8 ICONE Domes c Hot Water produc on (D.H.W.) Hea ng Water Produc on GUIDE WHEN CHOOSING A CALORIFIER A calorifier is an indirect water hea ng appliance (i.e. one that features at least one heat exchanger) which accumulates heat so as to handle consump on rates that may vary greatly over a period of me, while also limi ng the power used by the generators. grey STOCK AVAILABILITY STOCK AVAILABILITY Grey highlighted products are available in stock and can be dispatched in 1-5 working days. Cordivari offers a wide and varied range of calorifiers and buffers, to provide the most suitable product to any need and also allow simultaneous use of more energy sources. Calorifiers with tradi onal boilers: These products are designed for use with conven onal boilers which use water as a hea ng medium in a sealed or open expansion circuit. The heat exchangers are designed to handle high flow rates on the primary side to ensure that the heat transfer will be efficient while at the same me avoiding excessively low return water temperatures. Calorifiers with biomass boilers: The selec on of a calorifier while opera ng in conjunc on with a biomass boiler must take account of fact that excessively low return water temperatures could reduce the lifespan of the boiler. In addi on, a calorifier with a larger accumula on volume than normal will be more suitable as it will act as a buffer which will be beneficial to the biomass boiler. Calorifiers with condensing boilers: Condensing boilers are highly efficient and ecologically friendly. They operate at op mum performance when the flow water temperature is limited which results in the return water temperature being as low as possible. This will ensure that the latent heat is extracted out of the combus on products which will maximise the efficiency of the system. Calorifiers with solar systems: The heat exchange coil surface area is a cri cal issue when interfacing solar thermal systems with calorifiers due to limited primary flow rates and temperatures. The calorifier must also be capable of ac ng as a buffer to harness the solar energy throughout daylight hours. Calorifiers opera ng with more than one energy source The demand to heat a calorifier using more than one energy source, while at the same me keeping the various circuits separate, has become much more common in recent mes with the advent of renewable technologies which usually need to be backed-up with conven onal boilers. In these cases, calorifiers with a number of heat exchangers are used with the design ensuring that excellent thermal stra fica on will be achieved with minimal interference between the various heat sources. Calorifiers with heat pumps: Calorifiers opera ng in conjunc on with air-to-water or water-to-water heat pumps must have extremely oversized heat exchange surface areas to ensure that heat exchange will take place even when there is a limited difference in temperature between the primary circuit and secondary stored water. This will maximise the COP (coefficiency of performance) of the heat pump. Calorifiers opera ng with renewable energies D.H.W. produc on system connected to renewable energies, exploi ng natural resources coming from air, water and ground. Calorifiers with steam boilers: The use of saturated steam as a hea ng medium to produce domes c hot water, although li le used in the housing sector, is a solu on which is s ll employed in industrial environments where the steam is already in use for the manufacturing process. Technically speaking, steam calorifiers are charactorised by rela vely small heat exchangers, as on one hand the steam gives high heat exchange coefficients and on the other hand the exchangers usually operate with considerable differences in temperature between the primary and secondary circuits. The use of steam demands a more stringent safety regeime than the use of low pressure hot water systems as steam boilers, depending on their capacity and design pressures, are classified as higher risk and therefore must comply with the European Pressure Equipment Direc ve. Calorifiers opera ng with electrical power Cordivari products designed for working with electricity can be connected to A/C power supply. Combined with a renewable energy power supply system (fotovoltaic, wind energy, and so on), it allows to have an environmental friendly system. Domes c Hot Water produc on (D.H.W.) GUIDE WHEN CHOOSING STORAGE TANKS A storage tank is a well insulated tank that is inserted in hea ng systems powered by a biomass generator. It has the dual func on of allowing the generator to operate in a regular manner, restric ng the number of stoppages, and of crea ng a thermal stabiliser for the hea ng system, thus improving working comfort considerably. Cordivari offers a wide range of storage tanks, which include both standard versions and a number of combined versions to be used as a single appliance, ac ng both as a storage tank and to produce domes c hot water. Central hea ng systems with one or more boilers which are plumbed together and do not generate domes c hot water. Central hea ng systems with one or more boilers which are plumbed together in conjunc on with solar power which is connected to either one or two coil type heat exchangers. Domes c hot water is not generated in these tanks. Hea ng systems with one or more sources hydraulically divided, with the exploita on of the solar power and without DHW produc on. These are hea ng systems powered by a biomass generator or more generators that are hydraulically divided. The prepara on of the DHW is done without involving the hea ng hot water storage tank Combined central hea ng system and domes c hot water produc on with one or more boilers which are plumbed together.

