characteristics of the BAXI circulator in the hydraulic unit. It is well known that the temperature of the return water has a direct influence on the performance of a condensation boiler. At very low temperatures there is better exploitation of the latent heat and consequently better boiler performance. The diagram shows the variations in performance as a ratio between the capacity and thermal power of the specified condensation generator in function of the boiler’s return temperature. The final diagram shows the trend of the generator flue temperature in function of the return temperature. FLOW RATE/HEAD CURVE

Burner-exchanger unit The air-gas premixing unit, the burner and the primary exchanger are the components that ensure high performances from these condensing heat generators. The premixing unit is a new conception which, thanks to a new design and the double clapet technique, ensures that the burner constantly has an optimal air/gas ratio independently from the number of fan revs, keeping consumption to a minimum and always guaranteeing correct combustion and consequently a reduction in polluting emissions. On the same subject of energy saving and highest performances, this new component permits achievement of a modulation ratio of 1:9, giving the generator such great flexibility as to be adaptable to great variations in thermal load, as happens increasingly in new generation multifamily homes. In the range from 35 to 70 kW the stainless steel burner, through the internal diffuser and special micro-perforation on the cylindrical surface, achieves uniform distribution of the air/gas mixture independently of its length. In the power range of 90 to 110 kW the burner is in metal fibre. This produces a spread of very short flame for optimal heat radiation while minimising the formation of nitrogen oxides. In the range from 35 to 70 kW the primary exchanger, entirely in stainless steel, comprises one single burner/fumes chamber, which keeps the size of the generator down for high power and actually more versatile installations even in relatively restricted spaces. The two highest powered generators (90 and 110 kW) employ the dual chamber exchanger in stainless steel. The two cylindrical fumes chambers set vertically (burner chamber and condensation chamber) contain the stainless steel coils that carry the primary circuit water. In the upper chamber the hot exhaust gases transfer heat to the system return water in the coils, bringing about condensation of the fumes themselves and thus transferring the latent heat to the water, preheating it prior to its entry into the burner chamber.

Solutions for centralized heating systems installations Wiring diagram for connection to an heating system and/or to a cylinder for DHW production The boilers in the high power wall-mounted BAXI range are easily hooked up to a heating system and a sanitary water heater by means of the terminal blocks in the dashboard. The connections, with related diagram and instructions, are shown below. The pumps for the heating system (P1) and the sanitary hot water (P3) must be supplied in accordance with the diagram in the figure, inserting a relay between the boiler PCB and the pumps. The sanitary water circuit pump (P3), serving an external heater, must be connected to boiler Terminal Block M3 at terminals 4 and 5. It is always advisable to connect the sanitary circuit pump (P3) after a hydraulic separator (as shown in the figure). Connect the NTC probe for sanitary water precedence, supplied as an accessory, to terminals 9 and 10 of boiler Terminal Block M2. The sensitive element of the NTC probe must be inserted into the special housing in the heater. Regulation of the temperature of hot sanitary water and the selection of the time schedule programme can be carried out directly on the boiler control panel, as described in the manual supplied with the product. When the hydraulic separator is used, for installation of a recirculation pump on the DHW tank heater the following accessories are required: clip-in module THINK, to be installed in the boiler dashboard.

Electronics The whole range of LUNA DUO-TEC MP high power wall-mounted boilers are equipped with an extensive control panel: each key activates a specific function and the LCD simultaneously shows numbers and symbols indicating the functioning status, facilitating easy interpretation and immediate programming, adjustment and control of parameters. The boiler electronic PCB has been specially designed to run premixing condensation boilers and permits start-up, control and supervision of this kind of gas fired heat generator with view to obtaining best use of the burner for applications in the field of central heating and the generation of hot sanitary water. Indubitably the most important feature of this new generation of electronic boards is its ability to integrate different heat generation technologies through the use of small interface boards and by means of a communication protocol that allows dialogue among the various parts of the heating system. All the control, management and communications software (meaning the whole intelligent part of a heating system) resides in the boiler PCB, so the only interfaces needed for integration with other types of generator are hardware items such as extensions of connectors on the motherboard and, where required, an additional display (text knob) for the parameter programming of a complex heating system. Features: • double microprocessor: latest generation software for control of the generator, or also of a complete heating system. • management of primary circuit pump modulation by PWM controller • daily heating programme and generation of hot sanitary water • electronic thermometer • automatic troubleshooting: signalling and description of possible anomalies • incorporated climatic regulation (external probe available as optional) • automatic summer/winter changeover with external probe connected • preset for installation in cascade with control software included in the PCB • preset for installation in mixing systems (low and high temperature)

