Addition of e-Matic technology
The quality of the Calenta Ace is now enhanced with e-Matic technology. This means that the unit has an auto-adjusting gas/air system, ensuring optimal setting and combustion at all times.
Wide modulation range
The new Calenta Ace-Matic has a modulation range of 1:10. This results in fewer switchings, making the unit more environmentally friendly and energy-efficient. Therefore, this unit is also the perfect match for a hybrid heat pump.
Extremely installation- and service-friendly
With the Calenta Ace-Matic, you get a highly installation- and service-friendly device. It is robustly built, all boiler components are cleverly integrated and easily accessible. The unit is equipped with internal lighting. The interchangeable parts and accessories with other Ace devices are sustainable, efficient, and provide ease for the installer. The extensive control capabilities can be easily expanded and connected to the internet via the Plug & Play connector.
All advantages at a glance:
Note: This boiler is supplied in a parallel design.
