What ever you choose to do in your garage, one problem that everyone seems to have, specially in winter is the need for a little warmth to make working in your garage more comfortable. 

To understand what heater you need for you garage, you will have to accustom yourself with the basic functions and different types of garage heaters available. That way, you will be able to pick the best garage heater for your garage space. 

There are two main types of garage heaters, the first are electric heaters of which we found the space heater types very good and are by far the most popular due to ease of use and the second type are gas powered heaters.

After hours of intensive research and comparing over 20 models, we narrowed our search down to just 6 garage heaters which we found to be very effective at warming a standard sized garage or larger up quickly and efficiently.

Before we go into these heaters in more detail we would like to point out that the heater we think is the best garage heater for most people is the Kingavon 3KW Industrial Heater as it can heat up an impressive 60 square meters quickly, has 3 adjustable heat setting which makes it ideal as you can turn it down if needed and it comes at an incredibly good price.

Garage Heater Buyers Guide

When looking for a good garage heater you have to consider a few factors first. There is a countless number of customers who have returned bought goods because they did not have the right specifications. You will find that the differences are minimal but they can affect some more than others. Be sure to look for a unit that has a stable construction if using in a working enviroment so this means it should have a metal case and secondly, an effective heater power output that can sustain heat production, we found that most people would need a 3kw model to effectually heat a garage.

If you read further, you will get to understand and compare between the different types if heaters but we strongly recommend electric blow heaters with a fan (also known as space heaters) for most people

Types of good heaters

  • Electric Space Heaters - These are usually cheap to run since they have active thermostats. Once the preferred temperature is achieved the unit stops producing heat. They usually include fans that are used to propel the warm air around the room. They are usually easy to work with an install since their size in not too heavy as a good model will only weigh around 3-4kg. They are however limited to use when there is no electricity which is a problem for some people. They, however, are good for the environment since they have no emissions and are very easy to use, simply plug in and turn it on.
  • Infrared/radiant heaters - We put these two kinds together because they have similar ways of heating up space. They heat the direct objects that around them. There is a high chance that everything that is out of the units direct heating radius will be cold. If you are looking to heat one specific area such as a work station you can rely on these forms of garage heaters and they are economical.
  • Gas garage heaters - Under this category, we include propane or natural gas the same type used for gas BBQ's and patio heaters that you can buy in bottles in garden centres and at local garages. These are very effective in heating the air around your space. You are guaranteed that they will warm larger spaces effectively. They are low maintenance units once you have the fuel in place. They, however, need physical monitoring so as to control the temperature . These kinds of heaters are appropriate for greenhouse uses. The carbon dioxide and vapour help with plant growth. They are not encouraged for indoor use due to the emissions.

Best Heater For Large Garages

Kingavon Garden mile 10Kw Gas Industrial Space Electric Fan Assisted Heaters Review

Kingavon Garden mile 10Kw Gas Industrial Space Electric Fan Assisted Heaters

This title goes to the Kingavon 10Kw Industrial Space Electric Fan Assisted Heater. This is because of the fact that it can heat up large rooms quickly and efficiently.

This is a heater that can handle heating up even he largest garages. We also love the design and the fact that it is economical to run. 

Overall if you got a very large garage then this is probably the best option as its 3 times more powerful than our 'Best Pick' at a very impressive 10kw.

What is the amount of space that you want to heat

The space that needs heating will determine the size of the unit. A smaller unit will do well covering small areas. Larger units consume more electricity and space. If you have a large garage, you have to purchase a sizeable unit. You also have to put into consideration the insulation of the space. If your space is insulated, then you have no need for a unit with a large heater since the heat produced is contained. If not, you need a unit that can keep up with constant heat production. We recommend insulating your garage as much as possible as this means the heaters are more efficient as less heat is loss.

Movable or Permanent unit

Depending on your requirements and the size of the garage, you may need a movable or a permanent unit. There are units that come with brackets that can be used to mount them for those who need permanence. For those who would like to move a unit around, you need features like wheels and freestanding feet. That way no matter the place you put the unit, it will stand in accordance. You can decide to have a technician hard wire your heating system with compatible models. The choice is yours. Most people a small but powerful 3kw heater is more then sufficient while still be light weight enough to move around if needed.

Look for safety features

Safety is paramount when working on anything. You do not want to spend money on equipment that is possibly a fire hazard. When looking for a safe unit, you need features like a tip-over switch and at the very least overheating prevention mechanisms. A tip-over switch allows the unit to switch off automatically if the unit is knocked over by accident. Features like cool-to-touch are important if you have curious kids lingering around. Be sure to look at any safety recommendations set by the manufacturer so as to avoid any mishaps. This goes without saying, never leave children unattended with the heater on.