Connection of clip-in module THINK With clip-in module THINK the heater can manage either a mixing zone, controlling the mixing valve, zone sensor and pump, or a solar system by means of the sensors on the collector, tank and solar pump. This accessory is installed in the boiler dashboard. You must remove cover A from dashboard B. Raise dashboard B and hook up the flat cable between connector X50 of clip-in module and connector X41 of the boiler board, passing through the hole in dashboard B. Close dashboard B and insert the clipin module. Carry out the electrical hook-ups necessary for installation and fix the new cover C found in the pack.

Clip-in module

Solutions for centralized heating systems installations Connection of external module THINK External module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system. As for individual installations, the module external module can supply the boiler with the inlets/outlets necessary for management of a mixing zone or, alternatively, a solar system. The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted. For each individual boiler a maximum of three extension modules can be installed, one clip-in module and two external module for the management of a maximum of three mixing zones. When it is used for management of mixing zones the external module requires the presence of a remote control (see relevant section on page 20) for programming the zone control parameters. In this case the remote control may also be used as a room sensor for the mixing zone.

In the case of a mixing zone, hook up the safety thermostat between the “FX23-L” terminals and jump the terminals “EX21-FX23”. In this way the circuit pump connected to relay “QX23” is internally connected in series with the safety thermostat. Should it be necessary to use relay outlet “QX23” for functions other than those envisaged for the mixing zone, jump terminals “FX23-L”.

The external module may also be used to manage solar system by means of the boiler. In this case the connections supplied by the module are the two inlets related to the sensor on the collectors and to the sensor on the tank, whereas the outlet regards control of the solar pump (see figure). A B C

Some easy schemes to enter the THINK world Example scheme of heating circuit with 2 high temperature zones

HC2

HC1

Heating circuit with 2 high temperature zones, one zone controlled with a thermostat and one zone controlled with THINK remote control.

1) How many independent zones are in the system? There are 2 independent zones, so the 2 heating zones HC1 and HC2 must be activated. This means to set the 2 registers: 5710 zone HC1 On (factory set) 5715 zone HC2 On

2) The valve of HC1 zone is controlled by the boiler PCB, it means the relevant parameter of the QX1 terminal to which the valve is connected has to be set and it must be fixed that is the pump (or the valve) of HC1 zone 5890

4) Then it has to be set the remote control that is the address 1 and it is assigned to the zone HC1, it means: 40 (of the remote control) 42 (of the remote control)

use assignation

Room Unit 1 zone HC1

To invert the 2 zones and make 1 the zone HC2 and 2 the zone HC1, without switching the connections, it would be enough to change the setting of the parameter 5890 5890

HC1

Heating circuit with 3 high temperature zones, one zone controlled with a thermostat and two zones controlled with THINK remote controls. An external programmable module has been installed to in increase the number of the connections of the PCB and to control the 3 zone valves.

1) How many independent zones are in the system? There are 3 independent zones, so the 3 heating zones HC1, HC2 and HC3 must be activated. This means to set the 3 registers: 5710 zone CR1 On (factory set) 5715 zone CR2 On 5721 zone CR3 On

2) An external programmable module THINK has been used, so this accessory has to be set by the activation on the register 6020: 6020 FUNCTION EM1 Multi-function This setting defines the external module with the address 1 (EM1) as multi-functional.

3) The valves of the 3 zones HC1, HC2 and HC3 are controlled by the external programmable module, so the relevant parameters of the external module have to be set to define which terminals of the external module control the valves (in this contest pump and valve have the same meaning) 6030 6031 6032

INPUT H2 EM1 RT of the circuit HO3 29

5) Then the remote controls of the zone HC1 and HC2 have to be linked to the relevant zones, it means 40 (of the remote control address 1) 42 (of the remote control address 1)

use assignation

Room Unit 1 Zone HC1

40 (of the remote control address 2) use Room Unit 2 In this case it is not necessary to give the assignation, because it is automatically set in those units where the use is different form â&#x20AC;&#x153;Room Unit 1â&#x20AC;?.

