The Different Rinnai Models

Rinnai tankless water heaters use less energy and water and have an average 20-year lifespan. All parts are recyclable and replaceable.

There are three different series of models that Rinnai offers, the High-Efficiency Non-Condensing Technology, the Super High-Efficiency Condensing Technology, and the Hybrid Tank/Tankless Water series.

The High Efficiency, or HE, series has two models: HE Series V and HE +Series RL/RLX.

The HE Series V offers a low budget-friendly option for those trying to save some money. It has an energy efficiency rating of .81, and it can handle up to four running shower heads at a time. This option can be installed either indoors or outdoors and can run on natural or propane gas.

The second option in the HE series is the HE +Series RL/RLX. This is also a great budget buy option and has an energy efficiency rating of .81. This option is also good for up to four running shower heads.

This option also has Circ-Logic technology, which allows recirculation to deliver hot water faster than the HE V option. This technology also gives you Wi-Fi capability and voice activation when you connect your HE RL/RLX to your Amazon Alexa.

You are also able to control your water heater remotely. If necessary, you are able to monitor and diagnose remotely as well.

The next Rinnai series is the Super High Efficiency (SE) Condensing Technology series with the SE Series RUCS/RUS, the Sensei SE+ RUC/RU, and the RUR. All of these options are Energy Star qualified.

The SE series RUCS/RUS is a little more expensive than the HE series options. The energy efficiency rating is .81 and can support up to three running shower heads at a time.

The Sensei SE +RUC/RU series is also more expensive. This series has an energy efficiency rating at .92 and can support up to four shower heads at once. This option also has Circ-Logic technology, allowing it to have Wi-FI and Amazon Alexa capability.

This option also has the ability to control, monitor and diagnose the heater remotely.

The Sensei SE +RUR model is similar to the RUC/RU model in price range, energy efficiency rating and shower head support. It also has advanced technology, but instead of the Circ-Logic, it has the 360 technology.

The 360 technology is a more advanced version of Circ-logic, allowing all of the same features. This model is a great option for larger homes that use more water because of the ability to preheat the water.

The last Rinnai water heater series is the Hybrid Tank/Tankless Water series. This series has two options: RHS and RHS100, both are the most expensive option from Rinnai. These options do not have an energy efficiency rating, nor do they have a recommended shower head usage.

These models do offer faster hot water delivery option, and the RHS100 has the Amazon Alexa voice activation option.

It seems that the HE and SE series are the more efficient and better option for buyers.

The Rinnai water heaters come with flexible venting options for easier installation. The venting options allow for indoor or outdoor installation.

What Are Other Tankless Water Heater Options?

There are many other tankless water heaters on the market. Here are a few options to compare to the Rinnai series options.

The Rheem RTEX 13 Electric Tankless Water Heater is a compact unit that does not need a lot of power to run. It is an electric water heater, which allows people that don’t have a gas or propane option to still have a reliable source of hot water.

  • Threaded for easy replacement, simple installation, digital temperature display

The Rheem model has an impressive flow rate that allows hot water to run in a shower and kitchen tap simultaneously. It also allows you to adjust the temperature from its LED display. It costs just under $320.

If you live in a small household without gas or propane utilities lines, this model may be an affordable and reliable option.

The Stiebel Eltron Tempra Plus 24-kW is an electric heater that has advanced flow technology that allows the temperature of the water to maintain stability even if you adjust the flow rate. It is a compact and quiet water heater that costs roughly $685.

  • On-demand, continuous and unlimited supply of hot water
  • Sleek design saves space and no venting required
  • Electronic switch activated for virtually silent operation
  • Copper sheathed heating element housed in copper cylinder
  • 7 Years leakage and 3 years parts complete warranty

This is a good water heater for smaller apartments and homes and is an energy efficient unit. It does have a 3-year warranty, but must be installed by a professional technician in order for the warranty to be upheld.

The Atmor AT-D18TP-AZ Instant Tankless Water Heater is a compact, safe and user-friendly unit. The Atmor also has a water sensor that begins heating water for future use as soon as you turn on the hot water. Once you turn the tap off, the sensor goes off. This saves energy by not running unnecessarily.

The Atmor offers several models ranging from ~$130 to ~$350. All models are corrosion resistant and energy efficient. This is a very affordable option for homes with 1 or 2 people living there.

The Eccotemp FVI-12-LP Propane Tankless Water Heater is a lightweight and compact water heater that provides a great flow rate for a shower and faucet running simultaneously. It is energy efficient and runs on propane or natural gas.

The Eccotemp is a simple and user-friendly unit with an LCD screen that provide water temperature. This unit also allows for easy self-installation and costs just under $230. Because it is propane or natural gas dependent, it does need to be vented.  

How Do Rinnai Tankless Water Heaters Compare?

With the many tankless water heater options available, it seems that Rinnai still holds up to their competition.

Many other options are affordable options for small homes with one or two residents and not a lot of water usage. For the larger homes or businesses, Rinnai seems like a no-brainer.

Rinnai has several options to meet the needs of many different customers. They also offer versions for people that prefer more technology or for those that do not.

Rinnai is affordable, albeit some models are much more expensive than their competitors. A major difference and justification for the cost, is the amount of hot water the Rinnai can produce.

Many of the competitors are only good for one shower and one faucet running simultaneously. Rinnai has several options for larger homes to run multiple showers and faucets at the same time.

With Rinnai’s efficiency and many different options, this seems like a solid choice for a tankless water heater for your home or business. The only downfall is that it is only available for those with natural gas or propane availability.

Rinnai Rebates and Financing
