Tankless Water Heaters
- Tankless water heaters can be installed on virtually any wall inside or outside of a home.

design flexibility.

Right Product, Right Time
Today, many homes that you build feature large bathrooms with luxury spa baths and other amenities. Natural gas tankless water heaters can provide your customers with an endless supply of hot water and provide you with a competitive edge.
More and more of your customers are demanding green products. Natural gas tankless water heaters are also environmentally friendly. In fact, they were named as one of the “Top Green Products” by Building Products Magazine.
Flexible Installation and Venting Options
Tankless water heaters can be installed on virtually any wall inside or outside of a home—even in a garage, basement, or laundry room.
Interior units vent directly to the outside. Indoor tankless water heaters can be vented vertically or horizontally to the outdoors. Exterior units require no venting and can be installed in a recessed enclosure or flush with the outer wall.
Design Flexibility and Space Savings
Tankless water heaters can be used individually, in pairs, or in banks of three or more. For most homes, one unit can supply enough hot water to meet the needs of the household.
Tankless water heaters take up very little space. Conventional systems can take up to 16 square feet of floor space.
Tankless water heater advantages:
- Significant space savings compared
to conventional tank water heaters - Indoor and outdoor installation options
- Multiple venting options
- Flexibility to meet hot water demands of any size home
- Green product
- Life span up to twice as long as conventional tank systems
Design considerations
Before you install a tankless system, there are a few design considerations to be followed:
- Natural gas fuel lines are typically ¾-inch MNPT.
- The water line is typically ¾-inch diameter.
- The unit should be placed close to the point of use for maximum performance.
- Make sure the gas utility knows the potential load so the gas meter can be sized properly.
- Follow installation instructions and include additional water valves for routine maintenance.
