Water Source Heat Pumps

Fully Certified Renewable Installer

Providing confidence in home-grown energy

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.

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.

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.

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.

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.

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. 

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.

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.

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.

What types of properties are best suited for Water Source Heat Pumps?

Properties with access to natural water bodies such as lakes, rivers, or aquifers are ideal for WSHPs, particularly large residential estates, commercial properties, and industrial facilities.

How does a Water Source Heat Pump compare to other heat pump systems?

WSHPs are generally more efficient than air-source heat pumps and can outperform ground-source systems in terms of CoP, especially in areas with stable water temperatures.

What maintenance is required for a Water Source Heat Pump?

WSHPs require minimal maintenance, typically involving an annual service to ensure efficient operation. Specific maintenance may depend on the system type and the water source’s quality.

Are Water Source Heat Pumps eligible for government grants and incentives?

Yes, WSHP installations are eligible for various government grants and incentives, including the Boiler Upgrade Scheme (BUS), which can reduce the upfront installation cost.

Can Greenfields help me understand which Water Source Heat Pump system is appropriate for my property?

Absolutely. Our team conducts thorough site assessments and consultations to help you choose the best system for your property, ensuring it meets your specific needs and maximises efficiency.
