How Big Should My Water Heater Be?

Things to Consider When Sizing Your Home’s New Water Heater

Trying to find the right water heater for your home can be overwhelming and confusing, especially if you aren’t quite sure what to look for. However, at Casco Plumbing LLC, we enjoy making your life simpler, and we’re here to help you pick out the best water heater for your home.

Here are a few things to look for when considering the size of your home’s next water heater:

Number of people living in your home: As you can imagine, more people under one roof means higher demand for hot water. Water heaters for 1-2 people should hold at least 23 gallons, households for 2-4 people should hold at least 36, households for families of 3-5 should hold more than 46, and houses with 5 or more inhabitants should have a water heater that holds more than 56 gallons.

Energy consumption: Tankless water heaters tend to be more eco-friendly and can cut down your home’s overall energy consumption by up to 30%. They are also smaller and can be suspended on a wall, which may be more suitable for smaller homes. However, these may not be able to meet the hot-water demands of households which are inhabited full-time by more than 1 – 2 people.

Solar heating: Solar water heaters require very specific sizing in order to meet the demands of a multi-person home. First of all, you must consider the collector area, which is calculated by starting with 20 square feet each for 2 household members and an additional 8 square feet per additional inhabitant. You will also need to factor in how much solar storage your home will need in order to meet the demand for hot water during less-sunny months.

Gallons per minute (GPM): Calculate your home’s average water use by adding up your home’s gallons per minute, which can be determined by counting up your bathroom faucets (1.5 max. GPM), kitchen faucets (7.0 max. GPM), showers (2.0 max. GPM), dishwashers (2.5 max. GPM), and washing machines (3.0 max. GPM). Once you figure out how much water you and your household may need at any given time, you can determine how large or small your water heater tank should be.
