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.
