If your water heater is too big for your home, it will likely be less efficient than a properly sized unit. A water heater that’s too small may not be able to meet your family’s hot water needs, resulting in lukewarm showers or a long wait for hot water at the kitchen sink.
Water heater sizing depends on a number of factors, including the number of people in your household, the climate you live in and how much hot water you typically use. It’s important to consult with a plumbing professional to select the right size for your home.
