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.

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.

Continuous improvement leads today to the evolution of the Family condensing range, starting from its primary element: the exchanger. The new Family exchanger is made of stainless steel, with a smooth tube with a large section to guarantee the best efficiency and cleanliness over time. Access remains from the front, to facilitate maintenance operations. Riello has also optimized the DHW exchanger by adopting the most advanced fluid-thermodynamic analysis and simulation techniques to obtain the best performance and maximum comfort for the user in terms of waiting times and temperature stability during sampling, compared to a boiler traditional MAXIMUM POSSIBLE LOAD PROFILE IN RELATION TO THE TYPE AND POWER OF THE GENERATOR, UP TO XXL IN THE CASE OF 35 KW FAMILY. SANITARY ENERGY EFFICIENCY CLASS A, THE MAXIMUM VALUE CURRENTLY PROVIDED BY EU REGULATION 811/2013 FOR COMBINED GENERATORS (TRADITIONAL B OILER CLASS B). REDUCTION OF GAS CONSUMPTION COMPARED WITH A TRA ADTIONAL BOILER BY APPROXIMATELY 10%, ACCORDING TO EN13203-2. ALMOST NULL WAITING TIME FOR HOT WATER (< 1 SECOND) WITH DOMESTIC HOT WATER PRE-HEATING FUNCTION ACTIVE (TRADITIONAL BOILER ABOUT 40 SECONDS). Emissions always under control The new Family is equipped with the intelligent ACC combustion control system, which guarantees that the process always takes place in an optimal manner in any condition, thanks to the modulating gas valve and the ionisation electrode. Thanks to the ACC, the Family is able to automatically adapt to the fuel (methane or LPG) without resorting to specific codes or accessory conversion kits. Family also reacts to the variation of the fuel title and to the pressure drops on the flue gas side. The ACC system detects the excess air value and intervenes by modulating the air/gas mixture to always keep it within the optimal parameters. The ACC system also simplifies installation. In the ignition phase, it does not require calibration and it is sufficient to select the type of combustible gas used by the boiler via the interface, if different from the default one (methane). Since the system keeps the value of the CO2 produced constant, even the smoke control during the ignition phase is no longer necessary for the correct functioning of the product. Controlling combustion also means guaranteeing constant emissions, which are always well below the limits set by the law. In fact, if the process takes place in an optimal manner, the gases produced will also have the best theoretical composition with respect to the other conditions. Control panel and functions Even clearer, more intuitive and easier to use, it integrates elegantly into the aesthetics of the machine. The large backlit display, the raised keys and the interface enriched with explanatory texts and icons help the user and the installer in navigation. Through the panel it is possible to view the operating status, carry out the programming and access the regulation of the boiler and system.
