Heat Pump Water Heater

Heat Pump Calorifiers: What They Are and How They Work

Heat pumps generate water at lower temperatures—typically 50-55°C—compared to traditional boilers. A heat pump calorifier is a specialized storage unit designed to convert this low-temperature energy into domestic hot water with maximum efficiency.

Core Purpose

• High Efficiency at Low Temperatures: Rapidly transferring heat to water via large-surface-area coils to minimize waiting times.

• Comfort and Continuity: Ensuring an uninterrupted supply of hot water even when the heat pump enters "defrost" mode.

Key Features of FENNEX Heat Pump Calorifiers

Our engineering sets us apart in the market through several distinct advantages:

• Expanded Heat Transfer Surface: FENNEX calorifiers feature coil surface areas significantly larger than standard units to account for low-temperature operation.

• Rapid Thermal Response: This expanded surface allows water to reach the desired temperature much faster.

• Lowest Dished End Design: The coil technology extends to the absolute bottom of the tank.

• 100% Homogeneous Heating: This ensures no cold zones remain at the base, allowing the entire tank capacity to be heated uniformly.

• One-Piece Removable Coil via Flange Cover: Our signature feature allows the flexible coil to be removed and reinstalled as a single component through the flange cover.

• Lower Maintenance Costs: This innovation simplifies repairs and significantly extends the product's lifespan.

• Hygiene and Health: Homogeneous heating physically prevents the formation of cold spots where bacteria, specifically Legionella, could proliferate.

• High-Density Insulation: Using 44kg/m³ high-density insulation, the energy produced is preserved for long periods, minimizing thermal loss.

FEN-X Plus Defender: A Flexible and Strong Armor

The internal surfaces of our heat pump calorifiers are protected by FEN-X Plus Defender, a technology that surpasses traditional and brittle enamel coatings. This is a hybrid protection system designed to extend the vessel's life.

Why FEN-X Plus Defender?

• Thermal Flexibility: Unlike traditional coatings that may crack during expansion and contraction, this flexible structure expands along with the metal body.

• Structural Integrity: It does not crack, flake, or peel over time.

• Maximum Corrosion Resistance: This coating completely eliminates contact between water and the metal surface, effectively ending the risk of rust.

• Smooth Surface and Scale Prevention: The technology creates a glass-like smooth texture that prevents lime and sediment from adhering to the surface.

• Full Hygiene Standards: Its non-porous structure does not harbor bacteria, maintaining the purity and hygiene of your water at drinking-quality levels.
