At the end of summer, the days can still be very pleasant, but the contrast quickly becomes noticeable as soon as the sun goes down. A terrace that feels comfortable at 6 p.m. can become significantly cooler just one or two hours later, sometimes bringing an outdoor dinner or evening to an early end.
This is precisely when a patio heater becomes particularly useful. The idea is not necessarily to heat an outdoor space like an indoor room, but rather to provide targeted warmth around a table, an outdoor lounge area or beneath a covered terrace.
So, should you install a patio heater as early as the end of summer? Which model should you choose? What power output do you need? Infrared or conventional heating? Hanging or freestanding? Here is everything you need to know to continue enjoying your terrace when the evenings start getting cooler.
Why do evenings suddenly feel much cooler at the end of summer?
From the end of August onwards, the days gradually become shorter. Even when daytime temperatures remain pleasant, the sun sets earlier and temperatures can drop quickly in the evening.
This sensation is even more noticeable when it is windy, when the terrace is exposed or when you remain seated for a long period of time.
The result is familiar: everyone enjoys dinner outside, but ends up going indoors earlier than expected because the air has become too cool.
Yet this time of year can still be extremely pleasant for enjoying the garden. The aim is therefore not necessarily to stop using the terrace, but rather to gradually adapt it to the cooler season.
When does a patio heater actually become useful?
There is no exact temperature at which a patio heater suddenly becomes essential. It depends on individual sensitivity to the cold, wind, humidity and the location of the terrace.
In practice, it becomes particularly useful when daytime temperatures remain pleasant but evenings start to feel cool. This is exactly what frequently happens at the end of summer and the beginning of autumn.
A patio heater can help extend:
- evening meals;
- outdoor drinks;
- evenings with friends;
- time spent in an outdoor lounge area;
- the use of a covered terrace or pergola.
In other words, it is not only useful in the middle of winter. Above all, it can help you gain several additional weeks of comfortable use of your terrace before genuinely cold temperatures arrive.
Why isn't waiting for cold weather necessarily the best strategy?
We often think about patio heaters only when temperatures become genuinely cold. Yet they can be even more enjoyable during the transitional seasons.
When the air is simply cool, a well-positioned heat source may be enough to completely transform the comfort around a table.
Rather than trying to heat a very cold outdoor area, the patio heater simply compensates for the drop in temperature during the evening.
This is precisely what makes the end of summer so interesting: you can continue enjoying bright, pleasant days while remaining comfortable when the temperature falls after sunset.
How does an infrared patio heater work?
Infrared heating works differently from a system designed primarily to heat the surrounding air.
Infrared radiation transfers heat directly to people and surfaces within its effective area. This is particularly useful outdoors, where warm air can quickly disperse.
This technology therefore provides a more targeted feeling of warmth, particularly around a table or outdoor lounge area.
This is one of the reasons why infrared patio heaters are particularly well suited to outdoor spaces.
Hanging or freestanding patio heater: which should you choose?
The choice mainly depends on the configuration of your terrace.
Freestanding patio heaters
A freestanding model has the advantage of being movable according to your needs. It can be positioned close to an outdoor lounge area, a table or a relaxation area.
It is a good solution when the space does not offer a suitable suspension point.
Hanging patio heaters
When the terrace has a suitable structure, a hanging model offers several interesting advantages.
In particular, it allows you to:
- keep the floor completely clear;
- distribute heat from a central position;
- avoid adding a bulky appliance around the table;
- create a discreet installation that blends into the outdoor space.
Under a pergola, gazebo or covered terrace with a compatible structure, this type of solution can therefore be particularly practical.
Is a hanging patio heater a good choice above a table?
Yes, provided that the manufacturer's installation instructions and the required safety distances for the specific model are respected.
Positioning the heater above a table makes it possible to direct warmth towards the area that is actually being used without taking up any floor space.
This configuration is particularly suitable for:
- an outdoor table;
- a dining area beneath a covered structure;
- an outdoor lounge area;
- a terrace with a suitable pergola.
To create a truly comfortable outdoor space during the cooler season, a patio heater can also perfectly complement a pergola, which provides both shelter and structure to the terrace.
What power should you choose for a patio heater?
The required power depends on several factors: the area you want to heat, exposure to wind, installation height and the level of comfort you are looking for.
Outdoors, the aim is generally not to heat a large area evenly as you would an indoor room. It is more efficient to create a targeted comfort zone.
For a table or reasonably sized relaxation area, a power output of around 1500 W can provide an excellent balance between efficiency and energy consumption.
