Space Heater Question – Is 1,500 watts 1,500 watts? – GreenBuildingAdvisor

We have one room in our old house that’s just best heated by a space heater the few weeks of the years it’s needed.

We had an oil filled radiator type for safety around our kids.  And I totally realize that they’re all (120v) 1,500 watts, and essentially 100% of that is released as heat.

BUT!  We were given a Vornado space heater, and I swear it works better.  But it’s still the same 1,500 watts!  Is it possible it works better because there’s a higher delta in the temp of the heat it gives off?

Or is 1,500 watts, 1,500 watts no matter how you spin it?
