NOTE: Ratings shown are at 240V/208V. 277V units are also available (charging circuits only).
*The size and heating capability of the system required for an installation is dependent on the heat loss of the area and the power company's off-peak hours. Contact your local power company, a contractor or Steffes corporation for assistance in determining the appropriate model for your application. The Maximum Maintainable Heat Loss figures listed have a heat use allowance factored in for sizing purposes. Average BTU delivery rate is the listed value multiplied by a .78 heat use factor. A static dissipation factor must also be allowed when sizing if heating system and piping are not located within the intended area to be heated.
**The weight of the heating unit must be considered when selecting an installation surface. Contact a building contractor or an architect if there are structural weight concerns.
NOTE: The Comfort Plus Hydronic unit will radiate heat at varying levels depending on core charge. If the unit is installed into an area where minimal heat is desired (i.e a small room, unheated basement, etc.) it is recommended the optional static heat recovery unit be installed with the unit. If the optional air handler is installed, it will serve as the static heat recovery device.
