Description: In cold climate production locations, space heating represents a significant proportion of total energy use in a hog production barn. The use of gas-fired infrared heating system presents a possible alternative for space heating in barns. In this work, an infrared radiant heater was compared with a conventional forced-convection heater by installing them separately in two identical 100-head grow-finish rooms and operating the heaters to maintain similar thermal environments in the two rooms. The energy consumption (natural gas and electricity), animal performance (ADG and ADFI), and air quality were monitored in both rooms. Results from three completed trials showed that the room with infrared radiant heating system consumed more natural gas but less electrical energy compared to the room with forced-air convection heater. Mean air temperature was slightly higher in the room with forced-convection heater than in the room with radiant heater, but air temperature distribution at various locations within each room was similar. Generally, the relative humidity, ventilation rate, gas concentrations (NH3, H2S, CO and CO2), and pig performance were relatively similar between the rooms, indicating no significant impact of the type of heater on these parameters.
