A guide to which pipe to use for water underfloor heating
The right pipes are the
heart of any water underfloor heating system, so we’re very particular about
the ones we supply. At Snug, we believe PEX and AL-PEX pipes bring a whole range of real advantages,
Why use PEX & AL-PEX rather than PERT
& AL-PERT pipes?
- They make life easier for installers because they’re lightweight and more flexible than PERT & AL-PERT.
- PEX & AL-PEX pipes can withstand up to 95ºC, while PERT can only withstand 60ºC. Water underfloor systems reach 65ºC if their mixing valves are turned right up, so choosing PEX or AL-PEX gives you peace of mind that your system will keep going strong, even at capacity.
- Unlike PERT & Al-PERT, PEX & AL-PEX doesn’t need reaming if you use a pipe cutter, saving valuable time.
But what’s the
difference between PEX & AL-PEX?
The key difference between PEX & AL-PEX pipe is
that AL-PEX is WRAS approved, meaning that you can use the same pipe
through-out your home or project, including pipe for potable (drinking) water,
leading to a more efficient project, as any excess piping can be used elsewhere
in a project.
understand that each project is unique and requires components relative to your
needs. Whilst we recommend using PEX & AL-PEX over PERT & AL-PERT,
there are different benefits of each which may be advantageous to your job:
