What size heater do I need for a garage my 10 ft by 15-foot garage?
The simplest way to estimate the size heater you will need is to follow the rule that 10 watts will be required for every square foot of floor space. So, for your garage, multiply 10 x 15 which gives 150 then multiply this by 10 which gives 1500, meaning you need a unit that produces 1500 watts of power to heat the space.
Gas heaters are measured in BTU’s. You can estimate the required size of gas heater you will require by multiplying by the wattage by 3.41. So, for your garage, multiply 1500 x 3.41 which equals 5,115.
Of course, other factors will affect how much power you need to heat your garage. For example, spaces with high ceilings will require more heating. In addition, the amount of heat required will depend on the insulation of the building as well as if there are draughty window or doors.
