In A Hurry? 

Icicles coming from your face when you are working in your garage? Or maybe your hands are too cold to actually be able to hold your tools correctly? If any of this sounds familiar then you are in desperate need of a garage heater – and we are here to help! 

Power and Heating Area

The first thing that you need to look at is the amount of power that your garage heater is going to provide. This will determine not only the temperatures that it is going to be able to get to but also the distance that it will be able to force the heat to and therefore the area that it will be able to heat up. 

We found that powers tend to range from around 3kW all the way up to around 10kW. A 10kW heater is obviously going to be able to heat a much larger area than a 3kW model would, but a 3kW is going to be more energy efficient and practical if you actually only have a small area that you are needing to heat. If you are wanting a model that can be used with a standard plug socket then the highest you are going to be able to get is a 3kW model, any more than that and you are going to need a generator that is able to work with more power! 

Most manufacturers will give a rough idea of the area that their garage heaters are going to be able to heat but there are a number of factors that this is going to be affected by. We found that variations in heating area ranged from around 20 metres squared up to around 200 metres squared. Most electric heaters will heat between 20m – 100m squared, whereas the larger gas powered models will be able to heat all the way up to the 200 metres squared if needed! 

NOTE: If your garage is insulated then you won’t need a garage heater that is as powerful as the space should stay warmer for longer. 

Power Type 

Don’t forget that you are going to need to consider exactly how the heater is going to be powered. Your two options will be either electric powered or gas powered. You will find that electric powered models are going to be much more popular, simply plug them into a socket and the garage heater will start to heat up. This makes them really handy to use in a wide range of places and nice and cheap to run too. Electric garage heaters are going to be smaller and lighter, which makes them perfect for if you are working in a smaller space, just make sure to consider if you actually have power where you are wanting to work! 

Your other option is going to be a gas heater. A gas garage heater is great for if you don’t have power in your garage as you will be able to place your heater (and the gas canister) anywhere and it will still work. You also normally find that gas powered garage heaters provide more power and more heat – they will even be able to heat larger garages or spaces where you may be working. Your two choices will be either natural gas or propane gas – which really just comes down to personal preference. However, you do have the downside of having to purchase the gas canister – which is going to add to the cost as well. Plus, this is going to increase the overall bulk, which you may not have space for in your garage. 

NOTE: Some gas garage heaters won’t actually be suitable for indoor use due to the emissions that they give off! This is really important to check for before you buy as the carbon dioxide build up inside could be really harmful!

Heating Styles 

You need to think about the type of heating device that is going to be right for you as well. There are two main types that you will be able to choose from – infrared (or radiant) heaters and fan heaters. 

Infrared heaters work by heating objects that are near them – which is a slightly different way of working. The infrared technology is used to actually heat up the “things”, for example you and your car, rather than heating up the air. This is a much more effective way to keep you warm whilst you are working but does mean that the actual garage itself isn’t going to benefit quite as much – which could then lead to damp or you not feeling the benefits quite the same if you are moving around the space! 

Fan (or heating element) heaters are the more traditional option that you will find. These work by heating elements and then the fan pushes the warm air around the element out into the room so that the air is always circulating and moving back to the heater to be warmed again. These are arguably less effective as they are going to be trying to heat up the whole space, however, this could quite possibly be what you need for a garage heater! Just bear in mind that they aren’t going to be nearly as economical because they are trying to heat the whole space rather than just the one little area that you are working in! 

TOP TIP: If you have young children or pets then it may be a good idea to look out for models that have cool to touch technology (normally found in most infrared models). This means that even if their fingers get near the heater, they shouldn’t end up with a burn like they would with more traditional models. 

Build Materials 

You need to know that the build materials of your garage heater are going to be up to the task. Unless you have some super garage then they aren’t known for being the cleanest and driest of places so you need to know the garage heater will be able to cope. 

Generally, we would only really recommend models that come with a metal frame. Providing the metal frame is powder coated it should be rust resistant and therefore long lasting. Plus, if it is knocked when you are working then it should be able to withstand the force! Metal is going to be slightly heavier than the plastic models – and slightly more expensive – but they are going to last much longer as we found that some of the plastic frames can crack if they are knocked over! 

If you do go for a metal option then it may be worth checking to see if the heater comes with rubber feet – you may not be precious about the floor of your garage but if you are then you are going to need this to avoid scratches! 

The Best Garage Heaters

Here are some of the features that we found in the best garage heaters. If you are in your garage a lot and need a heater that you can really rely on then this is what you need to be looking for! 

  • Adjustable Heat Settings – We really like models that come with adjustable heat settings. This will allow you to get just the right amount of heat in your garage for the time of year! 
  • Thermostat Control – Some of the best garage heaters will even come with thermostat controls so that you can control exactly just the amount of heat that you want. This saves you from having to adjust the settings regularly when you are concentrating on the job that you are completing. We also like this option over winter if you have a classic car or woodwork that you complete in your garage as the garage heater will be able to keep a constant temperature without overheating! 
  • Heater Overload Safety – Look out for garage heaters that come with overload protection so that if the heater becomes too hot it will switch off and you can avoid any damage. 
  • Tip-Over Switch – This is another great safety feature that you should look out for. Models that come with a tip-over switch will switch off if they fall over. You may think this isn’t going to happen but you never know so it is better to be on the safe side! 
  • Weight – Chances are you are going to need to move your garage heater around so make sure to check the overall weight. We found that garage heaters can range in weight from around 3kgs up to around 9kgs. 
  • Portability – If you know that you are going to be wanting to move your garage heater around then look out for models that come with handles and wheels. This makes it much easier to move around the space as and when needed. 
  • Brackets and wall mounts – On the other hand, if you know that you want your garage heater fixed in one place then why not look out for models that come with a wall bracket so that they can be secured on the wall and fixed in one place out of the way. 
  • Twin Heating Elements – This is going to be the best way to get the most heat from a smaller machine! Twin heating elements are going to offer double the heat for a smaller space and mean that you get that heat even faster! 
  • Size – The overall size of your garage heater is important as you need to know that it is going to fit in the space you have available. We found that sizes started at around 20cm x 20cm x 30cm (length x width x height) and went all the way up to around 50cm x 30cm x 40cm.
  • Hose length – If you decide that a gas garage heater is going to be right for you then we would definitely recommend checking the length of the hose that comes with the heater. The longer the hose the more you will be able to move the heater around the space as needed without having to have the gas canister right next to it!

Frequently Asked Questions 

Will garage heaters come with a warranty? 

Yes! All garage heaters will come with at least a 12 month warranty however some of the best models will come with a 2 or a 3 year warranty. Make sure to check exactly what is covered under this warranty though as many won’t be covered if the model has overheated. 

Does a garage heater need to be waterproof? 

Providing your garage is relatively watertight then you shouldn’t really need it to be waterproof. However, a certain level of water resistance is definitely not going to go amiss! We would recommend looking for at least a rating of IP44 as this means that it is safe you use and will be safe from the odd splash!
