Almost every household in the United States has a water heater, but not everyone knows that there are different types of water heaters available. The two most common types are conventional and tankless water heaters. If you’re in the market for a new water heater, it’s important to understand the differences between conventional and tankless water heaters so you can make an informed decision on which one is right for your home.
What is a Conventional Storage Water Heater?
A conventional storage water heater, also known as a tank water heater, is the most common type of water heater in American homes. It consists of a large cylindrical tank that holds anywhere from 20 to 80 gallons of water. The tank is typically insulated to keep the water hot until it is needed, and a heating element or burner heats the water within the tank.
Installation Process
The installation process for a conventional storage water heater involves placing the large tank in a designated area of your home, such as a basement or utility room. Once in place, a plumber will connect the water supply and install a vent for exhaust gases. This process can be time-consuming and may require some modifications to your home’s plumbing and electrical systems.
Pros and Cons
One of the main advantages of a conventional storage water heater is its affordability. It’s also relatively easy to install and can provide hot water for multiple household tasks at once. However, these types of water heaters have a limited lifespan (typically 8-12 years) and can take up a significant amount of space in your home.
What is a Tankless Water Heater?
A tankless water heater, also known as an on-demand or instantaneous water heater, heats the water directly without the use of a storage tank. When hot water is needed, cold water flows through a heating element or heat exchanger and comes out hot from the tap. Tankless water heaters can be powered by gas or electricity.
Installation Process
The installation process for a tankless water heater is more involved than that of a conventional storage water heater. It requires mounting the unit on a wall and connecting it to your home’s plumbing and electrical systems. This may require some modifications, especially if you’re switching from a conventional water heater to a tankless one.
Pros and Cons
One of the main advantages of a tankless water heater is its energy efficiency. It only heats water as needed, which can save you money on your utility bills. They also have a longer lifespan compared to conventional storage water heaters (up to 20 years). However, they may not be able to provide hot water for multiple tasks at once and can be more expensive upfront.
Conventional and Tankless Water Heater, Which One is Right for You?
When deciding between a conventional and tankless water heater, there are a few factors to consider. If you have limited space in your home and don’t have high hot water demands, a tankless water heater may be the better option for you. However, if you’re looking for an affordable and reliable option that can handle multiple tasks at once, a conventional storage water heater may be the way to go.
