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.

easier, not to mention cleaner and more aesthetically pleasing. GSW is
