Explore the Types of Rinnai Tankless Water Heaters

Depending on your needs, Rinnai has a variety of water heaters available, including non-condensing, condensing, outdoor and indoor installation, commercial choices, and various fuel sources.

Condensing Water Heaters

Condensing water heaters operate similarly to non-condensing ones. The tankless heater receives cold water from the faucet, which sparks the flame in the condensing water heater. 

During its passage through the stainless steel heat exchanger, the water pre-heats and continues to warm up during the remainder of the process.

For example, you can try Rinnai RU199iN Water Heater which will ensure the best experience for a condensing water heater. A condensation trap and drain that are incorporated into the unit, various venting systems, and a secondary heat exchanger are the distinctions with a Rinnai condensing unit.

Non-condensing Water Heaters

Turning on the cold water tap and letting it run into the tankless heater is how a non-condensing tankless water heater operates. 

Moreover, the heat exchanger’s copper coils ignite the flame, warming the water as it passes through them before entering your pipes and the target appliance. According to the required temperature, it can be able to adjust the flame.

In this regard, you can consider the Rinnai RL94iP Water Heater. The hot gases from a non-condensing hot water heater will be vented outside. 

The efficiency of non-condensing water heaters is typically around 80%, which means that 20% of the heat is lost. So, non-condensing water heaters are less expensive.

Indoor Installation

Tankless water heaters are excellent for saving space because many of them are around the size of a carry-on bag.

This capability is crucial for installations indoors in particular. For the best performance and most efficient use of space, you can try Rinnai V75iP Water Heater which will ensure the best indoor installations use concentric venting, in which one pipe lets fresh outdoor air in and the other one lets exhaust out.

Outdoor Installation

The option of indoor or outdoor installation must be made at the time of purchase in many units because it is often non-interchangeable. 

The biggest benefit of installing water heaters outside is that there is no need for venting, which can add to the expense. In this regard, you can go for Rinnai V65eN Water Heater to get the best outdoor tankless water heating solution. 

For safety reasons, outdoor installation is not advised in places with extremely high temperatures or where they might be near electricity lines.

Which Factors Should You Consider Before Buying a Rinnai Tankless Water Heater?

It’s crucial to figure out the amount of Rinnai tankless water heater you require. A heater that is too tiny won’t be able to supply your home with enough hot water, while a heater that is too big will cost you money you don’t need to spend. 

How much water will you need when there is a high demand, such as when a load of laundry is being washed, the dishwasher is running, and you are having a shower? How much fresh water will be required to be heated in order to meet the demand?

Before investing in a Rinnai tankless water heater, you should take into account two factors: the flow rate, or the amount of water used by a fixture or appliance measured in gallons per minute (GPM), and the temperature rise, or the difference between the temperature of the groundwater and the desired hot-water output temperature.

Flow Rate (GPM)

List all of the appliances or fixtures you’ll be using concurrently during peak demand, such as running the dishwasher, a load of laundry, and the shower. In this regard, you can calculate your hot-water requirements. The overall flow rate is then calculated by adding each individual flow rate.

For information on flow rate, consult the manufacturer’s manual for the fixture or appliance (shower head, dishwasher, washing machine, etc.), or look for the GPM stamped on the item itself. 

Using a bucket and timer, you can also quickly determine the GPM of a device or fixture by using the following formula: 60 divided by the time it takes the appliance or fixture to fill a 1-gallon container with water.

Temperature Rise

The typical temperature of the water inside a residence is between 110 and 120 degrees. Subtract the desired internal water temperature from the incoming water temperature to get the temperature rise. 

For instance, the temperature rise is 63 degrees if the incoming water is 57 degrees and the shower water temperature is 120 degrees.

In addition to knowing the flow rate and temperature rise before buying a Rinnai tankless water heater purchase, check to size charts to help you decide which heater will best meet your needs.

Installation and Maintenance Cost of Rinnai Tankless Water Heater

Depending on the model, Rinnai tankless water heaters range in price from $500 to $2,300 and have a 10- to 12-year warranty. Additionally, Rinnai provides an optional Wi-Fi module that enables users to control their tankless water heater using an app on their smartphone.

Professional tankless water heater maintenance often costs $50 to $400 per visit. To save money, you can perform maintenance on your own. The cost of maintenance for Rinnai tankless gas water heaters ranges from $200 to $700. 

Leading manufacturer of high-end tankless heaters, Rinnai is known for producing gas-powered units that frequently have a smart connection and Wi-Fi controls. The high efficiency of Rinnai heaters makes them perfect for those who want to use less energy. They are susceptible to faulty valves, thermostats, and pilot light assemblies, just like any other heater.

How long do Rinnai tankless water heaters last?

A Rinnai tankless water heater has a life expectancy (or useful lifespan) of up to 20 years. Water quality, use, and correct upkeep have an impact on real life. A tankless water heater is more cost-effective in the long term because it lasts nearly twice as long as a tank water heater.

Some Drawbacks of Rinnai Tankless Water Heaters

Compared to conventional tank-style water heaters, Rinnai tankless water heaters have a number of benefits. What are some of the drawbacks of the Rinnai hot water heater, despite the fact that it offers many advantages? Here are a few drawbacks of these water heaters:

  • Comparatively speaking to traditional heaters, Rinnai tankless water heaters are more expensive to buy and install. Even if the initial cost is higher, you will spend less overall on energy costs.
  • A tiny unit might not have the capacity to meet a household’s demand all at once. A large Rinnai tankless unit, which is more expensive, is required if you have a large family that uses the appliance simultaneously.
  • Tankless electric water heaters will stop heating water if there is a power loss, in contrast to gas water heaters, which will continue to function even if your electricity goes out. Unfortunately, if you do encounter prolonged power outages, this can be a problem.
