A British thermal unit (BTU) is a unit of measurement of the heat content of energy sources or fuels. One BTU measures closely similar to the energy emitted by lighting a match. The heat measured by a BTU is the required heat to increase 1 pound of water’s temperature by 1 degree F at the temperature in which the liquid has about 39 degrees F temperature, which is its greatest density.
So why do you need to learn about BTUs in keeping your garage heated? First of all, your garage heater does not require to heat water since it is making the wind warm. Despite this, you can still learn the heating capacity of a unit measurement through BTU. Moreover, BTU also helps in measuring how much heat an air conditioner can get rid of and comparing various heaters, which can come in handy when you need to buy one.
For your garage, use this formula in learning how much BTU is needed to keep it warm:
BTUs needed for every hour = cubic feet of space multiplied by (x) your desired temperature
Factors Affecting Your Heating Requirements
The temperature in your garage, or any part of your house for that matter, is affected by a variety of factors, which include the following:
- Space dimensions. The size of the space is crucial in determining which kind of heater is suitable for it. The bigger the space is, the bigger the unit of heater you will need.
- Weather and climate. To quickly determine the amount of BTU depending on the weather, you need to find out the BTU zone in your area.
- Type of materials used in constructing your garage
Once you’ve learned how many BTUs your garage needs to keep it warm, you can convert it to watts, and it will be easier to understand whether you need to add or remove air from the space.
