Eemax is the #1 supplier of tankless electric water heater solutions in the USA. For over 25 years we’ve offered energy efficient, on demand hot water heaters for commercial applications, residential homes, industrial and safety applications. Our green, environmentally friendly water heaters offer the largest selection in the industry.

Eemax was established in 1988 with a line of tankless heaters for commercial applications ranging in size from 0.5gpm to about 1.5gpm. The original Eemax technology was patented and quickly emerged as the most flexible technology on the market, which was a critical factor in the early stages of the development of the US market for electric tankless heaters. Eemax's first product, the 9.5 kW Flow Control, was developed in 1989 as a simple on/off device for hand-washing applications.

Throughout the 1990's Eemax expanded its market leadership position by continued expansion of its product line to address higher flow rate applications. In early 2000, Eemax responded to an emerging demand for electric tankless heaters with the introduction of a line of residential products so consumers could enjoy the benefits of tankless heating. Over the last years Eemax has established a leadership position in the residential market to complement its commercial business.

The Most Advanced Tankless Water Heating

The right product for any application

No matter what the use, Eemax has a tankless water heater that is the perfect fit for your application. A tankless water heater has no storage tank and is flow activated when there is a demand for hot water. A tank heater keeps the water hot 24 hours a day whether you use it or not. Tankless water heaters also provide unlimited hot water as there is no stored capacity to run out. Because there is no storage, the physical size of a tankless heater is much smaller allowing you to install the heater much colser to the application.


Save money and energy with Eemax water heater

Eemax’s advanced Direct Heating technology gives you hot water faster and more reliably without wasting energy. Eemax tankless water heaters provide up to 99% thermal energy efficiency. Most water heaters with tanks only have 65% efficiency, if not less.


Made for Certifications and High Standards

Eemax engineers have your safety in mind when engineering their products. 

That’s why Eemax water heaters are certified to be safe and reliable by Underwriters Laboratories and the Water Quality Association. All water heaters are Lead Free Certified, while water heaters for safety use are designed to be perfect fits for OSHA and ANSI standards.
