Kero World is the brand trusted by millions since 1982. Quality materials and construction, along with a 2-year warranty, makes this heater brand a standout. The KW-24G convection style heater is a popular choice. It projects 23,000 BTU's of heat in a 360 degree radius, helping to heat a large area. Also great for those winter power outages and emergency situations as it provides both heat and light when the power is out. As with any fuel burning heater, annual maintenance is required.
