There are many types of space heaters, but they all work by converting energy into heat and then moving that heat to the air in a room, and the most common type of space heater, which is found in various homes and small offices, is an electric radiant heater.
These gas heating systems have a heating element that emits infrared radiation to warm the room! When this radiation hits objects in the room, it causes them to warm up, but another type of electric space heating system is a convection heater, which is one of the more common types of heating systems as it is usually a bit lower in price. These heating systems have heating elements that warm up the air around them. The warm air then rises and circulates around the room, causing objects and people in the room to feel warm. Some space heating systems also have fans that help to circulate the air, which can require a bit more repair as the fans properly get covered in dust over time and need to be cleaned. Oil-filled radiant gas heating systems are another type of space heating system which are also quite common in homes. These gas heating systems have a coil filled with oil that is heated by an electric element. The oil then transfers heat to the metal coils around it, which in turn convey heat to the air, and geothermal heat pumps are a type of heater that uses the ground as a source of heating and cooling for a home. These systems are entirely efficient and can save homeowners money on their energy bills. Take your best pick and good luck!
