Domestic hot sanitary water Delivering better indoor experience An efficient hot water production system reduces costs and water waste while delivering superior comfort to guests, ensuring better experience and eliminating safety risks There are various challenges hotels meet in their daily operations when it comes to domestic hot sanitary water, namely: demand for high performance, guest comfort, superior hygiene and a resource-efficient operation. It’s no wonder then, that domestic hot sanitary water is the second-largest expense for hotels after HVAC. Usually, traditional systems will operate at constant flow resulting in huge energy consumption and significant waste of water. By using a smarter Danfoss solution based on the thermal balance of the system which maintains a constant temperature in the plant itself and limits the flow rate in the recirculation pipes to the minimum required level, hotels can ensure the lowest possible consumption while maintaining the best plant performance. Danfoss supports your hotel with delivering best service to your guests at lowest costs. We offer a complete domestic hot water solution that includes water heaters, storage and charge systems, the hot water valves and temperature controllers. When used together, these meet key challenges including high performance, comfort, hygiene and resource-efficient operation.
