The innovative combination of a standard condensing heating unit with a R744 (CO2) heat pump cycle driven by thermal compression instead of mechanical work sums up to a condensing heating unit supplying 20kW heat at up to 65°C and a seasonal gas utilization (SGUE) of up to 200%. This heating system hence comes with up to 50% renewable ambient thermal energy available all year round.
The heat pump cycle is driven by external combustion heat. It can be operated with what ever typeof gas: natural, liquid, biogas, fluegas or even hydrogen. Also liquid fuels like oil or methanol might be used in the future.
The development was started in the year 2004 and supported by strong partners holding stakes in the gas sector. The market entry will take place in mid 2018.
