Rinnai Tankless Hot Water Heaters

Rinnai Logo

Tankless water heaters revolutionize the way you use hot water. They produce more hot water, at a more consistent temperature, using less energy than typical tank-style water heaters.

Reasons to go Tankless

  1. Because tankless water heaters provide hot water only when it’s needed, they can save you up to 40% on your energy bill. They feature Energy Factors of 0.82 up to 0.96, while tanks are typically 0.60.
  2. Tankless hot water heaters do not store a large volume of hot water that can be depleted, but rather heat the water as it’s being used, giving you endless comfort in the form of continuous hot water at a consistent temperature. You can even use hot water for multiple tasks—such as showering, washing dishes or doing laundry—at the same time without worrying about running out.
  3. Traditional tank water heaters can take up to 16 square feet of floor space. Tankless water heaters, however, are a fraction of the size and can be installed on virtually any wall.
  4. Tankless water heaters have a typical life expectancy of up to 20 years.

Facts About Tankless Water Heaters

The ideal size of your tankless water heater will depend on the number and type of plumbing fixtures and appliances you have, and the groundwater temperatures in your area. It will also depend on how many people are in the household.

A typical tankless water heater comes with a temperature controller that you use to adjust the water temperature (within a safe range, typically from 98° F to 140° F). The controller also displays diagnostic and maintenance codes to help you monitor system performance.

There are two types of simple, periodic maintenance that you or your service technician should consider to keep your tankless water heater running optimally: Checking the in-line screen filter for debris, and flushing the tankless water heater to keep it free of scale and lime.

A tankless water heater will typically cost two to two-and-a-half times as much as a conventional tank-style water heater. However, energy savings and lifestyle benefits can make it a better long-term investment over a tank.
