Single Coil Boiler

Single Coil Calorifiers: Maximum Energy Efficiency from a Single Source

The FENNEX Single Coil Calorifier series combines high-performance heat transfer with durability to meet the hot water needs of modern buildings in the most economical way. It is designed to transfer energy from a single heat source—such as a boiler, combi boiler, heat pump, or solar energy—to domestic water with minimum loss.

Differentiating Details with FENNEX Engineering

Unlike ordinary calorifiers, FENNEX provides technology focused on longevity and hygiene:

• Lowest Dished End Design: FENNEX’s exclusive technology places the coil at the very bottom of the tank, ensuring water heats up from the lowest point.

• Energy Optimization: This design eliminates "dead zones" within the tank, allowing for full energy efficiency.

• One-Piece Removable Coil: Maintenance is simplified as the coil can be removed as a complete component and easily replaced in case of calcification or failure.

• Cost Efficiency: This feature extends the system's lifespan while keeping maintenance costs to a minimum.

• Maximum Hygiene and Safety: Homogeneous heating starting from the bottom prevents water from remaining stagnant and stops cold spots from forming.

• Legionella Protection: This process minimizes the risk of bacteria (Legionella) formation, providing the healthiest water for your family or business.

Key Technical Advantages

Application Areas

This is the ideal solution for any area requiring efficient and uninterrupted hot water via a single heat source, including:

• Detached houses and villas

• Office buildings

• Small-scale businesses
