As of 2015, infrared gas heaters range in price from $200 to $300, depending on the size and fuel the consumer chooses. They are available in models for natural gas and propane and have ratings from 18,000 to 30,000 British thermal units.
Infrared gas heaters produce heat in the form of infrared energy, like the sun. They can warm a person in the room almost immediately, while forced-air systems take several minutes just to warm the ducts. They are simple to install and require less maintenance than a gas furnace. The space heater allows the user to warm the areas of the home that are in use, while most forced-air systems require heating the entire building.
