GWM-IE Boiler

High-Efficiency
Gas-Modulating Condensing Water Boiler
 
Design that’s highly innovative and efficient. The GWM-IE boiler offers an efficiency of up to 95% AFUE, meaning it converts up to 95% of its fuel into useable heat. Fuel flexibility lets you use either natural or LP gas as a heat source. With an efficiency of up to 95% AFUE, the GWM-IE boiler can mean several hundred dollars per year in energy savings.This product has been designated as one of the Most Efficient ENERGY STAR certified products in 2018. 
 
Inside the heat exchanger shell of the GWM-IE, specially designed helical tubes optimize condensing, allowing near-complete recovery of useable heat from the fuel source. The modulating capability of the GWM-IE allows the burner to fire at different levels of heat, down to 20% of its full capacity. So your comfort and energy use are always kept in perfect balance. ontinuous modulation allows the GWM-IE to maintain a precise temperature without constantly cycling between on and off. This not only reduces operating sound levels, but it also increases reliability.
