    Industry Leaders in Ground Source Heat Pump Solutions

    With over 15 years of experience, Pure Thermal has established itself as a leading provider of industrial and commercial ground source heat pumps. Their commitment to high-performance, low-carbon solutions ensures that businesses benefit from efficient, flexible, and sustainable heating systems tailored to meet the demands of each application. Understanding that industrial and commercial projects require both reliability and adaptability, Pure Thermal offers a comprehensive range of ground source heat pumps. Designed to optimise energy efficiency and carbon savings, these systems provide an advanced alternative to conventional heating technologies.

    High-Performance Ground Source Heat Pumps

    Pure Thermal supplies ground source heat pumps on a supply, commission, and maintenance basis, ensuring seamless integration from initial specification to long-term operation. Their industrial and commercial heat pumps can deliver temperatures up to 120°C, making them suitable for both retrofit projects and new-build applications. With capacities ranging from 30kW to over 3000kW, Pure Thermal’s ground source heat pumps operate using low global warming refrigerants, offering businesses an environmentally responsible solution that reduces energy costs and emissions. These systems provide year-round heating, optimising performance even in challenging operating conditions.

    Flexible System Configurations for Maximum Efficiency

    To meet diverse application requirements, Pure Thermal’s ground source heat pumps are available in single-stage (Monobloc) and two-stage system configurations. The Monobloc Pure Thermal Commercial Ground Source Heat Pump can achieve an output temperature of 95°C from a 0°C source temperature, eliminating the need for a cascade or two-stage system for medium-capacity applications. For large-scale projects, the Pure Thermal PLUS SO System delivers a two-stage ground source heat pump solution with single-system control and operation. This system integrates both a ground source heat pump and a water-to-water heat pump, creating a high-capacity, next-generation heating system that provides enhanced thermal efficiency for large industrial and commercial applications.

    Dual-Source Heat Pump Technology for Increased Efficiency

    Pure Thermal’s industrial ground source heat pumps can be configured as dual or multiple-source systems, further improving operational efficiency. These units can operate as a traditional geothermal heat pump while also utilising an alternative heat source for increased energy savings. For example, if a facility has a cooling requirement during the heating season, the heat pump can draw from a 14°C chilled water return rather than relying solely on lower-temperature ground sources. This optimises energy efficiency, reduces electricity consumption, and enhances performance consistency across varying conditions.

    Expert System Design and Heat Pump Verification Service

    Selecting the most suitable system design is critical to achieving optimal performance, and Pure Thermal offers a Heat Pump Ready Verification Service to help businesses identify the most efficient and cost-effective solution. Rather than focusing solely on heat pump type, this service evaluates the application’s specific requirements to recommend the best low-carbon heating approach. Pure Thermal’s team of industry specialists ensures that every project benefits from expert advice and tailored recommendations. Businesses looking to transition to high-performance, sustainable heating systems can rely on Pure Thermal for cutting-edge technology, technical expertise, and long-term efficiency.

    Understanding Ground Source Heat Pumps

    Ground source heat pumps (GSHPs) harness thermal energy from the ground to provide efficient heating and cooling solutions. While high ground temperatures can enhance performance, the installation process can involve significant civil engineering costs, particularly when borehole drilling is required. There are three primary methods of ground heat collection, each offering distinct advantages depending on site conditions and project requirements.

    Horizontal Collectors

    A horizontal collector consists of pipes laid at depths of 1.2 to 1.5 metres, running horizontally across the ground. At this shallow depth, most thermal energy is derived from solar and surface heat, rather than deep geothermal sources. While this method can be cost-effective, its efficiency is lower than deeper collection systems, as usable ground temperatures typically start at 15 metres below the surface.

    Closed Loop Boreholes

    A closed-loop borehole system uses flow and return pipes within a single borehole, typically drilled to depths of 150 metres or more. A water/glycol mixture circulates through these pipes, reaching a U-bend at the base before returning to the heat pump. The borehole is filled with a grout material that enhances heat transfer, allowing the system to extract energy from the surrounding ground efficiently. Multiple boreholes can be connected in an array to provide sufficient capacity for larger applications.

    Open Loop Boreholes

    An open-loop borehole system extracts groundwater from an aquifer, circulating it through the heat pump before returning it to a separate borehole. These systems offer high efficiency due to the consistent temperatures of aquifer water, making them particularly effective in areas with suitable groundwater conditions. Additionally, open-loop systems can utilise redundant mine workings as a thermal energy source, tapping into naturally occurring underground water reserves that maintain stable and usable temperatures. This provides a viable and sustainable heating solution in areas with historic mining activity.

    Ground source heat pumps, whether horizontal or borehole-based, provide a low-carbon, high-efficiency alternative to traditional heating systems. Their ability to deliver reliable and consistent heating performance makes them an ideal solution for industrial, commercial, and large-scale residential applications.

    Applications of Geothermal Heat Pumps

    Geothermal heat pumps offer versatile and efficient heating solutions across a range of applications. Whether using horizontal collectors, closed-loop boreholes, or open-loop boreholes, these systems can be tailored to suit the specific energy demands and site conditions of a project. Each system provides unique advantages depending on ground conditions, space availability, and budget constraints. In projects where extensive groundworks are feasible, a primary ground source collector-driven heat pump system may be the most effective option. However, in cases where reducing civil engineering costs is a priority, geothermal heat pumps can be configured as air/ground dual-source systems, optimising efficiency while minimising installation complexity.

    By offering flexible configurations, geothermal heat pumps provide an ideal low-carbon heating solution for industrial facilities, commercial buildings, residential developments, hospitals, and large-scale district heating projects.
