That big tank that is sitting in your basement or hall closet. That is a water heater. If you were not sure, it heats up the water in your home so that you can take nice, hot, warm showers and properly wash your clothes. If you live by yourself or maybe just with one more person, you probably have never run out of hot water. But, if you live with a couple of teenage daughters who all take showers in the morning. You could be in store for a very cold bathing session and a minor case of hypothermia. Just kidding.

This automatic water heater tank does all of the work for you and your family. It simply makes life easy and warm. You may have wondered, “how long does it take for water heaters to heat up?” But, let’s find out how they work.

How Do Water Heaters Heat up?

Tank water heaters have a dip tube that brings the cold water in the tank. Now, if we are talking tank water heaters that run on gas, the water is heated by a flame. The flame is located in the middle of the tank and the exhaust is pushed out on the roof of your house.

Electric Tank Water heaters are very similar but there does not need to be an exhaust venting system. There is a heating element within the tank that heats up the cold-water coming in.

How Long Does it Take Water Heaters to Heat up?

If we are talking strictly gas tank water heaters. It takes them about 30-40 minutes to heat up. Now, if we are talking strictly electric tank heaters. It takes them a little longer. You should probably expect there to be hot water ready in an hour to an hour and a half.

Does It Take Your System Too Long to Heat Up? 

If you are thinking that it takes just a little too long for your system to warm up. There is a little formula.

Hot Water Tank Size + Heat Input Rate = Available Hot Water

This really turns into, how much water your water heater can hold, how hot you are trying to heat your water to, and then that equals how fast you get your hot water. If maybe you feel that your water heater is running properly but you do not have enough hot water. Maybe you and your household have outgrown your water heater capacity.
