On average, approx. 6000 kWh of electricity and 29,000 kWh of heat are consumed per bed per year, corresponding to a heat demand of 6,960,000 kWh p.a. and an electricity demand of 1,440,000 kWh p.a. This high energy demand also results in high energy costs.

Application: market environment.
Modernization in the healthcare sector.
- more than 80 % of existing systems are operated inefficiently
- energy centers are rarely a management focus in hospitals
- 2100 hospitals in Germany (total expenditure € 60 billion, of which energy accounts for € 1.5 billion)

Application: object.
Modernization in the healthcare sector.
A hospital.
In order to meet the very high energy demand of the building in an economical and environmentally friendly manner, the old system should be modernized using advanced systems technology.

Application: requirements.
Modernization in the healthcare sector.
Requirements:
- extremely large output range for the production of heat and power
- remote monitoring or BMS connection
- operating cost savings
It is common for a hospital to have around 240 beds.
Use of steam boiler systems.
As an alternative, gas steam boiler systems can be used to provide energy in hospitals. The steam that is generated is used for kitchens and the central sterilization department, for humidification of the air conditioning system and for the laundry.

- high pressure stability and steam quality with intuitive PLC-based boiler control
- suitable for all burner systems
System: extension stage 2.
UL-S universal steam boiler.
System benefit:
The UL-S steam boiler is delivered as standard with integral economizer (additional flue gas heat exchangers). This ensures a high level of energy utilization. The result is a fuel saving of up to 7 %. It also means reduced demand for resources and therefore lower emissions. A complete steam boiler system includes not just a steam boiler but also a wide range of system components which help to achieve further energy savings and lower costs and emissions.
Reference system at Winsen hospital.
The system for steam provision, which was installed 38 years ago, has been successfully modernized. The hospital’s technical directors, Dipl.-Ing. Torsten Riemer and Thorsten Holz, are very pleased: “The modernization instantly achieved natural gas savings of around 15 %. Reduced CO2 emissions mean we are also making an important contribution towards climate protection.”
