Underfloor heating pipe

Underfloor heating pipes transport warm water to different zones within the system. Made from a combination of layered plastic, UFH pipe has various qualities.
Flexible to allow ease of installation when forming the layout. Corrosion-resistant & durable to ensure the system lasts a long time. Tough to withstand the high pressure and temperature of the system.

Types of underfloor heating pipe

PEX AL PEX pipe is one of the few WRAS-approved pipes on the market. This is our top choice, manufactured with a focus on quality. Made from a 5-layer composite it contains a 0.2 mm thick aluminium core with butt-welded construction. This UFH pipe is energy efficient due to the alloy inner core technology.

PEX AL PEX is easy to install and holds its shape once positioned. It is flexible and is well-suited for various installation requirements. PEX-AL-PEX pipes combine the advantages of enhanced strength and resistance to high temperatures up to 95°C. Available in different lengths, these pipes cater to diverse project sizes. This ensures seamless integration into your underfloor heating system.

Underfloor heating pipe spacing

Spacing is crucial as it impacts heat output. Lower pipe spacing will provide the best heat output however, it increases material and installation costs. Spacing will also affect how quickly the system heats up. Your home’s insulation and specific room requirements determine the optimal pipe spacing.

We recommend a pipe spacing of 150 mm for most properties. Smaller spacing of 100 mm or 125 mm produces a greater output, often paired with a low-temp heat source or a high heat loss area. 200 mm spacing can be used when insulation is of a high standard. This spacing, however, could be inadequate if changing to a lower temperature heat source in the future like an air or ground source heat pump.

Repairing the pipe is possible, depending on the extent and location of the damage. Minor leaks or damages may be repairable using a compression coupling.

Our WRAS-approved PEX AL PEX comes with a 25-year warranty.

The lifespan can vary depending on factors like material quality and installation. Generally, these pipes have a lifespan of 50 years or more, given proper installation and maintenance.

Pipes are made from materials layered in plastic. PEX, PEX-AL-PEX, or occasionally, PERT. These materials are durable, flexible, and resistant to corrosion.

PEX-AL-PEX is our preferred pipe option as it has an aluminium core providing a greater heat output.

The size range for underfloor heating pipes ranges between 12 mm to 20 mm in diameter.

16 mm diameter is a common size for UFH pipes providing efficient heat distribution and is compatibility with various UFH systems. multi

Our UFH pipes measure 16 mm in diameter as they allow longer lengths without compromising performance. They are compatible with our EPS overlay boards.
