Water source heat pumps operate by extracting heat from a water source and transferring it to a heating system through refrigeration-based technology. The process involves absorbing thermal energy from the water, cooling the source in the process, and then using the recovered heat to generate high-grade heating for buildings, industrial processes, and district heating networks. These systems offer a reliable and highly efficient way to generate heating with a minimal environmental footprint.
Water sources for these systems vary, providing flexibility in installation and operation. They can utilise under-surface aquifers, rivers, lakes, estuaries, seawater, wastewater, and effluent as their primary heat source. Each of these sources offers unique benefits, with some providing more stable temperatures than others, which improves overall system efficiency.
The key advantage of using water as a heat source is its high thermal conductivity and stable temperatures compared to air. This makes water source heat pumps one of the most efficient renewable heating solutions available. The ability to extract heat from water bodies ensures consistent performance even in colder months, making these systems a practical choice for year-round heating requirements.
Pure Thermal’s water source heat pumps offer exceptional output temperatures, ranging from 35°C to 120°C. Their ability to operate with high source temperatures of up to 60°C ensures that they can meet the demands of industrial processes requiring precise temperature control. With their ability to function efficiently in challenging conditions, these heat pumps are widely used in manufacturing facilities, district heating networks, and large-scale commercial buildings. One of the defining features of these systems is their ability to integrate with multiple heat sources. Dual and multiple-source configurations allow the heat pump to operate using a combination of water, cooling systems, waste heat, and air sources. This capability optimises system efficiency, enabling businesses to minimise energy consumption while maximising heat output.
Pure Thermal’s advanced heat pump technology ensures that businesses can transition from fossil fuel-based heating to renewable alternatives without compromising performance. Their range of water source heat pumps is designed to meet varying application requirements, whether for retrofit projects, new-build developments, or process heating applications.
Pure Thermal provides a range of water source heat pumps designed to offer flexibility in application. These systems are available in both single-stage (Monobloc) and two-stage configurations, allowing businesses to select the most suitable option for their specific heating requirements.
The Monobloc water source heat pump delivers output temperatures of up to 95°C from a 0°C source temperature. This removes the need for a cascade or two-stage system in medium-capacity applications, simplifying installation while maintaining high efficiency. These systems provide reliable heating performance even in low-temperature conditions, ensuring optimal efficiency in commercial and industrial settings.
For large-scale projects requiring higher capacities, the Pure Thermal PLUS SO System offers a two-stage water source heat pump solution with single-system control and operation. This advanced system integrates a water source heat pump with a water-to-water heat pump, delivering enhanced thermal efficiency and meeting the demands of large industrial applications. By combining two heating stages within a single system, this solution ensures seamless heat management while reducing energy consumption.
Water source heat pumps can be configured as dual or multiple-source systems, enhancing operational efficiency by integrating alternative heat sources. Pure Thermal’s advanced dual-source technology enables these systems to switch between different heat sources based on availability, ensuring optimal performance at all times.
For instance, in an industrial facility where cooling is required alongside heating, a water source heat pump can utilise waste heat from a chilled water return system. If the external temperature is 7°C but a cooling process provides a 14°C return flow, the heat pump prioritises the higher-grade heat source, improving efficiency and lowering electricity consumption. By integrating multiple heat sources, these systems ensure that businesses benefit from reduced operational costs and increased sustainability.
Waste heat recovery is another key advantage of Pure Thermal’s water source heat pumps. By capturing excess heat from industrial processes, these systems further enhance energy efficiency, ensuring that no thermal energy is wasted. This ability to recycle heat makes water source heat pumps a preferred solution for businesses looking to optimise their energy use while minimising environmental impact.
Industrial processes and manufacturing facilities rely on water source heat pumps for high-demand heating applications, including material processing, drying applications, and waste heat recovery. Their ability to deliver high-temperature output ensures they meet the needs of energy-intensive industries.
District heating projects utilise these heat pumps to supply efficient heating across multiple buildings. By extracting thermal energy from water sources and distributing it to residential, commercial, and industrial buildings, these systems offer a scalable and sustainable alternative to conventional heating networks.
Every project begins with a comprehensive assessment of site conditions, energy demands, and available heat sources. By analysing these factors, Pure Thermal develops optimised system designs that maximise efficiency while minimising installation and operational costs. Their technical expertise ensures that the correct heat pump configuration is selected for each application.
