Rheem RTG-84XN Review

Every tankless water heater generally provides hot water on-demand, meaning it heats water temperature almost instantly anytime you need it. Besides this main function, the appliance is usually equipped with some additional features to improve ease-of-use, energy efficiency, and more. One of the most fully-featured tankless water heaters is the RTG-84XN by Rheem.

Main Features and Benefits

Besides its function as a tankless water heater, the Rheem RTG-84XN has at least 4 major additional features including energy-efficient, low minimum flow rate, digital display, and warranty coverage.

1. Energy-efficient

In terms of energy efficiency, this appliance is smartly equipped with all-copper heat exchanger. Copper is one of few materials with high thermal conductivity, meaning it has an excellent ability to conduct heat. When used for heat exchanger, copper is better than other common metals such as stainless steel and aluminum. In fact, copper has a higher thermal conductivity compared with all other metals except silver. Since heat can pass through copper very quickly, less energy is required to produce hot water.

2. Low minimum flow rate

This appliance is able to provide a maximum of 8.4 gallons of hot water per minute at 35-degree F rise or 6.7 GPM at 45-degree F rise. The good thing is that Rheem RTG-84XN only requires a minimum of 0.40 GPM activation flow rate, yet it can work well with 0.26 GPM flow rate.

3. Digital display

The ease-of-use factor is also well-built with the availability of LED display showing water temperature and error codes. The user and care manual provides a list of error codes and possible solutions to handle the related problem. An in-use indicator (lit when the appliance is turned on), power button, and temperature adjustment buttons are located near the digital display.

4. Warranty

The best thing of all is that the manufacturer offers an excellent 12-year warranty on heat exchanger, 5-year warranty on component parts, and 1-year warranty on labor. Those warranties only apply if the appliance is installed by professionals or licensed technicians.

Customer Reviews

Based on testimonials by customers, the Rheem RTG-84XN does exactly what it promises. The appliance delivers hot water instantly without consuming a large amount of energy. It is intended only for residential use for 2 to 3 bathrooms. Besides its energy-efficient aspect, this tankless water heater is as well easy to operate considering that all necessary controls including power button, temperature adjustment, digital display and light indicator are located in easy-to-reach area. Freeze protection feature is good addition that helps to improve durability aspect. Such feature prevents the unit from freezing at minus 30-degree F.

Please remember that it is an outdoor unit powered by natural gas, and the manufacturer’s warranties only apply if the unit is installed by licensed technician. The product is quite expensive, yet you may need to spend more for the installation fee. The user manual is quite lengthy which can be difficult to understand unless you are a skilled technician. This is only a minor drawback considering the excellent warranty offers attached to this product.

Where to Buy

The Rheem RTG-84XN is an impressive tankless water heater powered by natural gas. This appliance has all the necessary features for energy-efficient heating without compromising quality. It is currently available at Amazon for $929.55 or 25% less than its list price ($1,240), meaning you can save more than $310 (click here to check the recent price on Amazon). Furthermore, Amazon also offers some buying options including free shipping, one-day shipping, and more.

Rheem RTE 13 Review

The RTE 13 is an electric tankless water heater featuring space-saving design, ease-to-use temperature control, adequate water flow rate, and more. It is manufactured by Rheem, which is one of the most reputable companies manufacturing plenty of water heating solutions. Below you will find a brief review of the tankless water heater.

Main Benefits of Rheem RTE 13

1. Compact Design

Space-saving has become one of the biggest concerns in water-heating appliance industries right now. Tank water heater is always generally larger than its tankless counterpart. For this reason, some people opt for the tankless type, so they can spare some valuable spaces to store other stuffs. The RTE 13 is a tankless water heater with its overall dimension measures only at 7.5-inch L x 7.5-inch W x 7.5-inch H. Thanks for its size, this appliance can be paired with almost any appliance in the house such as kitchen sink, shower, dishwasher, and bathroom sink as well.

2. Simultaneous Hot Water Supply

The conventional tank-equipped water heater simply heats and stores hot water in the tank. Rheem RTE 13 uses a different heating mechanism that it does not need to use any type of water container at all. When turned on, it basically redirects the water to flow through heating components.

