One issue with traditional tank-style water heaters is that you can quickly run out of hot water. When you use up all of the hot water in a traditional water heater, you will often need to wait anywhere from 30 minutes to two hours or more for the water in the tank to reheat.
Just before concluding, let's quickly address the refilling aspect. The time it will take for your hot water heater to refill depends on the water pressure of the home. But as a general rule, it will take 30-40 minutes for a 40-gallon tank to fill up (1 minute/gallon).
An average 40-gallon heater will only take about 30 to 40 minutes to provide heat water, while you can expect hot water from a larger tank (80-gallons) in approximately 60 to 70 minutes. Electric hot water tanks, on the other hand, will take a little longer.
A 50-gallon water heater tank takes about 40 minutes to become operational: 20 minutes to refill, and an additional 20 minutes to heat water.
Here are some common heat up times for different water heaters, assuming the appliances are new and properly sized for the home: Electric storage tank water heater: 60–80 minutes. Propane storage tank water heater: 30–40 minutes. Propane tankless water heater: 0 minutes.
The average gas heater takes between 30 and 40 minutes to fully heat up the water in its tank. The average electric heater takes about twice as long as the average gas heater to fully heat up the water in its tank, so you can expect it to take between an hour and an hour and 20 minutes to heat up.
You'll know when your water tank is full when the hot water tap, which you turned on earlier, runs normally without any residual air coming out.
So a 50-gallon tank would be adequate for the average family of 2–3 children. Other estimates assign slightly more water for each person, saying you'll need a 30–40-gallon tank for 1–2 people, 40–50 gallons for 3–4 people, and 60–80 gallons for 5 or more people.
When hot water is called for at a faucet or appliance, heated water is pumped out the top of the tank and through the home's hot-water supply pipes. As the water level drops in the tank, it's automatically refilled with cold water, and the whole process starts over again.
For example, on a 50 gallon electric heater, if the maximum wattage input is 4500 watts, you would multiply 4500 by . 004; result, 18 gallons per hour recovery. Then divide 18 into the rated gallon capacity (50 gallons). Result would be 2.8 -- or approximately three hours operating recovery time.
However, we can provide a rough estimate based on typical circumstances. So, under normal conditions, it would take roughly 5 to 6 minutes to fill a 40-gallon electric water heater to its full capacity.
In fact, most water heaters' heating elements will only last a few hours or even minutes without water. Operating a water heater without water leads to rapid overheating and damage to the heating element, significantly shortening its lifespan.
Typically, a water heater tank takes 30 to 40 minutes to heat up so if your water heater is still working, you can count on having more hot water come back in that amount of time as long as your system is still working adequately.
In general, plumbers cost $45 to $200 per hour, while electricians cost $50 to $100 per hour. Expect the following average price ranges for labor alone: Replacing a tank-style water heater: $150–$450. Replacing a tankless water heater: $600–$1,850.
Having some air in the hot water line is a widespread issue all around North America. People also describe this as cloudy water or bubbles in hot water. When you open hot water, water splashes everywhere, and loud noises can be heard.
When you use up all of the hot water in a traditional water heater, you will often need to wait anywhere from 30 minutes to two hours or more for the water in the tank to reheat. This is why many people opt to switch to tankless water heaters.
Open either the bleeder on the hot out line, or prop open the pressure relief valve to allow the air to be removed from the tank while your filling. All other valves attached to the tank should remain closed while filling the tank.
Overall, a typical hot water tank should take no more than 30 minutes to refill completely from empty.

For instance, a typical shower uses about 10 gallons of hot water. So, if you have a 40-gallon hot water tank, you should be able to get four average-length showers out of your hot water tank. This also depends on how much hot water you use for other things.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Most homeowners should flush their water heaters every 6 months or so, but if you have extremely hard water, you may want to do it more often. Flushing your hot water heater could be necessary as often as every few months depending on the mineral content of your local water supply.
Open each hot water faucet slowly to allow the air to vent from the Water Heater and piping. A steady flow of water from the hot water faucet(s) indicates a full Water Heater.
Water Leaking From The Bottom
If you notice water leaking from near the base of your water heater, it could be an issue with the drain valve. The drain valve is designed to empty the water tank when needed, such as during maintenance. Solution: Inspect the drain valve for corrosion and replace.
