Nobody wants to take a miserable cold shower, especially in the winter. So the question how long for hot water heater to refill? Is usually asked when you run out of hot water or after draining the water heater. Here is what we discovered after doing some study.
The size of the tank affects how long it takes for the water heater to fill. The filling time for an 80-gallon water tank is 30 to 40 minutes, compared to 20 to 30 minutes for a 40-gallon tank.
If you want to understand more about the typical recovery time and what to do if your water heater doesn’t fill up, keep reading.
How Long for Hot Water to Refill with Certain Types of Water Heaters?
Water can heat up quickly or take anywhere between 60 and 80 minutes. Your water heater’s kind will determine everything. Given that the appliances are brand-new and the right size for the house, the following are some typical heat-up periods for various water heaters:
- 60–80 minutes for an electric storage tank water heater.
- Water heaters with propane tanks take 30-40 minutes to heat.
- 0 minutes for propane tankless water heaters.
Keep in mind that these are the lengths of time needed to warm a fresh, filling water heater tank. When you have a storage-tank water heater, the device continuously heats and refills water for use as needed.
However, if you use up all the hot water (for example, after a busy morning of taking many showers), you’ll have to wait until your appliance replenishes from a low level. During peak hours, you can run out of hot water unless you have a propane tankless water heater that warms water instantly.
How Long For Hot Water Heater To Heat After Reset
Let’s speak about the typical recovery period for a water heater and what constitutes a “rapid” recovery. This makes it simple to see whether yours is taking a lot longer than normal.
For instance, the typical recovery period for an 80-gallon tank with entering water at 62 degrees is as follows:
- 60-70 minutes (for a gas tank water heater)
- 120 minutes (for an electric tank water heater)
You’ll observe that gas water heaters heat water considerably more quickly. Gas water heaters employ burners, which heat water more quickly than electric water heater heating coils because they reach higher temperatures more quickly.
How Long Does It Take For A 50-Gallon Water Heater To Heat Up
Water entering a 50-gallon hot water heater at 60 degrees takes approximately 1 hour and 20 minutes to heat using 5,500-watt elements set at 120 degrees. In contrast, it takes 1 hour, and 47 minutes to heat the same tank of water when the water entering it is 40 degrees. It takes the tank 1 hour, and 6 minutes to fully heat up from the 70-degree water that enters it.
The temperature that a gas water heater is set to and the temperature of the cold water that it must heat will determine how quickly it can heat up. These averages are provided:
- 40-gallon gas water heater: 30-40 minutes
- 50-gallon gas water heater: 40-50 minutes
- 80-gallon gas water heater: 60-70 minutes
The typical gas water heater has a capacity of 40 gallons and heats water from 40 degrees to 120 degrees in 30 to 40 minutes. The heating process for a 50-gallon water heater will take 40 to 50 minutes.