By using electric power, hot water will always be available almost instantly anytime. Even better, it will immediately stop using electric power source as soon as you turn the appliance off. Since it does not store any hot water in a container, it does not have to keep on using electric power in order to continuously maintain hot temperature. With such mechanism, hot water will always be available as you need it, yet the appliance can help to reduce your monthly electricity bills.

3. Easy Installation

The unit is ready to install as you get it out of the package. There is no need to assembly many small parts or set other cumbersome adjustments. It can be directly mounted to water pipes and used hassle-free.

Customer Reviews

In general, most customers who had purchased Rheem RTE 13 from an online store sent positive feedback. They mostly praised how easy this unit could be installed. Some reviews also indicate that the hot water will run almost instantly after the appliance is activated. This tankless water heater is able to run at maximum 4 GPM, so it can be actually connected to two different appliances such as a shower and a kitchen sink.

The product is not without its flaws. The biggest drawback is that the installation may require other components especially if you have pex or plastic water line. These components are not included in the package, so you need to purchase them separately. It uses a relatively large electric power at 240V – 13KW, it also requires additional wiring and 60amp circuit breaker. Nonetheless, it only runs when hot water is needed, so it is still more efficient appliance compared to the conventional one. Click here to read more customer reviews.

Where to Buy

Rheem RTE 13 Tankless Water Heater is available at many online stores. Amazon currently lists the product at only $179,00. For this product, the online store offers some good deals and affordable shipping rate as well. The tankless water heater is eligible for Amazon’s Free Super Saver Shipping and One-Day Shipping also.

Stiebel Eltron Tempra 24 Plus Review

Tempra 24 Plus is a tankless water heater equipped with plenty of excellent technologies including a digital display, advanced flow control, and temperature control. In general, the water heater has everything necessary to provide efficient water heating solution for a household living. It is manufactured by Stiebel Eltron, an internationally recognized company manufacturing heating appliances, hand dyers, solar applications, and more.

Advantages of Tempra 24 Plus

1. Quiet Operation and Strong Cover

Tempra 24 Plus is a proud product and part of Tempra Plus series from Stiebel Eltron. Every Tempra has been upgraded and equipped with high-grade electronic parts and a reliable cover to ensure its durability aspect. The good thing is that the unit does not have mechanical switches allowing it to operate very quietly. Furthermore, it has hinged cover that improves overall strength and safety value.

2. Digital Display/Control Panel

The front cover is attached with a digital display which acts as a control panel at the same time. You can easily adjust the desired temperature simply by setting the dial. Since Tempra 24 Plus is equipped with temperature sensor, deviation from the set point can be greatly reduced.

If you decide to change the water temperature, the unit will automatically and smoothly adjust according to your preference. A sudden change in temperature may result a discomfort, but with microprocessor technology functioning as temperature sensor, such issue can be avoided.

3. Advanced Flow Control Technology

The main function of Advanced Flow Control Technology is to ensure that the temperature is stable regardless of the demand. It is normal that such appliance has limitations in providing hot water. When the demand for hot water is very high, it usually results in temperature fluctuations.

To accommodate this issue, Tempra 24 Plus will adjust the flow of water in order to maintain the temperature. When the demand is high, the flow rate is probably reduced, but the temperature remains stable.

Customer Reviews

Plenty of people who had purchased the product stated almost the same thing. They mainly suggested that their Stiebel Eltron Tempra 24 Plus units were very easy to install. Of course, if you need to install the unit, there are some additional components to purchase such as gauge wires, 60-AMP fuses, and probably some connectors.

Logically, there must be additional cost, but it should be worth the value. In terms of function, Tempra 24 Plus generally does what it promises. It delivers hot water almost instantly as it is turned on and the temperature is fairly stable. The digital display is easy to notice as well.

The major concern is that the temperature is not stable all the time. There is a fluctuation, but it is considered normal (if not minimal). Another disappointment is that the flow of water can be slightly reduced when the unit is used for two appliances at the same time. Read more customer reviews here.

