Far Infrared ceiling heater
The Flexel EcoSun S+ is a powerful and efficient Far Infrared heating solution. It delivers comfortable radiant heat while helping to reduce energy consumption. The EcoSun S+ combines modern design, smart controls, and reliable performance. As a result, it is ideal for commercial, industrial, community and heritage buildings. Ideas for large spaces that are traditionally difficult to heat.
What Is the Flexel EcoSun S+?
The EcoSun S+ is a ceiling mounted Far Infrared heater designed for larger spaces. Unlike traditional heating systems, it does not heat the air first. Instead, it warms people, surfaces and objects directly. This approach creates a comfortable indoor environment while reducing energy waste. It also helps improve heating performance in buildings with high ceilings or large open areas.
The Flexel EcoSun S+ is suitable for:
- Churches and places of worship
- Village halls
- Sports halls
- Warehouses
- Workshops and garages
- Schools and colleges
- Agricultural buildings
- Retail premises
- Commercial spaces
How Does Far Infrared Heating Work?
Far Infrared heating works in a similar way to the sun. The EcoSun S+ emits radiant heat that travels through the air and warms solid objects directly. Because of this, occupants feel comfortable more quickly than with conventional heating systems.
Key benefits include:
- Faster warmth
- Reduced heat stratification
- Lower thermostat settings
- Less dust circulation
- Improved energy efficiency
As a result, many buildings can reduce their heating costs while maintaining comfort.
Why Choose the Flexel EcoSun S+?
High Heat Output
Flexels EcoSun S+ is designed for demanding heating applications. It is available in several sizes and wattage to suit different buildings and layouts. This flexibility makes it ideal for large commercial and industrial spaces.
Modern Design
The heater is available in both white and black finishes along side an anti corrosive version. Other colour options can me manufactured to order, therefore it can blend into most ceiling designs or complement modern architectural features. The slim profile also helps maintain a clean and professional appearance.
Energy-Efficient Heating
Heating often represents one of the largest energy costs in a building. However, the Flexel EcoSun S+ helps reduce wasted energy by heating people and surfaces directly. When paired with intelligent controls, users can achieve even greater savings.
Benefits include:
- Zoned heating
- Smart scheduling
- Remote control
- Reduced energy consumption
- Lower running costs
Why Is the Flexel EcoSun S+ Ideal for Churches?
Churches can be difficult and expensive to heat. Many have high ceilings, large internal volumes, and solid stone construction. Traditional heating systems often waste energy by heating large amounts of air. In contrast, the EcoSun S+ delivers warmth directly to occupied areas.
Benefits for churches include:
- Fast response times
- Lower operating costs
- Silent operation
- Minimal maintenance
- No boiler requirements
- Easy installation
- Suitable for heritage buildings
For this reason, many churches are choosing Far Infrared heating as part of their decarbonisation strategy.
Simple and Cost-Effective Installation
The Flexel EcoSun S+ is designed for straightforward installation by qualified electricians. Because the heaters are ceiling mounted, they remain out of the way while providing effective heat coverage. Unlike traditional heating systems, there is no need for:
- Pipework
- Pumps
- Boilers
- Gas connections
- Plant rooms
As a result, installation is faster and less disruptive.
Smart Heating Controls
Smart controls can help maximise comfort and efficiency. Flexel recommends using the Flexel Touch WiFi Thermostat together with the Fenix Control App. Users can:
- Adjust heating remotely
- Create schedules
- Control heating zones
- Reduce unnecessary energy use
- Optimise comfort levels
This is especially useful in churches, village halls, and community buildings with irregular occupancy patterns.
Low Maintenance and Long Lifespan
The Flexel EcoSun S+ contains no moving parts. It also requires no water circulation and no combustion process. As a result, maintenance requirements are minimal. Common issues associated with traditional heating systems can be avoided, including:
- Boiler breakdowns
- Water leaks
- Pump failures
- Air locks
- Annual gas servicing
This helps reduce long-term ownership costs.
