Cerian Shower EcoTray


WHAT IS IT? A Shower tray with a heat recovery device that reduces shower water heating bills by up to 40%, improves energy efficiency, and cuts carbon footprints. It is a passive energy-saving element with a static heat recovery unit, without moving elements, it does not need maintenance and it has the same useful life as the building. Quite simply, it is a system or technology that uses the heat from the waste hot water in the shower to increase the temperature of the incoming cold water. HOW DOES IT WORK? When we take a shower we are throwing away the energy we have used to heat the water down the drain. During the process, the hot water used flows directly down the sewerage system and much energy is wasted. It doesn't make sense to waste all that energy and reheat cold water to use it again for just a few seconds. This is the challenge that Cerian steam tried to overcome with their technology. It is possible to recover and reuse that energy that we have already paid for to heat the water again without having to consume more energy and money. Cerian shower EcoTray is a wastewater heat recovery (WWHR) system that can effectively recapture and reuse instantly a high percentage of the energy lost into the drain, reducing energy consumption in a cost-effective manner. It is a simple system, with no moving parts, no storage, no control system, and requires no electricity to operate. A specifically engineered heat exchanger transfers heat energy from the waste hot shower water to the incoming freshwater supply, warming it from around 10 up to 30°C. When the cold water arrives at the mixing valve, it is much warmer, and therefore substantially less hot water is required from the water heater or solar array. WHERE TO INSTALL? It can be installed in newly built homes and in bathroom renovations and bathtub-shower changes. Due to its flat design, it is installed as a conventional shower tray, without making holes in the floor, facilitating the use of the shower for people with reduced mobility.
