Paul Crossley, former managing director of JT,  now leads the launch of eco-cistem, which is claimed to be the world’s most efficient toilet cistern.

The toilet cistern uses grey condensate water for flushing and is specifically designed to work with air conditioning units that produce varying amounts of condensate water, which typically goes directly into the waste pipe.

In an eco-cistem installation, this grey water is redirected to the toilet cistern and used to flush the toilet(s).

According to the company, a 1.75kw aircon unit, which it states is one of the smallest on the market, can produce over 1 litre of condensate per hour.

The eco-cistem unit features a patented 18-litre, twin-chamber cistern that can store up to 12 litres of ‘free’ condensate grey water above a standard 6-litre chamber dedicated to flushing the toilet.

The unit prioritises using grey water for flushing and only pulls in fresh water when no grey water is available.

Designed and manufactured in the UK and suitable for wall-hung or frame-mounted WCs, it can be used in hotels, apartments and office blocks.

Ecocistern has been created as a concealed installation, can fit in standard service voids, and has adjustable flush volumes between 3.5 and 6 litres to suit worldwide regions.

It has undergone testing and received WRAS approval, ensuring compliance with UK Water Supply Regulations.

Additionally, it has passed the AB Air Gap test conducted by KIWA, achieving Category 5 compliance.

The cistern is also eligible for BREEAM points under WAT 01 for water consumption and can earn up to six points in LEED’s water efficiency category.

Following development work and case studies, the product is now in stock and ready for distribution.

The eco-cistem product was developed and is now the trading name of The Green Futures Initiative Ltd, founded by the directors of G&H, a Mechanical, Electrical, and Public Health (MEP) building services company based in Yorkshire.
