This new unit features innovative e-Matic technology, a wide modulation range, and is designed to be exceptionally installation- and service-friendly.
The proven quality of the Calenta Ace has been further optimized with e-Matic technology. This means the unit has a self-adjusting gas-air system, ensuring optimal combustion at all times.
The new Calenta Ace-Matic offers a modulation range of 1:10, reducing the number of switching cycles. This makes the unit more environmentally friendly and energy-efficient, making it the perfect combination with a hybrid heat pump.
The Calenta Ace-Matic stands out for its highly installation- and maintenance-friendly design. It is robustly built, with intelligently integrated and easily accessible boiler components. The unit also features internal lighting. The interchangeable parts and compatible accessories with other Ace models make installation sustainable, efficient, and convenient. Thanks to advanced control options, the system can be easily expanded and connected to the internet via the Plug & Play connector.
