The right size tankless water heater depends on your household’s peak hot water demand, measured in gallons per minute (GPM). A typical family of four needs a unit that can deliver 7-10 GPM to handle simultaneous showers, dishwashing, and laundry.
We calculate your needs based on the number of bathrooms, appliances, and your family’s usage patterns. For example, if you regularly run the dishwasher while someone showers, we’ll size the unit to handle that peak demand without anyone experiencing reduced flow or temperature.
Oversizing costs more upfront and wastes energy, while undersizing leaves you with inadequate hot water. Our free assessment includes proper sizing calculations to ensure you get exactly what your household needs—no more, no less.
