Reduce energy expenses with a highly efficient tankless water heater

Learn about the difference a high-efficiency water heater can make in your home.

Many homeowners have outdated tank-type water heaters that don't provide the efficiency they want in their home. A tankless water heater, also called an on-demand water heater, only begins to heat water when a demand is made by opening a hot water tap, turning on a dishwasher, or operating a washing machine. This makes it a highly efficient system that can save you money.

How a tankless water heater works

Compact and efficient: A tankless water heater can be mounted just about anywhere - even in the attic, as shown in the photo.

Traditional water heaters require a large tank to hold water that is heated and distributed as necessary. As you'd expect, tankless water heaters eliminate the tank because the water is heated on the way to its destination. The flow of water triggers gas burners or an electric heating element inside the heating unit.

When the tap is closed, the heat goes off and energy consumption stops. Because a tankless water heater eliminates standby heat loss, you're not paying to continually reheat water in a tank. This makes any tankless water heater inherently more efficient than any tank-type water heater. Case studies have demonstrated that replacing an old tank-type water heater with a tankless model can cut water heating expenses by as much as 45%. Tankless heaters fueled by natural gas and propane are more efficient than electric models.

  • Energy efficiency: A tankless model cuts water heating expenses by as much as 45%.
  • Endless hot water: This system maintains the flow of hot water as long as the tap is open.
  • Compact size: A tankless model's small size provides many installation options for your home.
  • Long-lasting: Tankless water heaters typically last longer than tank-type water heaters.
  • No standby heat loss: There isn't any standby heat loss from a tank of hot water sitting all the time.
  • On-demand: When you're sleeping, at work, or on vacation: it's completely off. It's only on when you need it to be on.


  • Cost: Tankless models are more expensive than most tank-type water heaters.
  • Well water transfer: If you have well water with lots of minerals in it, a tankless water heater is not the best choice.
