Brand: Robur

Quantity

Modulating wall-mounted condensing gas unit heater

Advantages

Up to 106% thermal efficiency with savings of up to 25% compared to alternative systems thanks to condensation.
Heat is quickly available in 30 minutes–even in the largest rooms.
It features the latest-generation electronics with advanced management functions as well as the possibility of centralised and remote management.
Greater comfort thanks to the heat output (from 100% to 30%) and modulation.
Reduced CO and NOx emissions thanks to an optimal air-to-gas ratio of the premix burner.
Also available with brushless fans to guarantee better comfort, noise reduction and reduced electricity consumption.
Safety and reliability with Type C certification. The combustion circuit is completely isolated from the installation environment and the combustion air is taken from outside, leaving the oxygen present in the rooms untouched.
Certified for operation with hydrogen mixtures up to 20%.
