How to Use Rinnai Tankless Water Heater
Consider the following before purchasing a Rinnai water heater. How should the unit be operated safely, how should the temperature be changed, and how should the temperature controller be used appropriately for monitoring?
Advanced technology
- As soon as your Rinnai tankless water heater has been professionally installed, it is important to learn how to use it properly for dependable, long-lasting, and safe heating.Rinnai tankless water heaters are smart; they use a small computer to supply hot water for as long as it is required, on-demand and in continuous supply, and at a preset temperature.
- Because the temperature of the entering water fluctuates from summer to winter, Rinnai regulates the water flow to maintain a consistent temperature of the exiting hot water from the boiler.
- The modulating gas valve allows the heater to increase or decrease its power during the heating process, depending on the demand and the temperature that has been set for the heater.
- Rinnai
Ignition
Tankless units are equipped with direct electronic ignition, which eliminates the need to manually start the fire (since there is no pilot light) because the device instantly ignites the burner when the unit is turned on. The gas will continue to burn as long as there is a need for hot water or as long as the faucet is open.
Venting
Direct venting is used by these units, which means that they draw combustion air from the outside and exhaust flue gases to the outside at the same time.
Manual gas valve
In order to turn on the gas, a manual gas valve positioned near the water heater must be twisted counterclockwise to the fully open position. It was presumed that the valve was closed and not in use.
Isolation valves
It is recommended that the isolation valves provided with the water heater be put on both the cold and hot water lines in order to isolate the unit and perform servicing or maintenance, such as flushing, on the unit.
Water flow
It is recommended that the isolation valves provided with the water heater be put on both the cold and hot water lines in order to isolate the unit and perform servicing or maintenance, such as cleaning, on the heater.
Using the temperature controller to set the temperature
- The temperature controller MC-91-2 from Rinnai is built into the front of the unit on the majority of indoor water heaters, although it is not included with the company’s outdoor versions.
- The controller is not included with the V53 series of computers.
- In addition, the controller makes it simple to monitor and manage the temperature of hot water, and if something goes wrong with the device, its diagnostic system will identify the issue by displaying an error code.
- To switch on the electric power to the device, press the ON/OFF button on the unit’s control panel.
- Make sure the thermostat is set to the proper temperature.
Indoor water heaters are supplied with a control panel that is comprised of an LCD display and a number of buttons for operation.You have the ability to switch the device on or off, as well as increase and decrease the temperature (in F and C).In response to your pressing of the ″Priority″ button, a green light will illuminate, indicating that your controller is controlling the temperature and that your water heater is ready to use.Rinnai water heaters operate in the temperature range of 98 F to 140 F, with the factory setting of roughly 120-125 F.They are available in a variety of sizes.Additionally, the temperature controller MCC-91-2, which is mostly utilized in commercial applications and has a maximum temperature of 185 F, is available for usage to achieve greater temperatures.
A maximum of four controllers can be installed on a single computer.
Controller and diagnostic codes
- In addition, the most advanced Rinnai tankless water heaters are capable of diagnosing internal problems and displaying the diagnostic number on the LCD panel.
- Diagnostic codes are represented by the numbers 03, 10, 11, and 14, and each code indicates a problem, such as a lack of flame, defective sensors, or a vent obstruction.
- Additionally, the controller may provide you with some useful information, such as the flow rate of the water or the temperature of the outgoing water.
Choosing the right temperature
- While water is heated over 125 degrees Fahrenheit, it can cause damage, thus extra caution should be exercised when children and the elderly are bathing.
- For example, only 3 seconds of hot water immersion at 140 degrees Fahrenheit is required to cause first-degree burns.
- It is necessary for the heater to work at a minimum flow rate; otherwise, the device will not operate or will provide hot water at a temperature that is constantly changing.
- In addition to using a temperature controller, you may also set and modify the temperature manually.
- Nonetheless, the default temperature is 120 degrees Fahrenheit, and it may be increased to 140 degrees Fahrenheit by altering the dip switch.
Make sure to disconnect the device and drain all of the water if there is a power failure during the cold days.Providing your water heater is connected to an electric power source, the equipment will not become faulty.

