The new Gas 320 Ace builds on the success of its predecessor, the Gas 310 Eco Pro, combining cleverly engineered new features with class-leading compact dimensions to deliver the enhanced flexibility, connectivity and control that modern heating solutions demand.

With a high temperature differential (∆T) of 10°C to 40°C and wide operating range of 20°C to 80°C/90°C, the new Gas 320 Ace is the perfect heat source for heat interface units, low temperature heating and hybrid installations as well as for retrofit applications.

Its unique low water content heat exchanger allows for low to zero flow condition operation and monitoring, enabling it to respond rapidly to increasing or decreasing changes in load and reduce running costs.

Boiler control has been improved with the Ace control platform delivering superior control capability for optimal lifetime performance. An intuitive controller ensures rapid access to an extended range of parameters, making installation and maintenance even easier and maximising boiler efficiency.

Connectivity has also been optimised with a new Modbus gateway option enabling remote connection to a Building Management System and optional Bluetooth functionality for enhanced connectivity.

The new Gas 320 Ace comes inclusive of commissioning and is fully backed by an industry-leading comprehensive 7-year warranty, and a 24/7 round-the-clock technical support helpline.

Like the Gas 310 range, the new Gas 320 is designed to provide optimum design flexibility for designers and installers. Lightweight and narrow enough to fit through a standard doorway or lift, the multiple configuration options make installation easier while improving access for servicing and maintenance.
