These residential infrared gas tube heaters are especially suited for hard-to-heat areas, such as garages, workshops, vestibules or entryways, enclosed patios, green-houses, and barns, says the company. Previously available only for industrial applications, the compact, unitized 9-ft, 3-in.-long Cold Blocker™ heaters provide the ability to heat areas previously left unheated or heated at a high cost, the company says. Available in natural and propane gas, benefits include energy efficiencies ranging up to 84.5%, says the manufacturer.
