What happens when the expansion vessel fails? Watch our demo and find out how useful the hotun detect alarm unit is.

If a boiler loses all of its pressure, it will lockout. That creates a problem as the boiler will stop so the homeowner will call their plumber putting you under pressure to come out and fix it there and then.

With the hotun detect alarm fitted onto the hotun dry trap tundish, when the water passes out of the tundish, the alarm sounds. The homeowner lets you know the alarm is sounding but you’ll have a number of days to fix the boiler as an appointment, rather than emergency call out. Reducing the pressure on you!
