Wien Spittelau High Temperature Heat Pump

THERMAFLEX DEMO PROJECT: Use of the heat from the flue gas by means of a high-temperature heat pump

Wien High Temperature Heat Pump Spittelau

In this project it is planned to use the waste heat from the flue gas condensation of the waste incineration plant in the Spittelau in Vienna as a source for a heat pump and to make a direct feed into the primary district heating network of the City of Vienna possible by incorporating the findings from the test of different operating strategies. The thermal capacity of the planned heat pump is more than 10 MW.

Burn in the best possible way

In the Spittelau waste incineration plant, a modern heat pump based on the Scandinavian model is to use the heat from the flue gas. This saves water, C02 and supplies 10,000 households with heat.
