DCA EDHS series duct heaters will provide additional or can be a primary source of room space heating. EDHS series duct heaters are for mounting downstream from the discharge of the dehumidifier only. They are shipped loose for field installation. A single high voltage source separate from the dehumidifier and a single low voltage connection are all this is required - allowing for easy installation. Standard with every heater are air flow switches, high limit controls and fuse blocks. The optional two-stage room thermostat ties in with the 24 volt circuitry of any DCA dehumidifier. DCA also offers a complete line of gas fired duct in-line duct furnaces when desired.
