I paid attention to the materials and construction of the heater. A sturdy build usually means the heater will last longer and withstand rough use, especially if you plan to use it in a garage or workshop environment.

Noise Level

Since I sometimes needed quiet while working, I checked reviews and specifications about the noise the heater produces. Some high-BTU heaters can be noisy, so this was an important consideration for my comfort.
