How Big Of A Water Heater Do I Need?

When it’s time to replace your water heater, one of the biggest questions is, “How big of a water heater do I need?”. If you choose a unit that’s too small, you risk running out of hot water halfway through your morning shower. Pick one that’s too large, and you’ll be wasting energy and money heating water you don’t need. The right size depends on your household’s hot water usage, and at Sanks Mechanical, we’re here to help you figure it out.

Factors That Affect Water Heater Size

1. Household Size
The more people in your home, the more hot water you’ll likely use. A one-person household may only need a 30-gallon tank, while a family of five might require 50 gallons or more.
2. Simultaneous Usage
Think about how often hot water is used at the same time. Do you have multiple showers running in the morning? Running a dishwasher while doing laundry? The more overlap, the bigger the tank you’ll need, or you may want to consider a tankless option.
3. Appliance Efficiency
Modern dishwashers and washing machines often use less hot water than older models. If you’ve recently upgraded, you might get by with a slightly smaller unit than you had before.
4. Fuel Type
Gas and electric water heaters have different recovery rates, which is the speed at which they heat water. A gas water heater might require a smaller tank because it can reheat water more quickly than an electric one.

What About Tankless Water Heaters?

If space is tight or your household uses hot water more sporadically, a tankless water heater could be a great option. These systems heat water on demand, meaning they never “run out” of hot water, which is ideal for homes that want energy efficiency and endless hot showers. The sizing process is different, but our pros at Sanks Mechanical can help you calculate your needs.
