The Stackmaster is an internal device that is designed and factory installed to increase the operating efficiency of a boiler, cutting down on its operational costs over the lifetime of the boiler. The Hurst internal stack economizer acts as a waste heat recovery device, ensuring that this available heat does not go unused. Instead, the heat is recovered to essentially preheat the boiler’s makeup water.

Consider this option as a built in feedwater heater; ensuring that the make-up water used to replenish the boiler is pre-heated to near boiling temperatures, so that the boiler does not have to expend as much energy heating it to steam.

Since even small boiler systems today can be expensive to repair or replace, this innovative design adds to the overall savings and protection of the entire boiler system.
