Zypho, a young and highly innovative Portuguese company leading the way in drain water heat recovery technology, was one of the most exciting acquisitions we made in 2023.

We’re investing in external growth through M&A transactions with a focus on boosting our innovation capabilities so that we can bring great solutions to our customers at scale and at a much faster pace.

Zypho meets those criteria very well and we’re delighted to welcome them to the Aliaxis family, cementing a collaboration that began in 2020.

Back then, we began working with Zypho to help them bring their innovative and highly sustainable heat recovery solution to market in Portugal, Spain and France.

The system captures the outgoing hot wastewater from a shower and uses it to heat the incoming cold water, in the process recycling up to 75% of the energy needed to produce hot water.

It’s also a passive system using gravity and so is free from the need for additional energy. Thanks to its double layer protection, water running through the system is also protected from contamination.

It’s a solution that not only increases energy efficiency in homes, but also cuts carbon emissions, at a time when people are looking both to reduce their carbon footprint and soaring energy bills.

The acquisition means we can help develop their great ideas more quickly drawing on the skills of our own innovators for the benefit of customers across our markets and we’re doing just that.

Together we’ve created new and more innovative products such as the horizontal heat recovery unit that we brought to the French market in late 2022.

We also launched a new product in 2023 – Zypho Slim50, a compact drain water heat recovery system designed for use in smaller properties and perfectly suited for the renovation market.

We achieved a big customer win in 2023 when the Accor Hotel Group in France selected the system for use in its Pullman Paris Bercy Hotel, with trials underway in the first rooms and plans to fit the system in all of the hotel’s 392 rooms in the coming year.

Now we have the chance to use our global scale to take Zypho solutions to a much wider market.
