The Japanese manufacturer Rinnai was established in the 1920s and began selling gas appliances in North America in 1974 [2]. More than 30 million Rinnai water heaters are currently in use worldwide.

Now, Rinnai US has a sizable network of certified technicians and facilities where research and training for new and seasoned salespeople and service staff is offered.

Rinnai offers two main categories of tankless heaters: condensing (SE and SE+ series) and non-condensing (HE and HE+ series). Both categories come in a wide range of sizes and may be used in any housing type.

Tankless water heaters from Rinnai are available in various sizes and include several standard features and recyclable and interchangeable parts. Therefore, if something fails, a good design makes replacement simple. No more contaminating the environment with damaged heaters, such as tank-style heaters.

All versions are small and portable and deliver infinite, constant hot water at precise temperatures. Some people call them “instant” since they heat water immediately (they do not provide water instantly, though). Recirculation systems are included in some models, like the Rinnai RUR98, to supply hot water more quickly.

  1. High efficiency and water flow

The Rinnai tankless water heaters’ high-efficiency technology allows them to operate on minimal water flow—0.4 GPM for certain models—enough for simple tasks like shaving and hand washing while saving up to 40% on electricity.

The EZ Connect system enables combining two units to function as one for homeowners who desire higher hot water delivery. A RUR series water heater is also the best option if hot water is required immediately because of its recirculation technology. Search for ThermCirc360 technology, which is present on the Rinnai RUR199 and RUR98 [6].

The moment you open the faucet and when utilizing either of the two recirculation settings, hot water is accessible. The heater with the largest water flow, RUR199, at 11 GPM, is also the most efficient (0.96).

  1. Green technology

Green technology, which offers more efficiency and less pollution, is one of the best features of Rinnai tankless water heaters.

Because it emits extremely little NOx gas, the gas burner is environmentally benign. Indoor variants use sealed combustion and have zero clearance designs. As long as you abide by the advice, which includes expert installation and use of the original venting kits, clean and safe combustion enables flexible installation inside the home when combined with a unique venting system.

  1. Modern technology

The operation of Rinnai tankless water heaters is controlled by a microprocessor, which also offers an accurate diagnosis in the event of a malfunction. The problem code will then appear on the temperature controller’s display incorporated into the device or on a remote controller given to assist users in troubleshooting.

The better versions have a voice activation system, like Amazon Alexa, Wi-Fi, and a smartphone app called Control-R that has timers, schedules, remote control, and diagnostics, giving consumers even more comfort and convenience. The Rinnai RUR98, RUR199, and RUC98 are those models.

  1. Easy installation

Outdoor variants do not need a venting system. However, indoor models must have venting. Most indoor variants use a dual or concentric vent system with one of two wall penetration sites to exhaust gases horizontally through an outside wall or vertically via the roof.

There are 14 different vent layouts for various models, according to Rinnai. Condensing model vents can be up to 65 feet long and are typically composed of PVC [8].

Isolation valve-equipped water heaters make maintenance easy when the time comes.
