Our selection of electric water heaters are supplemental and should not be counted on as a whole house electric tankless water heaters. For whole-house applications, a unit should be able to supply hot water (120°) at a rate of at least 7.0 gallons per minute or greater – which we have available in a number of gas or propane models.

For point-of-use installation, the electric tankless water heater is a marvel of space-saving and money-saving functionality. Many models can be freestanding or wall-mounted, while others are under-sink mounted; all providing hot water on demand. When the demand is satisfied, they go dormant, saving electricity until the next time.

As a buffer to provide a “head start” for a point-of-need water heater, some models include a small holding tank as large as seven gallons. But that is a far cry from the conventional 50-gallon monster in your utility room or basement.

What used to make point-of-use water heaters impractical is the same thing that makes them desirable now – energy efficiency, which is how much energy is consumed versus how much hot water is produced. Our line of electric tankless water heaters operate at an amazing 94% to 97% AFUE (Annual Fuel Utilization Efficiency). This means that as much as 97 cents out of every dollar you spend on energy for these units actually goes to heating the water.

Installation is typically very easy, with only a waterline and grounded electrical service to connect to. The smaller units run on basic house current, while the larger capacity models require 240-volt service. Those need a 20-amp dedicated service line, according to electric codes for most states.

These models are loaded with safety and performance features to ensure proper operation. For more information, installation requirements, and procedures, you can download free PDF files for any of our models. For personal, one-on-one assistance, contact our customer service department. HVACDirect.com has over 8,000 verified customer reviews at an average rating of 4.8 out of 5 stars.
