Selecting Heaters:

Use the calculator below for selecting the quantity and wattage of baseboard heaters you will need in a given area, when using the heaters as a primary heat source (no other heaters present.) Supplementing existing heaters such as a forced air furnace system requires less wattage. A general rule of thumb for primary heating is to use 10 Watts / Square Foot of heat. Example: a 10'x10' room is 100 square feet: (100 x 10 W/Ft2 = 1000 Watts.)

Result:

Keep in mind that this is for an insulated building or room insulated to "electric heating" standards and is an estimation based on average conditions.
