Many people believe that infrared heating is a single technology. In reality, there are several different types of infrared heating that work in different ways and are developed for different environments.
That's why a classic heat lamp on an outdoor terrace feels completely different from an infrared panel in the living room or a Dark Heater in a conservatory. Although all three use infrared heat, the wavelength, temperature, comfort and area of application differ.
To choose the right heating solution, it is important to understand the difference between long-wave, medium-wave and short-wave infrared heat.
It's about wavelength
All infrared heat is based on infrared waves. The difference lies in the wavelength and temperature of the heat source.
In general, shorter wavelengths require higher temperatures to generate heat, while longer wavelengths can be produced at significantly lower temperatures. This is why different types of infrared heat are experienced so differently.
Short-wave infrared heat provides an intense and immediate feeling of warmth, while long-wave infrared heat is experienced as significantly softer and more natural.
Overview of the three types of infrared heating
| Type | Name | Temperature | Typical product | Common area of use |
|---|---|---|---|---|
| IR-C | Long-wave | approx. 60–100°C | Infra panels | Home, office, hotel, yoga studios |
| IR-B | Medium wave | approx. 150–250°C | Dark Heater | Conservatories, restaurants, terraces |
| IR-A | Shortwave | approx. 500–600°C | Heat lamps | Outdoors, windy environments |
All technologies have their strengths. Which one is best depends entirely on where the heat is to be used.
Therefore, the same infrared heat can feel completely different.
Two products can both be described as infrared heating but still provide a completely different experience.
The difference is mainly about the temperature of the heat source. The higher the temperature, the more intense the heat is experienced. That is why a heat lamp feels so different compared to an infrared panel in a living room.
Same technology – different experience
| Heat source | Typical temperature | Perceived feeling |
|---|---|---|
| Infrared panel | 60–100°C | Soft and even heat |
| Dark Heater | 150–250°C | More intense heat without bright light |
| Heat lamp | 500–600°C | Immediate and intense heat |
Many describe long-wave infrared heat as the most natural heat because it is reminiscent of the feeling when the sun peeks out after a cold or cloudy day.
Long-wave infrared heat (IR-C) – best for permanent heating
Long-wave infrared heat, also known as IR-C, is the technology used in modern infrared panels. The panels operate at relatively low temperatures and emit a soft and comfortable heat without visible light.
Because the heat is distributed evenly and naturally, long-wave infrared heating is particularly suitable for permanent heating in environments where people stay for longer periods.
Benefits of long-wave infrared heating
Comfortable and even heat
No disturbing light
Warmer floors and surfaces
High comfort
Quiet operation
Perfect for permanent heating
Long-wave infrared heat is often used in:
Villas
Apartments
Office
Hotel
Yoga studios
Public environments
That is also why Infracenter's infrared panels use long-wave IR-C technology.
Mid-wave infrared heat (IR-B) – when you need more power
Medium-wave infrared heat acts as a bridge between traditional infrared panels and classic heat lamps.
It operates at higher temperatures than an infrared panel but significantly lower temperatures than a short-wave heat lamp. The result is higher heat output without the harsh red or orange light that many people associate with older patio heaters.
When is a Dark Heater best suited?
Dark Heater is particularly popular in environments where you want more effect than a traditional infrared panel can deliver but at the same time want to avoid bright light.
Common uses are:
Conservatory
Terraces
Restaurants
Cafes
Pergolas
Semi-open environments
Dark Heater uses mid-wave IR-B technology and combines high heat output with a significantly more comfortable feeling of warmth than traditional heat lamps.
Shortwave infrared heat (IR-A) – built for open environments
Short-wave infrared heat works at very high temperatures, often between 500 and 600 degrees. It is the technology used in many classic heat lamps and patio heaters.
The big advantage is that the heat is felt almost immediately and is very little affected by wind and air circulation.
When is short-wave infrared heating best suited?
Short-wave infrared heat is particularly suitable for:
Outdoor dining
Port environments
Industrial areas
Completely open terraces
Places with a lot of wind
The disadvantage is that the heat is often experienced more intense and that the products usually emit a distinct red or orange glow.
What type of infrared heating should you choose?
The choice primarily depends on where the heat will be used.
Choose infrared panels if you want
Heating a home
Create high comfort
Get even temperature
Heating offices or hotels
Avoid visible light
Have permanent heating
Choose Dark Heater if you want
Heating conservatory
Heating terraces
Warm restaurants
Get higher power
Avoid red heat lamps
Extend the outdoor season
Choose short-wave infrared heat if
It is very windy.
The heat must be felt immediately
The environment is completely outdoors
Bright light is not a problem
The right type of infrared heating for the right environment
A common misconception is that the same product fits everywhere. In reality, different environments have completely different requirements for heat.
A living room requires high comfort and an even temperature. A conservatory requires more power. An outdoor terrace in the wind requires a completely different type of heat source.
Since 2014, Infracenter has specialized in infrared heating and developed its own products for both permanent heating and more demanding environments. Today, the company is the largest specialist in infrared heating panels in the Nordic region, offering solutions for homes, businesses, conservatories, restaurants and commercial properties.

FAQ – Frequently asked questions about long-wave and short-wave infrared heating
What is the difference between long-wave and short-wave infrared heat?
Long-wave infrared heat works at lower temperatures and provides a softer feeling of warmth. Short-wave infrared heat works at significantly higher temperatures and provides a more intense heat.
What do IR-A, IR-B and IR-C mean?
IR-A is short-wave infrared heat, IR-B is medium-wave infrared heat and IR-C is long-wave infrared heat.
Which infrared heater is best for a home?
For homes, long-wave infrared heating in the form of infrared panels is normally the best choice because it provides high comfort and even heat distribution.
What is a Dark Heater?
A Dark Heater uses mid-wave infrared heat and provides high heat output without the strong red light from traditional heat lamps.
Is the Dark Heater better than a heat lamp?
It depends on the area of use. In conservatories, restaurants and terraces, many people prefer Dark Heaters because the heat is perceived as more pleasant and the light is significantly more discreet.
Summary
Long-wave, medium-wave and short-wave infrared heating are based on the same basic principle but are developed for different environments and needs. Infrared panels provide high comfort and are suitable for permanent heating, Dark Heater is suitable for conservatories and terraces, while short-wave heat lamps are best in open and windy environments.
When the right technology is used in the right place, the result is both better comfort and more efficient heating. That's why it's important to understand the difference between IR-A, IR-B and IR-C before choosing a heating solution.
