Passive Shower EcoTray - A shower tray with a heat recovery device that reduces shower water heating bills

The solution recovers heat from the used shower water, preventing it from being lost down the drain. That energy is reused to warm the incoming cold-water mains. It halves the amount of energy used by your shower without diminishing the experience. It is physically a regular shower tray that reduces energy consumption, carbon emissions, and saves money compared to traditional showers. The product is maintenance-free, with no moving or electrical connections.
