Tankless water heaters are a popular option for homeowners who want to save energy and space. Unlike traditional water heaters, which store hot water in a tank, tankless water heaters heat water on demand, which can lead to significant energy savings. However, it’s important to choose the right size tankless water heater for your home to ensure that you have enough hot water when you need it.
- Determine Your Household’s Hot Water Needs
- Calculate Your Flow Rate
- Consider Your Climate
- Choose the Right Size Tankless Water Heater
Determine Your Household’s Hot Water Needs: The first step in choosing the right size tankless water heater for your home is to determine your household’s hot water needs. This will depend on the size of your household, your daily routines, and your hot water usage patterns. To get a rough estimate of your hot water needs, consider the following factors:
- Number of people in your household
- Number of bathrooms in your home
- Frequency and length of showers and baths
- Frequency of dishwashing and laundry
- Any other hot water demands in your home (e.g., filling up a hot tub)
Calculate Your Flow Rate: Once you have a rough estimate of your hot water needs, you’ll need to calculate your flow rate. This is the rate at which water flows from your fixtures and appliances, measured in gallons per minute (GPM). To calculate your flow rate, follow these steps:
- Turn on the hot water in one of your fixtures (e.g., shower, sink, or bathtub).
- Use a container to catch the water for 60 seconds.
- Measure the amount of water in the container in gallons.
- Divide the amount of water by 60 to get your flow rate in gallons per minute (GPM).
Consider Your Climate: Your climate can also impact your hot water needs. If you live in a colder climate, you may need a larger tankless water heater to ensure that you have enough hot water when the temperature drops. On the other hand, if you live in a warmer climate, you may be able to get by with a smaller tankless water heater.
Choose the Right Size Tankless Water Heater: Once you’ve determined your hot water needs, calculated your flow rate, and considered your climate, you can choose the right size tankless water heater for your home. Tankless water heaters are typically rated by their flow rate, measured in GPM. Choose a tankless water heater that has a flow rate that matches or exceeds your calculated flow rate. Keep in mind that it’s better to err on the side of a larger tankless water heater, as this will ensure that you have enough hot water when you need it.
Choosing the right size tankless water heater for your home is an important decision that can impact your energy usage and comfort. By following these steps, you can ensure that you choose a tankless water heater that meets your hot water needs and provides you with years of energy-efficient hot water.
