Garden Room Heating: The Best 10 Options

At this stage in our society, there are over a dozen methods for heating garden rooms. So, the only issue you will face is choosing the right one for your budget, desired aesthetics and values, especially regarding environmental-friendliness. This article will help with that.

We’ve already started by narrowing down the best ten garden room heating methods. Now, we will take a brief look at each of them. Hopefully, this will help you find your preferred way to heat your garden room.

Electric Radiator

Let’s start with a modern and highly efficient method for heating a garden room. Electric radiators are incredible. They are just like regular gas radiators, but lower maintenance, cost-effective and energy-efficient. They also have many control options, often with remote control for timers and thermostats.

The only major disadvantage of electric radiators is slow heat distribution. It takes a while for heat to spread evenly throughout the garden room. However, coverage is good once the radiator is up and running. 

Besides, it’s easy to fix the issue of heat distribution speed. You can simply preheat the garden room ahead of time. So, don’t let this little hiccup stop you from choosing electric radiators. They are one of the best garden room heating methods on the market.

Oil-Filled Radiator

This is another excellent alternative to traditional gas radiators. In an oil-filled radiator, oil is heated. The hot oil heats the room. This means heating can continue even after you switch off the radiator. Heating will continue until the oil finally cools down. 

Oil-filled radiators share some of the pros and cons of their electric counterpart. They are both energy- and cost-efficient and slow with heat distribution. There are other benefits, too. 

Oil-filled radiators are freestanding and portable. Therefore, they don’t take up much room and you can move them at will. You can even remove them for storage when not in use, like in summer. All in all, oil-filled radiators have the traits of a good garden room heating system. 

Panel Heater (Aka Electric Convector Heater)

There are many good reasons to use a convector heater for heating a garden room. Examples included relatively affordable installation, lots of control options, remote Wi-Fi control, and fast start-up. You also get to choose between a wall-mounted or free-standing heater. Both have different impacts on aesthetics and space.

However, there are also good reasons to avoid this garden room heating method. Panel heaters cause dry air and become fire hazards upon contact with flammable materials. They also have limited coverage. Therefore, you have to position panel heaters strategically.

Underfloor Heating

Underfloor heating is a popular method for heating a garden room. However, many people prefer to use it as a secondary heating system. Reasons for this include high installation and operating cost, and slow heat distribution.  

There are positives, too. Examples included energy efficiency, good coverage, versatility, lots of control options, little to no maintenance costs, and space optimisation. However, that last benefit is a double-edged sword. Underfloor heating saves on living space but also takes up floor space. Another issue is installation requires massive disruption of existing flooring. 

There are two types of underfloor heating: wet or dry/electric. Wet underfloor heating has a higher installation cost, lower operating cost and better heat retention. However, both are great for heating a garden room. 

Underfloor Heating

Wood-burning Stove

A wood burner might not be the most eco-friendly way to heat a garden room, but it is definitely one of the most stylish. The classy aesthetic appeal of a wood burner is eternal. Besides, there are many eco-friendly wood-burning stoves and fuels on the market. 

These eco-friendly options are usually referred to as carbon neutral. Examples of such fuels are biomass pellets, compressed wood and eco briquettes. So, you just need to choose a carbon-neutral wood burner that uses eco-friendly fuel. 

A wood-burning stove has good coverage and can work continuously for an extended period. Therefore, it is excellent for garden room heating. The only major con is the cost of installing a flue. Well, that and the effort, money and time required to operate and maintain a wood-burning stone.

Electric Stove

Here is another stylish garden room heating method. Only this one doesn’t have the main con of the last one, environmental friendliness. An electric stove is one of the most environmentally friendly and efficient ways to heat a garden room. There is almost a 100% energy efficiency. Nearly all the electric energy is converted to heat.  

Electric stoves also have more control options, unlike wood burners. They are also lower-maintenance. However, both are best suited for small spaces. Still, both are great for heating garden rooms.

Bottled Gas Heating

The main advantage of this garden room heating method is that you can use it off the grid. You don’t need an electricity or gas line. You simply use bottles or cylinders of natural gas to power the heater.

Bottled gas heating is an efficient and cost-effective way to heat a garden room. However, there are cons. It needs excellent ventilation to stop toxic fumes and water vapour from accumulating in the garden room. The bottles will take up outdoor space and possibly affect aesthetics. A common trick is to conceal them. 

Infrared Heating

Infrared heating is one of the most energy-efficient methods for heating a garden room. That’s because this system doesn’t just heat the entire space indiscriminately. No, it targets subjects (people or things), heating them specifically.

Therefore, only consider this garden room heating method if you want this effect. Then, position the heater strategically to reach whom, what and where you want to heat.  

Solar Powered Heating

Solar energy is also an excellent option for heating a garden room. Once you get over the high installation cost, it’s easy to see the many benefits. This garden room heating method is exceptionally eco-friendly and low maintenance.

However, a solar-powered heating system is only viable in a location with enough sunlight daily. Here is how the system works. Solar energy heats a heating element (fluids housed in tubes), which enters the radiator and radiates heat around the garden room.

Air Conditioner

Air conditioners aren’t just for cooling. You can use them for heating too. This dual functionality presents an advantage over other garden room heating methods. It allows you to kill two birds with one stone. The air conditioner will provide heat in cold months and cool in warm months.

There are cons with using an AC to heat a garden room. Firstly, air conditioners can’t match the output of the other garden room heating methods. Some air conditioners are also noisy and big, although low-noise, compact options are easy to find. Therefore, output and maintenance are the only real issues of using an air conditioner for heating a garden room.


Heating is one of the most important features to add to your garden room. Without it, your garden room could be unusable in the cold months of winter. However, garden room heating can’t function alone in this regard. It has to work alongside garden room insulation.

Insulation will reduce heat loss and thereby reduce your heating needs and costs. So, if your garden room isn’t insulated, now is the time to rectify that. Fortunately, there are also many options for insulating a garden room. We have a great article that will help you find the right one.  

As for now, we hope to have introduced you to enough ways to heat your garden room. Now, you just have to choose one. The choice should be easier when you consider factors like heat output, coverage, installation, operating and maintenance cost, available space, aesthetics and speed.
