Rinnai is one of the top brands in the market and an ideal tankless water heater option for homeowners in Los Angeles and the surrounding areas.

Since 2007, we’ve worked with the top brands of tankless water heaters and seen which of their products stand apart from the others. Homeowners we’ve helped install a Rinnai tankless water heater have shared how reliable their unit has been when providing hot water.

In this review, we’ll look at how Rinnai ranks in the following categories.

  • Cost
  • Efficiency

  • Additional features

We’ll first dive into discussing Rinnai’s tankless water heater costs.

How Much Does a Rinnai Tankless Water Heater Cost?

  • Rinnai units by themselves range from as low as $700 to $2,900
  • With installation, Rinnai tankless costs between $4,800 to $8,800

Rinnai’s prices tend to fall within the cost range for tankless water heaters. Depending on the unit, homeowners can pay around $1,000 for the tankless water heater by itself. The higher-end models, such as the RUCS or RSC model series, tend to lean more toward the higher price range.

Although Rinnai’s tankless water heaters have a standalone price, homeowners should calculate the additional costs associated with installation. These units aren’t simple do-it-yourself projects, so it’s recommended to invest in a reputable and certified technician to install the tankless water heater properly.

With installation, a Rinnai tankless water heater’s total cost can fall between $4,800 to $8,800. The pricing includes Rinnai’s least to most pricier tankless water heaters.

Besides pricing, another aspect homeowners should consider is efficiency.

Are Rinnai Tankless Water Heaters Efficient?

  • Rinnai’s tankless water heaters have a UEF rating of .81 to .95
  • Some Rinnai tankless water heaters qualify for California rebates and federal tax credits

Rinnai’s most efficient tankless water heater has a .95 UEF (Uniform Energy Factor). The brand’s RSC tankless water heater series all come with a .95 UEF rating and are Energy Star certified. Despite being 1% to 2% less efficient than other brands’ tankless water heaters, Rinnai can provide homeowners with hundreds of dollars in energy savings.

Some of Rinnai’s tankless water heaters have a .81 UEF rating but are still more energy efficient than conventional gas water heaters. Nonetheless, these lower UEF-rated water heaters (Rinnai RE series) don’t meet the qualifications for California rebates and federal credits available for tankless water heaters.

The more efficient options, like the RSC and RU tankless water heaters, qualify for rebates and tax credits. Regardless of which efficient Rinnai tankless water heater you choose, it’ll be backed by a standard warranty.

Rinnai Tankless Water Heater Warranty

Rinnai’s warranty coverage is similar to most tankless water heater manufacturers. Here’s a short breakdown of Rinnai’s warranty coverage.

  • Heat exchanger: The heat exchanger is covered for 12 to 15 years, depending on the tankless water heater.
  • All other parts and components: Rinnai’s warranty covers all other parts of their tankless water heaters for five years.
  • Reasonable labor: For the first year of ownership, Rinnai will cover any labor required for a warranty repair for 12 months.

A 12-year warranty is standard for most tankless water heaters, and Rinnai provides some units with an extra three years of coverage. Tankless water heaters usually last 20 years with proper maintenance, so Rinnai offers coverage up to around the time it’s time for a new replacement.

The warranty coverage for Rinnai’s tankless water heaters begins on the day of purchase and onward. Rinnai also encourages homeowners to register their tankless water heaters through their website to make future warranty claims seamless.

Are Rinnai Tankless Water Heaters Readily Available?

It’s essential to remember that this purchase only provides the tankless water heater but not the installation. Improper installation is one of the factors that can void Rinnai’s warranty. It’s recommended to have a certified technician install the unit.

Luckily, Rinnai has a network of certified installation companies that can sell homeowners Rinnai tankless water heaters and provide installation, maintenance, and repair services, too.
