Natural Gas Ultra Low NOx Water Heaters - Direct Vent

Ultra Low NOx Direct Vent (DS) water heaters utilize a co-axial (pipe inside a pipe) vent pipe that takes air in from the outside (outer vent) and vents combustion gases directly back to the outside (inner vent). It is the perfect choice for situations with insufficient combustion air. No electricity required.