Can Water Heaters Be Installed Outside: What You Should Know
- Every family relies on hot water to function properly. Tank water heaters take up a significant amount of room in a home. They are large and hefty, and if a leak occurs, they may cause significant damage. Homeowners are constantly on the lookout for the most effective way to conceal a water heater, even if it means placing it outside. Depending on the circumstances, you may be able to put water heaters outside. Electric and natural gas tank-style water heaters are not intended to be put outside in the elements without protection. Gas tankless water heaters, on the other hand, are available in variants that are put outside. Electric tankless water heaters can also be installed outside, however some form of protection is suggested to keep the device protected from the elements. To elaborate, the decision to put a water heater outside is based on two primary considerations: your geographical location
- the type of water heater you have
We will examine into tankless and tank-style water heaters that are powered by gas and electricity.
Where to Install a Tankless Gas Water Heater
- Because they are small and energy-efficient, tankless water heaters are becoming increasingly popular because they provide an almost limitless supply of hot water.
- The primary motivating force is the availability of water on demand.
- Tankless gas water heaters are available in both outdoor and interior configurations.
- Because the units are customized for each installation technique, you must know which method you will be using before making your purchase.
- In other words, you can’t put a tankless water heater in the basement and then move it outside.
You can identify the difference between the two depending on the amount of venting they produce.In the front of the tankless outdoor units is a built-in venting system that helps to circulate air.The top of the indoor tankless water heaters must be equipped with a vent flue attachment.External tankless water heater types are suitable for outdoor installations, such as on the outside of your home’s outer wall.On the front of outdoor heaters, there is a built-in vent for ventilation.Tankless water heaters for indoor use must be installed within a building.
They are not as durable as outdoor models when it comes to extreme weather conditions.They are often put within a garage with venting to the outside, which is typically accomplished through an external wall.In most cases, tankless water heaters are installed on the interior side of an outside wall in an indoor installation.Even though it’s unusual, installing a generator in a basement, internal room, or attic is an alternative.
A garage is a common site for installing new equipment.The most crucial factor to consider is the adequate venting of exhaust gases to the outside environment.These approaches often comprise the installation of a tankless water heater in conjunction with a recirculation system and a storage tank for hot water.Both outdoor and indoor gas versions generate the same amount of hot water output in gallons per minute (GPM), which is due to the fact that the incoming cold water temperature impacts hot water production more than the location of the unit.Insider’s Suggestion: When installing an outside unit, keep in mind that it should not be positioned within four feet below or to the side of, and one foot above, any door or operable window that may be opened, according to regulation.
This is done in order to keep carbon monoxide from invading the residential area.
Where to Install a Tankless Electric Water Heater
- Trash-can-style electric water heaters are becoming increasingly popular, especially in compact places such as tiny homes, flats, condominiums, and recreational vehicles.
- Other applications include outdoor places such as pool houses and outdoor showers, where a high volume of hot water is not required at all times.
- Electric units are available for installation throughout the home.
- However, you must carefully review the specs of these units because they have restrictions and may be quite expensive to operate if there is a high demand for hot water.
- These units, on the other hand, have proven to be particularly useful in compact areas, such as those with only one bathroom and one kitchen.
When it comes to a whole-house solution, I would not suggest them for a household of more than two people.You have the option of installing an electric unit outside.We propose that you build a shelter to keep it safe from the rain and cold weather.Outdoor kitchens, pool houses, and outdoor showers are examples of applications that are ideal.When compared to tank variants, both gas and electric models offer significantly higher energy efficiency.Are you looking into purchasing a tankless water heater?

Can You Install a Tank Water Heater Outside
- Tank water heaters, whether electric or natural gas, should not be installed in exposed outdoor places without protection.
- Installations in the garage, storage area, attic, or other interior locations are recommended.
- There are some exceptions to this rule.
- It is possible to put them in an outdoor water heater enclosure or a weatherproof shelter if you live in a warm region with no hard winters.
- In chilly weather, outdoor places are not the ideal choice.
Tank versions, in contrast to tankless models, make water heating more difficult and less energy efficient.An outdoor water heater enclosure, on the other hand, is not required for all tank water heaters.The diameter of the water heater cannot be more than 30 inches, which eliminates several models from consideration.Typically, these enclosures can accommodate a water heater with a capacity of up to 80 gallons.Galvanized steel enclosures are not often recommended since they are not designed with a back and are not typically sealed or insulated, as is the case with aluminum enclosures.Because it is built up against the house, the steel enclosure does not have a rear.
