Product Range & Key Solutions

The Hotun product includes:

• Hotun 100 & SF dry‑trap tundishes – designed to give both compliance at installation and visibility at diagnosis, allowing safe discharge from a (T)PRV to internal waste or soil pipe without foul‑odour backflow.
• Hotun hiflo range – larger‑flow variants for bigger unvented cylinders or system volumes, rated at higher flow rates and capable of higher performance.
• Hotun detect – an in‑tundish alarm unit providing audible and visual alert if water starts to discharge via the tundish, thus helping catch faults early, save water and energy.
• Accessories / shields – includes items such as the hotun protect ventilated shield and hotun shield to add safety from scalding discharge water while maintaining compliance.
