Flexel EcoSun C+ Far Infrared Calling Panels

As energy costs continue to rise, many organisations are looking for heating systems that improve comfort while reducing running costs. Far infrared ceiling heating is becoming an increasingly popular solution for commercial, public sector and residential buildings. The Flexel EcoSun C+ range combines advanced far infrared technology with UK manufacturing expertise. Designed and manufactured in Scotland, these ceiling heating panels provide efficient radiant warmth, simple installation and low maintenance.

This guide explains how Flexel EcoSun C+ works, where it performs best and why it is an effective alternative to traditional heating systems.

What Is Flexel EcoSun C+?

The Flexel EcoSun C+ is a far infrared ceiling heating panel designed for suspended ceiling grids and surface-mounted ceiling installations. Unlike conventional heating systems that warm the air first, far infrared heating transfers heat directly to people, floors, walls and furniture. This creates a comfortable indoor environment while reducing wasted energy.

EcoSun C+ is suitable for a wide range of buildings, including:

  • Offices
  • Schools and universities
  • Healthcare facilities
  • Churches and community halls
  • Retail premises
  • Hospitality venues
  • Residential properties
  • Modular buildings
  • Public sector buildings

How Far Infrared Heating Works

Far infrared heating works in a similar way to the sun. It emits radiant energy that travels through the air and warms objects and occupants directly. Traditional convection systems rely on warming the air. As warm air rises, heat can accumulate at ceiling level where it provides little benefit to occupants. Far infrared heating reduces this problem by directing heat where it is needed most.

Benefits of far infrared heating include:

  • Faster perceived warmth
  • Reduced heat stratification
  • Lower ceiling heat losses
  • Improved comfort levels
  • Less air movement
  • Reduced dust circulation
  • Better performance in intermittently occupied spaces

As a result, many buildings feel comfortable at lower thermostat settings compared with conventional heating systems.

Why Choose Ceiling Heating?

Ceiling-mounted heating offers several practical advantages.

Maximises Usable Space

Because the heating panels are mounted overhead, walls remain free for furniture, displays, shelving and equipment.

Ideal for Modern Buildings

EcoSun C+ integrates neatly into suspended ceiling systems, creating a clean and professional appearance.

Low Maintenance

Unlike traditional wet heating systems, EcoSun C+ requires no:

  • Boilers
  • Pumps
  • Pipework
  • Annual combustion servicing

This helps reduce maintenance costs throughout the life of the building.

Excellent Zonal Control

Individual rooms and zones can be controlled independently. This allows heating to be used only where and when it is required.

Key Features of Flexel EcoSun C+

Made in Scotland Since 1978

Flexel has manufactured electric heating technologies in Glenrothes, Scotland since 1978. The company is recognised as the UK’s longest-running far infrared element manufacturer.

Advanced Ink-Based Heating Technology

EcoSun C+ uses Flexel’s unique printed conductive ink technology rather than conventional wire-based elements.

This provides:

  • Even heat distribution
  • Consistent radiant output
  • Lightweight construction
  • Efficient heat transfer
  • Long-term reliability
Comfortable Radiant Heat

The system provides gentle, natural warmth without the dry air sensation often associated with forced-air heating systems.

Silent Operation

EcoSun C+ contains no fans or moving parts, making it completely silent during operation.

Easy Installation

The panels are suitable for:

  • Suspended ceiling grids
  • Surface-mounted ceilings
  • Refurbishment projects
  • New-build developments
Smart Heating Controls

EcoSun C+ is compatible with Flexel’s range of thermostats and smart controls, including Wi-Fi-enabled options for remote management and scheduling.

Where EcoSun C+ Performs Best

Offices

Far infrared heating provides excellent comfort while maximising wall space and enabling room-by-room control.

Schools and Universities

Silent operation and low maintenance make EcoSun C+ ideal for educational environments.

Healthcare Buildings

Radiant heating can help improve occupant comfort while reducing air circulation compared with traditional convection systems.

Churches and Historic Buildings

Large-volume buildings can be difficult and expensive to heat. Far infrared heating focuses warmth on occupants rather than heating unused air space.

Modular Buildings

Simple installation and minimal infrastructure requirements make EcoSun C+ an excellent solution for modular construction projects.

Residential Properties

EcoSun C+ is suitable for apartments, extensions, home offices, garden rooms and low-energy homes.

Energy Efficiency Benefits

Heating is often the largest energy demand within a building. Choosing an efficient heating system can significantly reduce operating costs.

EcoSun C+ offers several energy-saving advantages:

  • Reduced heat wastage
  • Faster warm-up times
  • Lower thermostat settings
  • Precise zonal control
  • No pipework distribution losses
  • Reduced maintenance requirements

When combined with renewable electricity sources such as solar PV, EcoSun C+ can form part of a highly sustainable heating strategy.

Supporting Net Zero Goals

Many organisations are replacing fossil fuel heating systems as part of their decarbonisation plans.

EcoSun C+ supports this transition through:

  • Fully electric operation
  • Compatibility with renewable energy
  • Reduced infrastructure requirements
  • Efficient zonal heating
  • Lower ongoing maintenance demands

This makes the system particularly attractive for:

  • Public sector buildings
  • Schools and colleges
  • Church decarbonisation projects
  • Commercial retrofit programmes

Heating Control Options

Effective controls are essential for maximising efficiency.

Flexel offers a range of control solutions, including:

  • Programmable thermostats
  • Smart Wi-Fi thermostats
  • App-based control systems
  • Zoned heating management
  • Timed heating schedules

These controls help ensure energy is only used when required.
