Buying Guide

1. Purpose

Propane burners are perfect tools for your uninsulated garage. But do you know the exact type of heater that you would need for your garage?

This guide will serve as a tool in which we will discuss all the necessary items that you would need to consider when choosing the right propane heater for your garage. 

Many layouts and functions are coming from a variety of heater brands. They all work the same way but their output varies.

2. Power Output

The power output of your heater should be proportional to the size of your garage. Having a heavy-duty heater is nice but the heat output might be too much for your garage and it might harm its immediate surroundings. 

Your choice must be based on the needed output of the total floor area of your garage. So the first thing you should do is to know the total floor area and to find a safe place to install your heater. 

The next is to find the right heater which has enough heat output for your garage. And besides, you do not need to raise the temperature of your garage too high. 

3. Safety Features

Since this type of heater runs on propane gas, safety should be of the utmost priority. Choose the heater with an automatic shut-off feature. 

These types usually come with various sensors that tell the heater if it is still operating in optimal conditions. Otherwise, if it senses danger, like low oxygen levels in the surrounding, it will automatically shut off. 

4. Forced Induction Or Not

Conventional heaters just emanate infra-red heat from their exhaust without the aid of fans. On the other hand, some heaters do have forced induction, which means that it sucks in cold air and blows out the heated air. 

This type of heater is somewhat effective as it aids in circulating the heat faster around the area that it is heating.
