Discuss the power sources of space heaters and implications this has for their use.
What will be an ideal response?
All radiant heaters and many convective heaters use electricity as their power source, but convective heaters can also be fueled by natural gas, propane, heating oil or kerosene. These fuels all consume oxygen from the room in which the heater is located. They also produce as combustion products both carbon dioxide and water vapor. Combustion type heaters should only be used in ventilated areas lest oxygen levels be depleted or carbon dioxide build up to toxic level while they are operating. A low oxygen level in a room may also cause a fueled space heater to begin producing carbon monoxide which is even more toxic. Ventilation from the outside reduces the efficiency of the heater by the influx of cold outside air, but it is still a necessary safety precaution for any heater that operates with an open flame.
