GSW Water Heating
A leader in residential and commercial water heaters, GSW has evolved from a wood-burning stove company to a world-class designer and manufacturer of electric, natural gas, propane and oil fired water heaters. Backed by the company’s manufacturing history of more than 150 years, GSW is recognized for design innovation and exceptional reliability.
Professionals recognize GSW brand names, such as John Wood®, for their unrivaled quality, efficiency and reliability. In fact, contractors have been trusting John Wood® for more than 50 years.
The new John Wood® Signature Series has been specifically designed for the needs of the professional installer. Our new gas models now deliver lower profiles for easy installation and maintenance, as well as smaller vent diameters and ultra-accurate dual electric thermostats for precision and control. What’s more, our Signature Series electric models are custom built-to-order to ensure your exact specifications are met. All our heaters offer advanced features such as TankSaver® stainless steel inserts and glass-lined tanks for longer life.
