Consumers can purchase ProCom vent-free heaters from more than 20 retail stores, chains and online venues, including Lowe's, Sutherlands, Orscheln Farm & Home, Grainger and Menards. ProCom manufactures four basic models of vent-free heaters, including infrared, blue flame, ice house and garage heaters.
Individuals are able to buy ProCom products in physical stores or on websites to be delivered to a store. As of 2015, prices typically range from $200 to $400 for most residential models.
Infrared heaters work with natural gas or liquid propane gas and work to heat objects in the room first. Blue flame heaters run on both types of fuel and heat the air. Ice house heaters work outdoors with propane cylinders, and garage heaters are designed for larger, more open rooms.
