Are Tankless Water Heaters Better Than Traditional Water Heaters?

Tankless water heaters are designed to only heat the water you need when you need it. This means you use less energy since you are not constantly reheating the same water. When you turn on the hot water tap the water heater will recognize the command and heat the water as it is sent to you, when you shut the tap off the water heater shuts down and waits until it is needed again.

A tankless hot water heater uses much less energy than a gas water heater or electric water heater and will deliver more hot water on a constant basis. If you have ever been in the shower and ran out of hot water then you know the importance of having a larger source of hot water coming through your tap. Gas water heaters and electric water heaters store a certain amount of water in their tanks and work to keep it hot so it will be ready when you need it. The downside to this method is the excessive use of energy it takes to constantly reheat the water while waiting for it to be needed and of course the limited amount of hot water that is available to you at one time.

A tankless water heater will offer you an endless supply of hot water and never leave you shivering under an ice cold shower faucet.

Energy Costs

The savings that a tankless water heater can offer to you energy bill are dramatic. Most home owners experience a drop in their energy bills by about 40% compared to an electric water heater. Gas water heaters are much more efficient than electric so the savings are slightly lower when compared next to them.

Life Expectancy

Your typical tank style hot water heater has a life expectancy of around 10 years. A tankless water heater system will last up to 20 years, that’s twice as long as your typical tank style heaters.


The space in your home is valuable and every square inch counts. With typical gas and electric water heaters the tank can take up to 16 square feet of your homes space. The tankless water heating system is no larger than a briefcase and can be installed inside or outside of your home on any wall.

Clean Water

With your typical tank style water heaters you can expect that over time rust and other build up will occur inside the tank. This build up is transferred to your pipes and then to you through the tap in your home. Tankless water heaters deliver clean and fresh water upon demand.

You may pay more for a tankless water heating system initially but overall it is designed to save you money as well as offer an environmentally safe way to heat the water in your home.
