Heating costs in pig production rooms can be expensive. A gas-fired infrared radiant heating system was compared to a conventional forced-air convection heater, which heats the air by the ceiling that is then moved with fans. Heat is transmitted to the surfaces with a radiant heater through radiation heat transfer and may help reduce overall costs of heating. Infrared radiant heating systems used more gas but consumed less electrical energy with a temperature that was much more uniform across the room.
