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.
Genus Premium Evo
The Genus Premium Evo wall-mounted boiler is the maximum expression of the Ariston range. Thanks to the condensing technology, by recovering the energy of the exhaust fumes, it generates an increase in the calorific value which makes it possible to eliminate waste (of energy) and to obtain higher thermal efficiency than conventional boilers. Genus Premium Evo offers even greater performance thanks to the innovative technology that allows it to self-regulate according to variations in the external and internal temperature of the room, allowing energy savings of up to 35% compared to an older generation boiler. It is available in the heating and domestic hot water production version in 3 powers: 24-30-35 kW (sealed chamber).
Characteristics:
Convenience function:
The Comfort function speeds up the delivery of domestic hot water, reducing waiting times down to just 5”. This service can be customized by choosing between two modes of use:
- COMFORT PLUS (hot water immediately ready every time the tap is opened in just 5 seconds)
- COMFORT (hot water ready for 30 minutes after the last withdrawal so as not to give up savings)
car function:
It is truly possible to combine maximum comfort with reduced consumption, thanks to the intelligent management logic of the new boilers and the new technology that governs them. By activating the AUTO function, the Ariston boiler chooses the best operating mode based on the environmental conditions, the connected external devices and the required performance. Impossible to compare this ability to interpret and respond to external stimuli with what has been achieved so far. AUTO does not fear comparisons
Acoustic comfort
Acoustic comfort is further guaranteed by the introduction of the new silencer. For the Clas Premium Evo thanks also to the high modulation ratio of 1:10, the continuously modulating pump and the presence of side sound-absorbing panels.
High efficiency circulator with continuous modulation:
It allows automatic adaptation of the power based on the temperature of the system, guaranteeing boiler performance and reducing electricity consumption.
- Optimization of thermal efficiency.
- Optimization of comfort with constant temperature.
- Maximum silence.
High efficiency
The condensing technology makes it possible to achieve high energy efficiency thanks to the increase in the calorific value generated by the reuse of the energy of the exhaust fumes, allowing for a higher thermal efficiency. The future of the planet and your comfort are the main objectives of Ariston condensing technology

Ecodesign directive: from 2015 only new condensing boilers
After very long negotiations , the Ecodesign regulation was approved which introduces a new energy labeling on the minimum efficiency standards for boilers. 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 ones on the market starting from 26 September 2015 . This means that starting from this date, anyone wishing to install a boiler in their own home will only have to install condensing models. 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
