The makers of the Alpha Heater claim that this portable heater employs cutting-edge PTC Ceramic Technology to heat rooms quickly and effectively while also lowering customers' energy expenditures. The energy-saving feature is there to help you save money, but the value of the safety feature cannot be stressed given that portable space heaters are a major cause of house fires and present obvious concerns. Its energy-saving feature and its auto shut down safety feature are possibly the two most crucial features. According to the specifications, it has a wattage between 650 and 1200, which is less than the wattage of the majority of commercial space heaters.
