The Beretta hybrid, distinguishing itself for its modular approach to the world of multi-energies, is therefore able to offer increasingly tailored comfort and to evolve over time, with the inclusion of new components that increase efficiency   Beretta is “ERP”. The concrete commitment towards an eco-sustainable future   The acronym ErP, acronym of "Energy related Products" (Products connected to the use of energy), identifies the Directive 2009/125/EC aimed at reducing the energy consumption of products through eco-compatible design. Starting from 26 September 2015 , the date of its effective entry into force in the European Union, it will mark an epochal turning point for heating products and the production of domestic hot water. On that date, other regulations simultaneously issued for the energy labeling of products will also become effective in addition to the corresponding Directive 2010/30/EU.  The regulation provides that all products intended for heating and for the production of domestic hot water with a nominal thermal power lower than or equal to 70 kW can only be placed on the market with an energy label that highlights the efficiency class * . Different energy efficiency labels have been provided based on the different types of appliances/technologies, but all have the same graduated color scale that identifies the various levels of efficiency at a glance. The purpose of the labels is to give the consumer the possibility to easily identify the level of efficiency of a product and to be able to make a homogeneous comparison between products that use different technologies. For products whose transformation efficiency is influenced by external conditions, such as heat pumps, the efficiency data is reported by climatic bands.   In addition to the product labels, the European regulation has provided for the creation of a system label in case systems are created with different appliances, components and related controls. This second type of labeling, thanks to the virtuous synergy between the different elements, will make it possible to create systems capable of reaching levels of efficiency even higher than those of the individual appliances. Also starting from the same date, new seasonal efficiency limits will be triggered for products intended for heating and combined. These for products with nominal thermal power equal to or less than 400kW, will prevent less efficient products from being placed on the market. The obligation to comply with minimum heat loss limits will also apply to DHW tanks. For primary water tanks, these will be subject to compliance with an energy classification based on heat dispersion. For sanitary accumulations, up to 500 liters there will be a labeling obligation, from 500 to 2000 liters will be bound to compliance with the energy classification. For heat pumps for heating and mixed appliances, in addition to the seasonal efficiency limits, there will be specific noise emission limits for power sizes. Even water heaters, whether gas, heat pump or solar, in order to be placed on the market, in addition to energy labelling, will have to comply with a series of requirements in terms of efficiency.   Warranty All products for sale on our site are new and packed.

The recovered heat is transferred to the heating system, making it possible to achieve a yield of 106% with 92% of the traditional boiler and 84/85% of an oldÿÿtraditional generator.ÿThe installation obligation concerns manufacturers of boilers which will no longer be able to place on the market non-condensing starting from 26 September 2015. This means that starting from this date, anyone who wants to install a boiler in their own home will have to install only condensing models. Only one particular type of non-condensing boiler will continue to be produced which is technically called open room? to be installedÿ when it is not possible to replace an old boiler with a condensing boilerÿdue to problems related to the collective flueÿof some multi-family buildings. Products for heating water and the environment represent around 30% of the world's energy consumption in Europe.ÿ Designing eco-friendly products and promoting high performance technologies to end users in 2020 will lead to: An annual energy saving equivalent to 56 million tons of oil, quantifiable to the savings obtained if the water and environmental heating systems of two large nations like Italy were deactivated. As of 26 September 2015, the ErP regulation and ÿenergy labelingÿwill be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and hot water storage tanks) u. How to read energy labels There are different labels, based on the type and function of the product (only room water heating of both, and in this case the label must bear both classifications). In addition to the energy class, the label provides other information that could be useful for understanding which product has the least environmental impact (for example power and consumption in different climatic zones, noise levels, etc.). It is possible to increase the energy efficiency of hot water production and space heating by connecting several products and accessories in one system. In this case it is necessary to prepare a system label in addition to that relating to the single product Warranty All products for sale on our site are new and packed.

In particular, an energy classification from A+ to G is envisaged for space heating appliances and from A to G for domestic hot water production appliances. Hence the obligation to install only condensing boilers, heat generators capable of recovering a large part of the latent heat contained in the fumes which, otherwise, would be dispersed in the chimney as occurs in traditional boilers. The recovered heat is transferred to the heating system, allowing to reach an efficiency of 106% against 92% of the traditional boiler and 84/85% of an old traditional generator. The installation obligation concerns boiler manufacturers who will no longer be able to place non-condensing boilers on the market starting from 26 September 2015. This means that starting from this date, anyone who wants to install a boiler in their own home will only have to install models condensing. Only a particular type of non-condensing boiler will continue to be produced which is technically called "open chamber" to be installed when it is not possible to replace an old boiler with a condensing boiler due to problems related to the collective flue of some multi-family buildings . What is Energy Labeling? Products for heating water and the environment represent around 30% of internal energy consumption in Europe. Designing eco-friendly products and promoting high performance technologies to end users in 2020 will lead to: An annual energy saving equivalent to 56 million tons of oil, quantifiable to the savings obtained if the water and environmental heating systems of two large nations such as Italy were deactivated. As of 26 September 2015, ErP regulation and energy labeling will be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and water storage tanks hot)¹. How to read energy labels There are different labels, based on the type and functions of the product (water heating or space heating only or both, and in this case the label must show both classifications). In addition to the energy class, the label provides other information that could be useful for understanding which product has the least environmental impact (for example power and consumption in different climatic zones, noise, etc.). It is possible to increase the energy efficiency of hot water production and space heating by connecting several products and accessories in one system. In this case it is necessary to prepare a system label in addition to that relating to the single product Product Guarantee: All products for sale on our site are new and packed.

