Check out the benefits of the Rheem RTEX-AB7 Water Heater Booster:

  • Take long, hot showers to your heart’s desire.
  • No problem running several showers and appliances that use hot water at the same time.
  • Use the same space you already have for your 80 gallon water heater.
  • Get the equivalent of 79.75 gallons of heating capacity from a 55 gallon water heater when you add a water heater booster.
  • Save money! Purchasing a 55 gallon water heater and adding a water heater booster is a lot less expensive than buying a light-duty 80 gallon commercial water heater for residential use.
  • Miami Water Heater is a Rheem warranty shop. This means in the unlikely event that something goes wrong with your water heater booster, you can send it back to us for warranty work; no having to deal with the manufacturer.
  • And, it’s easy to install. Check out the videos below.
