How to Purchase the Right Water Heater Size

If you’re on the hunt for a new water heater, there are many things you will need to consider before making a final purchase. However, one of the most important factors to consider is the size, or capacity of the water heater. The right size water heater will meet your hot water needs, and ensure that the unit runs more efficiently.

Water heaters are available in a variety of sizes according to how many gallons they can hold or process per day. For example, an average size household will need a much smaller water heater tank than a larger house with a hot tub. In addition to size, it’s also important to pay attention to the first-hour rating (FHR) for traditional water heaters and gallons per minute (GPM) for tankless water heaters. Here’s how to find the right size water heater for your needs.

When it comes to residential use, we use hot water for showers, laundry, dish washers, and turning on the faucet. This is why it’s important to purchase the right size water heater that can provide as much hot water as you need.

So what is the right size for your needs? The most common residential water heater sizes are 40, 50, 65, and 75 gallon tanks. If you own or rent an average-size home, you can get away with selecting a 40 or 50 gallon tank. According to ConsumerReports.com, an 80 to 85 gallon per-day tank can handle around three showers, one load of laundry, one cycle of the dishwater, and turning on the faucet about nine times.

However, larger homes require larger tanks. If you own a larger home or a home with a soaking tub, you will want to purchase a bigger water heater tank. For larger homes, we recommend a 75 or 100 gallon tank.

When it comes to sizing a tankless water heater, you will need to consider the flow rate (gallons per minute) and the temperature rise of the unit. A professional technician from Payless Water Heaters can help you calculate these numbers. They can also help you determine the size for a solar water heating system.

While it’s important to purchase the right size water heater, you can also take steps to reduce your hot water consumption to save even more energy and money in the long run. You can do this by purchasing the right type of showerheads, energy-efficient dishwaters and laundry machines, and making sure to fix any leaks or problems with your hot water heater.