ARISTON CLAS B PREMIUM EVO 24 EU CONDENSING BOILER COMPLETE WITH METHANE-ErP FUME KIT Technical features Product code: 3300608 Energy label specifications according to the European ErP directive Class A heating energy efficiency Sanitary energy efficiency profile XL Class A Characteristics of heating/DHW operation: For heating and domestic hot water production Forced draft sealed chamber Nominal heat input in heating max/min kW 22/5.5 Nominal heat input in DHW max/min kW 26/5.5 Max/min heating thermal power (80°C-60°C) kW 21.5/5.2 Efficiency at nominal heat input (60/80°C) % 97.8 Efficiency at nominal heat input (30/50°C) % 106.2 Efficiency at 30% at 30°C % 109 Performance stars (dir. 92/42/EEC) ★★★★ Min/max heating temperature (high temperature range) °C 35/ 82 Min/max heating temperature (low temperature range)°C 20/ 45 Specific flow rate in DHW (10 min. with ∆T=30°C) litres/min 18.8 Quantity of hot water ∆T=25°C litres/min 14.6 Quantity of hot water ∆T=35°C litres/min 10.4 Comfort performance stars (EN13203) ★★★ Supply voltage/frequency V/Hz 230 / 50 Total absorbed electric power W 110 Degrees of protection of the electrical system IP X5D Dimensions (H x W x D) mm 900/600/460 METHANE power supply General characteristics Ariston condensing boilers 1 condensing boiler = -737kg CO2/year 1 condensing boiler = 60 more trees Together with the heat, a traditional boiler also produces water in the vapor state, usually evacuated through the exhaust fumes. Normal boilers, since they do not treat these fumes before releasing them into the environment, therefore have a thermal efficiency based exclusively on the lower calorific value. The water vapor is not recovered in any way, thus dispersing part of the energy produced during combustion. Condensation is the physical process which, inside the boiler, transforms the water again from the vapor state to the liquid one. CLAS PREMIUM EVO, exploits the phenomenon of condensation in its favor by reusing the energy of the exhaust fumes and increases the useful calorific value, thus reaching the thermal efficiency of over 107%. Furthermore, during this process, most of the harmful combustion products for the environment and health, they are eliminated together with the condensed water. Consistent convenience The new products, using condensing technology, eliminate waste with great energy and economic savings. Thanks to the savings in the bill, less than three years are enough to amortize the higher cost of a condensing boiler. After that, the lower consumption translates into a real gain. Imagine what a reduced bill of up to 35% every year, for many years, means for your economies... Zero waste, only benefits Today Ariston combines energy savings with tax savings, offering a great opportunity to those who have chosen to replace the old boiler with a condensing one. In fact, the Finance law provides for specific tax incentives in favor of taxpayers. EVO : energy saving becomes reality, for everyone's well-being Among the measures aimed at reducing the energy consumption of buildings (European Directive 2010/30/EC), the Italian legislation has introduced "The obligation of the Energy Certificate of the building" in the purchase and sale of new and existing buildings. They have also been extended until throughout June 2013, bringing them to a value of 50%, the "tax credit deductions relating to building renovations and energy efficiency interventions". For the purpose of achieving the national objectives envisaged on the coverage of consumption through renewable energy sources (European Directive 2009/28/EC) it also requires and promotes "the use of heating systems operating on renewable energy". With the EVO range, Ariston satisfies all the indications envisaged for having "low energy consumption buildings", guaranteeing optimal integration with systems using renewable energy. Class B Premium Evo Clas B Premium EVO, with integrated double 40-litre stratification boiler, has been designed for intelligent management of domestic water. The new Clas B Premium EVO boilers, equipped with the new ABC System storage system, rationalize energy consumption and ensure cost savings on bills. The new system, a great technological intuition by Ariston, makes it possible to immediately obtain large quantities of hot water without waiting for the water in the boilers to heat up completely, thus avoiding useless waste of energy. Clas B Premium EVO is available in the heating and domestic hot water production version in 2 powers: 24 and 35 kW (sealed chamber).
