New, boxed Comfortzone heaters are sold by a wide variety of retailers, including home-improvement stores such as The Home Depot, discount stores such as Walmart and online companies such as Amazon.com. Used Comfortzone heaters are available through eBay and Amazon.com.
The company that produces Comfortzone heaters is HBC Home & Hardware Products, which was established in 1971 by Howard Berger. Comfortzone's product line includes both heaters and fans. The company produces many types of heaters, including baseboard, electric radiant, infrared, oil-filled electric and ceramic heaters. Larger models are suitable for large living rooms and dens, while more compact models fit onto a desk or counter to heat a small kitchen, bathroom or office.
Features such as digital thermostats, timers and carrying handles are available on some heater models. Larger models often come with a remote control, and some units are designed to switch between operating as a heater and a fan. Compact Comfortzone heaters are available for under $100, and many small models cost less than $30, as of February 2015. All Comfortzone heaters meet or exceed UL and ETL safety standards.
Product manuals are available on the Comfortzone website, and users can find details about what size room each individual heater is designed to heat.
