This new appliance features e-Matic technology, a wide modulation range, and is exceptionally installation- and service-friendly.
The quality of the Calenta Ace is now enhanced with e-Matic technology. This means the appliance is equipped with a self-regulating gas/air system, ensuring optimal adjustment/combustion at all times.
The new Calenta Ace-Matic has a modulation range of 1:10, which results in fewer switching cycles, making the appliance more environmentally friendly and energy-efficient. This also makes it the perfect combination with a hybrid heat pump.
The Calenta Ace-Matic provides a highly installation- and service-friendly appliance. It is robustly designed, with all boiler components smartly integrated and easily accessible. The appliance features internal lighting. Interchangeable parts and accessories with other Ace devices make it sustainable, efficient, and user-friendly for the installer. The extensive control options are easily expandable and can be connected to the internet via the Plug & Play connector.
