Hotel Grey Water System with Heat Recuperation
Our hotel/hostel utilizes a well designed grey water system with heat recuperation- the second such system in the world. Through this, heat may be harnessed from previously used water, allowing for a decrease in energy necessary for heating further incoming water. The system saves around 4,000 liters of water daily. In addition, heat recuperation is also used in our air, ventilation, and cooling processes.
As seen here, our basement houses a recycling and regenerative unit- AquaCycle- which was tested and installed by Pontos Company. This system filters grey water in three cycles. We use the water for flushing the toilets, watering the plants, and washing the floors. This technology serves for the heat recovery from the recycling of grey water.
The water heating process is carried out in three steps. After cold water turns from 5°C to 25°C, heat recuperation from cooling heats the water from 25°C to 35°C. Then, our rooftop solar panels help us to heat the water from 35°C to 60°C. If the solar panels collect much energy during midday which is not used, the system stores the hot water (90°C) in an accumulating pot, and it is used toward any event rush.
