The Dalesman Hot Water Boiler

A traditional three pass wetback shell hot water boiler

The Dalesman is a traditional three pass wetback shell hot water boiler, and is ideally suited to cope with the rigours and continual heavy workload demanded for commercial heating and industrial process applications.

The Dalesman high and medium temperature versions incorporate the unique X-ID boiler tube. With special helical internal ribs this tube increases heat transfer from tube to water space, making the Dalesman a most energy efficient hot water boiler.
