Infrared Heating vs. Hot Air Heating – Which Is the Better Solution for a HOT STUDIO?

Target audience: Fitness studio owners, investors, fitness club managers, architects, designers, HVAC specialists, group fitness instructors, fitness club members, and participants in yoga, Pilates and other group exercise classes who want to understand how HOT STUDIO workouts differ from traditional classes and the benefits of a warm, comfortable training environment heated by infrared technology.

When designing a professional HOT STUDIO that needs to maintain temperatures between 28°C and 38°C, choosing the right heating system is one of the most important decisions.

Today, two main heating approaches are commonly used in HOT STUDIO projects:

• Traditional hot-air (convection) heating.

• Modern infrared (IR) heating.

Both technologies can heat a room to the required temperature.

However, their operating principles, energy efficiency and impact on participant comfort differ significantly.

Heating Principles and Heat Distribution

Hot Air Heating

Hot-air heating systems first heat the air in the room and then distribute it throughout the studio using fans.

Due to the laws of physics, warm air naturally rises.

As a result:

• Temperatures near the ceiling can become significantly higher.

• Temperatures at floor level, where participants exercise, may be lower.

• Fans create continuous air movement.

• In larger spaces, this can result in uneven heat distribution.

Infrared Heating

Infrared heating panels operate on a different principle.

Unlike hot-air heating, infrared panels transfer most of their thermal energy directly to people and surrounding surfaces.

They heat:

• The human body.

• The floor.

• The walls.

• Other surfaces in the room.

The air gradually warms as it comes into contact with these heated surfaces.

This creates a more even thermal environment without noticeable forced air currents.

Air Quality and Participant Comfort

Exercising at 38°C already places considerable physical demands on the body.

That is why air quality becomes just as important as temperature itself.

Hot Air Heating

Fans continuously move large volumes of air.

This can:

• Create noticeable air currents.

• Increase the circulation of dust and other airborne particles.

• Reduce relative humidity and increase moisture evaporation from the skin.

For some participants, these conditions may cause additional discomfort during intense physical activity.

Infrared Heating

Because infrared heating panels operate without fans:

• There is no forced air movement from the heating panels.

• The indoor environment feels more natural.

• Participants can focus more easily on their workout.

This is particularly important for yoga, Pilates and other activities where breathing plays an essential role in the training experience.

Energy Efficiency

One of the most important considerations for any fitness club is operating costs.

Hot Air Heating

When doors are opened or ventilation systems are operating, some of the heated air is removed from the room.

The heating system must then heat the replacement air.

The more intensive the ventilation, the greater the heat losses.

Infrared Heating

Infrared panels heat not only people but also the surrounding building structures.

Floors, walls and other surfaces act as thermal mass, storing heat.

Even while ventilation is operating, these surfaces continue to radiate heat.

This helps maintain a more consistent feeling of warmth during ventilation and allows the heating system's control features to be used efficiently.

Hygiene and Studio Maintenance

HOT STUDIO environments typically experience significantly higher moisture levels than conventional fitness studios.

If wall surfaces remain cool for extended periods, condensation may form.

Over time, condensation increases the risk of mould growth.

Infrared heating also warms wall surfaces, helping to reduce the likelihood of condensation and maintain a more stable indoor environment.

Studio Design and Aesthetics – Another Advantage of Infrared Heating

A modern HOT STUDIO is more than just a heated exercise room. It is a carefully designed environment where interior design, lighting, acoustics and comfort combine to shape the participant experience.

One of the key advantages of infrared heating is the ability to install heating panels on the ceiling, integrating them into the overall studio design.

This approach offers several benefits:

• Unobstructed walls and floor space. Heating equipment does not occupy valuable space that can be used for mirrors, lighting or interior design elements.

• Clean, uncluttered interior design. Slim infrared panels can blend harmoniously into a modern fitness studio.

• Carefully planned panel positioning. Infrared panels are installed on the ceiling, taking into account room dimensions, ceiling height and the required heating capacity to ensure even heat distribution throughout the HOT STUDIO.

• Fewer visible technical elements. Additional heating air-distribution grilles or ducts are not required unless needed by the ventilation system.

Ceiling installation makes it possible to combine effective heating with an attractive and functional HOT STUDIO interior.

Practical Examples

This approach is already being used in the Baltic States.

SUNDIRECT has completed three professional MyFitness HOT STUDIO infrared heating projects in the Baltics:

• MyFitness Galerija Centrs — Riga, Latvia.

• MyFitness Galleria Riga — Riga, Latvia.

• MyFitness Tartu Kaubamaja — Tartu, Estonia (opened in October 2026).

Expansion continues in Tallinn.

• Another HOT STUDIO is scheduled to open at MyFitness Rocca al Mare in Tallinn in November 2026, featuring SUNDIRECT infrared heating.

Infrared heating was selected for these MyFitness HOT STUDIO projects to provide:

Stable temperatures throughout each class.

Even heat distribution.

A comfortable indoor environment.

Quiet operation without heating fans.

These projects demonstrate that a professional HOT STUDIO is not simply about achieving higher temperatures, but about choosing the right heating technology.

Conclusion

Both heating technologies can achieve the required temperatures in a HOT STUDIO.

However, in a professional fitness environment, what matters is not only the temperature reached but also how participants experience the environment throughout the entire class.

Infrared heating offers several important advantages:

• More even heat distribution.

• Minimal air movement.

• Quieter operation.

• A more comfortable indoor environment.

• More efficient use of energy.

• Reduced risk of condensation.

• Seamless integration into studio design through ceiling-mounted panels.

Infrared heating is becoming an attractive solution for professional HOT STUDIO environments where comfort, quiet operation and thoughtful design are priorities.
