Steam heat from the efficiency experts
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.
Comforting warmth, right when you want it
The cast-aluminum heat exchanger in the GWB9-IH transfers heat three times faster than conventional cast-iron heat exchangers. So you enjoy rapid warmth when you need it.
Efficiency that’s always a warm welcome
The COWB3 offers an efficiency of up to 85.2% AFUE, meaning it can deliver significant energy savings, compared to an older boiler. That means you don’t have to worry about high heating bills, no matter how cold the winter gets.
Integrates easily into your home
The GWB8-IE is available in 6 different sizes for installation nearly anywhere in your home. And if you have a traditional radiator system, the GWB8-IE will integrate perfectly to provide precise heating comfort all winter long.
Built to perform, and built to last
The heat exchanger at the heart of the GWB8-E is also designed for lasting durability, over a range of water flow rates. Burners are made of stainless steel for greater resistance to corrosion and oxidation.
Versatility that’s always a perfect fit
The GSB8-E works with your home’s existing radiator or under-floor heating system, and is available in 7 different sizes for a perfect fit nearly anywhere in your home.
