How Do Infrared Heaters Work in Crawlspaces?

A cold crawlspace can reduce the energy efficiency of your home. Homeowners often find that simply insulating their crawlspace and floors is not enough to keep the floors warm in the winter. Some homeowners opt to run ducts into the crawlspace for heating purposes or may consider using infrared heaters to keep the crawlspace warm through the cold winter months. Infrared heaters are not designed for use in crawlspaces, however, and should not be used for this purpose.
  1. Infrared Space Heaters

    • Infrared space heaters work differently than other types of heating devices because they directly heat the objects or areas they are aimed toward. They are usually used to heat small areas, such as a work space in an unfinished home or a cold craft room. These heaters use infrared radiation to heat whatever they are aimed at and, thus, do not waste as much energy as more traditional heating methods, such as radiant heat.

    Crawlspace Humidity

    • One major concern for any heating device placed in a crawlspace will be humidity and condensation. Crawlspaces typically have dirt floors, which means the air in the space will be damp throughout much of the year. Excess moisture leads to rust and electrical malfunctions, which must be accounted for when choosing a heating method.

    Crawlspace Temperature

    • Another issue to consider, when evaluating crawlspace heating options, is the temperature differential. Extremely cold temperatures mean the heaters will not only have to work that much harder to warm the area, but any duct work or air ventilation will suffer from condensation. Condensation accumulation on a warm duct in a cold crawlspace can lead to corrosion and even mold growth.

    Infrared Heaters in Crawlspaces

    • Infrared heaters are not a good fit for an area as large, cold and humid as a crawlspace. Infrared heaters are designed for heating small spaces for short periods of time. Using an infrared heater in your crawlspace can not only be inefficient in terms of energy usage but can be a potential fire hazard. The best bet for keeping a crawlspace warm is to beef up your insulation and sealing vents during the colder months.
