Why Fitness Clubs Choose HOT STUDIO
The quality of a heated fitness studio is defined not only by its temperature, but also by how the heat is experienced.
Traditional heating systems primarily warm the air, while HOT STUDIO uses infrared radiant heating to warm people, the floor, and surrounding surfaces directly.
The result is a more even heat distribution, greater comfort, and a more enjoyable environment for both clients and instructors.
HOT STUDIO is more than just another group fitness studio.

Frequently Asked Questions
1. How quickly does a HOT STUDIO reach operating temperature?
In a properly designed HOT STUDIO equipped with a Sundirect infrared heating system and ceiling heights of up to 3 metres, the room typically reaches 38°C in:
approximately 50 minutes from 16–17°C
approximately 40 minutes from 20°C
Sundirect IC Series panels reach their operating temperature in approximately 7 minutes. However, the overall warm-up time also depends on the heating of the floor, walls, and other room surfaces.
The required heating capacity for each HOT STUDIO project is calculated individually, taking into account the room size, ceiling height, insulation, ventilation, and the desired warm-up time.
2. Do Sundirect infrared panels require regular maintenance?
No. Sundirect infrared panels contain no moving parts, fans, or filters. Under normal operating conditions, only occasional cleaning of the panel surface is required to remove dust.
3. What happens if the thermostat receiver fails?
There is no need to replace the entire panel. If the thermostat receiver fails, we supply a replacement unit that can be installed by a qualified electrician in approximately 15–20 minutes.
4. What is the service life of Sundirect infrared panels?
Sundirect infrared panels are manufactured using high-quality German technology and are designed for long-term commercial operation. Their expected service life is approximately 100,000 operating hours, providing reliable performance for professional HOT STUDIO applications.
5. Has the HOT STUDIO system been proven in real commercial projects?
Yes. Sundirect infrared heating systems are used daily in MyFitness HOT STUDIO facilities in Latvia, maintaining stable temperatures for intensive group training sessions.
These real-world commercial installations demonstrate that the system is suitable for professional use, providing reliable operation and consistent temperature control in everyday operation.
6. Can a HOT STUDIO be divided into multiple temperature zones?
Yes. Using Smart 2.0 Pro thermostats, a studio can be divided into multiple independently controlled temperature zones.
Each thermostat can control up to 10 Sundirect infrared panels, providing flexible and efficient temperature management throughout different areas of the studio.
7. What happens if one of the infrared panels stops working?
A Sundirect HOT STUDIO heating system consists of multiple independent infrared panels. If one panel stops operating, the rest of the system continues to function normally, and the studio remains heated.
The faulty panel can be replaced without dismantling the entire heating system, minimizing downtime and allowing the system to be restored quickly.
8. How much does a HOT STUDIO heating system cost?
The cost of a HOT STUDIO heating system is calculated individually for each project.
It depends on the room size, ceiling height, insulation, ventilation design, and the required heating capacity.
After evaluating the technical specifications of the space, we prepare a customized technical solution, an infrared panel layout plan, and a detailed quotation.
9. At what height should the thermostat be installed in a HOT STUDIO?
The recommended installation height is 1.4–1.6 metres above the floor. This allows the thermostat to measure the temperature within the occupied zone, providing more accurate temperature control during classes.
For optimal performance, the thermostat should be installed on an internal wall, away from direct infrared radiation, windows, doors, and ventilation airflow. Correct thermostat placement helps maintain a stable and consistent temperature throughout every class.
