Hygroseal™ de-aeration valve for Underfloor Heating Manifolds

he Aladdin automatic de-aeration valve range now includes a model for underfloor heating system manifolds, the UFH Autovent. ***The UFH Autovent utilises the same patented Hygroseal™ technology that has operated the Aladdin Autovent radiator de-aeration valves since 2006***. The UFH Autovent differs from the rest of the range in that its different combination of internal materials allows it to operate at lower temperatures than the radiator-bleeding versions. Aladdin Autovents continue to provide a cost-effective solution to automatic de-aeration due to their long, leak-free life: the UFH Autovent has a 3 year operating guarantee, and will not leak at the eventual end of its operating life.