HC1

Heating circuit with 2 zones low temperature controlled by remote controls THINK and 1 zone with high temperature controlled by room thermostat. To control low temperature zones it is ALWAYS necessary to use a programmable module (clip-in or external module). In this case, 2 modules are necessary. First of all, the 3 heating zones HC1, HC2 and HC3 have to be activated. This means to set the 3 registers: 5710 zone HC1 On (factory set) 5715 zone HC2 On 5721 zone HC3 On 2 programmable modules have been used, so they must be qualified by means of the activation on the register 6020 and 6021: 6020 6021

FUNCTION EM1 FUNCTION EM2

Zone HC1 Zone HC2

These settings assign the external module with address 1 (EM1) to the zone HC1 and assign the external module with address 2 (EM2) to the zone HC2. Since the safety thermostats of the low temperature zones are both connected to the terminal EX21 of the relevant external modules, this choice has to be to be set: 6024 6026

Solutions for centralized heating systems installations Connection of the interface bus for boilers in cascade THINK The interface bus is an electronic device enabling communication with and therefore the management of boilers in cascade. Thus used, the communication bus also permits remote monitoring and management of the cascade. The interface bus slot is inside the control panel of each boiler in the cascade. There are two possible positions of the accessory inside the panel: 1- If the clip-in module THINK has not already been installed in the boiler, then remove the protective cover on the back of the command panel on the boiler, place the interface bus in the relative slot and, once the electronic circuit of the boiler has been turned on, connect the interface using the cable provided to the connector of the electronic circuit X30.

Clip-in module

Solutions for centralized heating systems installations Connection of external module THINK External module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system. As for cascade systems, the external module THINK allows connection of a cascade pump (output side) downstream of the hydraulic separator, a loading pump for hot sanitary water storage and, where required, a room thermostat and sensors for flow (usually downstream of the hydraulic separator) and for return (usually upstream) of the cascade. The external module THINK can also supply another programmable outlet at 230V for system necessities. The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted. Programming of parameters regarding the cascade of boilers is carried out by means of the remote control to be installed externally (see remote control kit on page 20).

Connection of external module THINK External module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system. As for individual installations, the module external module can supply the boiler with the inlets/outlets necessary for management of a mixing zone or, alternatively, a solar system. The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted. For each individual boiler a maximum of three extension modules can be installed, one clip-in module and two external module for the management of a maximum of three mixing zones. When it is used for management of mixing zones the external module requires the presence of a remote control (see relevant section on page 20) for programming the zone control parameters. In this case the remote control may also be used as a room sensor for the mixing zone.

Solutions for centralized heating systems installations

Hydraulic separator In traditional heating system the secondary circuits, serving functioning of the ambiance terminals or an external heater for example, all set out from a common manifold that comes under the primary circuit of the heat generator. In this case the secondary system pumps have considerable influence on the functioning of the primary system pump. Reference is made to the following examples:

Non-working pumps

1 Working pumps

2 Working pumps

As you can see in the previous image when the number of DHW pumps that work simultaneously changes, the different pressure between the flow and return circuit of the primary circuit varies or the pressure that the primary pump has to win to make the water circulate from the flow collector to the return collector passing through the active DHW circuits

3 Working pumps

Hydraulic separator The function of the hydraulic circuit breaker, as suggested by its name (see the previous example) is to separate the heating circuit from the DHW circuit, making the functioning independent one from each other. The problems that can occur if this component is not used are the followings: • pumps that can not manage to provide the requested flow (installation with different pumps, small and big) . This is the case of the small pumps that have to spend to much energies to face the opposite action of the bigger ones (induced opposite ΔP) • pumps that burns (interferences between circuits can push the pumps to work out of the optimal functioning range) • warm radiators also when the pump stops (due to eddy currents developed by other active pumps). These phenomena are caused by natural circulation or circulation in the by-passes when the valves are switched off • functioning of the system for the most of time in different conditions from those established during the project, that means in the best conditions Usually ΔP is supposed to be an index to evaluate the interference between the circuits. It is, anyway, possible to fix the minimum ΔP acceptable value, that means minimum values in which the interference between circuits does not causes clear functioning anomalies, as these values depends from too many variables. The following rule is acceptable :

ΔP<0,4+0,5 mca

Interposing the hydraulic circuit breaker between the heating circuit and the circuit that includes collectors and secondary parts of the system the ΔP between return and flow becomes equal to the resistance to the flow of the hydraulic circuit breaker , which is unimportant. This value is constant and independent from the number of secondary pumps that function simultaneously in a specific moment.

