Save energy and invest effectively with ECOTHERM solutions - Sheraton Hotel & Towers Hong Kong project

Effectively saving energy and investment costs for buildings is an urgent global issue. It requires buildings to consume less energy, reduce CO2 greenhouse gas emissions, and be safer. A hotel's central hot water and steam systems are critically important, and achieving efficient energy reduction is absolutely necessary. With a long history dating back to 1880 and decades of research, development, and manufacturing of specialized hot water tank solutions, ECOTHERM has made a name for itself in the international market. This is thanks to its solutions for upgrading and renovating hot water systems to improve efficiency and save energy and investment costs. These solutions are not only for hotels, but also for hospitals, stadiums, schools, residential buildings, offices, and industrial applications.

The upgrade of the hot water and steam system for the Sheraton Hong Kong Hotel resulted in a 25% energy saving

Outstanding Advantages of ECOTHERM's Hot Water and Steam Solutions

The brand impresses customers with its "Individual Heat Transfer Solutions" for upgrading and renovating hotel hot water and steam systems. All components of the ECOTHERM Industrial Hot Water Heating Tanks are made of high-quality stainless steel. Each system can be custom-designed to meet the needs of each specific customer and project.

ECOTHERM's engineers use proprietary software to design and optimize the hot water system upgrade process for hotels. This brings maximum efficiency with minimal floor space requirements, helping to save energy and maintenance costs.

ECOTHERM's turnkey hot water systems meet the highest quality standards with high efficiency. Therefore, the initial investment cost is higher than other systems. However, it leads to significant annual savings on primary energy (oil, gas, or electricity), reduced heat loss from the storage tanks, lower maintenance costs, and a significantly longer lifespan compared to other conventional systems.

In addition, ECOTHERM's high-capacity hot water heating tank solution helps save up to 95% of floor space. This is possible thanks to ECOTHERM's compact, high-efficiency shell-and-tube heat exchangers with patented free-floating agitators, which mean that hot water is produced mainly on demand. Therefore, only a very small storage capacity is needed while still ensuring maximum hygiene.

This saves space in the boiler room and, as a result, also saves costs for upgrading and renovating the hotel's hot water system.

Furthermore, ECOTHERM's commercial hot water heating tank solutions can also save on equipment operating costs due to less heating efficiency loss from blockages and low heat loss. This is exactly what makes it a superior solution for upgrading and renovating a hotel's hot water system.

For example: An ECOTHERM hot water heating system with a 2,000-liter tank and two heat exchangers, each with a capacity of 1,500 kW, can supply up to 25,000 liters of perfectly hygienic hot water per hour at 60°C with 100% redundancy—enough for a 500-room hotel.

Upgrading the Hot Water and Steam Systems at the Sheraton Hotel & Towers Hong Kong with an ECOTHERM Solution

In 2008, Ecotherm upgraded the hot water and steam systems at the Sheraton Hotel & Towers Hong Kong by replacing the entire old hot water and steam system while the hotel was still operating as normal. This was done through a 1.2-meter-wide door without interrupting the supply of hot water and steam to guest rooms, the kitchen, and the laundry room.

ECOTHERM Turnkey Steam & Hot Water System

• 4x Electric Hot Water Systems (800 kW & 2000 l),
• 2x Electric Steam Boilers (each 1,800 kg/h 10 bar),
• 4x Heat Pumps (350 kW)
• Savings

ECOTHERM replaced the entire steam & hot water system during full operation of the hotel through a door of only 1.2 meters, without interrupting hot water & steam supply to guest rooms, kitchen and laundry.

• Reduction of hot water storage volume from total 150.000 litres to only 8.000 litres
• approx. 200 m2 space saving
• approx. 25% fuel savings

Conclusion

Thanks to the customized design of each system and the shell-and-tube heat exchangers with patented free-floating agitators, the system requires minimal floor space. This reduces the initial investment cost for upgrading a hotel's hot water and steam system. The use of high-quality stainless steel, combined with an automatic anti-scaling cycle, provides perfectly hygienic hot water for the hotel's hot water and steam systems. The experience from thousands of installations ensures stable operation with low maintenance costs. Because the ECOTHERM hot water system uses minimal tank volume, it saves water as well as primary energy for the hotel's hot water system. The renovation of the hotel's hot water system using the company's proprietary fire-resistant insulation material has helped reduce heat loss by up to 30%. With thousands of installations in Europe, the Middle East, Asia, North Africa, and Central America, ECOTHERM has become a leader in technology and innovation for individual solar, hot water, and steam solutions on the market.
