A greenhouse is about so much more than cultivation. For many, it is a place for relaxation, socializing and recovery. At the same time, you want to give the plants the best possible conditions to thrive for as much of the year as possible.
The challenge is that many greenhouses quickly become cold when the temperature drops outside. Large glass surfaces let in an incredible amount of light, but also cause heat to dissipate faster than in regular rooms.
Therefore, the choice of heating system becomes extra important.

Plants want light – not large heating systems
In a greenhouse, light is often the most important resource. That's why many people take great care in choosing the right glass, the right location and the right plants.
At the same time, many people forget that the heating system also affects how much light reaches the plants.
Large elements along the glass sections take up space. Freestanding heaters steal growing space. Even certain types of heating systems can limit light if placed incorrectly.
Therefore, many greenhouse owners choose heating solutions that take up minimal space while providing high comfort.
Warm air in the ceiling doesn't help plants
Many people are surprised by how much heat is actually lost through the roof when using traditional heaters in a greenhouse. The warmest air collects at the top of the building, while plants, pots and people are located several meters below.
Infrared heat works differently. Instead of heating the air, it heats plants, growing surfaces, floors and people directly. This means that the heat ends up where it is most useful and not in the ceiling.
The result is often a more comfortable climate where both people and plants can thrive better during the colder months of the year.
Why Dark Heater works so well in greenhouses
One of the big advantages of the Dark Heater is that it can be mounted high up where it neither disturbs the cultivation nor limits the light.
At the same time, it provides pleasant infrared heat that warms people, plants, pots and other surfaces directly.
For many greenhouse owners, this means they can extend the season without having to compromise on what the plants need most – sunlight.
In addition, the Dark Heater does not emit a strong orange or red glow like many traditional patio heaters. The greenhouse retains its natural appearance even when the heater is in use.

Not all infrared heaters are suitable for greenhouses
Many people are not aware that there are different types of infrared heat.
| Technique | Type of heat | Suitable for greenhouses |
|---|---|---|
| IR-A | Short-wave infrared heat | Less suitable near sensitive plants |
| IR-B | Medium-wave infrared heat | Very good |
| IR-C | Long-wave infrared heat | Excellent |
Shortwave heaters are designed to provide very intense heat and are often used in open patios where wind and cold quickly cool down the surroundings.
In greenhouses, orangeries and other environments where plants are kept for longer periods, medium-wave or long-wave infrared heat is often a better choice.
Greenhouses are used today for much more than cultivation.
Modern greenhouses are used today as much more than just a place for tomatoes and cucumbers.
Many function as:
Orangeries
Lounges
Dining areas
Winter gardens
Workplaces
Places to socialize
Therefore, it is not enough for plants to thrive. People must do so too.
A comfortable temperature means that the greenhouse can be used for significantly more months of the year and becomes a natural part of the home instead of a room that is empty for much of the year.
Infrared panels are often better suited for conservatories and glazed balconies.
In a classic greenhouse, the Dark Heater is often the most practical choice because it takes up minimal space and does not affect the light penetration.
In orangeries, conservatories and glazed balconies, the conditions are often different.
Here, long-wave infrared panels are often a very good alternative. They heat floors, walls, furniture, pots and other surfaces in a soft and pleasant way, while spreading the heat evenly throughout the environment.

The result is a comfortable environment where both people and plants have better conditions to thrive during the colder months of the year.
How much heat is needed in a greenhouse?
There is no exact rule because the need is affected by glass surfaces, insulation, ceiling height and the temperature you want to achieve.
To extend the season, around 200W per m² is usually a good starting point.
| Surface | Recommended power |
|---|---|
| 5 m² | About 1000W |
| 10 m² | About 2000W |
| 15 m² | About 3000W |
| 20 m² | About 4000W |
The goal is rarely to create summer temperatures in the middle of winter. However, the right heating system can make a big difference during spring, autumn and cooler summer evenings.
That's why many greenhouse owners choose Infracenter
Since 2014, Infracenter has helped customers create comfortable environments with infrared heating.
Dark Heater has become a popular choice in greenhouses, orangeries and conservatories where you want to combine high comfort with maximum light.
At the same time, our infrared panels are used in everything from conservatories and glazed balconies to homes, offices and commercial properties.
Regardless of whether the goal is to extend the growing season or create a more comfortable environment for both people and plants, there are now significantly smarter alternatives than traditional heating systems.
FAQ
Can you use the Dark Heater in a greenhouse?
Yes. Dark Heater is very suitable for greenhouses because it takes up minimal space, does not block the light and provides pleasant infrared heat.
Is infrared heat good for plants?
Medium-wave and long-wave infrared heat works very well in environments where plants live. They help create a more even and comfortable climate.
How much power is needed in a greenhouse?
As a general guideline, around 200W per m² is usually a good starting point when the goal is to extend the season.
Should I choose Dark Heater or infrared panel?
In classic greenhouses, Dark Heater is often the most practical choice because it does not affect the light entering. In conservatories, orangeries and glazed balconies, infrared panels are often a very good alternative.
