How to Calculate the Degree Rise for Your Tankless Water Heater
When selecting a tankless water heater for your home, it's important to calculate the temperature degree rise to ensure that the chosen unit can meet your hot water needs. The temperature degree rise is the difference between the inlet temperature of the water and the desired set temperature. This calculation helps determine the capacity and efficiency required from the tankless water heater to provide a continuous supply of hot water.
In order to calculate the temperature degree rise, you will need to know the inlet temperature of the water coming into your home and the desired set temperature for hot water. The inlet temperature can vary depending on your location and the time of year, so it's best to consult your local water utility or use an average temperature for your area.
Once you have the inlet temperature and desired set temperature, subtract the inlet temperature from the set temperature to get the temperature degree rise. For example, if the inlet temperature is 50°F and the desired set temperature is 120°F, the temperature degree rise would be 70°F. This calculation will help you determine the appropriate size and capacity of the tankless water heater needed to meet your hot water demands.
Inlet temperature: 50°F
Desired set temperature: 120°F
Temperature degree rise: 120°F - 50°F = 70°F
By calculating the temperature degree rise, you can ensure that your tankless water heater is properly sized and capable of providing hot water at the desired set temperature. It's important to note that the temperature degree rise may vary based on factors such as the number of fixtures or appliances using hot water simultaneously. Consulting with a licensed contractor can help you determine the specific requirements for your household and select the most suitable tankless water heater.
Simultaneous Hot Water Needs and Gallons Per Minute (GPM)
When determining the right tankless water heater for your home, it's essential to consider your simultaneous hot water needs. Simultaneous hot water refers to the number of fixtures and appliances that will be used simultaneously, requiring hot water.
To ensure an adequate supply of hot water, you need to calculate the gallons per minute (GPM) required for your household. GPM represents the flow rate of hot water needed to meet your simultaneous hot water needs.
Here's a simple example to illustrate the concept. Let's say you have a showerhead with a flow rate of 2.5 GPM and a kitchen sink with a flow rate of 1.5 GPM. If both are being used at the same time, you would need a tankless water heater with a minimum GPM of 4 to provide hot water to both fixtures simultaneously.
Fixture/Appliance Flow Rate (GPM) Showerhead 2.5 Kitchen Sink 1.5 Total4
Calculating the simultaneous hot water needs and GPM for your household helps determine the appropriate tankless water heater capacity. It ensures that you have enough hot water to meet your demands during peak usage times.
Keep in mind that the number and flow rate of fixtures and appliances may vary for each household. It's recommended to evaluate your specific needs and consult a licensed contractor to ensure you select a tankless water heater with the appropriate GPM rating.
