Buying Guide: How To Choose A Garage Heater

If you are looking for the best garage heater for your garage or workshop, you may be feeling a little daunted at the choice that is available. It is true that there are hundreds of models out there to choose from, but there’s no reason why choosing the right one for your needs should be so difficult when you know what to look out for.


Types Of Garage Heaters

The first thing that you’ll need to do is find out what types of garage heater you can purchase. There’s more than just one style, so it’s important that you pick the one that will be able to provide you with enough heat depending on the purpose that you need it for.

  • Fan-forced garage heaters

    These garage heaters have an integrated fan and they are easy to install. They are possibly the most popular garage heater type. Electricity is converted into a heat and then a fan draws in cold air from the garage and then blows it out once it has warmed up over the heating element. They can heat the room quickly and produce a lot of heat.

  • Radiant or Infrared garage heaters

    A radiant or infrared style of garage heater directs heat forwards to objects that are close by. They work in a similar way to the sun so they also provide a more comfortable heat than fan forced heaters. The problem with these heaters, however, is that you need to be fairly close to them to enjoy the benefits so they’re not as popular as the fan forced heaters.

  • Diesel, kerosene or natural gas garage heaters

    These kinds of heaters are powered by fuels rather than electricity. They can heat up a garage very quickly and as they don’t require an electricity supply, they are highly portable. Although they are great for heating larger areas, you should take care with one of these kinds of heaters, as they can be dangerous to use in an enclosed space.

How Much Power Does Your Garage Heater Need?

When you purchase a garage heater, it will give a power rating in the form of BTU. The higher the watts and the BTU of the heater, then the more powerful the heater will be and the larger the space that it can heat. You should remember that the given power rating usually refers to the best possible conditions, so you should take care to purchase a heater that is a little more powerful than you actually need. This will allow for any draughts or poor insulation too.Types-Of-Garage-Heaters

Smaller garages would benefit the most from a radiant or infrared heater. These kinds of heater work best in smaller spaces and because they heat objects rather than air, they don’t really lose heat to ventilation ducts or draughts. You could also purchase a medium sized fan-forced heater for smaller garage spaces too. A 1.5kw fan-forced heater would be better for smaller garages, but if you have a larger space, you should consider purchasing a heater of around 4,000 – 5,000 watts.

Remember to consider the height of your ceiling. If you have a garage with a particularly tall ceiling, you will certainly need a more powerful heater.


Fixed or Portable Garage Heaters

best-garage-heaterWhen you purchase a garage heater, you should know whether it would stay in the same place all the time or not. If you want a heater that you can take with you from one workshop to another, or even if you simply want to move it around the garage, you should consider purchasing a portable heater. These can be easily transported from one location to another and you simply need to plug them into an electrical outlet. If you want true portability with freedom from electrical plugs, you could even choose a fuelled heater instead.

If you don’t need to move the heater, you really should think about getting a fixed heater. These are wired into your electrical circuit and fixed in place, usually higher up, but they can be fixed closer to the floor if you wish. There are many benefits to choosing a fixed heater as you won’t need to worry about finding somewhere safe to stand it, you can’t accidentally knock it over and you can have more space in your garage, especially if it is fixed higher up.


Garage Heater’s Safety Features

When you purchase your garage heater, you should be sure that there would be enough safety features to keep you safe whilst you are working.

  • Tip Over Switch

    – It’s not uncommon for things to get knocked over when you are working in the garage, so getting a heater that has a tip over switch is essential. If the heater is knocked over, it will automatically turn itself off.

  • Overheat Protection

    – As you’ll have the heater on for prolonged amounts of time, it’s likely that every so often, it will become too hot to function. Overheat protection will ensure that the heater turns itself off to protect itself from high temperatures causing damage to any of the heater’s internal parts.

  • Cool-Touch

    – When you have a heater that is on a table or floor, the last thing that you want is for it to get too hot to the touch. Whether there are pets, children or even adults who aren’t thinking that the surface of the heater may be hot, heaters that get hot whilst they are in operation are dangerous. Look out for cool-touch heaters for maximum safety.


Other Features

When you buy your garage heater, you’ll want to ensure that it comes with all the features that you could possibly need. When you buy a heater, the more customizable it is the better, as you’ll get the best possible use out of it. If you have a very basic heart, you’ll have problems like only having one heat setting and the heat could also be directed in the wrong way so that you don’t even benefit from the heat output.

