What size heater do I need for a 12x12 room?

The first technique is to simply figure the square footage of the space you want to heat. In warmer climates, multiply this number by 10 - 15. In more moderate climates, multiply by 20 - 30. And in cold climates multiply the square foot number by 30 - 40.

Why are space heaters only 1500W?

Government regulations limit space heater output to 1,500 watts, which is not nearly enough to heat an entire home. In general, one square foot of space requires about 10 watts of electricity to heat, which means that a space heater operating at its maximum output can heat a room no larger than 150 square feet.