Where to Buy

Stiebel Eltron Tempra 24 Plus is widely available in online markets. Currently, the best price available is at Amazon with $749.00. The price has been 18% reduced from the original list price $915 (click here to check the latest price).

Rinnai RL94iN Review

Tankless water heaters have become more popular nowadays as the demands for efficient home appliances are also increasing. Various brands manufactured by many different companies are competing greatly in the market. Currently, one of the best products available is the Rinnai RL94iN which brings a good range of features including ease-of-use, quiet operation, and reliable efficiency rate.

Advantages

1. Maximum Capacity of 9.4 Gallons per Minute

The maximum volume possibly delivered is 9.4 gallons per minute. With such specification, Rinnai RL94iN should be adequate even when installed for multiple plumbing appliances. This water heater is indeed built to serve either residential or commercial need. Even better, the digital control allows you to set a different temperature for a different plumbing appliance. For example, you can have maximum heat for dishwasher, while you can set minimum heat for shower/bathroom at the same time.

The appliance’s range of temperature starts from 98-degree F to 140 degree F. It can actually reach 185 degree F, but this will require an additional Commercial Controller that must be purchased separately. With a maximum capacity of producing 9.4 gallons per minute, it should be able to easily supply continuous hot water for your everyday activities.

2. Natural Gas

There are two types of tankless water heater based on power source, which are electric and gas. Rinnai RL94iN is powered by natural gas, so it does not contribute to your electricity bill.

The manufacturer actually provides two different variants of this tankless water heater. This appliance is available in natural gas type and liquid propane type. You should know that each product uses different power source, so it is good to check the available fuel source at your home before you decide to place an order.

3. A 12-Year Warranty

The company offers a 12-year warranty ensuring the overall quality and durability of the product. In almost all cases, tankless water heater is indeed more durable compared to its tank-equipped counterpart. Although the price for a tankless water heater is usually high, it can be an excellent investment in the long run.

Customer Reviews

Based on customer reviews, Rinnai RL94iN is very easy to install. As mentioned earlier, each product is powered by either Natural Gas or Liquid Propane, so it is recommended that you hire professional plumber to do the entire installation procedures. The good thing is that all valves and other parts are included in the package. You will not need to purchase any additional accessory separately.

Rinnai RL94iN produces noise, but the expected loudness is normal and acceptable. In fact, the noise is the same with a bathroom exhaust fan. It operates fairly quietly, yet it does what it promises. The capacity, reliability, and efficiency simply outweigh the sounds it produces.

The only possible drawback is the flow rate. Of course, it is greatly affected by the length of pipe of your plumbing system. If the water needs to travel further, there will be a decrease in the flow rate. However, in optimum circumstance, Rinnai RL94iN works to its full potential. Click here for more customer reviews.

Where Can You Buy Rinnai RL94iN?

Ecosmart ECO 27 Review

A tankless water heater promises electric efficiency yet it delivers a constant flow of hot water for all your needs anytime necessary. A good example is the ECO 27 manufactured by Ecosmart. The appliance has almost everything necessary to reduce your monthly electric bill, but it can supply a good amount of hot water every time you need it.

Main Product Features

1. User friendly

The main point to consider in all types of appliances is user-friendly aspect. Ease-of-use has always been a major selling point of all electronic products including tankless water heater. The ECO 27 by Ecosmart is electrically powered thus the installation procedure is easier compared to other similar appliances powered by gas such as Rinnai RL94iN. Anyone with a decent knowledge of electricity and plumbing should be able to install ECO 27 properly, although professional’s installation assistance is recommended.

2. Self-Modulating

Another major benefit of Ecosmart ECO 27 is its self-modulating technology. The appliance automatically adjusts the amount of power required to heat the water. With this technology, cost efficiency reaches up to 99.8% which will generate a good deal saving for your electric bill.

3. Lifetime Warranty

There is a digital display located above the knob indicating the exact temperature you have set. Once you get used to how the setting works, you can set the appliance to deliver the desired temperature and it will even maintain the temperature without fluctuating.

