Infrared heat is similar to the radio waves the sun gives off to heat a person’s body when they are outside on a clear day. When a cloud covers the sun, it feels ten degrees cooler even though the air temperature has not changed. The SUNHEAT™ infrared heater similarly uses radio waves to heat its internal copper element, and a fan blows air over the hot copper to redistribute the heat. Fragile, premature babies are kept warm using infrared heat, so you can be sure it’s safe for you and your family.
