Heat Pump Radiators

Hydronic fan coils designed for low-temperature heating and high-efficiency cooling with heat pump and chiller systems.

PowerKon LT is the lowest profile hydronic fan coil designed for low-temperature hot water systems. It delivers efficient heating and cooling when connected to air-to-water or water-to-water heat pumps, chillers, or other hydronic HVAC systems. It is ideal for both new construction and retrofit projects to replace conventional high-temperature heating systems.

  • Heating and cooling with low-temperature hot water and chilled water systems

  • Hydronic system with water distribution throughout the building – refrigerant remains inside the heat pump or chiller. 

  • Fast response times thanks to powerful and efficient EC fans
  • Exposed wall-mounted with very low-profile casing
  • Optionally recessed in-wall (6” stud) with front cover panel

Highlights

Heat Pump Efficiency

PowerKon LT is actually designed for hydronic low-temperature heating systems with supply temperatures as low as 95°F (35°C).   A 95 °F low-temperature system maximises the efficiency of the heat-pump and therefore the overall system. 

Easy Conversion

Fan-assisted terminal units are ideally suited for use in existing buildings, as the switch from an oil or gas heating system to a heat pump is easily achievable. Compared to infloor heating, low-temperature fan coils offer two decisive advantages: They are quick and easy to install and connect directly to existing hydronic piping – with very little disruption to the space.

Effective Cooling

In addition to the energy-efficient heating function, hydronic fan coils provide sensible cooling using chilled water supplied by a reversible heat pump or chiller. Depending on the insulation of the existing piping system, dry or wet cooling can be realized.

Quiet Operation

Low-profile hydronic fan coils provide heating and cooling with fan assistance. The use of EPP (expanded polypropylene) ensures optimal airflow, enabling maximum air volumes at low sound power levels. This is why hydronic fan coils can be installed in office spaces and living areas – even in bedrooms.

Our Product

PowerKon LT

  • Heating
  • Cooling
PowerKon LT is a compact 2-pipe hydronic fan coil that provides efficient space heating and cooling using low-temperature hot water and chilled water. It is specifically optimized for modern heat pump and chiller systems.

The Heat Pump System

The temperatures of the heating water are crucial for the efficient operation of any heating system. How warm this water needs to be depends on the chosen combination of heat generator and heat consumer. The basic principle is always the same: A heat generator supplies warm water to room units, and the heat consumers use the warm water to temper the rooms.

If an oil or gas boiler is replaced by a heat pump as the heat generator, low system temperatures are recommended to keep operating costs low at high performance. Fan-assisted convectors are recommended as heat consumers, as they quickly achieve 3-4 times the output in low-temperature operation compared to conventional radiators.
