Many turn to the best gas garage heaters, which are an option whether your garage has a mains gas connection or not.
Gas heaters can be very cheap to run and do an exceptional job of keeping your garage at a stable and comfortable temperature, but you need to make the right choice when buying one.

Reviews of the Best Gas Garage Heater
Mr. Heater is a brand name which you will likely see a lot when searching for a garage heater. Their offerings in the market of gas heaters are superior to most other products, and the F260560 is a powerful and reliable heater.
This heater offers 80,000 BTU, which is a lot of power, and can heat large spaces including big garages and even barns or workshops.
Although this is a gas heater, the fans for venting do require AC power, so it will require a power socket too. This is somewhat counterproductive if you want something that can use just gas.
This gas heater is responsibly made for use with natural gas, and if you have a supply of this then you don’t need to modify anything. The product uses a 0.5- inch gas connection. If you wish to, you can convert the heater using a kit that comes with the product. This will allow you to use liquid propane to run the heater.
Installing is extremely easy, and the brackets needed to install on a ceiling or wall come with the heater.
The build quality is clearly excellent, which is what you would expect at the price. The F260560 is one of the more expensive products we’ve recommended. If you are looking for something with some power to heat a large garage then this could be a good option. The manufacturer even offers a three- year limited warranty on parts and burners, so you can rest assured that it is made to last.
Another model from prolific brand Mr. Heater is their vent free gas heater. This offers a lot of quality and heat, combined with convenience. It is easy to install and doesn’t require the venting that a lot of other gas garage heaters need.
The heater has a thermostat built in, this is one of many features to make your life easier, and means that the heater can be set to kick in at a certain temperature and warm your room to a precise level. It can give off up to 30,000 BTUs, which is less than some competitor products but still enough to heat up to 1,000 square feet, so as long as your garage isn’t huge then this heater will do the job nicely.
Starting the heater is done by a battery and this is already included in the product when you get it. The fact that this doesn’t need to be vented means that no electricity at all is required, so even in a power blackout you can use your heater. Safety features including an Oxygen Depletion Sensor mean you can rest easy knowing your heater has been fitted with precautions.
Fitting is simple too, with brackets included to either secure the Mr. Heater on the wall or the floor, depending on your preference.
The price point for a gas heater is very attractive to most people. It gives a blend of having plenty of features but also great value for money.
If you have a massive space to heat, then this isn’t the one for you. However, there are a lot of very impressive features to this tiny portable heater, making it a popular choice for people who need something they can move around.
The F232000 runs on propane and therefore doesn’t need any form of electricity. As it has been designed for use both indoors and outdoors it is resistant to all kinds of conditions, and can be used with no electricity for venting. It can make use of 1lb cylinders of propane or be attached directly to a tank.
The heat offered is between 4,000 and 9,000 BTUs, which isn’t a huge amount of heat, but is not to be ignored either, especially if the space you want to heat is relatively small. Of course, the fact that this is portable means you can move it closer to where you are working in your garage to ensure you maximize the heat.
Because it is portable, the Mr. Heater F232000 has been fitted with a lot of different safety features. It will automatically shut off if it is tipped over, if the pilot light fails or if there are low levels of oxygen.
Because of being small and portable, this is one of the cheaper models you can buy. It is a little more expensive to run if you are constantly buying smaller propane cans, but has the added benefit of being easy to move. If you don’t need to heat huge spaces, this can do any garage up to 200 square feet with relative ease.
A product not manufactured by Mr. Heater. This product is similar in price range and features to the Mr Heater 30,000 BTU model. It has the added bonus of being extremely simple to mount on your ceiling or wall.
The Heatstar offers plenty of heat for up to 600 square feet of a garage (this means over the size of a standard two-car garage). It is efficient too, and in spite of using propane, the 99.9% fuel efficiency means you don’t have to spend a fortune on gas.
The included thermostat is all you need to hook up before you start using this. This will control the valve with no need for any electricity, which is a big plus point over some of the other models which do require electricity for venting and starting purposes. The Heatstar can be used even in power outages.
The tank capacity is 40lb meaning it can burn for a long time without having to be refilled. Installation is very simple via a wall bracket and the compact design means it doesn’t take up a lot of space in your garage.
This is well built and made out of non-corrosive materials ensuring a long life if it is treated correctly.
Overall this is a very reliable and well-made product with the added bonus of needing no electricity whatsoever.
Gas Garage Heaters and Safety
One concern people often have regarding gas heaters is their safety. Many of us have heard horror stories about these types of heaters, worrying about carbon monoxide or nitrogen leaks.
Products such as these have to take the correct precautions, and used correctly then you have nothing to worry about. If your heater is vented then the fumes will be released outside which means that the impact on your garage in terms of harmful fumes is zero.
If you opt for one of the ventless heaters then it may be worth letting some air in from outdoors and ensuring there is some sort of ventilation. This is a caution, and the products we’ve listed come with sensors and safety features to ensure that the levels can’t reach a harmful stage.
Carbon monoxide poisoning is something people are concerned about, but most of the best gas heaters have a level sensor of some kind, to ensure that dangerous levels are not reached. It is best to follow the advice of the manufacturer depending on which model of heater you opt for.
In general, you can rest assured that there aren’t big risks to using these products as long as you don’t do anything silly.
Gas or Electric?
This is a decision you need to make before purchasing a heater. Naturally, some heaters suit better homes than others.
Some people will only have electricity and no mains gas in their garage which can lead you to prefer an electric heater. That said, many of the gas heaters run on propane so don’t need to be hooked up to a mainline.
Electric heaters also often require 240V power outlets, which not all of us have in our garages. Getting this modification can be an extra cost that puts many people off and is not something you need to worry about if you opt for gas.
Gas heaters are known for being efficient and cheap to run. They may cost more up front but many models will save you money long term. The best gas heaters can cost pennies per day to run. Some electric heaters can really sap your power and lead to big bills and spikes in your bills when it gets cold.
In terms of any environmental debate, most of the products we’ve mentioned run on either propane or natural gas. Natural gases are a great way to stay almost 100% eco- friendly and ensure your carbon footprint isn’t affected by heating your garage.
Gas heaters aren’t perfect, they do often require ventilation, unless the model you have purchased is a specific ventilation free design. Many are also worried about some of the perceived hazards of using a gas heater, but as we’ve covered, these aren’t usually a big issue.
Your choice may well boil down to the power or gas you have available in your garage.