These enclosures are also susceptible to leaks caused by rainwater, which can result in the rusting of the tank’s outside.In the event that you plan to install a water heater outside, within a galvanized steel enclosure, we recommend that you do not place the water heater directly on the ground.If you want to avoid water collecting in the bottom of the enclosure and rusting out the tank, you may build a raised platform out of steel or purchase a steel elevated water heater stand.Water should not be allowed to pool in the burner chamber of a gas water heater, for the same reason.
Additionally, if you want to place a water heater in an outdoor storage building, you should consider utilizing a water heater blanket to keep the temperature stable.It is possible to conserve floor space by locating a tank water heater outside; but, you will lose some of the energy-saving benefits.When tank-style models are installed outside, the energy prices might rise as a result of the increased use of electricity.
Can a Heat Pump Water Heater be Installed Outside
- Heat pump water heaters are not permitted to be installed outside.
- Because of the significant variations in temperature of the air surrounding the water heater, these units are not suggested for use in unheated locations such as garages, where they would rely more on the electric mode.
- Heat pump models, which are taller than tank models, should, in theory, take up more room than tank models.
- They also require more area in order to function properly; manufacturers recommend 100 square feet in order to ensure adequate airflow around the device.
- As a result, a laundry room or a mechanical room would be the appropriate location.

Common Areas Water Heater can be Installed
Tank-Style Water Heater
- A tank-style water heater may be installed just about anyplace in your home, even the basement. The most often encountered regions are as follows: Garages are unheated facilities that are linked to a house.
- Underpinnings — unfinished and completed compartments that are typically used to store mechanical systems
- In the case of attics, they are unfinished areas above the living space.
- Tank heaters, on the other hand, can be installed inside your home for several reasons: Kitchens – Metal box cabinets with a small water heater were typical in earlier homes, and they were usually made of metal. Other places where you could find it include behind sinks and within cupboards beneath counters.
- The hot water heater in the bathroom is also a regular sight in older homes, when it would be hidden away in a closet. The hot water would be delivered to the fixtures more quickly
- Laundry rooms – which are frequently located beside the clothes washer
- Interior closets, such as those found beneath stairwells or in hallway closets
- and
Tips from the inside: Keep in mind that interior units must have a drain pan with a discharge line that leads to the outside of the home. Gas water heaters also require an 18-inch platform to raise the water heater and shield the burner chamber from dangerous fumes, as well as a stop post to ensure that the water heater does not overheat (inside a garage).
Tankless Water Heaters
As previously stated, the tankless water heater is available in two different variants. Outdoor variants must be installed on the outside of your home, while indoor models must be installed on an interior surface and vented to the outside.
Exterior Tankless Water Heaters
- First, let’s have a look at some outside models.
- For warmth and aesthetic reasons, it is recommended to put an outdoor tankless water heater on a sunny sidewall that is not clearly visible from the street.
- Tankless water heaters that are mounted on the outdoors must maintain the highest possible temperature, especially during the winter.
- It is also necessary to insulate the water supply lines in order to prevent them from freezing.
- Many customers choose to cover their tankless water heaters with fences or other attractive coverings in order to conceal them and increase their curb appeal.
Interior Tankless Water Heaters
- The installation of an indoor unit might take place in garages or basements.
- Some installations are in attics, while others are in inner rooms along the interior side of an outer wall, despite the fact that this is unusual.
- As previously stated, the indoor tankless water heater must be installed on an external wall in order for it to be able to vent to the outside.
- Attics, on the other hand, are an anomaly since, like a gas furnace, venting via the roof is a possibility.
- Indoor tankless units may be installed to wood framing in the attic in the same way that they can be put in other interior spaces.
Conclusion
- When purchasing a new home or just looking for a new water heater to install in your existing home, take into consideration the placement of your existing water heater.
- Professional installation is recommended when you need to make changes to the plumbing in order to reach your desired results.
- The installation of a water heater by a qualified professional will give years of dependable service (with routine maintenance).