Consider price and warranty of the unit


Your spending power will determine the level of quality you will receive. We know that the cheapest is not necessarily the best and neither are the pricey products. Work with a budget to help you narrow down the range of products you can access. You have to be sure that the product provides value for money. That is why we recommend that you compare the features offered against the price. We found that if you allow around £50 budget this will be enough to get a good garage heater with more than enough heat output for most people.


Make sure it comes with a warranty, all products heaters should include a least 12 months warranty with some more expensive models including 2 years warranty. The longer the warranty the better for you.


Kingavon 3 kW Industrial Heater Review


Kingavon 3 kW Industrial Garage Heater Review

Kingavon 3 kW Industrial Garage Heater

The Kingavon 3 kW Industrial Heater is probably the best heater of its type we have seen. Its dark colour can fit in most domestic surroundings and you can tell from the minute you see this heater that its the 'real deal' when it comes to a garage heater, robust and very well made with its metal casing.

This unit is perfect for warming up standard sized garages, workshops and even sheds. It has a maximum output of 3000 watts and  is rated at 3kw which is as high as you can get for a electric heater with a standard 3 pin plug. If you go any higher your then on 3 phase power which most people do not have in their garages. However this heater can efficiently heat up to 60 meters squared with ease which is more than enough for most garages.

This unit is also fitted with an adjustable thermostat, all though the thermostat won’t allow you to set exact temperature, it will allow you to select between the available 3 heat settings.

The heater itself is fitted with a fan to make sure that the hot air is circulated effectively and efficiently. The twin heating element ensures that fast regular heat is produced straight away so it almost instantly starts producing heat which makes it more efficient.

The unit is also designed with a handle that facilitates easy movement and it compact shape means it easy to store. The handle is ergonomically designed to make certain that the users hands are not damaged.

We really like the metal casing which provides durability and protection from random impacts, some models that are mainly manufactured from plastic are easily broken so its nice to see this model has a full metal casing.

The dimensions provided are as follows, L20 x W22 x H33.5cm (like we said compact). All the basic safety functions like thermal protection and overload mechanism have been fitted which is extra reassurance. Finally of has a rating IP44 which means that it is safe for use and has passed uk safety standards.


  • Heats up to an impressive 60 meters squared of space effectively.
  • Features 3 adjustable heat settings with thermostat control.
  • Powerful 3kw heater with twin heating elements.
  • Full metal case for extra durability and heater overload protection.


  • No problems to report but not recommended for very large garages unless you use 2.

Final conclusion

The Kingavon 3 kW Industrial Heater is perfect as its very effective at heating up areas fast, has some great features including the thermostat and 3 heat setting and best of all comes at an affordable price.

We really like the build quality and the metal casing that protects the heater. The double heating element is also a great feature not usually found on similar models.

We love its simple and easy interface that allows people to use the unit with ease even if you never used one in your life. Simply plug in and switch it on then set the power setting 1, 2  or 3, 3 being the highest setting.

We have 3 very similar models in this review but we think this model has the edge as it has that extra kw of power which means it does give off slightly more heat. The only way we would maybe recommend the Honeywell or small Kingavon model over this is if you have a particular small garage or workshop where the smaller 2kw and 2.5kw would be sufficient.

However, its better to have more heat with the option to turn it down than it is to not have enough heater after you have purchased the product. Taking all this into account, we felt it only right that we named this garage heater our 'Best Pick' winner. It really is a brilliant little garage heater.

If you have a very large garage or workshop then your next best choice would be a gas space heater such as the Kingavon Garden Mile Space Heater which we review further down.

Sealey LP14 Propane Heater Review

Sealey LP14 Propane Heater For Garage Review

Sealey LP14 Propane Heater For Garage

The Sealey LP14 Propane Heater is a great little great little heater and a great alternative to those who either don't have electric or prefer to use gas. The propane based unit has the ability to run for longer hours depending on the capacity of the propane tank which in turn would probably lower the running cost even more as you can invest in larger bottles of gas. The ceramic plaque type heater is safe to use around the garage, workshop or even shed.

The maximum output recorded for this unit is 15,354 Btu per hour, we think that on low it would probably last around 80 hours from a 13KG bottle and 13 on full. You can control the rate of heat production by controlling the regulator which means you can turn it down to the lowest setting once you got the room to a suitable temperature. You have to look at the space and calculate if the rate of output will work for you. It should however easly heat a double sized garage to give you an idea.

It does come with a stand to make certain that the unit remains freestanding. We do like the steel construction as its very durable.

It comes with a 150cm long hose to make sure that you have enough reach and a regular to attach it straight to the gas bottle.

Finally it comes with a one year warranty for full peace of mind but being how simple these types of heaters are its unlikely there would be any problems.


  • Stable construction.
  • Very effective at heating spaces.
  • Do not need electric to run.
  • 1 year warranty for full peace of mind.