Changing in the temperature due to the hydraulic circuit breaker This phenomenon is caused by the important mixing activities of the outputs between flow and return. It is clear that by adopting this installation solution, in some cases, radiators will have to be dimensioned bearing in mind the differences in temperature with the solution without a hydraulic circuit breaker. The maximum flow temperature to the radiators will therefore be T3. a) Flow rate of the heating circuit same as the flow rate of the internal boiler circuit. That is what happens in the traditional heating systems (where the pumps of the primary circuit are chosen with input that are like the ones of the secondary). In this case, the use of the separator does not change the values of the temperatures so that the radiators can be dimensioned according to the maximum flow temperature of the fluid produced by the boiler.

Solutions for centralized heating systems installations T T 1

Hydraulic separator T2

Boiler cicuit

To the secondary circuits T3

T1 T2

In this case the link between the temperatures, as anticipated above is : T1= T3 e T4=T2 b) Flow rate in the heating circuit greater than the flow rate of the internal boiler circuit

BoilerT2cicuit

T4 To the secondary circuits T4

In this second case the relationships between the temperatures of the water to the connections of the hydraulic circuit breaker are the followings:

T1 > T3 e T2 = T4 ∆Tboiler=Q/Gboiler ∆Tsystem=Q/Gsystem T2=T1-∆Tboiler

T3=T4+∆Tsystem=T2+∆Tsystem

Where Q means the output of the boilers and Gsystem and Gboiler represents the flow rate of the heating circuit and of the boiler. This is what happens in the systems with under station at distance when you prefer to keep the input value of the primary circuit to contain the expenses of the system as well as the operational expenses.

Hydraulic separator c) Flow rate of the heating circuit lower than the one of the circuit of the boiler

Circuit of the boiler

To the secondary circuis

In the third example the relationships are the following: T1 = T3 e T2 > T4 ∆Tboiler=Q/Gboiler ∆Tsystem=Q/Gsystem T2=T1-∆Tboiler

With the same meaning of the symbols. This eventuality may be favourably exploited in system with radiating panels linked with traditional boilers for raising the return temperature in the boiler above the values that involve condensation of fumes. BAXI hydraulic separators have the followingT2characteristics: • steel body painted with epoxy powders • maximum working pressure: 10 bar • equipped with automatic air vent and discharge valve • equipped with ½”F inlet/outlet sensor fixing • insulation in closed cell expanded and rigid polyurethane foam

Luna HT 5-100 kW The range of high output condensing boilers Luna HT consists of condensing heat generators for heating only , with power between 35 and 100 kW (80/60°C).The range is distinguished by high efficiency, simplicity of use and installation and a great number of accessories for individual and cascade installation. The main element and heart of these condensing boilers is the heat exchanger with combustion chamber and coil hydraulic system in AISI 316L stainless steel. The low water content in the exchanger means very limited thermal inertia and therefore a rapid response to the variations in thermal energy required by the system.

Diagrams The figures below illustrate the heating system layout and enable more detailed analysis of generator behaviour in various conditions of use. The pump flow rate-head curve defines the dynamic characteristics of the BAXI circulator inside the hydraulic group. As is known, the temperature of the return water directly influences the efficiency of condensing boilers: at very low temperatures there is better use of the latent heat and consequently improved boiler efficiency. The graph below shows the variations in efficiency, as the ratio of the flow rate to the heat output of the condensing generator specified, depending on the return temperature of the boiler. The last figure shows the trend of the flue temperature of the generator depending on the return temperature.

Dual flue system installation This type of duct permits discharge of the combustion products both outside the building and in single flues. The air intake for combustion may be placed in a different area from that of the discharge. The gaskets and screws of the previously removed from the stopper should be used for air intake connector. The 90° bend enables connection of the boiler to the flues and intake pipes in any direction thanks to the fact that they can rotate by 360°. It can also be used as an additional bend in combination with the pipe or 45° bend. (A-B) For special installations of the flues inlet/outlet ducts (B), the orienting dual flue system supplied as an accessory, can be used. This accessory, in fact, can be used to move the inlet and outlet in any direction thanks to the possibility of rotation at 360°.

