The intelligent Calenta Ace is ready for the (digital) future thanks to the new device control (eSmart Inside). The Calenta Ace boiler features brass hydro blocks. The heat exchanger used in the Calenta Ace is treated with a surface coating, eliminating the need for physical cleaning. The installation of this boiler is easy, as the mounting bracket has an integrated spirit level.
The system can be optionally expanded with a (semi)-automatic refill unit, which allows the system to be automatically and intelligently refilled through the boiler's control panel, the eTwist, or via the handy eTwist app.
