Mineline and Geothermal Heat: Advancing Sustainable Energy Solutions

At IPS Flow Systems, we are committed to providing top-quality products and exceptional service to meet your geothermal project needs. Mineline, developed by AGRU Kunststofftechnik GmbH , is an advanced piping system that stands at the forefront of geothermal heat applications and other scenarios demanding high resistance to abrasion. Its unique multi-layer construction not only enhances durability but also ensures efficient thermal management. These features make Mineline an ideal choice for geothermal systems, where long-term performance and reliability are paramount.

Key Features of Mineline

  1. Abrasion Resistance: Mineline’s robust multi-layer design significantly extends the lifespan of the piping system, reducing the need for frequent replacements and maintenance.
  2. Thermal Stability: The system’s white outer layer reflects sunlight, minimising thermal expansion and ensuring consistent performance.
  3. Operational Safety: Mineline's design includes safety margins against pressure surges and water hammer, safeguarding the entire system.


  • Size Range: 63mm to 630mm
  • Pressure Ratings: SDR 17 and SDR 11

Geothermal Heat Applications

Geothermal heat pumps (GHPs), also known as ground-source heat pumps, are highly efficient systems that use the earth’s constant underground temperature for heating and cooling. GHPs can cut energy bills by up to 65% compared to traditional HVAC systems, making them an attractive option for both residential and commercial buildings. Mineline pipes are crucial in these systems, providing reliable and efficient transport of heat-carrying fluids.

Benefits of Geothermal Systems

  1. Energy Efficiency: GHPs use significantly less energy compared to conventional heating systems. ENERGY STAR-certified geothermal heat pumps, for instance, use up to 72% less energy than standard air-conditioning equipment (British Geological Survey) (House of Commons Library).
  2. Environmental Impact: By reducing carbon emissions, GHPs contribute to the decarbonisation of the heating sector, a crucial step in addressing climate change (Eden Project) (British Geological Survey).
  3. Longevity and Reliability: Components of geothermal systems, including the ground loops made with Mineline pipes, can last over 50 years, offering long-term cost savings and reliability (Durham University) (GOV.UK).
  4. Versatility: Suitable for various climates and applications, geothermal systems can provide heating and cooling across diverse geographical locations (Energy.gov) (New Scientist).

The UK Context: Harnessing Geothermal Energy

The UK has vast potential for geothermal energy, particularly in regions with historical mining activities. Projects like the Eden Geothermal in Cornwall demonstrate the feasibility and benefits of geothermal heat. This project, with a well depth of over 4,800 meters, supplies heat to the Eden Project and adjacent facilities, showcasing the application of geothermal energy in sustainable development (Eden Project).

Additionally, the British Geological Survey has identified significant geothermal resources in former coal mines, which could heat millions of homes. Schemes like the Gateshead mine water heat project highlight the practical implementation of geothermal energy, contributing to carbon savings and energy security (British Geological Survey) (GOV.UK).

UK Government Support and Policy

The UK government recognises the importance of geothermal energy and supports its development through various initiatives and funding schemes. For instance, the Renewable Heat Incentive (RHI) provided financial subsidies to encourage the adoption of renewable heating technologies, including geothermal systems (House of Lords Library). Additionally, the Heat Networks Investment Project (HNIP) aims to expand the construction of heat networks, promoting the use of geothermal energy for heating homes and businesses (GOV.UK).

In recent years, significant investments have been made to explore and develop geothermal resources. The North East Local Enterprise Partnership, in collaboration with Arup, has produced a white paper outlining the potential of deep geothermal energy to contribute to the UK’s net zero objectives (British Geological Survey).