Connection of external module THINK External module THINK is a device which, in a heating system run with LUNA PLATINUM boilers, supplies several programmable inlets/outlets necessary to complete the heating system. As for individual installations, the module external module can supply the boiler with the inlets/outlets necessary for management of a mixing zone or, alternatively, a solar system. The accessory is connected to the cascade of LUNA PLATINUM boilers by means of a local bus through which the information regarding the devices connected is received and transmitted. For each individual boiler a maximum of three extension modules can be installed, one clip-in module and two external module for the management of a maximum of three mixing zones. When it is used for management of mixing zones the external module requires the presence of a remote control (see relevant section on page 20) for programming the zone control parameters. In this case the remote control may also be used as a room sensor for the mixing zone.

The pumps of the high temperature zone have to be connected one to each other, and through a relè, linked to the terminal of the external module identified with QX21-N.

Parameter configuration on non-MASTERS boiler Having configured he master boiler parameters as described in the previous paragraph, proceed to configuration of the other boilers. To this purpose, connect the remote control (if not already present) to the boiler to be configured and proceed as follows. The operations listed below are repeated for each boiler in the cascade, excluding the MASTER boiler. For correct system functioning an address must be assigned to each boiler so that it can be recognised by the master boiler (the master boiler has default =1). Moreover it is also necessary to synchronise the boiler clocks with that of the master boiler. Using the control panel, access menu 3 and carry out the following settings. Menù

Power HT 45-150 kW Power HT is the range of high efficiency floor standing condensing boilers, heating only with an output from 45 to 150 kW (80/60°C) The range of boilers is distinguished by high efficiency, easiness of use/and installation and a wide range of accessories for single and cascade installations. The main element of these condensing boilers is the heat exchanger that has a combustion chamber and a stainless steel AISI 316L coils hydraulic circuit . The reduced quantity of water in the exchanger allows a small heat inactivity and so a quick answer to the changes in the heat needed by the system.

The load loss of the exchangers defines the difference of pressure, in mm of water column, between the flow and return connections of the generator. The flow rate/ head curve explains the dynamic features of the BAXI circulator used as accessory in these boilers. The performance curve presents the changing in the efficiency, as ratio between the output and input of the condensing boiler , according to the return temperature of the boiler. Finally the last graphic explains the flue temperature trends of the boiler according to the return temperature.

Solutions for centralized heating systems installations

Burner-exchanger unit The pre mixing air-gas unit, the burner and the primary exchanger are the components that allow these condensing boilers to offer high performances. The pre mixing unit is made of the Venturi pipe in the fan inlet and of the mixer that grant constantly to the burner an optimal air-gas ratio independently from the number of turns of the fan limiting to the minimum the consumptions and ensuring always the correct combustion (that means reduction of the pollutant emissions). The stainless steel burner, through the internal spreader and the special micro-perforation of the cylindrical surface, grants a uniform spread of the air-gas mixture independently from his length. The primary exchanger, totally made of stainless steel, is built with two cylindrical flue chambers, vertically positioned (burner chamber and condensation chamber). Inside the cylindrical surface there are stainless steel coils, in which run the water of the primary circuit. In the upper chamber the warm flues discharge gives heat to the return water of the system, contained in the coils, provoking the condensation of the flues themselves and giving latent heat to the water, pre-heating it before it enters the chamber of the burner.

Power HT 230-320 kW The POWER HT range of floor standing boilers (models HT 1.230- HT 1.280 and HT 1.320) is composed of heating-only condensing boilers with an output from 230 to 320 kW (at 50°/30°C). The series is made of three models and stands out for its high performance and easiness of use and installation. These high power boilers are fitted with a high efficiency Aluminium-Silicon exchanger specially designed for this type of boiler. The relatively low water content inside the exchanger reduces heat inertia thereby allowing extremely rapid responses to the frequent variations in heat demand typical of modern centralised systems. The heat insulation in glass wool minimises heat dispersion outwards.

Solutions for centralized heating systems installations Electronic control is just like that used for wall-mounted high power boilers: digital electronic circuit with double CPU fitted with large display LCD control panel offering a modulation range of 1:6. The electronics permit daily and weekly programming of heating and DHW functions as well as climatic setting and the visualisation of error messages relating to any faults. Up to a maximum of three mixing zones can be controlled by using a clip-in to be installed inside the boiler. The boiler is preset for functioning independently of the environment air (the air-flue duct is fully insulated from the installation environment), and the presence of a check valve on the air-flue circuit enables installation in cascade without having to apply an external flue shutter.

