Project description

We proudly present you our hybrid heating installation model that uses ROBUR GAHP-A-HT S Gas-fired condensing absorption heat pump. Installation is designed to generate heat for heating purposes and domestic hot water preparation in a single house. Moreover the installation will serve as a test-training stand certifying functional possibilities of ROBUR GAHP-A-HT S Gas-fired condensing absorption heat pump in real-time operation in climatic conditions with temperatures falling below zero (down to -30°C) which determines the limits for heat pump operation.
