The Challenge
There are around two billion air conditioners worldwide, and the International Energy Agency (IEA) estimates that this number will triple to 5.5 billion by 2050.
Each of these air conditioners produces water, the majority of which goes straight to waste.
Until now.
Air conditioning units produce vast amounts of water all of which goes straight to the waste pipe. Eco Cistem reroutes this water though the toilet cistern and reuses it to flush to toilets.
Eco Cistem is designed with two chambers. When flushed, the lower chamber is emptied and is then replenished with water stored in the upper chamber. This means the toilet can be flushed many times in quick session using water from the air conditioning unit.
Back up mains water supply
If there are multiple flushes in a short period of time, the cistern is filled in the conventional way. This ensures that a full toilet flush is available even when usage frequency is high.
Stores 18 litres of water
Our patented dual chamber design means the toilet can store 18 litres of condensate water before reverting to mains water.
No electricity required
No electricity is required to operate an Eco Cistem so only a plumber is required to install it. Instead gravity feeds the condensate water into the cistern.
Drains surplus water
If the toilet is not used for a while, surplus condensate is simply drained away.
Quick refill
The lower chamber is replenished with water stored in the upper chamber to ensure a quick refill.
Carbon benefit
The Eco Cistem reduces carbon footprint by conserving water that would ordinarily go to waste, lowering overall water demand.