Diagrams Besides illustrating the heating system layout, the figures below enable more detailed analysis of generator behaviour in various conditions of use. The first graph shows the exchanger pressure drop, to permit correct sizing of the boiler circulator. The annual heat production in relation to outdoor temperature shows the length of time for which the boiler will use the condensing function as a percentage of the annual heating period. The lowest outdoor temperatures, considered for the size of the generator, are in fact rarely reached during the winter period; in the remaining part of the year the boiler works at lower power, achieving higher efficiency thanks to condensing. The third graph shows boiler efficiency in relation to the power output. As may be observed, at reduced power (the most frequent functioning condition of the boiler) efficiency increases considerably.

Solutions for centralized heating systems installations

Burner-exchanger unit The premixing air-gas unit, burner and primary exchanger are the components which enable these condensing heat generators to ensure high performance. In the premixing unit combustion air is combined with the gas coming from the valve to ensure a constant optimal air/ gas supply regardless of the number of revs of the fan, limiting consumption to a minimum and ensuring constantly correct combustion so as to reduce the pollutants released. This component, combined with the boilerâ&#x20AC;&#x2122;s cutting edge electronics, also helps to save energy and maximise performance achieving a modulation range of 1:6 so as to enable the generator to adapt to large variations in heat demand, as happens increasingly in new generation multi-property buildings. The burner is cylindrical and made from steel fibre with length depending on the power of the boiler. This results in resistance to high temperatures, a very short flame edge for optimal irradiation of the heat and to minimise the formation of nitrogen oxides, and a uniform distribution of the air/gas mixture along the entire modulation range. The primary, high efficiency aluminium silicon exchanger has been developed using the latest simulation techniques to optimise flows of the exhaust gas and water in the primary circuit. The special shape of the exchanger distributes the heat evenly by irradiation in the upper part of the exchanger. In the central part heat is transmitted by convection. The distance and shape of the grid of cylinders produces uniform and efficient heat transmission. The exhaust gases are condensed in the lower part of the exchanger. Here the exhaust gases, depending on the modulation, are cooled almost to the temperature of the return water of the primary circuit. This way the energy contained in the exhaust gases is used up, apart from the 1-2% of inevitable physical loss. A uniform distribution of the heat, and heat output of the exchanger is achieved by means of the water circuit. Thanks to over-sizing of the water circuit hydraulic pressure drops are reduced as are the dangers resulting from limescale obstructions. The upper part of the exchanger forms the combustion chamber.

Solutions for centralized heating systems installations Connection to a heating system and cylinder for DWH production The high-power, floor standing condensing boilers in the POWER HT 1.230 â&#x20AC;&#x201C; 1.280 and 1.320 range are easy to connect to a heating system and indirect cylinder for the production of domestic hot water. Such connection, made with reference to the technical diagram, should be performed as follows: always provide a hydraulic separator or, alternatively, a plate exchanger for the separation of the boiler circuits from those of the heating system. The KP pump (boiler pump) should be connected to the QX1 terminals of the electronic circuit situated under the top cover of the boiler. The HP pump on the heating circuit should be connected to the QX2 terminals of the circuit and the boiler pump (TLP) connected to the QX3 terminals. As regards the temperature sensors, the system flow sensor (VFK) should be connected to the terminals BX1, the tank sensor (TWF) to the TWF terminals and the outdoor sensor (ATF) to the ATF terminals. The room sensor for regulating the heated area, if present, should be connected to the FB terminal board of the circuit.

