How tankless water heater sizing works
- Determine household size: The number of people in the household affects the hot water demand.
- Calculate peak usage: Estimate the maximum hot water flow rate needed during peak times.
- Measure water temperature rise: Determine the temperature difference between the incoming cold water and the desired hot water temperature.
- Select the appropriate heater: Based on flow rate and temperature rise, choose a heater that meets these requirements.
Calculating the capacity of tankless water heaters
To calculate the capacity, consider the following steps:
- Flow rate requirements: Measure the gallons per minute (GPM) needed for appliances and fixtures.
- Temperature rise: Calculate the difference between the incoming water temperature and the desired output temperature.
- Heater output: Select a tankless electric water geyser that can handle the required GPM at the necessary temperature rise.
What size tankless water heater is suitable for your household?
Choosing the right size tankless water heater for your household is crucial to ensure an efficient and consistent hot water supply. Here is how to determine the appropriate size:
1. Assess household size and water usage:
- For 1-2 people, a heater with a capacity of 3-4 GPM may suffice.
- For 3-4 people, consider a unit that delivers 5-7 GPM.
- For larger households with 5+ people, a system with a capacity of 8-10 GPM or more might be necessary.
2. Peak usage calculation:
- Identify peak hot water usage periods, such as during morning showers or evening dishwashing.
- Estimate the combined flow rate of fixtures and appliances used simultaneously. For example, a shower typically uses 2-3 GPM, a dishwasher around 1.5-2 GPM, and a washing machine about 2-2.5 GPM.
3. Temperature rise consideration:
- Determine the incoming cold water temperature, which can vary by season and region.
- Subtract this from the desired hot water temperature (usually 120°F). For instance, if the incoming water temperature is 50°F, the required temperature rise is 70°F.
4. Selecting the heater:
- Choose a tankless water heater model that meets or exceeds the calculated flow rate at the required temperature rise. Most manufacturers provide charts or calculators to help match their products to your needs.
By accurately determining your household's hot water demand and considering factors such as flow rate and temperature rise, you can select a tankless water heater that ensures an uninterrupted hot water supply, enhancing your home's comfort and efficiency.
