Public building heats (and cools) with environmental energy instead of oil

The heat supply should be sustainable and independent of fossil fuels. The gymnasium, the music venue, the workshops and the community rooms are to be heated with a flow/return temperature of 45°C/35°C. The classrooms on the upper floor will be fitted with a new ceiling heating/cooling system, which will be operated at a temperature of 35°C/30°C. A further heating circuit was created to heat the kindergarten and a new community hall.

A system solution was found with three highly efficient LA 60S-TUR heat pumps in monovalent operation for heating and cooling with a heat output of 120 kW at A -7/W35. Heat is transferred via underfloor heating or, on the upper floor, via ceiling heating, divided into several heating circuits. Hot water is provided by three parallel buffer tanks of 1000 litres each and a 500 litre hot water tank with fresh water station.

• Intelligent control via WPM Touch Master with intuitive touch display, which allows cascading of up to 14 heat pumps
   
• Six output levels enable needs-based adjustment: efficient use depending on the actual heat requirement and the use of the building (e.g. school holidays)
   
• WPM Touch Master allows flexible and up-to-date monitoring and adjustment of the system through remote access and remote monitoring
