- How efficient is an electric heater? 7 answers
I can understand there being a cost difference if you used gas vs electricity to heat your home.
But for heaters using the same energy source, how can they be more or less efficient than each other?
I always thought that heat is generally a product of inefficiency. A halogen lightbulb is wasteful because for it to be bright, it radiates a lot of heat.
But I often hear the claim that cheap heaters will consume more energy. For example, this website (http://www.build.com.au/electric-heating) claims "The cheaper the electric heater, the less efficient it's likely to be”.
This is not the only place I’ve heard this. People often recommend certain types of heaters or certain brands of heaters to save on heating costs.
So if this is true, how is this inefficency caused and where is the energy lost to?
