Rinnai Tankless Water Heater Reviews

Welcome to our Rinnai Tankless Water Heater Reviews Guide. 

Rinnai have a solid 45 year accomplished history in the United States and are forerunners in the tankless water heater industry – arguably the best tankless water heater brand in the world. They have built a brand based on reliability, quality and innovation and their market leading gas appliances are incredibly efficient and environmentally friendly. If you are looking at replacing your hot water system or planning the construction of a new home, congratulations first of all for considering a tankless hot water tank. The benefits of going tankless extend far and wide, primarily on your energy consumption (consequently saving you money) and the environment. When comparing a traditional hot water system to a tankless on demand water heater system, the pros far outweigh the cons and Rinnai will not disappoint. They have an extensive range of tankless water heater gas systems and design and manufacture some of the best tankless hot water heaters on the market.

We seek to provide comprehensive and informative reviews and we hope you have gained valuable insight by visiting our Rinnai Tankless Water Heater Reviews Page. If you have any questions, please do not hesitate to get in touch with us!

Before we get started take a look at the Youtube clip by Rinnai explaining the tankless hot water heater concept!

Rinnai Tankless Water Heater Features

All of Rinnai Tankless Water Heater models feature impressive recirculation technology, ThermaCirc360, which enables the water to recirculate between your Rinnai on demand water heater through the line and back to the heater, giving you instantaneous hot water on demand. It is so sophisticated that you can set your recirculation schedules in accordance with your peak hot water demand times or you can use on-demand recirculation via push buttons and motion sensors. Check out the Youtube video for a visual explanation.

Wifi Technology

All of the Rinnai Tankless Water Heater models featured in our Rinnai Tankless Water Heater Reviews guide are Wifi capable which can be purchased as an added feature. Simply attach the wifi module to your tankless water heater, download the app and control and monitor your hot water from anywhere in the home. The wifi module allows you to adjust the temperature, receive maintenance alerts, run diagnostics and activate the recirculation system.

Energy and Cost Savings

The benefits of going tankless are numerous; standard tanks are still very common in the United States so I’m sure that you have probably experienced the frustration of your hot water supply running out, leaving you with cold water until such time that the tank refills and reheats. This will never occur with a Rinnai Instant Hot Water Heater because the design of the tankless system heats the incoming ground water when hot water is required. When the hot water is no longer required, the instant hot water heater will efficiently shut off until hot water is needed again. This feature contributes to overall efficiency measures of the Rinnai Instant Hot Water Heater.

Another premium feature of the Rinnai tankless system includes the digital controller; this device enables you to to set a specific water temperature and the tankless water heater intelligently adjusts the flame output to ensure the precise temperature is maintained essentially reducing energy consumption and costs for your household.

The energy factor, or as of June 2017, the UEF of the Rinnai tankless systems are far better (ranging from .82 – .96) than its standard tank counterparts (approximately .60-.70 for standard 50 gallon tanks) and annual costs to run an instant hot water heater are far less than a traditional hot water tank.
