Modulating Unitary Infrared Heater

Roberts Gordon® Vantage® Modulating Series infrared tube heater provide an energy efficient option for space heating and building comfort. Standard heater design provides adjustment of both fuel and combustion air. A modulating gas valve and variable speed blower allow the infrared heater to operate at any input between the minimum and maximum rating input. Based on heater btu/h input, performance operation ranges from 100% at maximum input, down to 66% average at minimum input.

Modulating infrared heaters have an advantage over standard single stage models or secondary two stage offering due to the standard operation flexibility. Modulating infrared heaters paired with a modulating thermostat capture the full heater input range. When the thermostat calls for heat, the infrared heater turns on at the minimum btu/h input, slowly heating the space to satisfy the room temperature. Once the temperature with the space has been satisfied, the heater modulates down maintaining the temperature but with less energy.
