説明
One Coil, One Run, No Joints In The Wall. Every joint in a heating or water circuit is a place where a system can fail, and the older the building the more joints it has hidden behind plaster. This is a 656 foot coil of aluminium-plastic composite pipe, which means a whole floor loop or a long supply run can be pulled as a single unbroken length and buried without a fitting every four metres.
The construction is the reason it behaves the way it does. A PEX inner and outer layer is bonded around an aluminium core, so the pipe keeps the flexibility of plastic while the metal layer holds its shape when bent and blocks oxygen diffusion into the circuit. It tolerates minus 40 to 95 degrees Celsius, with a working temperature of 70 degrees, which covers radiant floor heating, domestic hot and cold lines, and the return legs of a heat pump system.
The dimensions are 5/8 inch, or 16 mm, outside diameter with a 2 mm wall, and the smooth internal bore keeps pressure loss low across a long run. The coil ships with a pipe cutter, a rounding tool and 20 clamps, so the installation does not stall waiting on consumables. It is CE certified and compatible with the standard press and compression fitting families used in floor heating work.
The best fitting is the one you never had to install.
Key Features
- ✦ 656 ft (200 m) single coil, enough to run a full floor loop without a mid-run joint
- ✦ PEX inner and outer layers bonded to an aluminium core for shape retention and oxygen barrier
- ✦ Temperature range of minus 40 to 95 degrees Celsius, 70 degrees working temperature
- ✦ 5/8 inch (16 mm) outside diameter with a 2 mm wall and a smooth internal bore
- ✦ Bends by hand and stays in the bend, which removes elbows from the layout
- ✦ CE certified and compatible with standard press and compression fittings
- ✦ Ships with a pipe cutter, a rounding tool and 20 clamps
- ✦ Suits radiant floor heating, domestic hot and cold water lines, and heat pump circuits

Where It Belongs
A 200 metre coil is the right quantity for anyone laying a floor heating loop or replacing a long run of buried pipe, which is why hydronic installers keep a coil racked on the van. It suits a renovation where the floor is already open and the pipe can be laid as one continuous run, a workshop or garage where a hot water line has to travel the length of the building, and a heat pump installation where the outdoor unit sits far from the manifold. It is also the material of choice for retrofit work in older properties, because a bendable coil threads through joist spaces that rigid pipe cannot follow.

Frequently Asked Questions
Q: How long is the coil and what does it cover?
656 feet, or 200 metres, in one continuous length. That is enough for a substantial floor heating loop or a very long domestic supply run, so a single coil often covers the whole job.
Q: What temperature can it handle?
Minus 40 to 95 degrees Celsius, with a stated working temperature of 70 degrees. That range covers hot water distribution, radiant floor loops and the colder side of a heat pump circuit.
Q: Why use composite pipe instead of plain PEX?
The aluminium core is what keeps the pipe in the shape you bend it into, so runs follow a wall and stay put without clips every 300 mm. The metal layer also acts as an oxygen barrier, which protects the metal components in a heating circuit.
Q: What fittings work with it?
Standard press and compression fittings for 16 mm composite pipe. The coil ships with a pipe cutter, a rounding tool and 20 clamps, so you can start the same day.
Q: Can it be used for drinking water?
The manufacturer lists domestic hot and cold water lines among the applications and the pipe is CE certified. Local plumbing code still decides what is acceptable on a potable supply, so confirm with your installer before closing a wall.
Q: How do I stop the coil from kinking?
Use the rounding tool that ships in the box to restore the bore after every cut, and keep the bend radius generous. Composite pipe kinks less than plain PEX because the aluminium core resists collapse.
Q: Is the coil heavy to handle?
It arrives as a single coiled bundle and is manageable by one person with a reel or a second pair of hands. Unroll it along the run rather than pulling it off the side, which is what causes twists.
