Gas heat pumps

Regenerative, versatile and economical

With Schwank gas heat pumps, heating and cooling can be carried out in an extremely efficient manner, and moreover, in just one system. Different to electric heat pumps, a gas motor takes over the propulsion of a refrigerant process in a gas heat pump. The gas heat pump requires “gas” as the energy source instead of “electricity” for the generation of heating or cooling. This results in several advantages.

Possible applications for temperature control [heating and cooling] in trade and industry:

  • Halls for the storage of temperature-sensitive goods, e.g. chocolate, cosmetics, hazardous substances, pharmaceutical products
  • Heating and cooling supply in offices, laboratory, research and exhibition
  • Temperature control of buildings with thermal processes, e.g. when using machines in a hall


Your benefits at a glance


During the generation of electricity, approximately 60% waste heat arises in modern gas or coal-fired power plants. The waste heat that arises in the gas motor of the heat pump is used by the device directly on site. It either supports the heat pump process or serves as the additional heat source, e.g. for heating the service water.

Gas - the driving force

The difference between a gas and an electric heat pump is that a gas and not a electricity-operated motor drives the compressor of the refrigerant circuit. Gas heat pumps are used all across the world as an environmentally friendly and efficient solution for the temperature control of buildings. Especially for bigger loads – e.g. in industry or commerce – this technology is extremely advantageous, since it uses the inexpensive primary energy: gas.  
For our gas heat pumps, we rely on Panasonic - one of the leading manufacturers. In 1958, the company developed the first room air conditioner and has continually been making advancements in its “climate control” business segment. Panasonic is an ideal partner as far as gas heat pumps are concerned. When it comes to the development of its gas heat pumps, the company places huge importance on efficiency, dependability and low noise. Thanks to intensive quality controls, the Panasonic heating and cooling systems meet the highest requirements. The gas heat pumps by Panasonic are characterised by their high level on innovation and quality. In combination with the know-how of Schwank in terms of heating and cooling of large-scale buildings, an unbeatable combination of quality and competence arises.

Hot water instead of cooling agent

A heat exchanger integrated into the gas motor heat pump ensures that water pipes can be directly connected to the heat pump. The cooling agent pipework is therefore omitted completely.

Cooling agent: Connection to a ventilation unit [RLT]

Alternatively, the gas heat pump can be connected to a ventilation [RLT] unit. It provides the building with heating or cooling via duct systems. A combination of indoor units and the RLT system is also possible.

Cooling agent: Direct connection of indoor units

Indoor units connected directly to the cooling agent system ensure the heating and cooling distribution within the buildings. Here, no additional heat exchangers are used – the closed system ensures efficient temperature control.

Combination: Hot water and cooling agent

Optionally, an additional heat exchanger can be integrated into the system. For example, an adjacent office or a hot water requirement can be supplied.
