Hot Water Heater: How Long Does It Take to Heat, Recover & Replace Hot Water?

Your water heater’s recovery time can impact your comfort and convenience. There’s nothing more frustrating than running out of hot water and having to wait. That’s why it’s important to understand your system recovery rate and what might affect it.

In this article, Apex Pros Plumbing, Electrical, Heating, and Air explains how to calculate your water heater’s recovery rate to help you determine if you might need a replacement.

Understanding Water Heater Recovery Time

Water heater recovery rate is the time it takes for your system to heat a new supply of cold water to the set temperature after you run out of hot water. In other words, recovery time is how quickly hot water becomes available after you’ve depleted your tank.

What Affects Recovery Speed?

Many things can impact recovery speed. To determine whether your system’s speed could be improved, you may want to have a water heater inspection. Some factors in recovery speed include:

• Tank size: Larger tanks may hold more water but also take longer to reheat fully.
• Heating source: A gas water heater often recovers faster than an electric one because gas burners have higher heating capacity.
• Incoming water temperature: Cold groundwater in winter will take longer to heat than warmer water in the summer.
• Thermostat setting: Homeowners who set their water heater to a higher temperature will see increased reheating times.
• Sediment buildup: Mineral sediment can insulate the water from the burner, reducing efficiency and slowing recovery.
• Age and condition: Older water heaters will lose efficiency due to worn components, scale buildup, and failing heating elements.

How To Calculate Your Water Heater’s Recovery Rate

To calculate water heater recovery time, you’ll need to determine how many gallons of water the system can raise to 90°F in one hour. The formula is as follows:

• For gas systems: (BTU X Efficiency)/750
• For electric systems: (Watts X 3.41)/750

Comparing Tank Sizes And Output

When selecting a system for water heater installation, you’ll want to consider tank size and output. At Apex Pros, our rule of thumb is:

• 30 gallons for one to two people
• 40 gallons for two to three people
• 50 gallons for three to five people
• 75+ gallons for large families

Frequently Asked Questions

What Is A Good Recovery Rate For A Water Heater?

A “good” recovery rate will depend on each household. However, electric models often have recovery rates of 18 to 25 gallons per hour, while gas systems can range from 30 to 50+ gallons per hour.

If your system is recovering more slowly than this, there may be an issue with your water heater or plumbing.

Does Water Heater Size Affect Recovery Time?

Larger tanks store more water, which means it may take longer to reheat fully. While this may be inconvenient, larger households need larger systems to avoid constantly running out. Choosing a smaller system to achieve faster recovery rates when you have high hot water demand isn’t practical.

Why Does My Water Heater Take So Long To Reheat?

A water heater that is slow to recover could have the following problems:

• Sediment accumulation
• Failing heating elements
• Dirty burners
• Thermostat problems
• Undersized system
• Aging equipment
• Plumbing issues
