Atag Wall Mounted Boiler XL75W AT-B-WXL75

Balancing power with a plant room footprint is a constant challenge when designing a heating system for a large commercial space. The Atag Wall Mounted Boiler XL75W AT B WXL75 provides the perfect solution. As part of a new range of technologically advanced, high-efficiency boilers from ATAG Commercial, this wall-mounted heating unit delivers formidable power from a compact design, offering unmatched flexibility for modern installations.

A New Era in Commercial Heating Flexibility and Power

The Atag Wall Mounted Boiler XL75W AT B WXL75 is engineered for medium to large commercial properties where performance, efficiency, and ease of installation are paramount. It represents a significant leap forward, offering exceptional flexibility that can dramatically reduce installation times. Its clever design allows for it to be installed either in-line or back-to-back, giving installers the choice of a wall-mounted or a free-standing cascade arrangement. It is an ideal solution for plant rooms with limited vertical space, with a low installation height of just 1.8m (not including the flue). When fitted in a cascade formation, these boilers boast the smallest, most compact footprint in the industry in terms of width, making the wall-mounted heating unit the definitive choice for projects where every square inch of plant room space is precious.

The true strength of the XL75W lies in its incredible modular scalability. While a single unit provides a powerful 75kW output, it can be used in cascade arrangements of up to eight boilers. This is all managed seamlessly by a built-in controller and connected with an easy plug-and-play BUS communication cable, allowing for a massive combined output of 600kW. This modular approach is far superior to a single, oversized boiler, as it allows the system to modulate its output precisely to match the building's heating demand, ensuring peak efficiency and reducing energy waste. At its heart, the single-engine design features a robust stainless steel heat exchanger, guaranteeing high efficiency and longevity. It also includes an integral modulating ‘A’ rated pump that constantly sends feedback, and a 1:5 modulation range for precise energy management. To complete the premium package, it comes as standard with high-quality insulation that keeps heat loss to an absolute minimum while minimising noise emissions to industry-leading standards.

For seamless integration and control, the durable electronic components and control panel are strategically positioned at the top of the boiler. This guarantees maximum durability and gives engineers easy access to all boiler parameters for servicing. For ultimate connectivity in a modern smart building, optional gateways are available for BACnet, KNX, LonBus, and Modbus protocols, ensuring compatibility with almost any Building Management System. This advanced boiler comes with a comprehensive 7-year warranty.
