The First Energy Saving Shower Tray with Graphene

2026-07-22

The smart-home is a growing market due to customers’ demand. Furthermore, new regulations from the EC coming into force in 2018 and their transposition into national laws, require the use of energy efficient solutions in hot water supply in buildings, which makes this a key market. The shower-tray market alone, estimated in 29M of trays, gives a European market of about €600M in 2018, with a CAGR of 10%. The SME Cerian Shower developed and patented a built-in system for residual heat recovery in shower trays. It consists in a shower tray with a highly efficient heat-exchanger. This facilitates “doit- yourself” installation for end-users and gives agility and lower costs to both end-users and construction companies. With Cerian Shower system, up to 40% of the energy used to warm up water for a shower is recovered. With the collaboration of Graphenano, a SME producing graphene, we will also include graphene in our solution, which we estimate will increase by another 40% the efficiency in energy use. Following the first prototypes developed by Cerian Shower, the company wants to pursue certification product certification in The Netherlands, testing in real settings, and developing further agreements with customers. This will be done during this 5-month SMEInst-1 project. Progressing further in up-scale production via SMEInst-2, Cerian Shower will reach €56M revenues in 2023, and Graphenano will reach €3M revenues in the same year. About 200 new jobs will be generated as a result of full commercialisation of Passive Shower EcoTray in Europe alone.
