Calorifer Repair

In HVAC systems, calorifers typically work by passing air over coils filled with hot fluid. In marine and industrial settings, they may be integrated into boiler systems or operate as standalone heating units.

Common Applications

• HVAC systems – heating incoming ventilation air in large buildings
• Marine vessels – heating air in crew quarters or work areas using boiler-generated steam or hot water
• Industrial facilities – process heating or maintaining temperature in storage areas
• District heating – transferring heat from a central plant into building air systems

Typical Features

• Heat exchanger core (finned coils or plate type)
• Casing or housing for airflow control
• Connection points for hot water, steam, or other heating fluid
• Fans or ductwork connections (in forced-air setups)
• Access panels for cleaning and maintenance

Repair and Maintenance Tasks

• Cleaning the heat exchanger surface to maintain efficiency
• Checking for and repairing leaks in coils or piping
• Replacing corroded or damaged fins or tubes
• Inspecting and servicing fans, dampers, or duct connections
• Testing control valves and sensors

Related Devices

• Boiler – supplies hot water or steam to calorifers in many systems
• Furnace – another type of heating system used in HVAC
• Air Handler

Additional Information
The term calorifer is more common in European and marine contexts; in some regions, similar devices may be called air heaters, fan coil units, or heat exchange coils. While their specific construction varies, the operating principle remains the same: transferring heat from one medium to another.
