Propane Garage Heater: Uses, Pros, Cons and Alternativess

A propane garage heater can be used not only for heating your residential garage, but also for any other commercial heating purpose. Propane heaters use pressurized LP (liquefied propane) gas to quickly heat non-insulated spaces, including construction sites and garages. They are extremely handy and many models are portable.

Propane heaters are great as garage heaters since they are very cost effective. Heating a non-insulated garage with an electric heater can add a lot to your electricity bill. However, a propane fired heater can generate heat when you need it, and quite efficiently.

Things to consider before buying a Propane Heater

The size of your heater depends on the size of your garage. Larger garages require more BTU (British Thermal Units) and vice versa for smaller garages.

Your heater should have a thermostatic temperature control to automatically shut down the heater once a certain temperature is reached. A low oxygen sensor in a garage heater is also a nice feature if available, as it will turn off the heater if oxygen levels become too low.

If an LP garage heater is mounted on the wall or on the ceiling, adequate clearance around the heater is very important.

Pros and Cons of an LP Garage Heater

The great thing about an LP garage heater is that they run on liquefied petroleum gas, which is very eco-friendly. You will also save on your electricity bill.

Some downsides to using propane heaters are that you will have to refill the propane and you need to be aware of leakage. Propane heaters also require adequate ventilation for safety.

Alternative Garage Heater Options

Apart from propane garage heaters, which are extremely economical and energy efficient, there are other options, including electric garage heaters and many naturalgas garage heater models.

An electric garage heater is extremely easy to install and does not require ventilation. Electric heaters can be portable or permanently installed, and they are typically fitted with a number of safety features. However, the operating cost of an electric heater may be high, especially when it is very cold and if your garage is not insulated.

A natural gas garage heater, like propane models, will require ventilation in the garage. Though the upfront cost of a natural gas model is more than other options, the operating cost is much less. In addition, the fact that these heaters are environment friendly makes them even more desirable.
