Understanding Your Options
When it comes to choosing a tankless water heater, Rheem offers both gas and electric options. Gas tankless water heaters are typically less expensive to operate but require venting, while electric tankless water heaters are easier to install and do not require venting. The choice between gas and electric depends on your specific needs and preferences.
If you only need hot water in a single location, such as a bathroom or kitchen sink, a point-of-use tankless electric water heater may be suitable. These smaller units provide hot water directly to the designated area, saving energy by eliminating the need to heat water throughout the entire home.
For whole-home applications, it is important to select a tankless water heater that matches your home's existing service. If you have natural gas available, a gas tankless water heater would be a good option. If your home is only equipped with electric service, an electric tankless water heater would be the appropriate choice. By considering your hot water needs and the available power sources in your home, you can make an informed decision on the type of tankless water heater that best fits your requirements.

Understanding your options and considering factors such as power sources, hot water needs, and installation requirements will help you choose the right tankless water heater for your home. Rheem's wide range of gas and electric tankless water heaters ensures that you can find a model that fits your specific needs and provides efficient and reliable hot water.
Calculating the Temperature Degree Rise
When determining the appropriate size for your Rheem tankless water heater, it is essential to calculate the temperature degree rise. This measurement helps determine the difference between the incoming water temperature and the desired output temperature. Rheem recommends assuming an incoming water temperature of 50°F and a desired output temperature of 105-115°F. However, please note that these temperatures can vary depending on your location and personal preferences.
To calculate the temperature degree rise, subtract the incoming water temperature from the desired output temperature. For example, if you desire a maximum output temperature of 110°F and the incoming water temperature is 50°F, the temperature degree rise would be 60°F. This calculation provides valuable insight into the capacity needed from your tankless water heater to meet your hot water demands efficiently.
By accurately calculating the temperature degree rise, you can ensure that the Rheem tankless water heater you select is appropriately sized to deliver the desired output temperature consistently. This calculation is crucial for optimizing the performance and energy efficiency of your tankless water heating system, providing you with the comfort and convenience of hot water on demand.

Determining Simultaneous Hot Water Needs
When selecting the right Rheem tankless water heater for your home, it's important to consider your simultaneous hot water needs. By determining the required flow rate, you can ensure that the tankless water heater can meet your household's demand. Rheem provides a useful sizing tool that can help you calculate the minimum gallons per minute (GPM) requirement for your specific needs.
Using the Rheem sizing tool, you can input information about the fixtures in your home and the number of devices you expect to run simultaneously. The tool takes into account various factors such as sinks, showers, and washing machines, and provides an estimate of the total GPM required. This ensures that you have enough hot water available at all times, without any interruptions.
Here's an example of a table that showcases the typical GPM for common fixtures:

By adding up the GPM for all the devices you plan to use simultaneously, you can determine the minimum GPM requirement for your tankless water heater. This will ensure that you have enough hot water to meet your household's needs, providing comfort and convenience.
Rheem Water Heater Size Guide
When choosing a Rheem tankless water heater, it is essential to consider the specifications of each model to ensure it meets your hot water needs. The Rheem website provides detailed product information for each tankless water heater, including the gallons per minute (GPM) at different temperature rises. By referring to this information, you can compare the GPM requirements of your household with the capacity of the tankless water heater.
To help you understand the sizing requirements, we have provided a comprehensive table comparing the GPM ratings of different Rheem tankless water heater models.

Tank or Tankless?
When choosing a water heater for your home, one of the big decisions you'll need to make is whether to go with a traditional tank-type heater or make the switch to a tankless system. While both options have their benefits, tankless water heaters offer several advantages that make them worth considering.
One major advantage of tankless water heaters is their energy efficiency. Unlike traditional tank-type heaters that constantly heat and store water, tankless heaters heat water on demand. This means they only use energy when hot water is needed, resulting in potential energy savings for homeowners. Additionally, tankless systems eliminate the risk of standby heat loss, which can occur with tank-type heaters.
Another benefit of tankless water heaters is their ability to provide unlimited hot water. With a properly sized tankless system, you will never run out of hot water, no matter how many fixtures are being used simultaneously. This is particularly beneficial for larger households or homes with high hot water demands. By using Rheem's tankless water heater size calculator, you can ensure that you select the right size unit to meet your specific needs.
Finally, tankless water heaters offer space-saving advantages. Traditional tank-type heaters can take up a significant amount of space, especially in smaller homes or utility closets. In contrast, tankless water heaters are compact and can be wall-mounted, freeing up valuable space in your home. This is especially important for homeowners with limited storage or living space.

- Tank water heaters are less efficient than tankless water heaters due to standby heat loss. This means that even when hot water is not being used, the tank is constantly working to maintain the set temperature, resulting in energy waste.
- Tankless water heaters provide unlimited hot water as water is heated on demand. With a properly sized unit, you will never run out of hot water, even if multiple fixtures are being used simultaneously.
- Tank water heaters require a significant amount of space due to their large tank size. In contrast, tankless water heaters are compact and can be wall-mounted, freeing up valuable space in your home.
- Tank water heaters typically have a lifespan of 10-15 years, while tankless water heaters can last 20+ years with proper maintenance. This longer lifespan can result in cost savings over time.
Overall, when considering a water heater for your home, the advantages of a tankless system, including energy efficiency, unlimited hot water supply, and space-saving design, make it a compelling option. By using Rheem's tankless water heater size calculator, you can ensure that you choose the right size unit to meet your specific needs, resulting in optimal performance and efficiency for your home.
Additional Considerations
When sizing a Rheem tankless water heater, there are several additional considerations to take into account. These factors can help ensure that the tankless water heater is properly sized to meet your specific needs.
Climate:
The climate you live in can impact the performance of your tankless water heater. In colder climates, the incoming water temperature may be lower, requiring a larger tankless water heater to achieve the desired output temperature. Conversely, in warmer climates, a smaller unit may be sufficient.
Home Size and Layout:
The size and layout of your home can influence the demand for hot water. Homes with multiple bathrooms or fixtures located far apart may require a larger tankless water heater to meet simultaneous hot water needs throughout the house.
Household Size and Usage:
The number of people in your household and their hot water usage patterns can impact the size of the tankless water heater you need. A larger household with high hot water demands may require a larger unit to ensure an adequate supply of hot water for all members.
Fixture Types:
The types of fixtures you use in your home can also affect the sizing of your tankless water heater. Certain fixtures, such as high-flow showers or deep-soaking tubs, may require a higher GPM (gallons per minute) capacity to maintain optimal water flow and temperature.
By considering these additional factors along with the Rheem tankless water heater size calculator, you can determine the perfect fit for your home. Taking the time to accurately size your tankless water heater will ensure optimal performance, energy efficiency, and a reliable supply of hot water for years to come.
