What is Space Heater?
A space heater is a portable electrical device designed to heat a single room or small area rather than an entire building. These appliances work by converting electrical energy into heat through various methods including ceramic elements, oil-filled radiators, or infrared technology.
The primary purpose of space heaters is to provide supplemental heating in rooms where central heating is insufficient or too expensive to run. They offer targeted warmth exactly where you need it most, making them ideal for home offices, bedrooms, or drafty living spaces.
Modern space heaters come with numerous safety features including tip-over protection, overheat sensors, and cool-touch exteriors. Many models also include thermostats and programmable timers for energy efficiency and convenience.
These devices represent a cost-effective heating solution for those looking to reduce their overall energy consumption while maintaining comfort during colder months. They're particularly valuable in older properties with poor insulation or as temporary heating solutions.
Benefits of Space Heater
