Some heaters use gas as a fuel source, while others use electricity.

Gas heaters burn natural gas or propane to produce heat, while electric heaters use electricity to heat up a heating element or a ceramic plate to produce heat.

Portable electric heaters are typically used to heat small spaces or individual rooms.

No heater should be left on overnight without proper precautions, but some types of heaters are generally considered safer than others.

Electric heaters with an automatic shut-off feature are designed to automatically turn off when they reach a certain temperature or go above it.

Electric heaters with a thermostat are designed to turn off when the desired temperature is reached and turn back on when the temperature falls below a certain level.

This can save energy compared to heaters that run continuously.

It's important to note that the energy efficiency of a heater also depends on factors like the size of the room, the insulation of the room, and the frequency of use.

Choosing an energy-efficient heater is just one step towards reducing your energy consumption and costs; it's also important to use the heater appropriately, such as by adjusting the thermostat, using it only when needed, and properly maintaining and cleaning the unit.

Heaters work by converting some form of energy, such as electricity, gas, or oil, into heat.

The heat is then transferred to the surrounding environment to raise its temperature.

The price of space heaterscan vary widely depending on the type and features of the heater.

The amount of electricity a heater uses depends on several factors, including the size of the heater, the type of heater, and how often it is used.

Modern electric heaters are designed with energy efficiency in mind and can vary in terms of their power usage.
