The amount of BTU (British Thermal Units) required to heat a shop depends on various factors including the size of the shop, the location and climate, the type of heating system, the desired temperature, and the amount of insulation.
Generally speaking, the larger the size of the shop and the colder the climate, the more BTUs will be needed for successful heating of the shop. Single stage heating units typically require 25-30 BTUs per square foot, two stage heating units 20-25 BTUs per square foot, and zoned systems require 15-20 BTUs per square foot.
Additionally, the amount of insulation in the shop can be a factor; older, less insulated shops may require more BTUs than a newer shop with adequate insulation. For example, a 1000 square foot shop in a cold climate with a single stage furnace would require roughly 25,000-30,000 BTUs of heat.
What size heater do I need for shop?
The size of heater that you need for your shop will depend on several factors, such as the size and insulation of the shop, the prevailing temperatures in the area, and the desired temperature levels that you wish to maintain within the shop.
To determine the size heater you need, you need to first calculate the space’s cubic feet. Then, you need to calculate the R-value of the space – the measure of thermal resistance that determines the amount of resistance to heat flow through a material, such as insulation inside your shop.
Once you have the cubic feet and R-value measurements, you can then use a heat-loss calculator to determine the proper size of your shop heating system. And if you’re not comfortable with the calculations yourself, you can also hire a qualified heating technician to make sure you get the size, power and efficiency that you need.
