To determine the correct heater size for your space, please use the following formula:
How large is the area being heated in cubic feet? Calculate area dimensions (Length x Width x Height) = Total Cubic Feet
What is the desired temperature increase to be gained by the heater? Calculate (Desired temperature(with Heater) - Area temperature(without heater)) = Desired Temperature Increase
Calculate the BTU's required to achieve desired temperature. Calculate ((Total Cubic Feet x .133) x Desired Temperature Increase) = BTU's Required
