External Installations

If Hep2O® is installed in an external application then the system will require protection from frost. Although Hep2O® has lower thermal diffusivity than copper, insulation requirements are the same as those of copper and should be in accordance with BS 5422, BS 6700, Water Byelaws and Building Regulations Approved Document L.

Hep2O® pipe is less likely to burst should the water in the pipe freeze, however should Hep2O® be connected to a metal pipe, a metal tap or a close configuration of fittings (incorporating metal support sleeves) then the likelihood of a failure due to the expansion of frozen water will be increased.

If Hep2O® is used externally it should be protected from the ultra-violet radiation in sunlight. If insulation has been installed to avoid freezing this is sufficient. However, where insulation is not used, painting or covering is recommended.