Customer Reviews

Most customers did not experience any major difficulties during installation procedures. Some parts such as wires, hoses, and 40amp breakers are not included in the box, so you will need to purchase them separately. A user claims that she has been using the appliance for more than a year, but ECO 27 is still as good as new.

The ECO 27 can deliver constant supply of hot water for multiple uses at the same time including bathtub, dishwasher, washing machine, and shower. The best thing is that the temperature is still relatively hot even when those appliances are used together.

The ECO 27 seems to be perfect, but it still has some drawbacks. The only major downside is that the water temperature may fluctuate at initial use. After some seconds, however, the temperature is always steady. Another drawback is that the additional components required for installation require you to spend some amount of money as well. A 200-amperage and three 40amp double-pole breakers probably cost around 300 dollars. Read here for more customer reviews.

Where Can You Buy the Product?

Ecosmart ECO 27 is available in online stores and its official website. You should also be able to find it in department stores. Currently, Amazon has reduced the list price ($569) and it is available for only $497.23 (check the price here).

It is an electric tankless water heater designed specifically for indoor installation.

Main Features and Benefits

There are many reasons why this PowerStar water heater is superior to other similar products in the market. Some of its best features are listed as follows.

1. Efficiency of time and space

The overall dimension of this Bosch PowerStar measures at 14.8-inch x 7.3-inch x 3.4-inch, and it weighs only 5 pounds. As this electric water heater is designed for indoor installation, it should not be difficult to find an available space in home for perfect fit.

Without long pipe, it delivers hot water almost instantly anytime necessary.

2. Power Selector

Bosch AE-7.2 PowerStar provides two different power settings including high and low. At low setting, this appliance will work only with half power, but it will work to its full potential at high setting. There are two heating elements equipped inside the water heater. High setting uses both elements, while low setting only uses one of them.

3. Thermal Cut-Out

EZ 101 Review

The EZ 101 tankless water heater is a versatile appliance powered by propane gas, which can provide a maximum of 1.6 GPM. It has almost all good features necessary such as automatic on/off operation, safety timer, low water pressure ignition, battery-powered ignition, and more.

Features and Benefits

This is an outdoor unit, but it has a simple design allowing for easy installation. It is also possible to semi-permanently install this water heater, making it a very useful appliance even at camp sites, cabin, or anywhere else where electricity is not available.

1. Battery-powered Ignition

One of strongest points of EZ 101 tankless water heater is that it features battery-powered ignition mechanism. It does not need to be connected to electricity plug, so it is easier to install the unit anywhere outside the house. The ignition is powered by 2 D-cells battery. According to the manufacturer, the batteries can last for up to a year before replacement.

2. Automatic Operation

Once the water heater is properly installed, it operates automatically. It means user will not need to go outside to manually ignite the unit. If any connected shower or water spigot is turned on, EZ 101 will automatically start working. As soon as the tap is switched off, the water heater will also stop immediately.

3. Low Water Pressure Ignition

The low water pressure ignition feature allows the unit to work as usual even when there is only limited input of cold water pressure. Therefore, EZ 101 can still work to its full potential even if user connects the unit to an old or low power pumping system. This is why EZ 101 is an excellent choice for camp sites and other outdoor activities.

4. Safety Features

There are at least two important safety features equipped in the unit. First, EZ 101 will automatically turn off the gas valve anytime the water supply is interrupted. It ensures that there is no unused gas wasted. There is also 20-minute timer which can greatly reduce the risk of carbon monoxide poisoning. Both features actually emphasize on energy-saving as well.

Customer Reviews

Based on numerous customer reviews, the EZ 101 tankless water heater is generally good. Most customers suggest that this appliance functions very well and they are satisfied with how this appliance works. The automatic system is one of the best features, allowing user to remotely turn on/off the unit by simply operating the water spigot or tap. Moreover, the safety features equipped in this unit help to avoid inefficient gas use. EZ 101 is also easy to install and use.

However, there are still some drawbacks found. The biggest drawback is that the manufacturer’s warranty does not cover freeze damage. Installing the unit permanently at outdoor area may cause freezing, especially during low temperature times. People who live in cold climate will often need to drain or remove the unit to a warmer place. Users may also find that it can only deliver a maximum of 1.6 GPM thus it takes times to fill a large tub with hot water.

