I can understand how a wall painted black might absorb more heat than a wall painted white.Īnd so in that sense I can understand how practically, in our real world, with real world materials, in an atmosphere under gravity, a convection heater is less effective than an infrared heater. I can understand how a convection heater might mostly heat air which heats the ceiling and not a wall 20 feet away, and Right?Īny difference in how that heat is practically "felt" in its surroundings must be due to transmission and absorption. Simplistically, if both infrared and convection heaters are 1500 watts, well, both convert 1500 watts almost perfectly into heat. I am trying to understand how that might be. Though I can imagine one type might be more effective than another type and so over the course of an hour or a day might use fewer kilowatt-hours than the other. It is winter and I am cold and trying to figure out if I should buy a space heater and what sort should I buy?Ī cheap convection heater or a "more efficient" oil heater or a "most efficient" `infrared heater.Īll are 1500 watts, so I can expect all would convert 1500 watts of A/C into heat, and. We make our world significant by the courage of our questions and by the depth of our answers.
