What Size Tankless Water Heater Do I Need?

Make the Right Choice For Your Home

Are you tired of running out of hot water in the middle of your shower or during the laundry? It might be time to consider upgrading to a tankless water heater. These modern marvels provide endless hot water on demand, but the key is finding the right size for your home. In this guide, we’ll help you answer the burning question: What size tankless water heater do I need?

Understanding Your Hot Water Needs

The first step in determining the right size tankless water heater is understanding your household’s hot water demands. Consider the number of bathrooms, appliances, and fixtures that use hot water simultaneously. Larger households with multiple bathrooms and high hot water usage may require a higher capacity unit.

Calculate the Flow Rate

Tankless water heaters are rated by their flow rate, measured in gallons per minute (GPM). To find the right size, calculate the peak flow rate – the maximum hot water demand in your home at any given time. Take into account simultaneous use scenarios, such as running the dishwasher while someone is showering.

Useful Rule of Thumb: 5 GPM per Fixture

A general rule of thumb is to estimate 5 GPM per fixture. This means if you have two showers, a washing machine, and a sink that may be used simultaneously, you’d need a tankless water heater with a minimum flow rate of 20 GPM.

Consider the Temperature Rise

Another factor influencing the size of your tankless water heater is the temperature rise – the difference between the incoming cold water and the desired hot water temperature. The colder the incoming water, the more energy the unit needs to heat it to your preferred temperature.

Professional Guidance Matters

Determining the right size isn’t just about crunching numbers. Seek the advice of a professional plumber to ensure accurate sizing based on your specific needs. They can also guide you in choosing an energy-efficient model that aligns with your budget and usage patterns.
