General characteristics
Next Evo EU
The sealed chamber instantaneous water heater
Ariston launches Next Evo , the new instantaneous gas water heater for the production of domestic hot water. Characterized by an exclusive design, reduced dimensions and new functions, Next Evo is even more efficient and easy to use. The innovative electronic control of Next Evo allows you to adjust, via an intuitive LCD display, the ideal temperature for the user and to keep it constant even when the required water flow varies, thanks to the two NTC probes which measure the temperature of the both incoming and outgoing water. The central position of the smoke outlet and the extremely reduced depth (only 17.5 cm) make it extremely flexible and easy to install.
Maximum energy saving is ensured by the possible integration of Next Evo with natural and forced circulation thermal solar systems: the solar kit with thermostatic valve has been designed precisely to facilitate its implementation. A new, innovative way of conceiving solar integration: versatile, practical and easy to install
Characteristics:
- Ultra compact: only 17.5 cm deep
- Thermostatic: modulating temperature control via NTC probes allowing high standards in terms of energy saving and comfort
- Flame ionisation electronic ignition with gas savings of up to 25% compared to older generations
- Operation with water pressure 0.1 bar
- Operation even with minimum water flow rates > 2 l/min
- Can be integrated with solar thermal systems
- Presence of the smoke pressure switch
- Presence of the water flow switch
- IPX4D electrical protection
Ecodesign Directive
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
