Fully Certified Renewable Installer
Providing confidence in home-grown energy

Water Source Heat Pumps (WSHPs) provide one of the most efficient methods of heating and cooling available today by harnessing the stable temperature of nearby water sources.
These systems are especially suitable for properties with access to lakes, rivers, or underground aquifers, offering consistent and reliable performance year-round. Whether for a large estate, a commercial facility, or an industrial complex, WSHPs deliver significant energy savings and are a smart investment for anyone focused on sustainability.
Greenfields specialises in designing and installing customised WSHP systems that meet the unique needs of your property, ensuring maximum efficiency and sustainability.
How Water Source Heat Pumps Work

Water Source Heat Pumps operate by circulating a mixture of water and antifreeze through pipes submerged in a nearby body of water. This mixture absorbs the stable heat from the water, which is then compressed and used to heat your property. In the summer, the process can be reversed to provide cooling.
The consistent temperature of water sources ensures that WSHPs deliver high efficiency and reliable performance throughout the year, making them one of the most effective heating and cooling solutions available.


System Types and Their Benefits
At Greenfields, we understand that every property is unique, which is why we offer several types of water source heat pump systems to suit different needs:
- Open-Loop Systems
These systems use water directly from the source, providing the highest efficiency. Ideal for properties near substantial water bodies, open-loop systems offer unmatched energy savings but require specific site conditions. - Closed-Loop Systems
Suitable for properties with access to smaller or protected water sources, closed-loop systems circulate a mixture of water and antifreeze through submerged pipes to extract heat without direct water exchange. - Hybrid Systems
Hybrids combine elements of open and closed-loop systems and can be tailored to properties with varying site conditions, ensuring optimal performance and flexibility.
Benefits of Water Source Heat Pumps
- High Efficiency
WSHPs are among the most efficient heat pump systems, providing substantial energy savings compared to traditional heating and cooling methods. - Year-Round Performance
The stable temperature of water sources ensures consistent heating and cooling, regardless of seasonal changes. - Sustainability
WSHPs use a renewable energy source, reducing your carbon footprint and contributing to a greener future. - Government Incentives
Installation of WSHPs is eligible for various government grants, making them a financially attractive option.

Ideal Applications for Water Source Heat Pumps
Water Source Heat Pumps are ideal for properties with easy access to natural water sources, including large residential estates, commercial properties, hotels, resorts, and industrial facilities. They are particularly well-suited for projects prioritising energy efficiency and sustainability, offering a reliable and eco-friendly heating and cooling solution.
Choosing the Right System for Your Property
Selecting the right type of water source heat pump system is crucial to ensuring optimal performance and cost savings. At Greenfields, our team conducts thorough site assessments and consultations to help you choose the system that best fits your property’s specific requirements. We take into account factors such as water availability, site conditions, and energy needs to design a system that maximises efficiency and long-term value.
Running Costs and Efficiency
Water Source Heat Pumps are highly efficient, often producing five to six times the energy they consume (Coefficient of Performance, or CoP). This makes them one of the most cost-effective heating and cooling solutions, particularly for larger properties or commercial applications. Additionally, WSHP installations are eligible for the Boiler Upgrade Scheme (BUS), providing further financial benefits.
Considerations for Installation
- Water Source Availability:
A consistent and reliable water source is essential for the successful operation of a WSHP. Greenfields will assess your property to determine its feasibility and the best installation approach.
- System Size:
The size of the required system depends on your property’s energy demand and the available water source. Our team will provide a detailed assessment and recommendation to ensure optimal performance.
- Regulatory Compliance:
WSHP installations may require specific permits or compliance with environmental regulations, particularly for open-loop systems. Greenfields handles all regulatory requirements to ensure a smooth installation process.
Our team at Greenfields will guide you through these considerations during our detailed site assessment, ensuring the best possible system design for your property.
