What Does the Best Garage Heater Look Like? 

When shopping around for a heater to keep your garage or other type of out-building warm all year round, you may become overwhelmed by the sheer amount of models available on the market. That’s why it’s so important to choose a garage heater that has a great reputation and the ones that do are typically very efficient, helping to save you money and come equipped with a range of safety features for maximum peace of mind.

The Garage Heaters Available: 

First things first, you need to be aware of the types of garage heaters available with differences they have and which may be most suitable for you and your circumstances. For instance, some types of heaters are best suited for home garages, while others are more industrial; suitable for large, commercial garages.

Fan Heaters 

This type of garage heater includes a built-in fan and are straightforward to set-up and use. As a result, they are perhaps the best selling type of heaters for garages. They utilize electricity which is transferred into heat, a fan takes in the cool air from the environment and re-circulates it back into the garage once heated via a heating element. This has the effect of quickly heating the space.

Radiant or Infrared Heaters 

Radiant and infrared heaters work by directing heat energy waves directly that are absorbed by other objects and so heating them in the process. Unlike, fan forced heaters they are more comfortable since no noisy fan is used to direct the warm air, however, the main issue is that they have to be located in close proximity in order to experience the heat and they aren’t very efficient at heating large average to large areas.

Diesel, Kerosene or Natural Gas Heaters 

These types of heaters utilize natural fossil fuels instead of an electrical power source or battery pack. They are very effective at heating up large areas and are extremely portable since they don’t require a connection to the mains. However, be cautious since they have the potential to be more hazardous in small and enclosed spaces.

How Much Energy Will your Garage Heater Require?

The majority of garage heaters will provide information on the amount of power required to keep it running. This information is provided as a BTU value. The greater the values, the higher the amount of watts are used. Take note, however, that the value provided comes with the caveat that it refers to the optimum circumstances. Therefore, it is recommended that you select a heater that has a higher heat output than you will probably need, this will help cover any issues that may lead to a loss of heat, such as any back draft issues within your garage.

The size of your garage is an important thing to consider when shopping for a heater, for instance, if your garage is relatively modest in size then a radiant or infrared heater is preferred. These types of garage heaters operate at their optimum in smaller spaces since they directly heat surrounding materials and not the air, as a result, they don’t typically lead to heat loss from ventilation or large draughts. However, fan forced heaters can work in small garages too, for example, a 2kw heater would work in a small garage, whereas a large garage or out building would be best suited to using a heater of around 3,000 – 6,000 watts.

Look out for these Safety Features: 

When shopping for your garage heater, it is wise to choose a model that comes equipped with safety features such as those listed below to keep you safe whilst you are working.

  • Overheat Protection 

Since you will probably be operating the heater for prolonged periods of time, it is probable that it will occasionally become overheated, which is, a potential hazard. As a result, the best models are equipped with overheat protection which means the heater turns itself off to prevent any damage occurring as a result of high temperatures that can also potentially lead to a fire hazard or damage the components of the heater.

  • Tip Over Mechanism

Unfortunately, accidents can happen and sometimes the heater can get tipped over especially if the wire is in a walking zone. Active environments such as garages and workshops are even more likely to pose a hazard, therefore, securing a heater that’s equipped with a tip over mechanism  is a good option. If the heater accidentally tipped over, it will immediately switch off.

  • Cool-Touch 

At times when you are operating a heater around people, and in places of work such as table-tops or floors, if possible you want to avoid it becoming too hot to touch. It’s quite easy to forget such risks, rendering heaters that overheat potentially very dangerous. As a result, always opt for cool-touch models for optimum peace of mind.

Garage Heating Efficiency

So that you can easily maintain a comfortable temperature in your garage, even throughout the colder periods of the year, you’ll need to ensure that it is heated as well as possible. While using a garage heater can certainly help, it’s important to consider other factors which contribute to keeping out-buildings such as garages warm and comfortable throughout the year.

  1. Insulation– One of the most important things to think about is the insulation of your garage. Outside buildings such as garages are not intended to be well-heated, therefore, good insulation is not often considered meaning draughts are common and heat is easily lost to the outside environment. Therefore, use a high-quality type of insulation on the walls and the ceiling to slow down the loss of heat.
  2. Installation– If you are opting to use an infrared heater, it is important to install it at a  minimum of 7 ft. above the floor.  It’s essential that you make sure objects below are not too close for safety purposes. In addition, if you opt for using a gas heater, you will need to consider ventilation, while an electrical heater will need easy access to the mains.
  3. Type of heater– Make sure you carefully consider the type of heater that is most suitable for heating your garage. For instance how big is your garage? You will need to measure the size of your garage and decide on how quickly you’ll want the garage to heat up. Ensure you check the BTU rating and watts which provide a good idea of the intended area it is designed to heat.

A basic guideline for forced-air heaters is 45,000 Btu from a two – two and a half garage, and 60,000 for a three-car garage.

Garage Heating Advice 

garage heating tips

Whatever you plan on using your garage or workshop for, whether that be a entertainment hub or storing a car or two, you will likely want to warm it up during the winter months. So if you want some hints and tips on how to keep your garage well-heated safely, then continue reading.

One of the first considerations is whether to use a portable heater or a fixed heater in your garage. It is strongly advised that you opt for a fixed model as portable garage heaters can be hazardous since they are easy to tip over and utilize flammable gas. In addition, many materials frequently used in garages are highly flammable, such as gasoline and turpentine.

There is a wide selection of garage heaters including ventless, closed combustion, and radiant panels. It is a wise idea to avoid smaller models since they are typically unable to heat poorly insulated or large garages very well.

It is also important to consider the most appropriate way to use a heater in your garage. For instance, it is recommended that you install your heater well above the floor and away from any table tops that are in frequent use. A freestanding model is likely to be inappropriate since they can block walkways and are easy to tip over. Alternatively, you should install your heater on to the wall or the ceiling. The majority of heating models enable you to control the transfer of heat, therefore point it into the middle of the garage, or in the direction that you will be spending the majority of your time. This will ensure the greatest heat pay-off from the heater.

You should also consider the type of door and insulation used in your garage; both in terms of energy efficiency and fire safety. This is a topic I will get into in a future blog post, but the best rated garage doors and building materials are something for you to consider if you are replacing your old door or building a new garage from scratch.

Are Gas or Propane Garage Heaters Safe? 

A propane heater to warm your garage is fine and many people do this, but it is essential you do it safely and are aware of all the potential hazards. For example, there should be adequate ventilation in the area that will safe oxygen levels to be maintained during use. Additionally, you should avoid using combustible substances in your garage if your propane heater is operating, as this is a potential fire hazard. If this is an issue you may want to consider using a different heating system and not a propane or gas garage heater.

If you decide to opt for a propane heater to heat your garage, then you may want to consider using those marketed to do so. This doesn’t mean you will have to station the heater outside, but the indoor propane heaters typically hold smaller propane cylinders. If you think you might need a bigger gas cylinder, then you will likely need to choose a larger model and therefore keep it outside only.

Don’t forget that there is a vast array of other types of heaters available, so before you consider a propane heater, it’s a wise idea to think about all your options. There are many models that have been designed entirely for garage use.  If you have an electric power source, then it’s likely that an electric heater may be more suitable.
