FAQs on geothermal pipes & fittings.
Why are PE pipes ideal for geothermal heating systems?
PE pipes are strong, flexible and resistant to both high pressures and low temperatures. Their durability makes them perfect for underground installations, where they provide consistent performance for decades.
How does a geothermal heating system work?
Geothermal systems use buried loops of PE pipe to capture the natural heat stored in the ground. This heat is transferred via a heat exchanger to warm central heating systems in homes or buildings.
What types of pipes do you offer for geothermal installations?
We offer a range of PE black pipes in straight lengths and coils, as well as specialist ground loop systems, to suit a variety of projects
Are your products eco-friendly?
Yes, our PE pipes are 100% recyclable, and we use sustainable manufacturing practices to minimise environmental impact. Geothermal heating systems themselves are a renewable energy solution, helping to reduce reliance on fossil fuels.
Do you supply fittings and accessories for geothermal systems?
Yes. We provide a full range of electrofusion fittings, distribution chambers, and manifolds to complement our pipes, ensuring a seamless and efficient system installation.
What are the benefits of geothermal heating?
Geothermal heating offers free, renewable energy from the ground, reducing energy bills and carbon emissions. It’s a low-maintenance, long-lasting solution that provides reliable heating all year round.
