Do you fall in love with items with a convenient remote control? Then you should have a look at this Heat Storm HS-1500 infrared heater, which comes in both big and small sizes.

The remote control helps you alleviate lots of problems, and especially comes in handy for people who are often forgetful. For instance, are you unsure whether you have switched off the heating before retiring to bed or not? Simply check your phone's app. It is also a good idea to preheat your workplace before you go on with any task or project of that day. All you need to do is activate the app, and everything is ready.

The Heat Storm HS-1500 is a mounted burner, which keeps it out of sight and makes the house's layout look much neater. Also, the 120V socket makes installation simple. And though the manufacturer makes no mention of the Btus, but based on the wattage, we are certain this sensible heater should be enough for enclosed garages that require just about enough warmth to keep things comfortable.

If price is a key consideration for you, then look no further. We are certain that this Pelonis 1,500-watt heater would be the best option for you - and apparently, more than 8000 reviewers on Amazon also think the same. Widely beloved by many users, Pelonis 1,500-watt heater claims its deserved spot on our list.

Indeed, it is not an exaggeration to say that Pelonis 1,500-watt heater is the most affordable heater on our list. Despite the price, this item is still quite powerful. It can operate at 120V and produces roughly 5,000 Btus - a quite impressive feat that is comparable to many other more modern products. Though that might be insufficient to heat a large carport, this heater is still enough to warm you up when working at a worktable.

In addition, this radiator heater provides constant and consistent heat without the need of an open flame. (The oil is not needed to create heat; the heaters are a self-contained unit that should never require topping up.)

If you operate a heater with running motors (or equipment that emit fumes), you probably prefer to keep the door unlocked. If this is the case, we are afraid to tell you that nearly all of the items on this list would be ineffective. For such scenarios, you will need significant air movement, which means that only a high-Btus item can fulfill your demand in an open-air environment.

That is why we believe the Dyna-Glo 180,000 Btu heater is the best option for you. The Dyna-Glo 180,000 Btu heater operates on kerosene (or diesel fuel) and has a maximum heating capacity of 4,000 square feet.

In truth, this item is not suitable for confined or small-scale locations, since it is very loud, needs extensive ventilation, and generates moisture that might condense on your gear. However, with an opened overhead door, all of these mentioned disadvantages will vanish in a blink, leaving a significantly warmer work atmosphere for you to carry out your tasks.

As with any kind of garage heater, propane heaters also have their own set of safety considerations. In this instance, carbon monoxide is produced during the combustion process and must be vented correctly outdoors. When used properly, propane units are efficient and convenient heating options, and the finest alternative on the marketplace right now is this Mr. Heater MH60QFAV.

Mr. Heater MH60QFAV is a "torpedo heater" - this nickname stems from its current shape. This propane pressured air heater creates heat that radiates out from the wide end and can warm up to 1,600 square feet of space, with a maximum output of 60,000 BTUs. It's also a transportable propane heater, which means you can use it wherever you have a gas tank (and an adapter to power the device).

This Mr. Heater MH60QFAV gas garage heater unit is an excellent deal, thanks to the insane amount of heat it creates. Apparently, many buyers have taken note of that; it is now Amazon's fourth-best selling space heater.

Electric garage heaters are sometimes seen as being less powerful than their fuel-burning counterparts (for many people, a gas heater or liquid fuel heater may provide more heat). But the truth is that a high-quality electric heater can also fulfill your warming demands. The Fahrenheat FUH is a good example. The Fahrenheat FUH has an average power output of 5,000 watts, coupled with a thermostat that adjusts from 45 to 135 Fahrenheit degrees.

This electrical garage heater must be wired (instead of plugged in). That means it must be installed correctly by a skilled electrician. On the bright side, the compact size of the heating unit allows it to be placed and fixed in a number of different positions.

If you want a more potent heater, then opt for the FUH54 model (which has a maximum heating capacity of 7,500 watts) or the FUH1024T model (whose maximum heating capacity reaches 10,000 watts). All in all, a typical Fahrenheat FUH should provide enough and dependable heating for an average-sized garage.

Mr. Heater is a market leader in heating systems, and the Mr. Heater HU80 — also referred to as the "Big Maxx" — is an excellent illustration of how robust their products can be. It is not only the greatest natural gas heater on the market, but it's also our top selection for heating large garages.

With an output of 80,000 BTUs per hour, the Big Maxx organic gas heater is an excellent choice for heating garages up to 2,100 square feet. These pressured air garage heaters operate by a blower that draws in the chilly air and warms it before releasing. Since the item is rather huge – it weighs about 85 pounds – its power is incredible. The hefty weight of this item might prove troublesome sometimes, but if correctly placed, it will not be much of a problem.

Please keep in mind that this Mr. Heater HU80 requires an electrical outlet to power the fan and a gas supply to heat. The equipment for connecting the heater to a gas supply is not included, but may be purchased separately.

The product will provide enough heat to last 12 hours. In addition, this Kerosene Portable Heater is built for ease of use and safety.

Are you looking for a simple and affordable (yet still high-quality) heating solution for open garages? Chances are you will not find a better deal than the Remy REM-16-TTC-O - we are certain of it! This item has a quite low price, but that does not mean its functions are lackluster. In fact, this portable propane-powered heater can produce an astounding output of approximately 16,000 BTUs. Such a feat is incredible, even for some other much more pricey items.

This REM-16-TTC-O can operate without power, which is very convenient. You just need to connect it to the base of your gas cylinder; once done, it will provide the necessary heat for your household.

This item also has some safety precautions, such as a shut-off lever and a tip-over switch. However, these buttons might become quite hot while in use. Hence, it is critical to avoid touching anything near the heat source while the system is running.

If you need to heat a big garage – such as a multi car carport or workspace – you'll need a strong gas garage heater, which is often more expensive. Actually, there are deals at every price range, but if you have decided to go for the most appropriate heater, it's worth examining the Modine HD45AS0111 — one of the company's "Hot Dawg" market segments.

Although this type of heater is more expensive, it is functional and adaptable. Users on Amazon rave about how rapidly it warms their spaces; and although it is meant to be an oil and gas warmer, it can easily be changed to a methane garage heater if necessary or preferred. It includes a tailpipe that must be vented out in order to eliminate hazardous gasses.

Finally, it's worth noting that this Modine HD45AS0111 heater is just one item among many in the Hot Dawg line's air heater items. Your requirements may differ depending on your space and budget. The product range includes six heaters with a combined output of 30,000 to 125,000 BTUs.