Where to Buy

The EZ tankless official website currently states that this item is in pre sale, but it will start shipping in few more days. However, you can try to check at Amazon to see if the product is in stock at the moment. EZ 101 tankless water heater is available for $164.95. Amazon also offers free-shipping buying option.

Navien NR-210A Review

Since the first tankless water heater reached the market, such appliance has been growing in terms of popularity and technology. One of the most technologically advanced water heaters is the Navien NR-210A which uses a new water heating mechanism called condensing technology. Some important highlights of the product are briefly outlined as follows.

Features and Benefits

In almost all cases, condensing water heater is more efficient compared to its non-condensing counterparts. The non-condensing type uses hot gases to directly heat the water. Fuel is burned and the resulted energy heats the water, but not the entire energy is used.

On the other hand, the Navien NR-210A is able to create condensation inside the main unit, ensuring that it uses only the necessary energy to provide hot water; therefore, the condensing mechanism works more efficiently. In fact, this Navien has 98% of thermal efficiency, meaning almost no gas is wasted.

The Navien NR-210A is powered by natural gas and can be installed at either indoor or outdoor area. The unit’s overall dimension measures at 17-inch W × 28-inch H × 15-inch D; it weighs around 85 pounds. Once the appliance is turned on, it can deliver hot water at a minimum flow rate of 4.6 GPM (at 77-degree F rise) and a maximum flow rate of 10 GPM (at 35-degree F rise).

Since the condensation is collected inside the unit, heat exchanger should be made of high quality material to prevent corrosion. The Navien NR-210A uses dual stainless steel heat exchangers, which are generally more resistance to corrosion compared to copper. Condensation also allows for lower exhaust temperature, so that you can use inexpensive venting materials. Air and gas pressure sensors are equipped ensuring efficient combustion, while the dual micro processors keep the hot water temperature steady. There is also a leak detector that helps you to prevent damages to the unit or other items located around it.

Costumer Reviews

There are at least 4 things praised by the customers including efficiency, design, inexpensive venting, and warranty. As mentioned earlier, condensing technology uses energy more efficiently thus it reduces gas usage. It also features space-saving design and it can be installed at either outdoor or indoor which can be perfect for a small house. Furthermore, lower exhaust temperature does not require expensive venting materials which may increase the total price you need to pay to get the appliance ready. The manufacturer offers 15-year warranty on heat exchanger, 5-year warranty on parts and components, and 1-year on labor.

The condensing technology apparently brings both benefit and disadvantage. It is indeed more efficient, but some technicians still do not understand how it actually works. A mistake in the installation procedure can greatly affect the durability aspect of the appliance, so you should only hire a professional technician who really understands how the Navien NR210A condensing tankless water heater works. Read here for more customer reviews.

Where to Buy

The Navien NR-210A is generally a cost-saving tankless water heater featuring new technology to reduce gas usage and maintain steady hot water temperature. This appliance is currently available at Amazon for $1,798.71 or 15% less than the original list price ($2,125). This item is also eligible for free shipping as well as one-day shipping options from Amazon. Fore more details, check it out on Amazon.

Eemax SP3512The heating element will transfer heat directly to the water and it shuts down instantly after you are done using it. The cooling process is as well very quick, meaning there is only minimal overshoot to prevent inefficient use of energy.

According to the manufacturer, the Eemax SP3512 works best when used for hand wash sink in a shopping mall, commercial building, school, stadium, modular office, and other public facilities. It is also compatible with sensor, metering, and hands-free faucets. The flow of water will activate the heater so there is no standby heat loss. It requires 0.3 GPM to start the appliance, and the temperature rise at 0.5 GPM is 48-degree F.

Furthermore, the SP3512 is also lead-free certified. This tankless water heater is made in USA and the company offers 1 year warranty for cartridge element and 5-year warranty against failure due to leaks caused by element assembly or heater body.

