The ECOSUN U+ Infrared Heating Panel is a high-performance, slimline radiant heater designed for both wall and ceiling mounting. Featuring a unique thermocrystal textured surface, it delivers enhanced infrared output, making it an efficient and versatile heating solution for residential, commercial, and industrial environments.
Unlike traditional heating systems, the ECOSUN U+ uses infrared technology to warm people, surfaces, and objects directly, creating a more comfortable environment without relying on air circulation. This results in improved comfort at lower air temperatures and reduced energy waste.
Standard finish: RAL 9016 Traffic White. Custom finishes may be available on request.
Key Features
- Thermocrystal surface technology – textured quartz-based coating increases surface area by up to 2.5x for improved heat emission
- Infrared radiant heating – delivers direct, comfortable warmth without heating the air
- Wall or ceiling mounting – flexible installation for any environment
- Suspended ceiling compatible – ideal for office grid systems (600x600 layouts)
- Slimline, space-saving design – frees up wall and floor space
- Silent operation – no fans, no moving parts
- Maintenance-free – no servicing required
- Durable galvanised steel construction with high-emissivity coating
- Localised heating capability – heat only the areas you use
Panel Sizes & Applications
- 300W panel – replaces one 600mm x 600mm ceiling tile
- 600W panel – replaces two ceiling tiles for higher output
This makes the ECOSUN U+ particularly effective in offices, commercial buildings, and suspended ceiling systems, where discreet, zoned heating is required.
Where This Heater Works Best
- Offices & commercial spaces – ideal for suspended ceilings and zoned heating
- Studios & workshops – targeted heat without heating unused areas
- Homes & apartments – discreet wall or ceiling-mounted heating
- Retail & public buildings – efficient, low-maintenance heating solution
Heating Performance & Efficiency
The thermocrystal surface significantly improves infrared output by increasing the active heat-emitting area. This results in:
- Faster perceived warmth
- Improved comfort at lower thermostat settings
- Reduced heat loss compared to convection heating
- Better performance in ventilated or open spaces

Installation & Control
The ECOSUN U+ can be installed as part of a complete heating system or used for spot heating specific zones. It works best when paired with modern controls such as:
- Smart Thermostats for scheduling and zoning
- Programmable timers for energy-efficient operation
- Multi-zone control setups for larger spaces

FAQ's
What makes the ECOSUN U+ different from standard infrared panels?
The U+ features a thermocrystal textured surface that increases the heat-emitting area, improving efficiency and delivering stronger radiant output compared to smooth panels.
Can the ECOSUN U+ be installed in suspended ceilings?
Yes. The panel is designed to fit standard ceiling grid systems, making it ideal for offices and commercial buildings.
Is this heater suitable for full room heating?
Yes. When correctly sized and controlled, it can be used as a primary heating system or as part of a zoned setup.
Does infrared heating work well in ventilated spaces?
Yes. Because it heats surfaces rather than air, infrared heating is less affected by air movement or ventilation compared to convection systems.
Does the panel require maintenance?
No. The ECOSUN U+ has no moving parts, requires no servicing, and operates silently.
Can I control it with a smart thermostat?
Yes. The panel works with a range of programmable and smart thermostats for improved comfort and energy efficiency.
What colour is the panel?
The standard finish is RAL 9016 Traffic White, with bespoke colour options potentially available on request.
Is it suitable for offices and commercial environments?
Yes. It is widely used in offices, retail spaces, and public buildings due to its discreet design and efficient zoned heating capability.