  • Not suitable for use in the home.
  • The instructions could do with being clearer.

Final conclusion

The Sealey LP14 9,200-17,000Btu/hr Propane Heater is perfect for commercial applications as well as for garages and workshops.

The rate of output is high enough to easily heat a double garage or fairly large workshop. You will have to purchase another propane bottle from time to time when the supplies run low which is the only real disadvantage.

The unit is very easy to use once you have attached the gas bottle so you will not have a hard time operating it. For the price that you get it at, it is not particular expensive, probably around the same price range of most electric heaters including our 'best pick'. This is a great option for someone looking for a gas heater to heat their garage and as there no fan fitted you don't need to connect to an electricity supply which means it can  be placed nearly anywhere you want.

Overall a great little heater that gives off a lot of heat.

Kingavon 10Kw Industrial Space Electric Fan Assisted Heater Review

Best Heater For a Larger Garage or Workshop

Kingavon Garden mile 10Kw Gas Industrial Space Electric Fan Assisted Heaters Review

Kingavon Garden mile 10Kw Gas Industrial Space Electric Fan Assisted Heaters

This Kingavon 10Kw Industrial Space Electric Fan Assisted Heater is another propane model but one designed for larger garages and heats the space up much quicker because of the electric fan it incorporates. The design of the model makes it look fantastic like something from a sci-fi movie. This propane based garage heater has a maximum 700m bar output of 320m³ per hour which will heat up a 200m2 garage.  

These units are strong enough to cater to industrial functions that are not necessarily stretched. This mighty machine is economical to run as it is estimated to consume 0.73KG in a given hour making it very affordable to run.

To make certain that you have the perfect reach a long 150cm gas hose have been provided so you have plenty of reach for even larger sized gas bottles.

What we like about this heater is that can run on LPG gas or propane gas and comes with a regulator that you can use. Not all models come with a regulator and this would be an extra expense. If you have a large area to heat, this is the unit that you can rely on.

The unit has basic heat safety features installed which is obviously a must.

What his model does like is a thermostat so you cannot set it to a certain temperature, you would need to manually turn it off if it gets to warm. 


  • Perfect for larger garages and workshops where electric heaters ideal.
  • It is of a good construction and it is stable.
  • Fair price for the features provided.
  • It runs with little noise.


  • Not recommended for use in unventilated areas.
  • No thermostat control.
  • Needs to be plugged into a plug socket to power the fan as well as connected to a gas bottle.

Final conclusion

The Kingavon 10Kw Industrial Space Heater is for great for them big areas that still require ventilation or larger garages the smaller electric heater want be effective in.

The fact that it can consume small amounts of gas per hour makes it rather economical to run.  The only real downside is that you will have to purchase the gas separately which will be an added cost for you to consider and extra work.

For industrial and commercial functions, this unit is perfect. Smaller spaces should look for a smaller unit as it does kick off a lot of heat which would be to much for small garages.

Honeywell Heavy Duty Heater Review

Best Heater For a Small Garage

Honeywell Heavy Duty Garage Heater Review

Honeywell Heavy Duty Garage Heater

The Honeywell Heavy Duty 2.5kw Heater is made of durable metal and is another very good heater for a small garage or workshop. If you look at the whole construction of the unit you will understand why it is called a heavy duty heater.

One feature this model does have which our 'Best Pick' does not is the frost watch function. If the temperatures happened to fall below 5 degrees, the unit will re-activate itself keeping the room at a reasonable temperature at all time. This feature cannot be found on all models that you meet in the market. Its also worth noting that this model could also double as a greenhouse heater because of this feature.

To ensure that all the warm air is evenly dispersed, the unit has a fan. This fan can also be used independently as a cool fan on those hot days where the sun is restless. Back to what we really need the fan for, it ensures the heater can effectively heat up 30m². In comparison our 'Best Pick' can heat double this amount of space which is why this heater is better for smaller garages. However this may be enough for some people who do only have a small workshop or shed to heat.

A thermostat has been installed so that you have control over the temperature and it has two heat setting. A tip over switch makes the unit all the safer to use around children and pets or in case you knock it over by accident. If the unit falls it switches off automatically. So that the safety measures are optimum, an overload prevention mechanism has been installed.

Just in case you find something wrong with the unit, you can take advantage of the 3 year warranty offered which is 2 years more than our 'Best Pick'. We struggled to find a heater that came with a warranty as long so 3 years is very impressive.


  • Well-constructed metal casing.
  • 2 heat selling with thermostatic control.
  • Frost watch function that keep the room above 5 degrees.
  • Fast heat circulation with the powerful fan
  • 3 year warranty for full peace of mind.


  • Is limited to warming small spaces.

