If you are a person who spends a lot of time in their garage or workshop during cold winter months then a garage heater is an essential element in your space. To find a garage heater that will best heat your desired space you must first calculate its thermal output in BTUs.

In this review, I will present to you the six best garage heaters, from least to most powerful – from 30000 BTU/hr to 80000 BTU/hr. Read their specifications and find the ideal heater for you.

Tips For Buying The Best Garage Heater

Howe Powerful Is A Heater?

The power of a heater i.e. its heat output is usually measured in BTUs – British Thermal Units, and watts (electric heaters). A general rule of thumb is the higher the BTU and watt number, the higher the power. So if you have a large area that requires heating, you should choose a heater with a high BTU number.

What Is BTU?

British Thermal Unit is a unit that is used to measure the amount of power or energy produced. It correlates to the amount of energy produced (heat) and the time it is done. Heaters that produce a lot of od BTUs per hour can heat up a large space very quickly.

How Many BTUs Is Enough?

The amount of BTUs you need depends mostly on the size of your garage or any other area that requires heating. To calculate how many BTUs are necessary, you should also consider your geographic area and insulation. If your space is well insulated, it requires less BTU/hr.

Smart Thermostats

Many heaters have a built-in thermostat for temperature regulation, which is a great feature you should look for. However, there are also smart thermostats available that monitor when you’re home or out and adjust the temperature accordingly. This is very cost-efficient and some of them can be operated from your smartphone.

Types Of Heaters

Other than their thermal output, you should also consider the type of heater you’re buying. You can choose between different fuel types: electric, propane, natural gas, and kerosene. There are also two main heating types: radiant and fan-forced.
