Model LDAP is a packaged heating system that is easy to install, says the company. According to the manufacturer, the heating system also provides "free" heat. When heated air rises to the ceiling, fans on the unit automatically cycle on, even when the thermostat has not called for heat, to force heated air back down to the floor. The airflow volume ranges from 5,500 to 16,750 cfm. Units with multiple heater sections only require one gas connection, one exhaust vent, and one electrical connection, states the manufacturer. The unit can be mounted on the wall or ceiling.
