Most Infinity units are compatible with natural gas. However, homeowners can use propane if that is their preference.

Functions & Features

Despite the various models of tankless water heaters that run on gas, most heaters have common features that include;

• Electronic ignition: The water heater employs electronic ignition to start the combustion process, which replaces the traditional pilot light. The ignition is safer and more energy-efficient. It also boosts the unit's performance by lowering gas consumption.
• Advanced modulating burner: The modulating burner technology provides precise gas control. It optimally adjusts to water and gas pressure fluctuations to ensure constant water temperature. Moreover, the technology enhances water heater efficiency by minimizing gas consumption.
• Temperature controls: The gas tankless water heater has temperature control features with thermostats and digital control to ensure safe and consistent water temperature. Users can set and monitor the temperature easily.
• Flow rate: A Rinnai gas tankless water heater offers numerous options in various models to meet different users' water needs. The flow rate is measured in gallons per minute (GPM) and may vary depending on the number of fixtures and appliances to be connected.
• Environmental protection: The water heaters reduce harmful gas emissions for cleaner air and enhanced environmental protection. They lower nitrogen oxide emissions below the EPA's standard for improved air quality. Also, the heaters have energy-efficient features that help minimize greenhouse emissions.
• Variable water pressure: The unit operates under different water pressure conditions, with some models having a pressure boost feature. It maximizes performance in low water pressure by enhancing water pressure delivery.
• Heating modules: The water heater has multiple heating units or modules, which can be a single or more, depending on the model. Each heating module can work independently to provide hot water.
• Controllers: Rinnai tankless water heaters have user-friendly control systems that allow users to operate the heater, set the temperature and monitor performance.
• Venting options: The water heaters offer a variety of venting options, which include direct, power and conventional. They allow proper exhaust of harmful gases depending on the installation requirements.

Scenarios of a Rinnai gas tankless water heater

Gas tankless hot water heaters are good options for many commercial and industrial applications because they are durable, efficient, and easy to operate. Here are some common use cases of these heaters:

• Food industry

  In restaurants, gas tankless water heaters can supply hot water for various food preparation tasks. Over the years, food businesses have preferred tankless heaters because they are more energy efficient than storage heaters. Tankless models also take up less space. With a proper flow rate, a gas tankless heater can provide continuous hot water during busy hours.

• Laundry facilities

  Large laundry facilities require a lot of hot water for washing and rinsing. Gas tankless heaters are a practical solution to this need. The constant hot water provided by the heater improves the efficiency of laundry operations. Since many laundries are located in colder areas, the high heating power of gas units is ideal. Also, the small size of tankless heaters makes installation easier, especially in older buildings.

• Medical centers

  Hospitals and clinics have various departments that need hot water for cleaning. Typical examples are the surgery and maternity wards. In these medical facilities, having a constant supply of hot water is critical for good hygiene practices. Therefore, many healthcare providers install tankless water heaters to avoid storage tank systems' potential hot water shortages and hygiene issues.

• Distillation plants

  Gas-fired tankless water heaters are often used in industrial distillation to heat liquids before reaching the boiling point. The precise temperature control and high heating power of tankless units make them suitable for this application.

• Schools

  In school buildings, gas tankless water heaters are installed to supply hot water for various sinks. The heaters provide sufficient hot water for handwashing in school clinics and cafeterias. Some schools also use these water heaters for light space heating during chilly days. Tankless water heaters are a good fit for schools because they reduce energy costs and occupy less space than traditional tank heaters.

How to choose rinnai gas tankless water heater

Wholesale buyers need to consider various factors before ordering Rinnai gas tankless water heaters. First, examine the water heater's capacity to meet peak demand. Conduct a detailed study of the target customers and their typical water usage patterns. Order a unit that can fulfill the average demand and settle on the unit's flow rate and the number of fixtures.

Next, consider the unit's energy efficiency and operating costs. Rinnai units with more efficient burners and better insulation will consume less gas and lower customers' utility bills. Such units will also qualify for tax credits and rebates. Investigate each gas heater's energy efficiency rating and look for features like a modulating power burner and demand-activated operation.

Remember that these units require routine maintenance to operate safely and efficiently. Find out each unit's maintenance needs and the skill level needed to carry out these tasks. Opt for units with self-cleaning and easy-to-replace filter features.

Next, check the Rinnai units' compatibility with the existing ventilation system. Review the units' venting requirements to ensure they fit the installation environment. Also, ensure that the heater complies with local plumbing codes and regulations. Learn about any permits or inspections required for gas heater installation. Review each unit's warranty and after-sales support. Make sure that the supplier provides adequate coverage and support to wholesale buyers.

Finally, evaluate the unit's installation requirements and costs. Compare the difficulties and expenses associated with installing a tankless heater with a tank model. Consider the size and weight of each unit, and check if it requires special handling during installation. Review the different heater models to be sure they offer distinct features and capabilities. Evaluate the pros and cons of each unit and how they meet various customer needs.

Rinnai gas tankless water heater Q&A

Q1: What are the disadvantages of a tankless gas hot water system?

A1: Tankless water heaters can be more expensive initially and might need more maintenance. Their installation is different from that of tank heaters, which can increase the cost. They also require complex ventilation because they run on gas, and their failure can lead to an entire hot water system breakdown.

Q2: How do tankless water heaters save money?

A2: Tankless heaters only run when hot water is needed, unlike tank models, which constantly heat water in the storage tank. This can lower the energy bill by as much as 20-40% annually. Additionally, these units use electricity and gas more efficiently, further lowering utility costs.

Q3: What maintenance does a Rinnai tankless water heater require?

A3: Rinnai recommends scheduling annual maintenance with a licensed professional to keep the unit running safely and efficiently. Maintenance may include checking the water filter, viewing the gas and water connections, testing the safety shut-off, inspecting the venting, and flushing the heat exchanger to remove mineral buildup.

Q4: How long do Rinnai tankless water heaters last?

A4: With proper maintenance, Rinnai gas tankless water heaters can last over 20 years. The company offers an industry-leading warranty on its tankless units, covering most components for 12 years if installed by a qualified Rinnai dealer.

Q5: Can I use my Rinnai tankless water heater during a power outage?

A5: This depends on the gas line. If the water heater is gas-powered and the gas line is working, it can run during a power outage. However, if it is a gas unit with electronic ignition, it will not work without power. Tankless water heaters that run solely on electricity will not operate during a power outage.
