How To Choose The Right Size Conventional Water Heater

Water heater

Especially with the approaching winter weather, the ability to turn on the tap and feel hot water is an often overlooked but incredibly important part of our daily routines. After all, nothing is worse than getting in the shower, only to find that there is no hot water left.

Choosing an appropriately sized hot water heater will not only ensure your family’s needs are met, but it is also an important element of an efficiently operating appliance. With that in mind, we realize that most homeowners aren’t sure how to choose the right size water heater. Next time you are in the market for a new conventional storage water heater or a heat pump water heater, use this handy guide to help you choose the right one.

Understanding the Water Heater’s Capacity

While tankless water heaters are different, all modern water heaters that use a tank-system come with a first-hour rating. Simply put, this is the number of gallons of hot water the system can supply within one hour when starting with a full tank. Most of the time, the first-hour rating can be found on the EnergyGuide label or in the product literature.

Understanding Your Family’s Hot Water Usage

Now that you understand the capacity of the hot water heater, it is time to understand the amount of hot water your family needs. To make sure you never have a cold shower, consider your peak hour demands, or the hour of the day when the hottest water gets used. For example, this may be in the morning when everyone in the household showers before work and the breakfast dishes are being washed.

Calculate the amount of water being used in that hour using these average gallons of hot water estimations:

  • Showers – 10 gallons per shower
  • Shaving – 2 gallons per shave
  • Dishwashing by hand or Food prep – 4 gallons for 2 total minutes of running water
  • Automatic dishwasher – 6 gallons
  • Clothing washer – 7 gallons

Remember to consider each household member who uses the hot water during the peak hour, meaning if three people shower within the hour, then 30 gallons of hot water is used.

By adding up the total gallons of hot water needed within a standard peek hour, you understand your household’s hot water needs. It’s always best to choose a hot water heater that matches this estimated usage within one or two gallons.

Great HVAC Repair company! They answered when I called this morning and in the middle of Summer had a repair person out this afternoon. Our repair guy Robert May was incredibly nice, professional, and did a great job of explaining what was wrong as he fixed it. Now our AC is working perfectly!


Just Right was able to come within a few hours- helpful when the A/C is broken and its 90 degrees. The team were really nice, courteous guys who explained everything to me and provided an estimate to sign before proceeding with the work. Our A/C was up and running within an hour at a reasonable price. Thank you!


Very responsive – called to request service on a Monday morning and repairman arrived after lunch the next day. Service was excellent. Technician was professional and knowledgeable. Every step of the repair process was explained. AC unit is now working efficiently. Recommendations were made but did not push us to purchase other services or parts. Would 100% recommend!
