The Hotun hiflo dry trap tundish can be used for large unvented hot water heaters (more than 15 litres capacity) and boilers (with a Hotun shield). By connecting a hotun hiflo dry trap tundish it allows a safe and visible discharge from the boiler temperature/pressure relief valve to be connected to a waste/soil without allowing any foul odours back into the building, thereby allowing a compliant connection.

Worcester Bosch, Vaillant, Ideal Heating, Ariston and KD Navien all allow the use of hotun hiflo with shield to safely discharge the boilers PRV and, when applicable, to combine the condense into the same single pipe discharge below the hotun for a compliant connection.
