This new device features e-Matic technology, a wide modulation range, and is particularly installation- and service-friendly.
The quality of the Calenta Ace is now enhanced with e-Matic technology. This means that the device has a self-adjusting gas/air system, ensuring optimal adjustment/combustion at all times.
The new Calenta Ace-Matic offers a modulation range of 1:10, which results in fewer switch cycles. This makes the device more environmentally friendly and energy-efficient and is the perfect combination with a hybrid heat pump.
The Calenta Ace-Matic offers a highly installation- and service-friendly design. The device is robustly built, all boiler components are intelligently integrated and easily accessible. It is also equipped with internal lighting. The interchangeable parts and compatible accessories with other Ace devices make installation sustainable, efficient, and user-friendly. Thanks to the advanced control features, the system can be easily expanded and connected to the internet via the Plug & Play connector.
✔ Easy commissioning
✔ Always optimal combustion
✔ Quieter and cleaner control behavior
✔ Further standardization/simplification of the product portfolio
✔ With Ace platform: know one, know them all
✔ Highly installation, maintenance, and service-friendly
✔ Significantly more hot water than required by Gaskeur CW
⚠ Attention: This boiler is supplied in a concentric version.
