How Many People Will A 30 Gallon Gas Water Heater Service?

Smashing question.

The answer? Well, to get an accurate answer yous'd have to calculate out how much hot water you lot typically employ during your busiest "hot-h2o-using" hour.

Only if you just need a loose estimate of what size you need (versus an exact calculation), follow these guidelines:

• For one to 2 people: xxx-twoscore gallons

• For ii to 3 people: 40-50 gallons

• For 3 to iv people: l-60 gallons

• For 5+ people: lx-80 gallons

We'll explain why the numbers higher up are just "loose estimates" and how they might not accurately meet your hot water needs. We'll also show you how to calculate the exact h2o heater size that meets your needs (and saves y'all money).

Heads up: this article will focus on tank water heater sizing. If yous're interested in a tankless water heater and need sizing communication, just check out our blog on tankless water heater sizing .

Only need a loose estimate for now? First hither…

Sometimes, homeowners only want a vague idea of water heater sizing and then that they can get a better idea of how much their water heater install will toll. (Spoiler alert: the size of your water heater directly relates to its cost; the "bigger" the water heater, the higher the cost.)

In that case, you lot can judge the size you'd need based on the number of people in your household (see below).

Warning: The numbers in this chart are to exist used as very general guidelines and may not accurately match your hot water needs.

For example, a family of 5 or more could live very comfortably on a xxx-gallon tank water heater while a household of 2 might find that a 30-gallon tank tin't provide plenty hot water for their needs.

Y'all see, the size you need completely depends on your hot water using habits. If you regularly apply 3 or more hot water appliances inside the aforementioned hour, you might need a much larger tank than the chart higher up indicates. But if y'all rarely use more than one hot water appliance in the same hour, you might need a much smaller tank.

That said, before yous buy a water heater, you should be very sure that the tank size is accurate for you.

Hither's why:

• A water heater that's too small could lead to never having enough hot water and/or a water heater that'south overworked, leading to frequent repairs or premature breakdown.
• A water heater that's also big could lead to higher-than-necessary energy bills (to heat water yous don't even use).

Want to know the exact size water heater you lot need? Do this...

1. Determine which hour during a typical 24-hour interval is your busiest "hot-h2o-using-hour".

To calculate the exact water heater size your household needs, you need to first calculate your "peak hr demand".

Peak hour demand refers to the maximum corporeality of hot water you need (measured in gallons) during the busiest hour of your typical day.

Proceed in mind that showers typically use the most hot water of all hot water activities/appliances. That being said, if everyone in your household typically showers in the morning your "peak hour" is most likely during this fourth dimension.

2. Apply the chart below to add together up the gallons of hot h2o you need during this hr.

Once y'all've determined which hour is your tiptop 60 minutes, remember of all the hot water activities you lot would usually fit into that specific hour.

And then, use the chart below to summate your approximate summit hour need:

3. Find a water heater that has a "first hour rating" within one-2 gallons of your acme 60 minutes demand.

All water heaters have an FHR (outset hour rating). This number signifies the number of gallons of hot water the unit can provide in a single hour, starting with a full tank of hot water.

So, basically, if your FHR and peak hour demand match, your water heater will encounter your hot h2o needs.

If you're on a manufacturer's site, you can find a water heater's FHR either under the "specifications", "features" or "performance" section (see below).

If yous're looking on the water heater tank itself, y'all can find the FHR listed in the top left corner of the EnergyGuide label. Information technology will be listed as the "Capacity (first hour rating)".