  • Adjustable Louvers – In order to let you direct the heat to where you want it to go, you should look out for a garage heater that has adjustable louvers.
  • Power Cord Length – When you get a garage heater, you should ensure that it comes with a long enough power cord to allow you to place it wherever you need to in your garage. It can be difficult to find an extension lead that is safe to use with high power output heaters so it is especially important that the power cord that comes with the heater is long enough.
  • Carry Handle – If you are choosing a garage heater that is portable, you should ensure that it comes with a carry handle to allow you to pick it up and move it with ease. Although it is not an essential feature, it will make things easier for you.
  • Wheels – Wheels and castors are useful to have a garage heater, as they will allow you to move the heater without the need to lift it. As garage heaters need to be more powerful than other types of heater, they are often heavier with larger elements. Lifting the heater can be bad for your back, so being able to wheel it on casters is a much better option.


Secrets of Heating Your Garage Safely and Efficiently

Radiant-Garage-Heater-PhotosWhether you want to use your garage to fix your car in the winter, or if you simply want to use your garage as an exercise room or gym, You will need some way of making it warmer in the colder months. This is a short guide will give you some advice on keeping your garage warm whilst observing important safety rules.

First of all, you should consider I fixed heater for your garage. Portable heaters can be very dangerous as they are easy to take over and often use flammable fuels.

Some of the best kinds of garage heaters include vent-free, sealed combustion and electric radiant ceiling panels. You should try to avoid using lovely fun style heaters, as they tend to be a little less capable of heating largest spaces.

You should try to position your heater away from the floor or any work surfaces that you are going to be using. A freestanding heater is probably not the best idea as this is likely to get in the way of your exit route or it could be knocked over. This is especially likely if it is on a table top. Instead, you should mount your heater on the wall all the ceiling. Many garage heaters allow you to direct heat as you need to. A good idea is to ensure that their heat flow is pointing towards the center of the garage, or towards any workbench area where you may be working. This will mean that you will get the maximum benefit from the heater.

A radiant panel may be a good idea too, as these can warm up your garage and help it to stay warmer for longer. They do take a little while to heat up so you will need to be patient.


Garage Heating Tips

In order to keep your garage toasty and warm throughout the winter months, you’ll need to ensure that it is adequately heated. Often, the first thing that most people may think of when they consider heating their garage is simply purchasing a garage heater. Whilst this will provide some heat, there are a few other things that you could do to help your garage to stay warm.

  1. Insulate – the first thing that you’ll need to do is prevent any heat from escaping from the garage. Garages are not built to be warm, so adding insulation will ensure that there is no draught.

Use a high-quality type of insulation on the walls and the ceiling.
  2. Choose the right heater – when you choose the heater for your garage, you should ensure that it is going to be effective in heating up your garage space.

If you are thinking of using things like spray paints or gasoline in your garage area, then it is advisable that you don’t use a propane garage heater.

When you use a propane heater in your garage, you don’t necessarily need to keep the propane cylinder outside. Some propane tanks can be used indoors, although these do tend to be the ones that have smaller propane tanks. If you need a larger tank, then it is likely that you will indeed need to keep that outside.

Even though you can use a propane heater in your garage, you should make sure that you look at all the other options before you make your purchase. There are plenty of heaters that are actually designed for use in the garage. If you have an electric supply, for example, you’ll probably get better results and more energy efficient heating from an electric garage heater.


Does an Electric Garage Heater Have to be Hardwired?

If you are purchasing an electric garage heater for heating your workspace, you should ensure that it is being installed correctly. It is difficult to say for certain whether or not your garage heater should or should not be hardwired into your electric supply. That’s all depends on the model of heater that you purchase. Some of these garage heaters are intended for permanent use in the same place. Those units are usually hardwired into your electric supply. On the other hand, there are other units that are designed for you to plug them into an outlet. Although you will get the same kind of heat from both kinds of Peter, the hardwired garage space heaters require installation by a certified electrician.

You should check the item description when you are purchasing your heater to see whether it will need to be installed directly into your electric supply, or whether you can simply plug it into an outlet. Before you have the heater installed, it is a good idea to have an electrician check the voltage output of your electric supply. Lots of garages are fitted with a standard high-voltage electric supply but some of them use the lower voltage that is required for a lighting circuit. It would be dangerous to connect a heater to this kind of circuit.
