The Comfort Plus unit is designed to be the main heating system (forced air) for residential or small commercial applications. The Comfort Plus unit can be used as a stand alone furnace or can be installed with a heat pump to realize even greater efficiency and energy savings. It is a versatile appliance that can serve as a back-up for an electric furnace during on-peak times, replace a duct heater, or supplement a fossil fuel system. During of-peak hours, the Comfort Plus unit converts electricity into heat and stores that heat in specially designed, high density ceramic bricks. The Comfort Plus system has the heat storage capacity to provide total comfort 24 hours a day, while allowing the user to utilize low cost off-peak electric rates to achieve very economical and affordable heating.

The Comfort Plus unit is easy to operate. The amount of heat stored in the brick core is automatically regulated in relation to outdoor temperature and the heating requirements of the user. When the room thermostat calls for heat, heat is extracted from the unit's storage core and is distributed evenly into the home until the heat call has been satisfied.

The Comfort Plus unit has sensing devices that monitor the core, the supply and the discharge air temperatures to ensure maximum safety while providing optimum comfort. A heat pump, air conditioner, electronic air cleaner, central humidifier, programmable thermostat, etc., can easily be integrated to offer year round comfort.

The size and heating ability of the system required for an application is dependent on the heat loss of the area and the power company's off-peak hours. In addition, if the unit is not installed within the heated area, heat lost statically must be taken into account. Contact your local power company, a contractor, or Steffes Corporation for assistance in selecting an appropriately sized system.