Electronics The POWER HT range of high power floor-standing boilers (from 230 to 320 kW) is equipped with a boiler electronic circuit which has been specially designed for controlling premixing condensing boilers and which permits start-up, adjustment and monitoring of this type of gas heat generator to achieve optimal performance of the burner in heating and domestic hot water production systems. The most important feature of this new generation of electronic circuits is undoubtedly its ability to integrate different heat generation technologies through the use of small interface circuits and a communication protocol enabling the various parts of the heating system to dialogue with each other. All the control, management and communications software (meaning the whole intelligent part of a heating system) resides in the boiler circuit board, so the only interfaces needed for integration with other types of generator are hardware items such as extensions of the connectors on the motherboard. Installing boilers in cascade is particularly easy, requiring merely connection of the boilers in a communication bus using the bus interface kit. The control panel has a large LCD display, by means of which the parameters of the entire heating system can be set, using a logic menu, through the various programming and control areas. All the parameters and controls are visualised by a clearly legible text message. Features

Luna SAT BAXI, specialist in boilers production, presents new heating solutions to guarantee the maximum domestic comfort. Baxi has developed the integrated system for heat recording and distribution, applying the BAXI experience on boilers in the new built-in heat-boxes LUNA SAT. Compact dimensions, energy saving, immediate information on consumption and fair costs sharing, are all guaranteed by LUNA SAT, ensuring always the desired comfort: the DHW and room temperatures can be easily regulated according to any requirements.

Recording with wireless data transmission and M-BUS LUNA SAT are provided with heat consumption meters for the wireless consumption data transmission, without using electric cables. Thanks to a digital display, the direct consumption reading is anyhow possible. To save on reading timing and respecting users privacy, consumption data can be communicated wireless by a signal sent from the heat consumption meters to the network nodes that receive and store data. Consumption data transmission made by heat meters is repeated 6 times a day for some milliseconds. This automatic reading system allows the control of the building consumptions from one single position, avoiding possible reading mistakes, quickly and with the maximum easiness.

Reading and transmission of consumption data can be done both locally and remote using the accessories available as option. network nod e

Water in heating system for housing applications In order to convey and distribute heating to each user it is necessary to use a carrier fluid: this can be, except for special application, forced-air, steam, Freon or most typically simple water. The following information refers to typical heating systems for housing application working with water up to 100째C. In these systems it is often underestimate the possible malfunctioning and/or damages that can be caused by water not appropriately treated. The aim of this information (that takes cue from Italian norm UNI-CTI 8065) is to fix some limits of chemical and chemical/physical parameters of the water circulating in thermal systems in order to assure efficiency and safety, to guarantee long term reliability and regularity of the functioning of the whole system and its components, and to achieve energy savings. Main checking to be carried out on water are: Aspect: it depends on the presence on water of sediment, suspension, or colloidal, other than of any substances diluted in it that gives immediately evident characteristics like foam, colour or turbidity. Temperature: it is a very important parameter as higher temperature speed up processes like the scale formation, corrosion, microbiologic growth etc. So it is better to know it or specify it during the design phase of the project. pH: it is a measure of the acidity or basicity of a solution. Pure water is said to be neutral, with a pH close to 7.0 at 25 째C (77 째F). Solutions with a pH less than 7 are said to be acidic and solutions with a pH from 7 to 14 are basic or alkaline. Also pH is a very important parameter in the development of scale formation, corrosion, microbiologic growth. TDS: Total Dissolved Solids is a measure of the combined content of all inorganic and organic substances contained in a liquid, and in particular the content of salts in the water. Higher levels of salt in the water also favour the development of scale formation, corrosion or sediments. It need to be taken into consideration in order to avoid design mistakes like lack of drain or water treatment. Water Hardness: it represents the sum of all calcium and magnesium ions in it. It is expressed in mg/kg of CaCo3 or in Frech Degrees (1째 fr = 10 mg/kg CaCo3). Hard water causes incrustation and scale in systems that do not have proper water treatment. Alkalinity: it is a measure of the ability of a solution to neutralize acids, and correspond to the sum of carbonates, hydroxides, phosphates, silicates, nitrates. High concentration of these cause the pH to be higher with the consequences already stated, and are generally cause of lack of adequate drain. Iron in the system: Iron in the system can cause sediments and/or secondary corrosion effects. Presence of iron caused by corrosion indicates improper electrical conductivity in the system or improper functioning of the water treatment. Copper in the system: Copper in a system can cause local dangerous corrosions. As this element is hardly present in the water, its presence is uniquely due to corrosive processes in the circuit. Chlorates and sulphates can cause corrosion in contact with some specific materials (i.e. chlorates with some stainless steel or sulphates with copper). Microbiological formation: these can be grown mouldy, algae, mushrooms in the circuits. These can directly or indirectly cause decomposition products that can generate corrosion, and smells.

