The CO2 heat pump is a recently developed and more efficient alternative than traditional systems to produce DHW. The CO2 heat pump technology is capable of producing up to 4 kW of thermal energy from 1kW of power supply (from electricity), while a conventional gas or oil boiler can only produce less than 1 kW of thermal energy from 1kW of power supply (from fuel).
Energy savings can reach up to a 78% compared to a standard gas boiler (90% efficiency)
Non-contaminant and high GWP refrigerant gas is used
High working pressures
Minimum evaporation temperature: – 56°C
Condensation temperature maximum: 31°C
More expensive facilities operating with conventional refrigerants
Heavier than air. In case of escape, the CO2 is coupled to ground level and displaces air
In case of leaks, there is no warning based on smell (odourless)
Lower life cycle maintenance/repair costs.
Payback estimated: 3-7 years, depending on the system configuration and other issues.
