Addition of e-Matic Technology
The quality of the Calenta Ace is now equipped with e-Matic technology. This means that the appliance has a self-adjusting gas/air system, ensuring always optimal settings/combustion.
Wide Modulation Range
The new Calenta Ace-Matic has a modulation range of 1:10. This results in fewer switching cycles, making the appliance more environmentally friendly and energy-efficient. As a result, this appliance 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, all boiler components are cleverly integrated and easily accessible. The appliance features internal lighting. The interchangeable parts and accessories with other Ace appliances are durable, efficient, and provide convenience for the installer. The extensive control options are easy to expand and can be connected to the internet via the Plug & Play connector.
