Replacing Your Old Water Heater? Consider Going Tankless!

Last updated 5 years ago

Storage tank water heaters are notoriously energy inefficient, especially older electric models. When it comes time to replace your aging unit, consider a tankless water heater from your heating contractor. These units are innovative, effective, and highly cost-effective, thanks to how they operate.


Traditional water heaters contain a large volume of water, typically around 40 gallons. They need to keep this water at a constant temperature. This means they cycle on and off constantly, using energy to heat the water whether hot water is in demand or not. For long periods of time, such as when you’re away from home or asleep, this is energy that is otherwise being wasted.


Tankless water heaters operate a little differently. These units are much smaller because they do not contain a set volume of water. Instead, they contain a high-power, high-efficiency heating element or burner that activates only when hot water is in demand. For example, if you turn on your shower and select hot water, the unit turns on. Cold water enters the unit, is near-instantly heated to a specified temperature, and sent to your shower. As soon as you turn off your shower, the water heater deactivates.


This energy-saving operation is what makes tankless units popular among homeowners looking to save money and energy. A correctly sized tankless unit can heat water for an entire home, while larger homes or multi-story homes that use lots of hot water may benefit from smaller units installed closer to demand sources, such as under sinks. These are called point-of-use tankless water heaters. Your heating contractor can help you understand which option is right for your home or design a tailored solution to suit your comfort needs.
