Worcester Bosch Group Logo

Martyn Bridges, Technical Director
(WB technical website)

Vaillant Logo

Glow Worm Logo
The hotun addresses the issue of removing outflow from a sealed system pressure relief valve into an internal waste or soil pipe, preventing foul odours back into the building when connected to discharge pipes specified as suitable for the temperatures and pressures involved in the system
Martin Butcher, Technologies Specification Manager

Ariston logo
hotun provides a great option if you are not able to terminate your PRV discharge pipe to a safe location outside… The hotun has been used many times with our Small Electric Water Heater products including the Europrisma and most recently our Andris Lux models

Ideal Logo

The hotun hiflo is acceptable for use with ideal condensing boilers, it offers a useful solution to the issue of combining a sealed system boiler pressure relief discharge and condensate pipe into a single termination point to a buildings waste water system. Please note that the waste pipes need to be of a standard to accept the potential pressures and or temperatures involved with a sealed system under discharge scenarios
