Energy-saving measures are standard features of today’s buildings and are usually applied to the whole structure. Nevertheless, there had always been a missing piece to the puzzle that no one had been able to solve when it came to ventilation for the stack – that is, until the Geberit energy retaining valve ERV came along. When a toilet is flushed, for instance, this kind of opening prevents negative pressure from forming and traps from being blown empty. In the past, the open stack would always result in constant heat losses via the drainage system.
Now, however, the innovative Geberit energy retaining valve ERV makes this problem a thing of the past by:
- only opening when required thanks to its patented diaphragm system
- always ensuring pressure compensation when required
- preventing unnecessary heat losses and thereby increasing the energy efficiency of the building
