Manufactured with five-layer modern PERT, PEX and aluminium, Multipipe Multilayer Composite Pipe (MLCP) is the high-quality and secure solution installers are turning to as an alternative to copper and push-fit piping (read more here). Complete with our highly technical support team, there is nothing better on the market than Multipipe’s offering.

Over the last few years, we’ve helped numerous installers to move to MLCP, resulting in faster, cleaner, more secure, and more profitable installations. Find out more about Multipipe’s MLCP here.

Press-fit plumbing uses a specialised tool to create secure connections between pipes and fittings. Instead of soldering or brazing, a pressing action creates a permanent, leak-proof joint.

Faster installation: Press-fit connections take seconds compared to soldering or brazing, saving time and labour costs.

Increased safety: Eliminates risks associated with open flames and hot work permits.

Easier to learn: Requires less skill than soldering, making it ideal for apprentices but also for professional plumbers looking to expand their skills in the industry.

Reliable connections: Press-fit joints are known for their strength and durability.

Contact Multipipe for more information on our press-fit fittings and MLCP products! Call our friendly team on 01245 227630, or email our technical team: technical@multipipe.co.uk.

We have a range of blogs, technical guides and videos in our knowledge base too.

Underfloor heating is a modern and efficient way to heat your home and comes with many benefits. At Multipipe, we specialise in providing high-quality underfloor heating solutions for homes and businesses.

Underfloor heating works with multi-layered composite pipe (MLCP) by circulating hot water through the pipes embedded within the floor structure. Here’s a breakdown of the process:

The System:

  • Heat Source: A boiler, heat pump, or another heating source generates hot water.
  • Manifold: This central hub distributes hot water to individual heating circuits.
  • MLCP Pipe: The hot water travels through the MLCP pipes laid out in a specific pattern beneath the floor.
  • Heat Transfer: The pipes transfer heat to the surrounding floor material (concrete, screed etc.) which then radiates warmth upwards into the room.
  • Thermostat Control: A thermostat regulates the water temperature and ensures the desired room temperature is maintained.

Find out more about how underfloor heating works with MLCP in our blog.

Durability: MLCP is a robust material that can withstand high temperatures and pressures typically used in underfloor heating systems.

Flexibility: The pipes are flexible enough to navigate around obstacles and corners during installation.

Oxygen Barrier: The multi-layered construction provides a strong barrier against oxygen diffusion, preventing corrosion within the system.

Leak Resistance: The press-fit connections used with MLCP minimise the risk of leaks compared to traditional methods.

Insulation: Some MLCP pipes come pre-insulated, reducing heat loss during water circulation.

Efficient Heat Distribution: MLCP transfers heat effectively, ensuring even warmth throughout the floor.

Faster Installation: Compared to traditional copper pipes, MLCP can be installed more quickly due to their flexibility and easier connection methods.

Long-lasting System: The durability of MLCP contributes to a reliable and long-lasting underfloor heating system.
