Hi,
Watts don't care what type of heater they are powering--and they are all the same total heat. However, radiant heaters warm what they are pointed at first--and then the heat from the warmed object radiates to the room.
....Those same watts powering a heat pump will put out almost twice the BTU's of heat than the best radiant heater.
Radiant heat is not very efficient when compared to other methods of producing heat.....
There it is! Watts versus BTU's.
In regards to 'space' heaters. Do all 1500 watt space heaters put out the same BTU's of heat? I don't think I ever saw BTU's rating on the outside box of space heaters.
I now know that on vacuum cleaners they purposely do not put the amps on the outside of the box so you can't compare them.
To convert from watts to BTUs with a radiant heater, multiply the number of watts by 3.413. 1500 watts X 3.413 equals 5119 BTU's of heat.
Some heaters give you that information and some do not.
