Understanding Hot Water Systems

After a long day, you just want to take a hot shower or soak yourself in a hot tub with amazing bath scents. It is not uncommon to want to take a hot shower only to get cold water coming out of the shower. This is why it is better to understand how hot water systems work. You will most likely ask a plumber to work on it, but it can still be helpful for you to know more about your hot water system.

Traditional Hot Water Systems

The traditional systems have collection tanks where the water is piped in, stored and then heated. If you use the hot water, the tank will become empty. If you want to have hot water constantly flowing from your shower, the tank has to be constantly heated so the temperature remains the same. Even if you are not using the hot water, and the tank has insulation, the water would eventually get cooler. Traditional hot water systems take up a lot of space because they need a tank that can supply enough hot water for a bath. You would have to wait for the tank to heat the water again if someone took a hot shower before you.

Tankless Water Heater

Unlike the traditional system, a tankless water heater does not need to continuously heat a tank full of water. Since it is tankless, the water is only heated when it is being used.

There is a water faucet that will be turned on. The water will flow in the water heater, and a sensor will detect that there is water present. There is a computer system that will turn the burner on, and water that goes through the burner will then get heated up. The water will be dispensed at the right temperature and the system will shut down when you turn off the water.


You need to choose the right kind and size of hot water system to be installed in your home and have it placed near a water outlet, such as in the laundry area, a bathroom, or the kitchen. All of the pipes have to be insulated by using a closed-cell rubber. Make sure that the plumber you hire has a license number and a certificate of compliance. You should also ask how familiar they are with hot water systems.

Now that you have an understanding of hot water systems, you can easily choose which one to have installed in your home. Knowing how it works may save you from any frustration.