9 PRODUCT NEWS 216 RANGE OF CALORIFIERS FOR HEAT PUMPS Installa ons with heat pumps represent one of the most developed segments in single or mul use systems. Cordivari extends the range of calorifiers for heat pumps. In this edi on of the catalogue they have an en re sec on dedicated, which is enriched with more models and each one is specialized for its own applica on. Cordivari offers calorifiers that can sa sfy every possible applica on concerning accumula ons for heat pumps, from buffers to mul -heat energy buffers used both for DHW produc on and for hea ng, and also tanks used only for DHW produc on. Made to be combined with heat pumps, high performance tanks can op mize the working process and performances thanks to systems and exchange surfaces specific for those applica ons. Tanks for heat pump range includes tanks from the series Bolly XL and Bolly PDC, and also mul -heat energy buffers from the series Eco- Combi PDC and Puffermas PDC. NEW BOLLY PDC RANGE New Bolly PDC tanks represent the most advanced of tanks for heat pumps evolu on, with a higher level of comfort and performances. Cordivari presents the new DHW prepara on and storage tanks range, expressly designed to use heat pumps as primary energy source. They work through a group of heat exchange, properly dimensioned in order to guarantee several benefits and minimize the hea ng me. Its main feature is a higher efficiency and a constant exchanged power during the prehea ng phase rather than tradi onal tanks, where the exchanged power decreases as the storage temperature increases. Many performance benefits derive from it, such as an important decrease of the star ng me of 25% than a tradi onal tank. This advantage is even bigger in combined systems with heat pump (for DHW and hea ng), where a higher level of comfort is produced by reducing the me to prepare the domes c water in order to dedicate more me to heat the environment. Compared to a tradi onal tank, the exchange system of the new Bolly PDC improves the working condi ons of the generator. Such result is due to the constant exchanged power that reduces the turning on and off cycles, it produces a higher overall performance and extends the heat pump lifecycle. The Bolly PDC range is available as mul -heat models (employing many energy sources) to integrate the solar thermal system or a tradi onal/condensing tank by using big exchangers. De Df (15) H13 (14) PRS MODULE FOR IMMEDIATE DHW PREPARATION PRS modules extend the range of immediate DHW produc on system to afford a higher flow rate or to cope with systems for many users. The new PRS modules are made for immediate prepara on (without storage) or semi-immediate (combined with a DHW accumulator) to be installed in medium or big systems. They guarantee high performances for con nuous DHW produc on with high flow rates. PRS modules work separately from the primary system energy circuit, so to be used with different heat generators (tradi onal, condensing, biomass, district hea ng, etc). Thanks to an advanced electronic control unit they are able to automa cally control several system models, punctually managing the an -legionellosis cycles, recording data and their results. PRS modules are equipped with a plate heat exchanger, high efficiency primary circula on pump (single or double to guarantee the supply even in case of breakdowns), primary mixing valve to avoid calcareous deposits, electronic panel for PLC management and control, besides a temperature feeler system. ErP 217 READY TANK RANGE From September, 26th 217, the Energy Related Products 29/125/CE ErP direc ve will introduce strict laws concerning water storage, both for DHW and hea ng, in order to face an increasing demand of more efficient products and higher heat performances.

The main advantages of having an external exchanger are higher efficiency and constant exchanged power during the pre-hea ng phase.

