Heat Pumps The strengths The features that make this system worthwhile are multiple, but the most obvious advantage is that it is an intrinsically efficient system. It has direct repercussions on the amortisation of the installation cost and on the consumer s utility bills too. Moreover, using a heat pump enables the exploitation of portions of energy which would otherwise be wasted (such as in installations in boiler rooms). astly, this system also provides an easy and convenient integration with other renewable energy sources (solar panels, wood-fired boilers, etc.). Heat pumps are ideally installed in cellars or damp rooms because the humidity in the air is removed during (dehumidifying effect). The Systems The heart of the System is an indirect cylinder with a built-in heat pump that enables the simultaneous or selective use of up to four different energy sources: 1) thermal energy; 2) electricity; 3) solar power; 4) environmental energy. The heat pump is designed to transfer heat from a body at a lower temperature to another body at a higher temperature. This process is the opposite of what happens in nature, and is due to the fact that electricity is supplied to the appliance that heat pumps. The principle of the heat pump is a thermodynamic cycle opposite to refrigeration. The efficiency of a heat pump is represented by its performance coefficient OP, which is the ratio of the heat output yielded to the electrical power utilised. Safety The products are insulated using polyurethane foam which has been certified with a fire resistance class 2 according to IN 4102 (self-extinguishing). 4

The STRNTHS of the product range in detail: Operating principle The heat pump comprises a closed circuit made up of a compressor, a condenser, a lamination valve and an evaporator through which the heat transfer fluid flows. The thermodynamic cycle the fluid experiences consists in an adiabatic compression, a condensation phase, an expansion phase and also evaporation. uring compression, the pressure and temperature of the fluid rise, during the second stage the fluid flows through a heat exchanger (condenser) where it comes into contact with domestic water, to which it yields heat. uring the third stage, the fluid flows through an expansion valve (lamination process) and its pressure and temperature consequently drop. uring the last stage, referred to as evaporation, the fluid switches from its liquid state to gas: the coolant is at very low temperatures, which enable it to absorb heat from the external heat transfer fluid. So during the of the heat pump, the following occurs: electricity is consumed in the compressor, heat is absorbed from the external environment (evaporator) and heat is yielded in the condenser to the liquid that needs to be heated. The advantage of a heat pump lies in the fact that more energy is supplied in the form of heat than the electricity required for its.

The STRNTHS of the product range in detail: This range of indirect cylinders performs indirect heating via one or two fixed coils with extensive heat exchange surfaces. They provide an easy and abundant supply of hot water for all uses. They can be connected to both independent and central heating systems, or to remote heating systems or they can be used in forced flow solar-powered systems, providing high heat exchange efficiency levels. The range of capacities covered by this product line is from 80 to 2000 litres with power ratings of between 20 kw and over 250 kw of heat output. The models available include undermount appliances to be fitted below the boiler, which are ideally combined with any wall-hung boiler for the production of large quantities of hot water in a limited amount of space, along with the multi-purpose free standing versions which comprise single and double coil indirect cylinders, designed to integrate several types of energy available, from methane gas via a gas boiler, to electrical installations using the integration kit available, and even solar energy systems with the forced flow solarpowered systems. The line of indirect cylinders is completed with the multiposition which has a distinguishing trait: its versatility, which makes both vertical and horizontal as well as floor-standing installations possible. Thermal Insulation Insulation layer made of very thick high-density polyurethane (PU) foam that guarantees excellent insulation. ess heat loss means lower energy waste. Tank protection against wear Thanks to the flow-coating enamelling process at 850 for guaranteed quality internal protection. Safety The products are insulated using polyurethane foam which has been certified with a fire resistance class 2 according to IN 4102 (self-extinguishing). Magnesium anode eatured in all the models in the range, this anode makes for effective electrochemical tank protection. nvironmentally friendly We strive to optimise our industrial activity while respecting the environment. To minimise the environmental impact of its products, it has abolished the use of chlorofluorocarbon (-H) in the insulation layer and makes continuous efforts to use recyclable components. 19

The STRNTHS of the product range in detail: The range of buffer cilinders is formed by heating water storages with the opportunity to combine a fixed coil exchanger, too. They allow storing heating water generated by discontinuous heating systems; therefore, they allow a considerable recovery and/or exploitation of thermal energy that would be unused or even wasted. rom this point of view, they well integrate into energy saving systems, and become the thermal source of the energy system within heating and domestic hot water generation systems. Owing to their peculiarity, they are usually connected to systems that generate heat in a discontinuous way, such as for example wood-fired boilers, solid-fuel stacks or stoves, or rather installed in low water systems to limit the interventions of the burners. s for the version with fixed exchanger, besides what is said above, it is used for maximum exploitation of thermal solar systems or with heat pump. The capacity field covered by this range is included between 200 and 2,000 litres. Product lines cover the standard, with front hatchway, solar with fixed exchanger and front hatchway up to solar with the production of domestic hot water. ll products are equipped with fittings for electric integrations by means of specific kits from 3.0 kw to 12.0 kw, while the products having the hatchway can install further electric kits from 2.0 to 10.0 kw, or kits with tinned copper spiroid exchangers. Thermal Insulation Insulation layer made of very thick high-density polyurethane (PU) foam that guarantees excellent insulation. ess heat loss means lower energy waste. Safety The products are insulated using polyurethane foam which has been certified with a fire resistance class 2 according to IN 4102 (self-extinguishing). nvironmentally friendly We strive to optimise our industrial activity while respecting the environment. To minimise the environmental impact of its products, it has abolished the use of chlorofluorocarbon (-H) in the insulation layer and makes continuous efforts to use recyclable components. 41

Wood ired Water Heaters WOO IR WTR HTRS Wood is a renewable source of energy that may be regenerated continuously. With a rational and sustainable use of forest areas, an immense mass of energy may be supplied which derives indirectly from the sun. We have come up with an appliance that fully exploits the natural energy released by wood, using a water jacket collar on the flue of a fire heater, it is a traditional way of heating water and is extremely effective. Using a wood fired water heaters, alone or combined, means having heat available at a low cost and in an environmentally friendly way, it is an easy and inexpensive possibility to make a noticeable dent in your utility bill, available in both for only wood SRIS, either in version combi wood-electric SRIS or, SRIS /T the only model where solar hot water system and wood fired water heaters can be connected together to provide substantial savings on your annual hot water running costs. The STRNTHS of the product range in detail: Tank protection against wear Thanks to the flow-coating enamelling process at 850 for guaranteed quality. Magnesium anode eatured in all the models in the range, this anode makes for effective electrochemical tank protection. nvironmentally friendly We strive to optimise its industrial activity while respecting the environment. To minimise the environmental impact of its products, it has abolished the use of chlorofluorocarbons (-H) in the insulation layer and makes continuous efforts to use recyclable components. 64
