Commercial & Industrial Hot Water Boilers
O’Brien commercial and industrial hot water boilers deliver efficient, reliable heating for buildings and process sites across Australia. Our three-pass reverse-flame, wet-back hot water design runs on gas or liquid fuels, with high water volume and an anti-scale, anti-condensate construction for long, dependable service. Condensing Ecodense models recover flue-gas heat to push efficiency higher and cut running costs.
High efficiency
Condensing Ecodense models recover latent heat from the flue gas, reaching efficiency levels up to 98% and lowering fuel costs.
Durable construction
Laser-cut, electrically welded S235JR steel body with anti-scale, anti-condensate design engineered for decades of reliable service.
High water volume
Large water content with high-temperature spiral turbulators improves heat retention and transfer for stable, efficient hot water.
Low maintenance
Reversible-opening, ceramic-fibre insulated front door and accessible tubes make inspection and cleaning fast, minimising downtime.
