Those winter days in the garage, workshop or shed can be brutal. The dropping temperatures mean finding the right electric garage heater is critical. It can be uncomfortable to have to spend your working day in a cold environment, especially if your work requires a lot of manual labour, reducing productivity more than you think.
It can be hard to work out which electric heater is right for your workspace. Garages, sheds, and workshops all vary in size and characteristics, meaning it isn’t always a one-size-fits-all job. This guide will outline what to look for in an electric garage heater for your space and why we always opt for PTC heaters.

What To Look For In An Electric Garage Heater
Below, we will outline the key aspects to consider when choosing your electric garage heater and what you should look for in each model.
Heat Output For Your Space
Assess your workspace and determine the heating needs of your area. Small sheds are likely to have different needs compared to a large garage or workshop. Consider elements of your workspace such as insulation, ceiling height and draughts that might impact heater performance.
Fast Warm-Up Time
On those cold winter mornings when you’ve just got in, you want an electric garage heater that warms up quickly. Manufacturers will state the speed in which they warm up and start emitting hot air. Some models perform better than others, such as a PTC heater, thanks to their design.
Portability And Placement
Being able to move your electric heater and place it next to you is an important factor. Consider portability and placement in your workspace before buying. In large spaces with multiple rooms or areas, you don’t need to heat all of it, just the bit you’re in.
Safety Features
Safety features are another aspect that gets overlooked. Look for electric heaters that have safety measures in place to prevent overheating and support stable operation.
Energy Efficiency
Electric heaters can draw a lot of power if not efficiently using it, which is why they can sometimes cost more in the long run than first anticipated. Look into the heater’s heat delivery system and how it maintains temperature to avoid wasting output.
Build Quality For Working Environments
In a working environment, any bit of kit or machinery that isn’t built to last will quickly fall apart. In a garage, there are plenty of scenarios where a heater could become damaged, so they need to be built well and with durability in mind.
Why Electric Heaters Work Well In Garages, Workshops And Sheds
Electric heaters are the go-to heating solution for garages, workshops and sheds across the country. This is for many reasons. They are not only very simple to operate, just plug in and turn on, but they don’t require topping up with fuel like a diesel-powered version. As a result, there are no fumes created as a byproduct, so ventilation isn’t required.
They are perfectly suited for enclosed workspaces, only when used correctly and with safety in mind. The cleaner and more convenient heating solution.
Why A PTC Heater Is Often The Best Choice
Our choice of electric garage heater is any PTC model, like our Airrex Heat 2000, for a range of reasons. One of the biggest draws to a PTC model is the fact that they self-regulate as they warm up, meaning energy efficiency is a big plus.
Thanks to their design, they maintain a more consistent temperature compared to a typical electric fan heater. This design also means the risk of overheating is reduced significantly. For many workshops, garages and sheds, they need dependable heat that consistently delivers heat, which is why we suggest a PTC heater.
If you want quick, reliable heat with added reassurance, a PTC heater is well worth considering
PTC Heater vs Standard Fan Heater
When choosing an electric garage heater, it is worth understanding how a PTC heater compares with a standard fan heater.
A standard fan heater works by blowing air over a heating element to warm the space. It could be the ideal option for quick heat in smaller areas or for short periods of use. For heavier day-to-day use in garages, workshops, and sheds, it may not always offer the same level of control or steady performance.
A PTC heater is designed to give a more controlled heat output. As the ceramic element warms up, it helps regulate the heater’s temperature, reducing the chance of overheating and supporting more consistent performance. This makes it a practical choice for working environments where reliable heat matters.
For workshops, garages, and sheds used through winter, a PTC heater is often the more suitable option. It provides effective heat, practical safety benefits, and dependable performance for regular use.
How To Choose The Right Size Heater
When it comes to choosing the right size heater for your space, it is important to remember the size and condition of your space. For smaller workspaces, like sheds and small workshops, you do not require more than a 2kW electric heater to heat your space. Larger spaces may require a 3kW heater to effectively heat the whole space.
Choosing The Best Electric Garage Heater for You
The ideal electric garage heater depends on the size of your space, the warmth required and how often it will be in use. If you can clearly define these, you have all the information to help you choose your new electric heater. Remember to consider safety features and durability alongside heating power.
