Pipes for Water Underfloor Heating Systems

Hydronic icon

Warmup systems come with a choice of 3 pipe types; PEX-A, PE-RT and PE-RT/AL/PE-RT. This choice guarantees that you have the best possible system, tailored to your specific installation and budget.

Warmup PEX-A hydronic pipe carries a Lifetime Warranty for greater peace of mind. All other pipes carry a 50 year Warranty. Our unique SafetyNet™ Installation Guarantee means that should you accidentally damage the pipe on site, Warmup will exchange it free of charge.

Warmup Pipes for Water Systems

PEX-A-Pipe

The Warmup PEX-A Pipe is formed as a single extrusion with an adhesive layer and EVOH oxygen barrier.

View Product

PE-RT-Pipe

The PE-RT pipe is a 5 layer extrusion of polyethylene of raised temperature resistance.

PEX-A Pipe

The Warmup PEX-A Pipe is formed as a single extrusion with an adhesive layer and EVOH oxygen barrier.

E

Oxygen barrier

Encasing the PE-Xa completely, the adhesive layer prevents oxygen entering the system via the pipework.

E

Easy to lay

Flexible and light, the pipe is easy to lay down.

E

Corrosion free

The coatings stop oxygen from entering via the pipework minimising the risk of corrosion to the system.

The oxygen barrier is required to prevent ingress of oxygen which will fuel corrosion within the system. The PEX-a pipe is able to withstand higher pressures, is more kink resistant and considerably more flexible than competing Pex-pipes. This means an easier installation for the installer.

The oxygen diffusion barrier encases PEX-a completely, preventing the entry of oxygen into the heating system via the pipe work. The tough outer layer is designed to withstand the rigours of surrounding workloads, ensuring that the oxygen barrier remains intact. This significantly reduces the risk of corrosion within the entire system.

PEX-a pipe is what we recommend at the heart of all our systems because it is strong, flexible, kink resistant and comes with our best warranties, guaranteed.

AL/PE-RT Pipe

The PE-RT/AL/PE-RT pipe is a 5 layer composite pipe, incorporating layers of PE-RT and adhesives, encasing an aluminium core.

E

Oxygen barrier

The aluminium core prevents oxygen entering the system via the pipework.

E

Easy to lay

PE-RT can hold and maintain its shape, when formed by hand.

E

Corrosion free

The coatings stop oxygen from entering via the pipework minimising the risk of corrosion to the system.

The aluminium core acts as the oxygen barrier, preventing corrosion within the system from oxygen that would otherwise enter via the pipework. The aluminium core also allows the pipe to be positioned and shaped by hand, to maintain this shape.

This means that the pipe requires less overall securing to the subfloor or insulation and is less prone to sagging where it is unsecured.

PE-RT Pipe

The PE-RT pipe is a 5 layer extrusion of polyethylene of raised temperature resistance.

E

Oxygen barrier

The inner layer of PE-RT prevents oxygen entering the system via the pipework.

E

Easy to lay

AL/PE-RT can hold and maintain its shape, when formed by hand.

E

Corrosion free

The coatings stop oxygen from entering via the pipework minimising the risk of corrosion to the system.

This type of pipe is ideal in situations where there is an absolute guarantee that temperatures above 70°C cannot be generated. This cost-competitive pipe is ideal for all types of installations.

The oxygen diffusion barrier encases the inner layer of the PE-RT pipe completely, preventing the entry of oxygen into the heating system via the pipework.

The tough outer layer is designed to withstand the rigours of surrounding workloads, ensuring that the oxygen barrier remains intact. This significantly reduces the risk of corrosion within the entire system.
