what are the different types of electric heaters and there uses?

Question

for heating a room or heating a object plus cost

Answer 1

There are thermoelectric, ceramic , fan forced, and oil based electric heating. They can be freestanding or mounted to a wall, They can look like a heater or a lovely gorgeous fireplace.
The best one will have 1. a thermostat that you preset to a certain temperature that you prefer, (so it doesnt go on heating up a room forever) 2) mega safety tip off features which does not apply to fireplace and wall mounted ones 3) three/or four different settings- fan only, low heat, medium heat and high heat.

The cheapest but quite ordinary looking are the portable electric heaters that you see everywhere. The most popular use for that variety is the portability, since you can take them anywhere and have instant heat. However, you must be aware of the safety features , does the heat turn off by itself if the unit gets tipped over accidentally? Is the wiring and construction approved by the accepted safety licensing bodies such as UL?
I like those pretend fireplaces , the look ranges from a small squat wooden or metal furnace to a huge wall unit. They look so real. But the cost ?- from a few hundred to quite a few thousand dollars.

Answer 2

Any type of electric heat is quite expensive, such as baseboard or a space heater. Probably the cheapest way to heat a room would be with a liquid filled radiator. Once the liquid gets hot the heating element and fan would only come on when needed.
