In choosing a baseboard heater for a room, watts is typically considered instead of BTU/Hr. If you want to convert watts to BTU/Hr, the equation is watts x 3.412=BTU/Hr

Determine Your Heating Needs

The general guideline for electric baseboard is 10 watts per square foot of space and 1.25 watts per cubic foot for fan forced heat in rooms with 8’ ceilings, rounding up to the product with the next highest wattage rating.

Square Ft. Example: 100 sq. ft x 10 watts per sq. ft. = 1000 watts total (3412 BTU/Hr). A 10’ x 10’ room would require 1000 watt baseboard.

Cubic Ft. Example: 1152 cu. ft. x 1.25 watts per cu. ft. = 1440 watts total (4913 BTU/Hr). A 12’ x 12’ room with an 8’ ceiling would require a 1500 watt fan forced heater.

The best place for installing a baseboard heater is on an outside wall under a window. This will allow the natural convective currents from the baseboard to provide a curtain of warm air against the cool wall. Thermostat placement should be on the opposite wall from the baseboard heater. Fan-Forced heaters should be placed on an inside wall with thermostat about 36�? above the heater.
