Unit heater HC15-3S – compact size, outstanding performance

Choosing the right unit heater is crucial for both home workshop owners and commercial spaces such as car workshops or retail premises. The ideal solution should combine high performance, energy efficiency and application flexibility.

The HC15-3S meets all these requirements thanks to innovative technical solutions, including a two-row heat exchanger, an integrated fan, and three air outlet configurations. It is a unit that performs equally well in a small workshop as it does in professional environments.

Two-row heat exchanger – more power, smaller size

The key feature of this unit heater is its two-row heat exchanger. This advanced design provides a significantly larger heat transfer surface, allowing the air to absorb more thermal energy.

In practice, this means high heating output in a compact casing, making the HC15-3S effective in both small spaces and larger workshops. A home user can comfortably heat a garage, while an automotive workshop can warm its working area without sacrificing valuable space.

Integrated fan – higher efficiency, quieter operation

The innovative integrated fan design ensures improved airflow and minimises pressure losses. Air is drawn perpendicular to the fan’s axis of rotation, which significantly increases overall efficiency.

With an impeller diameter of 300 mm and the use of energy-efficient components, the unit achieves a very low power consumption of just 80 W. At the same time, it operates exceptionally quietly, which is essential both in residential environments and in commercial spaces where acoustic comfort is just as important as performance.

ABS air louvres – durability and reliability

Another advantage of the HC15-3S is the use of air louvres made from ABS plastic. Thanks to the material’s rigidity and high strength, the risk of thermal deformation is minimised, resulting in a longer service life.

This is particularly important in car workshops and retail environments, where the unit heater may be subjected to intensive, long-term operation.

Three air outlet options – tailored to user needs

The HC15-3S is available with three different air outlet configurations, allowing the unit to be precisely adapted to individual requirements:

• Unit heater with adjustable louvres – ideal for precise air direction control. Perfect when heat needs to be directed to a specific area.
  
• Unit heater with diffuser – ensures even heat distribution, maintaining a consistent temperature throughout the space.
  
• Unit heater with 360° outlet attachment – guarantees uniform distribution of warm air in all directions, making it an excellent solution for larger spaces where heat must reach every corner.
  

Summary

The low pressure hot water unit heater HC15-3S is a combination of modern technology and practical design. The use of a two-row heat exchanger, integrated fan, durable ABS components, and a choice of three air outlet variants makes it a versatile solution for both residential and commercial applications.

Its low power consumption, quiet operation, and high heating efficiency make the HC15-3S an ideal choice for anyone looking for a reliable and efficient heat source.
