The world’s most environmentally friendly toilet cistern

Save water. Save money.

See how it works

Eco Cistem uses the condensation from air conditioning units to flush toilets.

Until now, this free, sustainable source of water has been drained to waste.

See how it works

The Eco Cistem works in exactly the same way as a traditional cistern

With the exception that it has an extra filling connection to allow a separate water source to be introduced (from the air conditioning unit).

See how it works

Eco Cistem holds 18 litres of water

Which is three times more than a conventional cistern thanks to its dual-chamber design.

Both chambers are filled with condensate, when the air conditioning system is in use.

When flushed, the lower chamber is replenished by the upper chamber, to ensure a quick refill.

How does it work?

When the toilet is flushed, the lower chamber is emptied and then refilled with condensate from the upper chamber.

Find out what you could save

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.

Conversely, if the toilet is not used for a while, surplus condensate is simply drained away.

Find out what you could save

Eco Cistem can be used in any concealed toilet installation.

This includes both new build applications or as a retrofit to existing toilets.