Final conclusion

The Honeywell Heavy Duty Heater is a really good heater is you have a smaller garage or workshop smaller than 30m2.

Larger rooms would need more than one unit to effectively heat the space which means that our 'Best Pick' would be a better choice in this situation as it will heat double the space.

We really like the strong metal casing which makes it adaptable to the workshop environment.

Overall this is a very good heater but do make sure you garage or workshop is less than 30m2 first as it does retail at around the same price as our 'Best Pick'. What we do like about this model though is the frost watch, this could be handy if you have a washing machine, fridge etc in the garage and want to keep the temperature above 5 degrees which will stop pipes freezing etc.

Kingavon BB-FH207 Industrial Heater Review

The Kingavon BB-FH207 Industrial Heater Review

The Kingavon BB-FH207 Industrial Heater

The Kingavon BB-FH207 Industrial Heater is another good product but only really suitable for small garages or workshops as its only 2kw. This brightly coloured unit is hard to miss. 

To control the temperature settings, you will find that you have 3 heat setting. You can select between the 650 watt,1300 watts or 2000 watts.  The 650w heat setting though its actually cold.

The unit also has received an IP44 rating making it safer to use in environments with high moisture levels.

Like most models, it also has a fan to make sure that the warm air is circulated around the space. It also features a simple thermostat that is adjustable to aid you in your need to control the heat.

This model also gives off no emissions and no smells so is safe to use in sealed areas as no ventilation is needed. For a small garage or shed, this unit will do just fine. However anything larger and you will not feel the benefit.


  • Nice and robust design.
  • Affordable price.
  • Easy to use with 3 heat setting and a thermostat.
  • IP44 rated.


  • Can only heat small places.

Final conclusion

The Kingavon BB-FH207 Industrial Heater is dependable for heating small spaces. You will realise that the unit cannot support heating larger rooms due to its lower powered design.

What you pay for is what you get. For a unit in this price range, it is not a bad product. If you need something with more power you would be better investing the extra money in a more powerful unit. For those who do not want to spend much and still need to warm up a small space, this is the unit for you.

Overall a nice little heater which is more that suitable for small sheds.

Hylite HHT205 500mm Slimline Eco Heater Review

Hylite HHT205 500mm Slimline Eco Heater Review

Hylite HHT205 500mm Slimline Eco Heater

The Hylite HHT205 500mm Slimline Eco Heater is a lightweight tube heater which is more designed for preventing dampness, condensation and keeping the room above freezing. This means its not really designed to make the room what you would describe as room temperature. 

The tube heater is fitted with a thermostat that will enable you to control how hot it gets in your space. The unit has a slim design that is easy to store and move around. The size just makes it convenient for people with small spaces and you can use the included brackets to mount it to the wall if need.

A 1.5 meter cable has been provided to give you some wiggle room when moving it around. The unit has a 1P44 rating which indicates that it is safe to use in high moisture content areas if needed without being damaged by any moisture. Without the protection, the unit would succumb to water damage.

When the maximum temperatures are reached, the cut-out becomes active to prevent the unit from overheating and to help keep the room at a consistent temperature.


  • ?Designed for preventing dampness, condensation and keeping the garage or shed above freezing.
  • At 55w its a very low cost heater.
  • Built in thermostat to control temperature
  • IP44 rating for water resistance.
  • Can be mounted or left freestanding.


  • Can only cover small spaces.
  • Thermostat needs more visual aids for accurate temperature setting.
  • Needs a guard that is bought separately.

Final conclusion

The Hylite HHT205 500mm Slimline Eco Heater is not designed providing alot of heat but more as a way of preventing dampness, condensation and keeping the garage or shed above freezing. 

However surprisingly It will get a small room to a reasonable temperature as long as your room is small or you have a few units. We also like that this unit can be mounted making it convenient for those who are pressed for space. You have to be sure of the performance before purchasing this unit or you will be highly disappointed.

This is an affordable unit and you can expect the available features to reflect great performance. The unit is fitted with a seven-step thermostat but you cannot determine the actual temperature which is a shame. Those looking for a cheap and moderately heating unit can keep this one on their shopping list, perhaps ideal for a garage where it might be attached to your house and not get quit as cold as a stand alone garage.

Our Final Conclusion

We looked at other 20 different heaters we though would be suitable for using in a garage. When we started our research and found that there are a lot of very under powered heaters on the market that are simply not up to the job. You have to remember garages are not like our homes are are not as well insulated, if insulated at all.

After our research we narrowed our search down to just 6 garage heaters that made in onto our review which were the best garage heaters depending on what size garage you have.

Below is a quickly summary of some of our favourite garage heaters.

Overall it really is hard to find a better electric garage heater.

After comparing all the features and specifications with other models its simply a clear winner which is why it was awarded our 'Best Pick'.