215 OPEN EXPANSION VESSELS S / G / P Opened Expansion tanks are used as safety accessories in the hea ng systems where, due to legal reason it is vorbidden to install closed expansion tanks systems. In Italy, for the water fireplaces, they are s ll one of the most simple and economic solu on. Expansion tank is composed by a cover unit where all the security piping of outlet pipe for too full, supplying and systems charge, should arrive. Its rule is to merge the water in excess due caused by temperature increase. Expansion Tank should be placed on the higher point reached by the water and should have an expanding volume not less the expansion volume developed by all the water contained into the system, whose value should be declared in the project. Expansion volume need it in the system is calculated by the following formula: Ve = C x e Where C is the water contained into the system and e is equal to the difference between the expansion factor of the water at the minimum conceivable temperature with sleeping system and the expansion factor of the water at boiling temperature of atmospheric pressure. Considering the first water temperature equal to 1 C and the boiling one at 1 C e =.431 If need you can connect more than one tanks all together.

261 THERMAL STRATIFICATION Thermal stra fica on is a physical process in which an hot fluid naturally tends to posi on itself higher than the cold one. The fluid (water) is always moving, and tends to remix, therefore the natural process of stra fica on must be supported to maintain an increasing temperature gradient from bo om to upper part and avoid the mixing of liquid at different temperatures. To allow stra fica on into the tanks means to create a remarkable difference in temperature storaging volume from upper to lower part. With important posi ve effects in terms of efficiency. A proper stra ficated storaging means to have quan es of hot water available in short me. Example of stra fica on: Heat received during the day is accumulated in the higher part of the tank, reaching a suitable temperature for end user, while in the lower part temperature remains cold and even when solar collectors have a temperature below the one needed (a ernoonevening), the heat exchanger con nues and tanks is storaging further energy. 75 C 7 C 65 C 6 C 55 C 5 C 45 C 4 C 35 C 3 C 25 C 2 C Hea ng delivery Standard Thermal stra fica on Efficient Thermal stra fica on 75 C 3 C THE TECHNICAL SOLUTIONS FOR THE OPTIMIZATION OF THERMAL STRATIFICATION For a con nuous improvement of efficiency and energy savings, Cordivari has developed innova ve technical solu ons for the op miza on of thermal stra fica on LABYRINTH SPREADER CORDIVARI PATENT Performances are op mized thanks to the Labyrinth Spreader (Cordivari Patent). Its spread shape allows a perfect stra fica on of the water that returns back from the plate exchange to the tank. Hea ng installa on efficiency is guaranteed. EASY STRATIFICATION BUFFERS CORDIVARI PATENT Sequence of thermographic images that show how Labyrinth Spreader works. The hea ng return stra fica on system (Cordivari patent), avoid any turbolences, that would affect the thermal stra fica on inside the buffer tank. Thanks to this op mized solu on, efficiency and energy savings are con nuosly improved. Stra fica on plate Hea ng return stra ficator system NEW BUFFER TANKS CTS Sequence of thermographic images that show how a system works with the easy stra fica on Buffer. The new range of Buffer Tanks CTS are Cordivari s last innova ve storage tanks designed for Solar Thermal Systems. The exclusive Stra fica on device CTS allows to have a prompt delivery of energy suitable for the produc on of hot water. The energy absorbed from the Solar Collectors is efficiently stra fied in the upper part of the tank through the CTS stra fica on device and separa on plate already assembled in Buffer CTS. The thermal stra fica on inside the Buffer tanks will be then improved naturally, without any external valves thanks to the mixed combina on of: 1. Labyrinth Spreader that allows a perfect stra fica on of the water that returns back from user thanks to its spread shape avoiding mixes of temperatures of storaged water 2. Upper thermal loading systems that concentrates in the upper part of the tank hot water produced by the lower solar fixed coil in short me and high temperature. 3. Lower fixed Heat Exchanger designed for an op mal rela on between space and efficiency. T S 259
