This makes it especially suitable for restaurants, churches and reception areas where atmosphere matters.
Efficient, Directional Infrared Heating
Unlike conventional heating systems, the ECOSUN TH directs heat exactly where it is needed.
- Radiant heat targeted onto seating and occupied areas
- Reduces wasted heat compared to convection systems
- Effective in larger or partially open spaces
- Improved comfort with lower energy waste
Learn more about this in our Infrared Heating Guide.
Flexible Installation Options
The ECOSUN TH can be installed to suit the layout and heating needs of the space.
- Wall-mounted for targeted heating zones
- Ceiling-mounted for wider coverage
- Tiltable brackets for directional heat control
- Simple 230V electrical installation
This flexibility allows for effective heating design in both new and retrofit projects.
Available Outputs for Different Spaces
The ECOSUN TH is available in multiple power outputs, allowing it to be tailored to different room sizes and heating requirements:
- 1000W – smaller rooms and targeted heating
- 1500W – medium-sized spaces
- 2000W – larger rooms and open areas
- 3000W – high-output heating for large commercial spaces

FAQ's
Is the ECOSUN TH suitable for commercial spaces?
Yes. It is specifically designed for commercial environments such as offices, hospitality venues, churches and public buildings.
What does zero-light heating mean?
Zero-light heaters do not produce visible glow, making them ideal for environments where appearance and comfort are important.
Is this heater suitable for restaurants and cafés?
Yes. It is widely used in hospitality settings because it provides comfortable heat without affecting lighting or atmosphere.
Can the ECOSUN TH heat large spaces?
Yes. With outputs up to 3000W and directional heat, it is suitable for large rooms and open-plan environments.
Is ceiling mounting better than wall mounting?
Ceiling mounting often provides wider heat coverage, while wall mounting is useful for targeting specific areas.
Does it work in semi-outdoor or enclosed terrace areas?
Yes. Infrared heating is effective in these environments because it heats people directly rather than the surrounding air.
