How Do I Know What Size Electric Tankless Water Heater I Need?


Selecting the appropriate size electric tankless water heater for your home necessitates consideration of several factors to ensure it efficiently meets your hot water demands. A critical factor is assessing the number and types of hot water fixtures in your household, including showers, faucets, and appliances like washing machines.

Each fixture has its flow rate, measured in gallons per minute (GPM), which contributes to overall hot water consumption. By totaling the GPM of all fixtures that would be in use at the same time, you can estimate your peak hot water demand. This helps guide the choice of a tankless water heater with a suitable flow rate to meet your needs adequately.

For example, if your household has a showerhead with a flow rate of 2.5 GPM, a washing machine at 3 GPM, a dishwasher at 1.5 GPM, and a kitchen faucet at 1.5 GPM, adding these figures provides an estimate of your peak hot water demand. If you know two people are always taking a shower simultaneously and the dishwasher is often in use, you will add the flow rates of two showerheads and one dishwasher for a total of 6.5 GPM. This ensures you select a tankless water heater that can handle your household's peak demand efficiently. Additionally, electric tankless water heaters like the Eccotemp SHiE-27 offer adjustable amperage settings via the Eccotemp Smart App, providing further flexibility to adapt to changes in hot water demand over time.

Apart from assessing fixture flow rates, understanding your household's hot water usage patterns is essential when selecting an electric tankless water heater. Factors such as the number of occupants, their bathing habits, and the frequency of hot water usage throughout the day significantly impact hot water demand. By evaluating these usage patterns, you can anticipate peak demand periods and ensure that the tankless water heater you choose can comfortably meet these fluctuations. For instance, if your household typically experiences high hot water demand in the morning when multiple people are showering, washing dishes, and using other hot water fixtures simultaneously, you'll want an electric tankless water heater with a flow rate sufficient to handle this peak usage without running out of hot water. This consideration ensures that your electric tankless water heater can provide a consistent and reliable supply of hot water to meet your household's needs.

Additionally, it's essential to consider the temperature rise needed to heat the incoming cold water to your desired hot water temperature when selecting an electric tankless water heater. The temperature rise, measured in degrees Fahrenheit, is determined by the variance between the groundwater temperature and the desired hot water temperature at the faucet. In regions where groundwater temperatures are colder, a larger temperature rise is required to achieve the desired level of hot water comfort. For instance, if your groundwater temperature is 65°F and you desire a hot water temperature of 105°F, the required temperature rise would be 40°F. Understanding the temperature rise enables you to choose an electric tankless water heater with the appropriate heating capacity to meet your hot water needs effectively, ensuring a comfortable and consistent hot water supply regardless of external temperature conditions. This consideration ensures optimal performance and efficiency from your electric tankless water heater, enhancing your overall hot water experience.

For homes with moderate hot water demands ranging from 4 to 6 gallons per minute (GPM), electric tankless water heaters are ideal choices. These mid-size home tankless water heaters, such as the Eccotemp SHiE-27, offer flexibility and efficiency to meet the needs of mid-size residences, tiny homes, apartments, or townhomes. With adjustable amperage settings via the Eccotemp Smart App, users can customize the heater's output to match their specific requirements, ensuring optimal performance and energy efficiency. Additionally, features like on-demand heating and smart controls enhance convenience and reliability, making electric tankless water heaters suitable solutions for households with moderate hot water demands.

Ultimately, selecting the right electric tankless water heater involves choosing one with a flow rate that matches your household's hot water demand while also considering potential future changes. By evaluating fixture flow rates, hot water usage patterns, and temperature rise requirements, you can determine the appropriate size to ensure optimal comfort and efficiency. Additionally, features like adjustable amperage settings and smart controls, as seen in models like the Eccotemp SHiE-27, provide flexibility and convenience, allowing you to tailor the water heater's performance to your specific needs. This comprehensive approach ensures that your electric tankless water heater can reliably meet your hot water needs both now and, in the future, enhancing your overall hot water experience.

What Are the Advantages of Using a Smart Electric Hot Water Heater?


Smart water heaters offer a distinct advantage over traditional models through their enhanced energy efficiency. These advanced models are equipped with intelligent sensors and programmable settings that allow users to optimize energy usage based on their personal schedules and preferences. For instance, a smart water heater can be set to heat water during off-peak hours when electricity rates are lower, reducing overall energy costs. This leads to significant savings on utility bills and a reduced environmental footprint.

Another major benefit of smart water heaters is their remote monitoring and control capabilities. Through mobile apps or home automation systems, users can monitor and adjust their water heater's settings from anywhere. This remote access ensures that homeowners can always check the status of their water heater, receive notifications about maintenance needs, and adjust temperature settings on the go. In case of any issues, such as a potential leak or system malfunction, smart water heaters can send alerts directly to the user's smartphone, allowing for prompt action to prevent damage and costly repairs. This level of connectivity provides peace of mind and convenience that traditional water heaters cannot match.

Moreover, smart water heaters contribute to improved safety and reliability. Many models come with advanced diagnostic features that continuously monitor the system’s performance and detect potential problems before they escalate. These diagnostics can identify issues like mineral buildup, which can compromise efficiency and lead to system failure if left unchecked. By proactively addressing maintenance needs, smart water heaters can extend the lifespan of the model and ensure consistent performance.

Do Tankless Electric Water Heaters Need Regular Maintenance?


Electric tankless water heaters are an excellent option for homeowners, providing instant and unlimited hot water precisely when and where it's needed, surpassing the efficiency of traditional water heaters. To ensure these advanced systems continue operating at peak performance and maintain their efficiency over time, regular maintenance is crucial. This maintenance may include tasks such as descaling to remove mineral buildup and checking for leaks or malfunctions.

A crucial part of maintaining an electric tankless water heater is routinely cleaning its internal components to prevent sediment and mineral buildup. Minerals found in the water supply can accumulate over time, causing scale formation and reducing the water heater's efficiency in transferring heat. To address this, it's advisable to descale the electric tankless water heater at least twice annually, or more frequently in regions with hard water. Eccotemp tankless water heaters are fully compatible with the EZ-Flush System Descaling Kit. Using this kit involves flushing out the accumulated sediment and minerals using the kit’s descaling solution to restore the water heater's performance and prolong its lifespan. Regular descaling helps ensure optimal operation, prevents potential issues like reduced flow rates or system malfunctions, and extends the longevity of the electric tankless water heater.

In summary, while electric tankless water heaters provide several benefits, such as energy efficiency and instant hot water on demand, consistent maintenance is crucial for maintaining peak performance and longevity. By integrating regular cleaning and descaling into their maintenance routine, homeowners can optimize the efficiency and lifespan of their electric tankless water heaters.
