How do I calculate what size heater I need for my garage?
You can calculate the ideal garage heater for your garage using the formula of size (in cubic feet) times 0.133 times the desired temperature rise. These factors vary, but we generally recommend an 8,000 – 12,000 BTU garage heater for a one car garage.
How many BTUs do I need for my garage?
Roughly the formula comes out to this: (Insulation * Cubic Feet of Garage * Temperature Rise) / 1.6 = # of BTU. In an area of 3,840 cubic feet, with a 35 degree temperature rise with average insulation (or 1) would come out to this: (1 * 3840 * 35) / 1.6 = 84,000 BTU.

What size BTU heater do I need?
To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.
What size radiant heater do I need?
As a rule of thumb, you’ll need roughly 10 watts of heating power for every square foot of floor area in the room. This means that a 1,500-watt heater can be the primary heat source for an area measuring up to 150 square feet.
