What are Air-Source Heat Pumps (ASHPs) and Water-Source Heat Pumps (WSHPs)?

Air-Source Heat Pumps (ASHPs) and Water-Source Heat Pumps (WSHPs)follow the same thermodynamic cycle called the ‘Vapour Compression Cycle’. (Please watch our ‘Heat Pump Knowledge Series’ to learn more about the thermodynamic cycle).

How To Choose Between Air-Source and Water-Source Heat Pumps?

The air source heat pump takes the input of electricity, extracts the heat from the ambient air, and gives hot water up to 90 degrees Celsius. Due to the extraction of heat from the ambient air, the ambient gets cooler. So, if there is a requirement for both hot water and cold air, then the air source heat pump is the solution.

Water source heat pump takes the input of electricity, extracts heat from ambient water or process return water from industrial processes, and gives hot water up to 90 degrees Celsius. Due to the extraction of heat from the water, the water gets cooled in the range 7 to 30 degrees Celsius and this temperature is dependent on the temperature required for hot water. If there is a  requirement for both hot water and cold water, then the water source heat pump is the solution.

Get Both Heating and Cooling

Hot water is generally used in industries for degreasing, for pre-treatment, or for washing machines. In the commercial sector,  it can be used for bathing purposes or in kitchens. Coldwater can be used to reduce the load on chillers and cold air can be used for space cooling where the room temperature has to be brought down. Check out Aspiration Energy’s heat pump solutions.

Environmental and Financial Payback

As both the heat pump types run on the same principle, both run with almost the same efficiency. Both the heat pumps are useful to reduce the CO2 emissions and help industries to reduce their energy bills. Return on investment is high if the existing system is an electric heater or a hot water generator. If you replace them with the heat pump, then the payback period will be less than 1.5 years.
