Prestige™ Condensing Tankless Gas

Prestige Series Condensing Tankless Gas Water Heaters efficiently provide continuous hot water with a .94 Energy Factor.

Great fit for:

  • Homes with busy families
    Enough hot water to load the laundry, start the dishes, bathe the kids and still have enough to enjoy a relaxing shower of your own.
  • Homes with luxury bathrooms
    Master bathrooms are meant to be luxurious and Rheem Tankless water heaters can support the hot water needed to bring them to life.
  • Vacation homes
    Rheem tankless water heaters heat water only when a demand for hot water is made, this helps save energy over a traditional water heating system that continuously heats and stores water in anticipation of a hot water need.

Why Rheem Prestige Tankless Water Heaters:

  • ENERGY-EFFICIENT DESIGN… Rheem Prestige Tankless models use condensing technology that allows them to be the most efficient whole home tankless water heating solution available from Rheem. Why keep 40-50 gallons of water hot when you don’t need it? It’s expensive to continue to heat and re-heat water when you’re not home or not using it. Rheem’s Prestige tankless design offers convenience and low cost operation.
  • ALL THE HOT WATER YOU'LL EVER NEED…when you need it. It's that simple. The popularity of luxury bathrooms and oversize tubs is growing, and so is the demand for large volumes of low-cost hot water. The Rheem Prestige Tankless provides a compact solution for a continuous supply of energy-efficient hot water that won’t run out.
  • COMPACT SIZE…good things do come in small packages. Rheem Prestige Tankless is significantly smaller than a conventional water heater. Sophisticated technology has reduced the size and increased the features and benefits. A digital display makes setting a precise water temperature, or monitoring the unit’s status, a snap! Its compact size will leave room for a water softener or extra storage.
  • PRECISE TEMPERATURE CONTROL Many user and installer-friendly features make the Rheem Prestige Tankless the easiest tankless water heater to own. The digital display makes it simple to set the water temperature. Simply set the desired temperature and walk away. Because the water is heated only when it is needed, the outgoing water temperature remains constant.
  • SELF-DIAGNOSTIC Should maintenance be required, the unit’s self-diagnostic system will display a maintenance code, which makes troubleshooting less expensive.
  • EZ-LINK™ CABLE EZ-Link cable connects two tankless units to operate as one – now available for high demand applications.
  • RHEEM QUALITY We are committed to providing the highest quality product to customers. The Rheem Tankless is no exception. The specially designed features have been field and laboratory tested to ensure consistent, precise operation to meet our quality standards.