During the designing of the systems it is mandatory to install all the necessary water treatment devices and to use the appropriate chemicals in order to obtain the desired characteristics of the water. Task of the manager is keeping the water characteristics within the limits, by carrying out the necessary controls and consequent corrective actions. It is necessary to provide a chemical treatment for every installation. This treatment is carried out using the correct quantity of suitable chemical reactants aimed to complete, or if necessary to substitute, the filling water physical treatment previously done. For systems with more than 350 kW (300.000 kcal/h) it is necessary to install a safety filter (the use of this kind of filter is anyway always advisable), and if the water hardness is more than 15 fr it is necessary to install also a water softener in order to keep the water within the desired limits.

Tipycal problems of an heating system The scope of heating system water characteristic limits definition is to eliminate or substantially reduce the problems related to the water of these heating systems. We can resume these problems that seriously affect the efficiency of the system or cause substantial energy losses as follows: Scale: scale formation is due to precipitation of the salts that constitute the hardness of the water, that deposit on the pipes. These formations can have different levels of hardness and cohesion. They cause a reduction of the efficiency of the system, of the reduced heat exchange, of the obstruction of the pipes, and often are responsible of the start up of corrosion process. Calcium carbonate’s and magnesium hydrate’s precipitation create unsolvable, sticky and hard deposit that have also an high heat insulating characteristic. The heat exchange coefficient of 3 mm of limestone is equal to 250 mm of steel plate: calculations show that a limestone layer of 2 mm causes an increase of 25% of consumption. Scale formation can be avoided using chemical stabilization treatments and or softening treatment by means of resin whit ionic exchange. Corrosion: generally speaking the corrosion is caused by an electrochemical process that removes the metal surface, which can in the end obtain its perforation. Corrosion is enhanced by the presence of oxygen and origins from non peculiar characteristics of the water or from non homogenous situations such as contact between two different metals, contact with solid substances, 227

scale or mistakes in the design. When we consider the metal sheets or the system pipes or the boiler pipes they do not absorb the oxygen for the Ho2 molecule but from the micro air bubbles naturally dissolved in the water. As a consequence, the steel is in contact with water and it absorbs oxygen contained in the micro bubbles an generates iron oxide (rust) with its characteristic red colour (4 Fe + 3 O2 = 2Fe2O3). Continuous oxidations lead to a reduction of the thickness of the metal, and in the end to the complete perforation. If the system on the other hand remains well protected against external environment and it is possible to avoid relevant water topping up, the oxygen content inside the system reduces progressively, in this case a partial oxidation in lack of oxygen takes place, and the result is magnetite formation (Fe3O4) with its back characteristic colour, which can prevent against possible corrosion. Deposit: deposits are the result the organic and inorganic substances unsolvable substances contained in the water. They differ from scale because they are incoherent. They are caused by the original characteristic of the water, by the atmospheric pollution (in case of system that are in contact with the atmosphere) and can generate the same problems described in case of scale. Deposit must not be underevaluated, even on recent systems (5-6 years old) and before the substitution of the boiler it is necessary to clean the system with basic dispersant, paying attention that the basic dispersant product has the necessary time to work properly in the system. In case of old systems, or when it is not clear its age, it is advisable to use a dirt separator on the return side of the system. Deposits anyway can be avoided filtrating properly the filling water, by draining properly and regularly the system and by chemically treat the water. Biological proliferation: it includes all of the organic forms of life like alga, mildews, bacteria, fungus. Their growth is fostered by light, heat and the presence of deposits. Autotrophic bacteria (i.e. iron bacterium or sulphate-reducer bacteria) are particularly dangerous, as they are the main cause of local corrosion phenomena. To prevent biological proliferation the use of biocides is advisable.

Precautions to be taken in modern heating systems According to what above described, the following precautions have to be taken in addition to water treatment, to prevent the water from getting in contact with air: • to fit the system up with closed extension vessel; • the pre-charge pressure of the system must be higher than atmospheric pressure; • to use only gas-tight materials for the system. An heating system, once completely filled up and correctly vented, should not be continuously topped up. In case it was necessary, the procedure shouldn’t be automatically carried. Experience shows that the previous issues, if underestimated, may result in serious consequences for the system as the heat generator damages or a non-correct operation of other components of the system itself. Furthermore, correct water treatment and careful system design are even a sizable advantage from an economic point of view as they result in less maintenance expenses and better global heat transfer.