Customer Reviews

Based on customer reviews, the best feature of Eemax SP3512 is its compact design, which actually plays a major role in the installation procedure as well. A small appliance fits perfectly in tight space under a sink and it reduces the hassle of installing long pipeline. It is worth mentioning that the appliance has received approvals from many reputable organizations concerning its reliability and health factor. The warranty offered by the manufacturer is also excellent selling-point for such appliance.

On the downside, the Eemax SP3512 doesn’t bring considerable amount of power as it is mainly intended as a tankless water heater for hand wash sink. The hot water produced is not too hot as well.

This small appliance will not be able to deliver enough continuous hot water, but when it is used as the manufacturer suggested, the Eemax SP3512 can be an excellent choice.

Where to Buy

The Eemax SP3512 is generally good water heater as long as it is used as the manufacturer instructed. You will get full features when you use it for hand wash sink. You can purchase this appliance from both offline and online stores. It is currently available at Amazon for $218.60 or 39% less than the original list price ($359.93), meaning you save $141.33. Amazon also offers some buying options including free shipping, free two-day shipping, one-day shipping, and more. Click here to buy the Eemax SP3512 on Amazon.

Rinnai RU98EN Review

A non-condensing tankless water heater is considered more efficient compared to the conventional tank-equipped type, but a condensing model is the most efficient of all, such as the Rinnai RU98EN. It is one of the most powerful water heaters from Rinnai categorized under Ultra series, featuring 0.95 energy factor, 9.8 GPM, and an easy-to-use temperature controller.

Main Features and Benefits

1. Condensing Water Heater – As mentioned earlier, the Rinnai RU98EN is a condensing tankless water heater, which is considered the most efficient model compared to others currently available. In a combustion process, fuel is burned thus it produces hot gases. In this case, hot gases are used for heating the water. With a non-condensing model, some of the hot gases are simply pushed through the vents to the outside, therefore wasted.

A condensing tankless water heater, such as the RU98EN, transfers the exhaust gases to heat the incoming water. In other words, energy optimization is much better.

2. Two Heat Exchangers – In order to operate as a condensing water heater, the Rinnai RU98EN uses two heat exchangers; one is made of steel, while another is made of copper. The stainless heat exchanger is used for recapturing the heat produced by the combustion process. The copper-made one uses pre-heated water to deliver optimum heating process above the gas burner. Cold water is already pre-heated before it flows through the primary burner, allowing for optimum heating process. According to the manufacturer, the RU98EN reaches energy factor of 0.95 for either natural or propane gas.

3. Temperature Adjustment – The Rinnai RU98EN includes a temperature controller to allow you to adjust the temperature manually as intended. The default setting only allows the temperature to go from 98 degree F to 120 degree F, but when the included controller is installed, the maximum temperature reaches up to 140 degree F. Rinnai also provides other types of compatible controllers which can be useful for commercial application where higher temperatures are necessary. The included controller can also display diagnostic codes. Possible troubleshooting methods are listed in the instruction manual.

Customer Reviews

Based on customer reviews, the Rinnai RU98EN basically does its job very well. One of the customers claimed that this tankless water heater is able to perform a good job supplying hot water simultaneously for three bathroom faucets, two showers, and one kitchen faucet. The ultra series from Rinnai is indeed designed for medium to large homes. Another good thing is that the manufacturer offers 12-year limited warranty for heat exchanger, 5-year limited warranty for parts, and 1-year warranty labor for residential installations. The RU98EN only requires a minimum water flow of 0.4 GPM or 1.5 L/minute to start.

The only noticeable drawback is that this tankless water heater can be very difficult to install without the help from professional. It is completely different from installing a tank-equipped water heater. You need to use the correct gas pipe with the correct length, diameter, etc. Moreover, improper installation will void the great warranty offers from the manufacturer. Of course, hiring a professional will cost more money also.

Where to Buy

You can purchase the Rinnai RU98EN from various online stores, but Amazon currently makes this appliance available for only $1,401.95. This price is greatly less expensive compared to the actual list price that reached $2,053.00, meaning you can save more than a thousand dollar if you purchase it from Amazon. There are also some interesting buying options such as free shipping, super saver shipping, twelve-month financing, and more.
