General Features
Next Evo EU
The sealed chamber instantaneous water heater
Ariston launches Next Evo, the new instantaneous gas water heater for domestic hot water. Featuring an exclusive design, compact size, and new features, Next Evo is even more efficient and easier to use. The innovative electronic control system of Next Evo allows you to adjust the ideal temperature for the user via an intuitive LCD display and maintain it constant even when the water flow rate varies, thanks to two NTC probes that measure both incoming and outgoing water temperatures. The centrally positioned flue and its extremely shallow depth (only 17.5 cm) make it extremely flexible and easy to install.
Maximum energy savings are ensured by the possible integration of Next Evo with natural and forced circulation solar thermal systems: the solar kit with thermostatic valve was designed specifically to facilitate this implementation. A new, innovative approach to solar integration: versatile, practical, and easy to install.
