NEXT-G
G, as in Gas unit heater.
The original.
Modulating wall-mounted condensing gas unit heater.
The best value-for-money heating solution available thanks to condensation.



A product that has become synonymous with gas-powered unit heaters.
A completely modular solution capable of producing savings of up to 25% compared to conventional systems and efficiency of up to 107% (calculated in accordance with European regulation EN17082) thanks to condensation without losses in the heat distribution system.
Robur sets new standards with a gas unit heater that sets itself apart because of its design and technology and the wide range of management and control systems equipped to guarantee the best performance.
Next-G advantages
- Up to 107% 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%.

Robur gas unit heaters advantages
1. Immediate heat, simple as that.
Robur gas unit heaters reduce preheating times to a minimum and maintain the comfort temperature thanks to the low thermal inertia. Even the largest rooms are immediately warm in a short time because it works in the absence of carrier fluid, unlike water systems.
2. Modular. Just like your needs
Each gas unit heater is stand-alone and completely independent: heat where you want when you want. It’s ideal when considering modifications, relocations or extensions of the system and allows productive use of the interior areas thanks to the wall-mounted installation.

3. Ground effect: comfort and energy saving
Robur gas unit heaters heat rooms with a very low heat stratification due to the characteristic ground effect. The conformation of the heat exchangers and the special aluminium alloy divide the air flow into different layers with different temperatures, warmer at the bottom and cooler at the top. This eliminates heat loss in the higher areas of the room, which is good for comfort and saves energy.

4. Quick and easy installation
All you need is a single hole in the wall for the air intake/flue gas exhaust ducts and connection to the gas and power supply mains and the gas unit heater will be immediately operational.
