The Role of Flow Rate and Temperature Rise in Sizing
When it comes to sizing a tankless electric water heater, two crucial factors must be considered: flow rate and temperature rise. These factors play a significant role in determining the appropriate size unit for your specific needs.
Flow rate refers to the amount of water the unit needs to heat at any given moment. It is measured in gallons per minute (GPM). Factors such as the number of faucets, showers, and appliances that will be running simultaneously will impact the required flow rate. By understanding your household's hot water demands, you can accurately determine the flow rate necessary for your tankless electric water heater.
Temperature rise, on the other hand, represents the difference between the incoming cold water temperature and the desired hot water temperature. It is crucial to determine the appropriate temperature rise to ensure that the water heater can effectively heat the water to the desired temperature. Factors such as the climate in your area and the temperature of the incoming cold water will influence the temperature rise.
Factors to Consider for Sizing
When sizing a tankless electric water heater based on flow rate and temperature rise, it is essential to consider the following factors:
- Hot water demand: Determine the maximum number of fixtures, showers, and appliances that will be in use simultaneously to calculate the required flow rate.
- Coldwater temperature: Measure the temperature of the incoming cold water to determine the temperature rise needed to reach the desired hot water temperature.
- Ambient temperature: Consider the climate conditions in your area, as colder climates may require a higher temperature rise.
- Peak usage times: Take into account the times of day when hot water demand is highest to ensure that the unit can meet the household's needs during these peak usage times.
By accurately calculating the required flow rate and determining the temperature rise, you can select the right size tankless electric water heater that will provide a consistent supply of hot water and meet the needs of your household.
Flow Rate (GPM) Temperature Rise (°F) Recommended Tankless Electric Water Heater Size 1-2 30-40 Small (e.g., 2-3 GPM) 2-4 30-40 Medium (e.g., 4-6 GPM) 4-6 40-50 Large (e.g., 6-8 GPM)