- Tank heaters should be installed indoors wherever possible.
- In either case, a water heater, even if it is installed outside, can endure for many years.

What is The Advantage of a Tankless Water Heater
- A tankless water heater, like any other product you could purchase, will come with its own set of advantages and downsides that are specific to that product. A growing number of homeowners are making the decision to install tankless water heaters in their homes, and many people are asking what all the excitement is about. Now, let’s take a look at some of the benefits that tankless water heaters may provide: Purchase and installation of a gas-powered, tankless water heater will result in a $300.00 federal tax credit for the purchaser. It may also entitle you to a number of state tax breaks and exemptions.
- A tankless water heater will provide you with an almost limitless supply of hot water. A typical water heater, on the other hand, will only hold an average of 40 gallons of hot water at a time. You must wait 30 minutes or longer for the hot water to refill itself and reheat the water once it has run out.
- The typical lifespan of a storage water heater is 10 to 12 years, depending on the manufacturer. According to the manufacturer, the typical lifespan of a tankless water heater is 15 to 22 years.
- In comparison to traditional models, tankless devices are more energy efficient, which is better for the environment, because they do not require additional energy to keep water warm. This eliminates the need for any standby heat loss
- The majority of current tankless water heaters have small designs that allow them to be put in unconventional areas such as a crawl space or an attic, as long as they are not exposed to the elements or extreme temperature fluctuations.
- A tankless heater consumes just the amount of energy necessary to heat the volume of water that is required at any one moment.
- Installing one of these units in your house can cut your monthly energy expenditures by as much as 20 percent to 45 percent on an annual basis.
- Water heaters operated by electricity do not emit greenhouse gases, which have been shown to be hazardous to the environment. Most models include precise temperature controls, which allow customers to raise or drop the temperature of their hot water in one-degree increments. In fact, several versions come equipped with easy remote controllers.
- In addition, because tankless heaters do not have a water tank, they lessen the likelihood of flooding in the home, which occurs frequently when a tank ruptures or rusts.
The Energy Factor
- Generally speaking, a tankless water heater consumes 25 to 50 percent less energy than a storage water heater, which can result in an annual savings of roughly $100.00 for the average household – depending on how much water they use.
- The tankless water heater (also known as an on-demand water heater) saves energy by only heating water when a faucet is opened.
- This reduces the amount of water wasted.
- The vast majority of tankless heaters are fueled by propane or natural gas, with only a tiny proportion powered by electricity.
- The greatest advantage is that they remove the costs involved with storing 40 gallons of hot water in a holding tank, which decreases the amount of energy that is wasted by your home during the heating and cooling process.
Because an on-demand water heater provides an unending supply of hot water, it is the most efficient means of filling a soaker tub or whirlpool tub in your home.
The Downside
- Tankless water heaters are not without their drawbacks, despite the numerous advantages they provide.
- Acquiring and installing a tankless water heater is too expensive for many households, which is the primary deterrent to purchasing and installing one.
- The initial outlay of money might be deterrent.
- Point of use (also called as on-demand) models are often priced around $500.00; however, a single POU model is typically only capable of serving one or two faucets at a time, depending on the type.
- Taking a hot shower while running the dishwasher, for example, might result in a lack of available hot water.
Consequently, a homeowner must choose between purchasing numerous POU models or purchasing a more expensive whole-house model.However, while whole-home versions are more powerful than their point of use siblings, the cost of running them is much higher as well.Because the majority of tankless versions have high-capacity burners, proper ventilation is necessary.Consider the fact that, in the vast majority of situations, installing a gas-powered whole-home tankless water heater would involve the installation of a sealed, specialized venting system, which will require expert installation.Gas-powered heaters sometimes need the installation of a correctly sized gas line, which increases the overall cost of the installation.
In Conclusion
- There are several advantages to tankless water heaters, but before making the investment, make sure you obtain a precise estimate or bid on the cost of installation.
- A work like this should not be attempted on your own unless you are a licensed professional in the field.
- The majority of manufacturers will not respect their warranties if a consumer attempts to do the installation on their own time.
- If you do decide to go the tankless way, keep in mind that your house, your energy expenses, and the environment will all benefit from your decision.
