The intelligent Calenta Ace is ready for the (digital) future, thanks to the new appliance control system (eSmart Inside). The Calenta Ace boiler is equipped with brass hydraulic blocks. The heat exchanger used in the Calenta Ace is treated with a surface coating, meaning it does not need to be cleaned physically. The installation of this boiler is easy as the mounting bracket comes with an integrated spirit level.
The system can be optionally expanded with a (semi-)automatic filling unit, allowing the system to be automatically and intelligently refilled via the boiler's control panel, the eTwist, or through the convenient eTwist app.
This model is equipped with a concentric flue gas outlet.
