Heat-flo’s Electric Water Heaters range in sizes from 10 to 119 gallons with a variety of element wattages and voltages. Models are EC and SSL/SSN. All models are sold with standard element configurations, but models SSL/SSN are field-convertible by a qualified electrician or technician. Heat-flo offers more than 50 conversion kits to fit any application. This allows a contractor to customize the Water Heater to suit the specs and requirements of the install site and property owner. All units are supplied with ¾-inch dielectric unions with 4-inch copper stubs pre-assembled for an easy “Press & Go” installation.
