Best Natural Gas Garage Heater Buying Guide

Before choosing the best natural gas garage heater you should consider following options:

1. Fuel type: There are two main types of fuel that you might use—natural gas and propane. If you have gas available, this is the most convenient option.

Gas powered heaters are available in either a pipe coil or radiant style.

A pipe coil is the most efficient and economical option. The gas flows through pipes inside the cabinet of the heater, delivering heat to the surrounding area. The pipe coil is the most affordable option and is therefore the best choice for businesses.

A radiant gas heater works differently. Gas flows through a series of burners in the back of the cabinet, which produces radiant heat. Radiant heaters are more expensive to run and are not as energy efficient as pipe coils. However, they are more suitable for garages that contain high moisture levels, such as a workshop or bathroom.

You can also choose between electric and gas powered heaters. Electric heaters are cheaper to run, but you need to make sure that your garage has a suitable power supply.

2. Cabinet size: You need to make sure that the cabinet will fit in your garage. Measure the available space and check the dimensions of the heater cabinet before you buy it.

3. BTU output: The BTU output of a heater is an indication of the heat that it produces, and is usually calculated per hour. To decide which heater to buy, you need to multiply the length and width of the area that you want to heat by the BTU rating of the heater.

The result will tell you the number of British Thermal Units (BTU) that the heater will produce in one hour. You can then compare that number with the area that you need to heat to determine which size of heater you need.

A 400 square foot garage that needs to be heated will require a heater with at least 8000 BTU. If the required heat is less, you can get away with a smaller heater. If the required heat is more, you will need a larger model.

4. BTU Input: The BTU input of a heater indicates the amount of heat that the unit is capable of absorbing and holding for later use.

If your garage is large and requires a large amount of heat, you will need a heater that can absorb more heat.

If your garage is small and requires only a small amount of heat, you will need a heater that can absorb little heat.

5. Adjustable Fan Speed: Some heaters have a built-in thermostat control, while others don’t. If the heater that you are considering buying doesn’t have a thermostat, make sure that it has an adjustable fan speed.

The fan speed of a heater determines how quickly the heater absorbs heat and delivers it to the surrounding area.

A higher fan speed means that the heater absorbs and delivers heat faster, while a lower fan speed means that the heater absorbs and delivers heat at a slower rate.
