What is the output temperature of a water to water heat pump?

The output temperature of a Water to Water Heat Pump varies depending on the model and application, but typically ranges from 35°C to 60°C for residential hot water and heating, with higher-end commercial and industrial models capable of producing up to 120°C or even steam for specialized processes. The specific output temperature is determined by the heat pump's design and the requirements of the system's heating.

Residential Applications

• Domestic Hot Water (DHW):
  Most residential heat pumps can heat water to a sufficient temperature for hot water storage, typically between 50°C and 60°C.
• Space Heating:
  For heating systems like underfloor heating, lower output temperatures are suitable, around 35°C to 55°C.

Commercial and Industrial Applications

• Commercial Buildings and District Heating:
  Medium to high-temperature units can provide 60°C to 85°C for commercial purposes.
• Industrial Processes:
  Ultra-high-temperature heat pumps are designed for industrial applications, capable of producing water or even steam at temperatures of up to 120°C.

Factors Affecting Output Temperature

• System Design:
  The intended use and design of the heat pump determine its maximum achievable output temperature.
• Heating Application:
  Higher temperature requirements, such as those for industrial processes or older radiators, will require different heat pump units than those for low-temperature heating like underfloor systems.
• Efficiency Considerations:
  While heat pumps can often be pushed to higher temperatures, their energy efficiency (COP) decreases significantly at these high temperatures.
