5 Best Garage Heaters of 2025

Having done a lot of research into the best garage heaters, I put the Honeywell Heavy Duty Heater CZ 2104EV to the test to see if it was a good option for most households.

I must admit, I absolutely love the appearance of this heater. It’s got this industrial charm to it. It looks a bit retro, yet its grey coating brings makes it current. It’s value is in its simplicity as well. Two simple knobs to select the temperature and setting, and some lights to indicate when its in use.

The only bit you have to figure out for yourself is that the fan setting knob needs pushing in before you can select which heat setting you want. At first I turned it on, and wondered why nothing was happening, but quickly sussed it out!

From my testing it took just under 20 minutes to heat my old man’s single garage from 9°c to 20°c – that is pretty respectable in my opinion. Perfect time to go grab a coffee! The only downside I suppose is that it’s got some noise behind it. But considering we’re usually in the garage testing out power tools, a little fan noise isn’t really of great concern to me!

Again, the charm of this garage heater is in its simplicity. As such, there aren’t many high-tech features to write home about! It’s got a fan setting which can be useful in the summer. It’s also got a ‘frostwatch’ function that automatically starts the heater when the room temperature drops below 5°C which can be quite handy too. 

Onto the safety features. This heater has a sturdy construction, a heat insulated handle and overheat protection. The child safeguard switch prevents children from tampering with the heater, while the tip over safety switch ensures the heater turns off instantly if it’s accidentally knocked over.

In terms of value for money, this heater can’t really be faulted. It’s very fairly priced and can perform exactly as most people need it to. It looks the part and can heat your garage in under 20 minutes. Job done!

A popular garage heater well worth a mention is the Draper 92967 PTC Electric Heater. This heater uses a ceramic heating element and PTC technology to warm spaces up to 20 m² in size. It’s a great option for small garages. 

Style-wise, this heater may not win many awards, but if you’re looking for an effective garage heater, there’s a lot to love. It’s neat, compact and stable, with a reliable stainless steel stand. It weighs just 1.91 kg, so it’s easy to move around the garage if needed. The 1.5m cable, although arguably a little short, is good quality.  

Like all the garage heaters I’ve mentioned, this heater boasts a range of settings so you can heat your garage according to your specifications. There are 3 settings; fan, low and high. The fan setting can be used in the summer months to cool your garage, while the 1000W and 2000W modes can be easily switched between depending on the temperature outside. 

This heater comes with an adjustable thermostat to help maintain a constant room temperature. If the temperature plummets overnight, this heater will automatically switch on and heat the room to your desired temperature, protecting equipment, machinery and more from frost or frozen temperatures. 

Safety features include dual overheat safety protection. The unit will instantly switch off if it detects that it’s gotten too hot. The stable base and reliable construction also add to the safety. 

Finally, this heater offers great value for money. It can heat rooms up to 20m² in size, and it’s very good quality. On the lower power setting, this heater doesn’t cost a lot to run, making it a good option for taking the edge off small, chilly garages. 

If you’re looking for a small, portable table top heater for your garage, the ANSIO Ceramic Electric Heater is a great option. This heater is extremely compact, yet it produces a good amount of heat given the size. 

This portable heater has a neat black design and is packed full of features that make it easy to warm small rooms and garages. It can be placed on tables or it can also be sat on the floor. 

This heater offers good performance especially given the small size. There’s a PTC heating element for faster, efficient heating, while there’s also 2 power options. The low power mode at 1200W will take the edge off your garage on chilly days, while the high power mode at 2000W is perfect for warming your space when the temperature drops below freezing.

A welcome extra feature is the adjustable thermostat. The heater will automatically turn off when the desired temperature is reached, saving you power and helping to maintain a consistent temperature. 

Onto the safety features. This ceramic heater is safe to use thanks to its sturdy and robust build. The overheat and tip over protection means it can be turned on even when pets or children are in the vicinity. If the temperature is too high, the thermostat will automatically turn the heater off, while the safety tip over switch automatically cuts the power off if the heater is knocked. 

The only real downsides to this heater seem to be the length of cable and the noise level. As it uses a PTC heating element, this heater is slightly noisier than regular fan heaters. It also shouldn’t be used with an extension lead, which will limit some users, as the included cable is fairly short. 

If you’re looking for a super compact and lightweight option, this is one of the best garage heaters if you want something highly portable.

A great option for those who don’t want their electricity bill to skyrocket, the Igenix IG9514 Portable Halogen Heater offers a cost-effective and economical way to bring some extra warmth to your garage. As a halogen heater, this model provides heat almost instantly, and there’s no nasty gases or emissions released. 

There are three power settings to choose from, depending on the size of your garage: 400W, 800W and 1200W. This means the energy output can also be controlled easily. For those who like to work in the garage, this heater is very quiet so won’t disturb you. It also produces light, so can be used to illuminate your garage if there’s not a lot of natural light. 

In general, this heater can make a difference in most garages in just a few minutes. It heats instantly, while the oscillating function ensures everyone in your garage can benefit from its warmth. Of course, it’s worth noting that it’s a halogen heater, so it only warms people and material, instead of the garage air. If you’re not standing in front of the heater, you’re unlikely to see much benefit. 

Design-wise, this heater is robust, stable and well-balanced. It weighs just over 2 kg and the handle used to transport it is heat resistant and strong. This heater can be moved around your garage even while switched on with no concerns that you’ll burn your hands. 

In terms of safety, there’s a cut-out safety tip over switch which prevents injury if the heater is suddenly knocked. This makes it safe for areas regularly used by children or pets. The heat resistant handle prevents burns if the heater is lifted while switched on.

The Igenix Portable Halogen Heater is great value for money primarily down to its low cost to run and ease of use. The only disadvantages seem to be the length of the power cable, which is a little short.

The Modern Life Diesel Paraffin Space Heater is different to others on my list as it uses paraffin oil to heat large spaces. Whilst you may think this makes it harder to use than standard heaters, it’s actually relatively easy. This heater has been specifically designed with ease of use in mind. It’s very simple to get set up and works well in large spaces.

This space heater is well-made and good quality. It has a stainless steel combustion chamber which is very durable, while it’s easy to move around using the castor wheels. You’ll be thankful for the wheels, as this heater weighs over 20kg! Unlike others on the market, it can’t be easily picked up and placed in a different location, but the wheels allow you to drag it across hard ground. 

This heater performs very well in large garages. It has an air output of 720 m³/h which allows it to heat rooms up to 350m² in size. It’s energy efficient too, with a fuel consumption of around 2.5 kg per hour. The tank capacity is 38L and this needs infrequency filling. It runs on either diesel oil, kerosene or paraffin. 

In terms of extra features, this heater ticks a lot of boxes. First of all, there’s an adjustable thermostat so you can set your ideal room temperature. There’s also an easy to read temperature display and control. For very specific garage heating needs, this model is perfect. 

This heater is also very safe. There’s a flame sensor and cut-off protection if it overheats. It’s also IP24 rated which means it’s splash proof – never a bad attribute when used in a garage or shed. 

A couple of disadvantages to note. Firstly, this heater using a fan that can be quite noisy. If you’re looking for a quiet heater, this probably isn’t the best choice. Secondly, a power outlet is required to power the fan and display, so although gas powered, you’ll still need access to electricity. 

If you’ve got a large double garage and you’re after an effective industrial-size heater, the Modern Life Diesel Paraffin Space Heater is a fantastic choice.
