SANYO’s Pioneering New CO2 Heat Pump System 

The UK’s first installation of SANYO’s ground-breaking new ECO carbon dioxide-based heat pump heating system is now up and running at Oceanair’s Bristol facility. The new refrigerant-based technology harnesses an advanced air-to-water heat pump to deliver low-cost hot water for use in heating and domestic hot water in residential and small commercial premises.



The new refrigerant-based technology harnesses an advanced air-to-water heat pump to deliver low-cost hot water for use in heating and domestic hot water in residential and small commercial premises.

- Water up to 65ºC—hot enough for showers and baths without the need for electic booster heater keeping energy costs and emissions low. 

- 50% less carbon emissions than comparable gas –fired boilers 

- World’s first two stage rotary compressor operating on R744 and can operate at ambient temperatures as low as -25ºC. 

- Inverter controlled high performance direct current unit delivers COPs of up to 3.75. 

- System consists of an outdoor heat pump unit linked to an indoor unit containing a heat exchanger and thermal store. 

- System supplies hot water for washing and can be directly connected up to radiators or an underfloor system for space heating. 

- System comes pre-charged with refrigerant and requires only water and electrical connections. 

- The ECO has a sophisticated control system that simultaneously delivers water at different temperatures for different uses.