It can provide noticeable warmth within a defined area without necessarily requiring a much more powerful appliance.
An interesting option: the 1500 W hanging infrared patio heater
For users looking for a discreet solution that can be easily integrated beneath a suitable structure, the 1500 W hanging infrared patio heater is a particularly interesting option.
Thanks to its chain suspension system, it can be installed above an outdoor living area whenever a suitable structure is available.
Its 1500 W power output creates a targeted zone of warmth, while its stated radiant coverage can reach approximately 14 m², depending on installation and operating conditions.
Its steel construction also provides an appliance designed for suitable outdoor use while maintaining a relatively discreet appearance.
This type of model is particularly interesting when you want to heat a specific area without cluttering the terrace with a freestanding appliance.
How much electricity does a 1500 W electric patio heater use?
A 1500 W appliance consumes a maximum of approximately 1.5 kWh when operated at full power for one hour.
The actual cost therefore depends directly on your electricity tariff and how long the appliance is used.
For occasional use, for example during a meal or an evening lasting a few hours, consumption is easy to estimate:
- 1 hour: approximately 1.5 kWh;
- 2 hours: approximately 3 kWh;
- 3 hours: approximately 4.5 kWh.
The advantage of infrared heating is precisely that it targets the occupied area rather than trying to unnecessarily heat the entire outdoor space.
How can you improve comfort without unnecessarily increasing power?
The power of the patio heater is not the only factor that influences comfort.
The layout of the terrace also plays an important role.
Reduce exposure to wind
A terrace that is highly exposed to wind will always feel cooler. Whenever possible, positioning the dining area close to a wall, side protection or in a naturally more sheltered area can noticeably improve comfort.
Create a more sheltered area
A pergola or another suitable outdoor structure can help create a more comfortable and clearly defined space.
Position the patio heater correctly
A well-positioned appliance will often be more effective than a more powerful model installed too far away from the area that is actually being used.
With a hanging model, the aim is to position the radiant heat above or very close to the area where people are seated.
Can you use a patio heater under a pergola?
Yes, provided that the model is compatible with this type of use and that the safety distances specified by the manufacturer are strictly observed.
In particular, you should take into account:
- the material of the structure;
- the available height;
- the distance between the appliance and surrounding elements;
- the presence of fabrics or other potentially flammable materials;
- the recommendations provided in the product instructions.
A carefully planned installation can create a particularly comfortable space during September and autumn evenings.
Can a patio heater really extend the outdoor season?
Yes, and this is probably its main advantage.
Without heating, the terrace season depends directly on the outdoor temperature. As soon as evenings become cooler, people tend to use outdoor lounges and dining areas less frequently.
With a targeted source of warmth, it becomes possible to continue enjoying your outdoor space for longer.
A patio heater obviously does not turn an open terrace into a heated indoor room, but it can make a real difference on evenings when temperatures are simply a little too cool.
A few extra degrees of comfort can be enough to extend an evening by several hours.
Why is a patio heater particularly useful between the end of summer and autumn?
This period combines several particularly favourable conditions:
- the days are often still bright;
- eating outdoors remains enjoyable;
- temperatures mainly drop in the evening;
- the terrace remains fully usable with a little additional warmth.
Rather than immediately putting away your outdoor furniture when summer ends, installing a heating solution can therefore allow you to continue enjoying your outdoor space for several additional weeks.
A comfortable terrace during the cooler season: consider the entire outdoor layout
A patio heater provides warmth, but outdoor comfort depends on the overall layout of the space.
A pleasant terrace in September or October can combine:
- a well-organised dining or relaxation area;
- a protective structure such as a pergola;
- suitable outdoor lighting;
- comfortable furniture;
- a patio heater positioned close to the area being used.
This combination can transform a terrace used mainly during summer into a genuine outdoor living area that can be enjoyed for much longer throughout the year.
At Chestergarden, specialist in tools, gardening, DIY and outdoor living, we offer a range of solutions designed to improve the comfort and usability of outdoor spaces throughout the seasons.
So, should you install a patio heater at the end of summer?
If you enjoy spending evenings on your terrace, the answer is clearly yes: there is no need to wait for the first genuinely cold days.
The end of summer is actually one of the times when this type of equipment makes the most sense. The days remain pleasant while evenings become cooler, precisely when a few extra degrees of comfort can help you continue making the most of your outdoor space.
A hanging infrared model can be particularly interesting beneath a suitable structure, while a freestanding model offers greater flexibility when there is no suitable suspension point.
