GSW Signature Series Electric manual John Wood by Noritz

John Wood® by Noritz

Tankless for professionals.

Residential Models

John Wood® residential water heaters by Noritz are designed to provide abundant hot water for the entire home. All residential tankless water heaters are backed by a 10-year warranty.

Commercial Models

Commercial tankless water heaters use commercial grade materials, such as a coated copper heat exchanger and 25% thicker piping than the residential models, making John Wood® commercial water heaters unique. Up to 24 can be linked with a system controller to provide abundant hot water for heavy industrial applications.

Direct Vent, Sealed Combustion Models

John Wood® offers Direct Vent models for use in areas where combustion air from indoors is not available, such as spas, hair salons, or air tight spaces. John Wood® Direct Vent models take air from outside for combustion. The John Wood® line includes the only commercial Direct Vent unit on the market. This unit has a coated copper heat exchanger and 25% thicker piping than residential models to ensure years of service.

Quick-Connect

All John Wood® commercial, direct vent and most residential models are Quick-Connect compatible, allowing two units to be installed in series, doubling water capacity when needed.
