What to Look For In a Best Propane Heater for Garage, House & Patio
When you choose to buy a best propane heater for garage, house & patio then you have to pay attention to certain factors. For instance, you should have in mind the size of your garage, the kind of cars you have as well as the security features. You see, your propane heaters should neither leak nor catch fire because certainly, you don’t want any disaster inside that place. Anyway, here are considerations to help you find a good propane heater.
If your garage is too small, you will certainly not want to use a powerful heater. You see, you don’t want the place to be too stuffy or hot. Small garages require a less powerful heater that can cover the limited space, while the larger ones deserve a powerful heater.
Some heaters come with a freestanding feature, which means they can sit on the ground and allow portability and versatility. It’s easy to move these heaters around and even get them to your garage, or in a tent. Some people even put them under their legs, especially during extreme winters.
Wall-mounted heaters, on the other hand, are fixed, but they are more powerful. The ability of this heater to feed a whole garage largely depends on the diffusion mechanism. You see, the only way the heat will get to the corners of the garage is through pushing hot air all over. Some heaters use fans, while others are radiant.
So, when you have a large garage, you can decide to use multiple heaters or find a fan-forced heater. Or, you can find one of the most powerful heaters such as this one .
Source of Power
How does your heater get its power? Does it rely on natural gas, electricity or propane? Every source of power has its cons and pros, and you have to make sure you have one that fits your convenience. All these heaters will be good depending on your type of garage, or the situation.
For instance, if you want to get an eco-friendly heater, you will certainly want to use the electric heater. The natural gas heaters are good for people who have large garages, and for people who want to save dollars. Then, propane heaters are ideal for powerful output.
Natural gas-powered heaters
Millions of people across the world prefer natural has heaters due to their easy installation and maintenance. It’s also cheap to use natural gas because it’s affordable at the station. And, natural gas is efficient, and you only need to install has lines for your garage or house.
However, we have to admit that the costs of installing a natural gas heater are quite high. The good side is that after you have the heater, the maintenance costs are low.
Also, understand that natural gas heaters come in two types; the fan-forced and the radiator. The fan-forced garage heater has a fan that diffuses hot air around the space. Then, the radiator has an infrared tube that produces heat which then spreads out to the rest of the room.
You can use LPG or natural gas to fuel any of these heaters. And, because the natural gas can burn into toxic fumes, you must come up with a convenient venting system that eliminates these gases.
Electric garage heaters
The majority of urban dwellers recognize electric heaters. At least, these are compact and don’t require any sophisticated maintenance skills. Electricity heats thermostats, and the infrared heat diffuses to the rest of the room. Electric heaters radiate a consistent flow of superheated air. If you have medium-sized rooms, the electric heaters are your best option.
And, the electric variety normally has an automatic switch-off feature that allows them to sense when the heat goes overboard and control the temperatures.

Radiant and infrared garage heaters
Sometimes, you may want a localized heater that provides heat at a specific place. Think about a fireplace. The radiant-infrared garage heater generates powerful heat, especially for heating a small space. The wall-mounted infrared heaters are fixed, and you need to stay around them for warmth. But, the freestanding heaters let you walk around with them and even put them under your legs. Buy some of the best radiant infrared garage heaters here.
Fan-forced garage heaters
When you are looking for the best propane heater for the house, get those that can full your entire house with heat. Hot air needs to be circulated evenly throughout the room. So, a fan-forced heater draws cold air and then ejects heated air. The heat is then blown around the room, and this warms up the room quickly.
However, this heater isn’t the best for small rooms because they can easily become stuffy. Advanced varieties allow you to switch off and control the temperatures.

Power Output Level (BTU)
Another important feature you need to look at is the power output. Heaters come with a calibration that denotes the British Thermal Unit (BTU), which is basically the amount of heat that the device can generate.
Small heaters have BTU of 4000 to 9000, like this one . Such a heat output works well for small garages with an area of up to 250 feet squared.
In case your garage is 500 to 600 square foot, then you might want the 25,000 BTU heater.
And, when your garage is more than a thousand feet, then goy will need heaters that can yield more between 30,000 and 60,000 BTU. Our recommended heavy-duty heater for large garages is this Dyna Glo RMC from Amazon
The security of your heating appliance should always be top of your mind when choosing a heater. Certainly, you want to be sure that it’s safe to use the heater. Remember, heat, when mishandled, can cause extreme damage. And, because you care about your life, your loved ones and property, you must pay attention to the safety standards of the heaters you use.
Wire Guard and Cool-Touch feature
Some advanced heaters such as this one on Amazon come with an extra surface that protects you from the heat. The wire-guard feature ensures that you don’t get into direct contact with highly heated surfaces.
Protecting the heater is a crucial part of the heating process. At least, you want to have consistent warmth in your house without destroying the device. So, find out if the heater has an automatic shut-off functionality.
Some models come with an inbuilt high-temps auto-switch that turns off when there’s overheating. Also, some gas-powered heating devices have safety sensors that protect the heater from blowing into flames.
Sensor and Tip-over switch
Heaters can sometimes fall off, and you need to ensure they don’t get damaged. High-quality heaters come with a sensor and top over switch that shuts off to ensure the heat does not cause damage in your garage. Have a look at this one for more details.
When using a heater, you need to have the power to control how warm your house can be. And this all boils down to the setting menu. Advanced heaters come with a user dashboard from where you can set temperatures you want for your house. Adjusting the heat lets you decide your level of comfort.
Some thermostats come with low-high settings. So, you can decide the best temperature for your winter mornings or the most comfortable for the summer.
The Cadet Portable Heater has some of the easiest settings on Amazon and could be worth being added to your cart.
Make sure your portable heaters have an ergonomic handle. Of course, you will need to move around with your heater without burning yourself. You, therefore, must find a heater whose handle gives you enough grip. We recommend rubber or synthetic handle like the one in this heater here.
Length of cord
When you decide to use an electric heater, you need to ensure the cord is long enough. Remember, the manoeuvrability and portability of your heater depend directly on the length of the cable. The standard heater comes with a 6-foot power cord such as this one here.
Then, when you’re using propane gas heaters, you should look for a long hose. Dyno Glo RMC prides a 10-foot hosepipe for additional portability.
How BTU’s are counted and how many will I need?
The thermal output of a heater is measured in BTU per hour for propane-powered heaters and Watts for electric models. High BTU or wattage shows that the device produces more heat per square feet.
How do you calculate the BU and wattage? Of course, you need to be sure that the heater you are taking home is good enough for you. So, you must calculate the wattage or BTU.
First, you should calculate the amount of heat you need to warm your house. It’s simple, as you only need to multiply the area of the room by eight. You’ll get an approximate figure of the energy needed to make your house comfortable. However, you have to be alive to the fact that this figure depends largely on the ceiling, climate, weather and ventilation.
And for easy calculation, you can find the BTU and AFUE rating on each model of propane heater you want to buy. The AFUE rating indicates the rate of efficiency for every device per BTU/hr. In short, the AFUE efficiency rating is a percentage showing the heat produced per every unit of propane gas burnt.
Are Propane Heaters Safe? Safety Precautions (Safety Features)
The heater should have an oxygen depletion sensor (ODS) that monitors the levels of carbon monoxide and oxygen in the room. Then, when oxygen is too low, the monitor cities of and when the carbon monoxide is too high in the room in the device is going to switch off automatically.
