NEXT-R Gas Unit Heater

The Robur NEXT-R is a modulating wall-mounted gas unit heater with a premix burner, designed for efficient heating of industrial and commercial spaces of any size. Available in seven output sizes (R15 to R80, covering 13 to 84kW) and three mounting configurations: axial fan for horizontal blowing, vertical downflow for ceiling mounting, and centrifugal fan for ducted applications. Thermal efficiency reaches up to 97.4% at part load, delivering measurable gas savings of 20 to 25% compared to conventional non-condensing heaters. The Robur Comfort Zone System produces low heat stratification (0.3°C per metre of height), keeping warmth at floor level where it's needed. 25% lighter than comparable models, the NEXT-R is designed for fast, simple installation: single wall penetration for the balanced flue, gas and power connections only, no central plant room or pipework required. The structure is built for quick access and easy maintenance. Each unit connects to the Genius control system, managing up to 100 heaters across 30 independent zones with remote monitoring, fault reporting, and scheduling. Modbus interface available for BMS integration. Certified for hydrogen blends up to 20%. Type C (room sealed) combustion circuit with air drawn from outside. Low NOx and CO emissions via self-adapting air-to-gas ratio.
