How does a heat pump hot water (HPHW) system work?
The Sanden Eco® Plus heat pump hot water (HPHW) system operates like a refrigerator in reverse. It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the ambient air passes through the evaporator (note: even air below 0 º C contains heat energy) and is absorbed by a natural refrigerant, R744 (aka CO2), which is ozone friendly and does not significantly contribute to global warming compared with most other refrigerants (older style refrigerants have thousands of times more global warming impact for the same amount of gas, when compared with CO2).
The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank.

Error Codes for Sanden Heat Pump G4 GAU-A45HPC
The HP will display an error code if it is unable to function normally.
Error codes are indicated by a red LED on the control panel. The control panel is visible via a small window at the right side of the heat pump and it can be accessed by removing the heat pump top cover (4 screws).
After a component is replaced or the inspection is completed, cycle power to the unit several times to confirm the error does not re-occur.
Below is the list of the error codes. If the corrective action does not solve the error problem, a malfunction of the PCB valve is highly likely.Error

Why does the Sanden Eco® Plus use CO2 as its working gas? Isn’t CO2 a greenhouse gas and therefore harmful to the environment?
Why does the Sanden use CO2 as its working gas, what is the benefit?
- There is far less environmental impact (i.e. No ozone layer depletion and minimal global warming) than other commonly used refrigerants, should the system leak.
- There is a much higher efficiency, thereby allowing more heat to be transferred to the water, for less energy used (i.e. Excellent thermodynamic ability).
Isn't CO2 a greenhouse gas and therefor bad for the environment?
While it is true that Carbon Dioxide (CO2) is a greenhouse gas it has a Global Warming Potential (GWP) of 1. Whereas refrigerant gases in other heat pumps can have GWP of over 10,000, which means if they leak to the atmosphere they contribute 10,000 times more to global warming compared with the refrigerant gases used in a Sanden Eco Plus.
The table below shows the GWP for some common refrigerant gases (note: GWP must include a time interval over which the greenhouse gases act, in this case 100 years)
Our system utilizes less than 1 kg of R744 (CO2) as a refrigerant contained in a closed system at the factory. The installer does not need to charge the heat pump on site.
- There is far less environmental impact (i.e. No ozone layer depletion and minimal global warming) than other commonly used refrigerants, should the system leak.
