How it Works
Electric tankless water heaters are quickly growing in popularity given their potential energy savings and ability to deliver hot water on demand. Electric tankless water heaters assist in reducing the energy consumption within your home by not having to heat water in storage tanks that goes unused. A. O. Smith electric tankless models perform with high efficiency ratings and groundbreaking designs. They serve a wide range of applications, whether it be point-of-use or whole-house. These models deliver continuous hot water when you need it and they can be easily installed in places where tank water heaters can’t go, including closets and bathrooms.
Electric tankless water heaters heat your home’s water on demand. When a hot water tap is turned on, water from your pipes enters the water heater and passes through the heat exchanger. Within the heat exchanger, there is an electric resistance coil that warms the water to the desired temperature as it travels through. When sized appropriately, a constant supply of hot water is delivered to your home with ease.
