  • Soft start relays
  • Prepared for the configuration of four different
    installation systems
  • Display of the refrigerant temperature

NIBE FIGHTER 1140 is a ground source heat pump for heating single and multifamily houses and industrial buildings. The NIBE FIGHTER 1140 is a versatile product with advanced control equipment. The control is also prepared for bivalent heating mode in combination with an oil or gas-fired boiler. This heat pump type is available in the output range of 5 to 17 kW in nine versions. A cartridge heater is fitted in the factory installed electrical cartridge with 3 x 3 kW for 3 x 400 V and 3 x 2 kW for 230V.

The efficiency of the NIBE FIGHTER 1140 is high, thanks to a highly efficient compressor in a well-dimensioned refrigerant circuit. This results in the considerable coefficient of performance (COP) of 5,0 at 0 °C incoming cooling medium temperature and 35 °C outgoing heating medium temperature (excluding circulation pumps).

The NIBE FIGHTER 1140 is designed with the compressor and the refrigerant unit housed in a separate enclosure for easier servicing. As a result the compressor features double sound-proofing, leading to very low noise levels. Circulation pumps and flexible hoses are already built-in. The heat source and heating circuits are connected at the top of the unit for ease of installation. Dirt filters are also included in the contents of delivery.

The unit can be connected to a low-temperature distribution system such as radiators, convectors or underfloor heating/wall mounted heating.

The NIBE FIGHTER 1140 is fitted with a microprocessor to ensure optimal and safe operation. Clear information about status, running time and all essential temperatures in the heat pump is presented on a two-line LCD display. This means that external plant thermometers are not necessary.

The complete NIBE FIGHTER 1140 is enclosed in a robust frame and thanks to sturdy outer panels and effective sound insulation the unit is so quiet, that it does not have a negative effect on living comfort. To ensure simple installation and easy service most panels can easily be removed.

The following docking options are available:

  • Direct connection to a low-temperature radiator/underfloor heating system. The flow temperature is automatically matched to the actual outside temperature. Hot water can be heated in a separate water heater (type NIBE VPA) via a changeover valve.
  • Docking to an existing oil/gas/wood-fuelled boiler or accumulator tank with water heater.

NIBE FIGHTER 1140 can be installed in different ways.

The temperature of the heating system must be taken into account, because the upper temperature limit of heat pumps is lower than that of for instance oil or gas-fuelled boilers.

Electrical cartridge (1-phase or 3-phase) is installed in the heat pump. Room sensors, hot water control and add-on units are available as accessories.

It is possible to cool via the heat source on warm summer days (free cooling).
