Addition of e-Matic Technology
The quality of the Calenta Ace is now enhanced with e-Matic technology. This means the appliance is equipped with a self-adjusting gas/air system, ensuring optimal adjustment/combustion at all times.
Wide Modulation Range
With the new Calenta Ace-Matic, the appliance has a modulation range of 1:10. This results in fewer cycles, making the appliance more environmentally friendly and energy-efficient. As a result, it is also the perfect combination with a hybrid heat pump.
Very Installation and Service Friendly
With the Calenta Ace-Matic, you get a highly installation- and service-friendly appliance. It is robustly built, with all boiler components cleverly integrated and easily accessible. The appliance is equipped with internal lighting. The interchangeable parts and accessories with other Ace appliances are sustainable, efficient, and provide convenience for the installer. The extensive control options are easy to expand and connect to the internet via the Plug & Play connector.
All advantages at a glance:
Note: This boiler is delivered in a parallel version.
