Hey i have a question about these heaters, now this might be a thick question but would a 1800w Halogen heater cost the same to run as a normal electric 1800w heater?
 
Yes. Heat is heat, you've still got to heat something up whether it's with a radiant heater or a hot air gun.
 
You've still got to heat the room up. Doesn't matter how you do it, it's still heat at the end of the day so it's still going to take x Joules of energy to heat the same room up by the same temperature difference no matter what heat source you use.

The only difference is, is how efficient it is. A lot have waste through light and other such things.


You could have two heaters that emit 1.8KW of heat, but one uses twice as much energy as the other.

yes, but 1800w is the electrical input, not the useful (heat) output.

Unlikely!, even a GLS lamp is a far better heater than it is a light source, so the idea that a heater which isn't optmised for light output would waste 50% as light is absurd!... if it did so, we would sell them as light sources ;)

Besides which, any light is going to be incident on a surface...
 
The best way of using an electric heater cheaply are the storage heater types that store energy at off peak times (night) and give it out during the day when you need it.

If you have a white meter (I think that's what they're called, no?) then yeah - otherwise it makes no difference.

I already know that I was just making a point.
