Whether the boiler is fired on oil, gas or solid fuel, it may be expected that it will operate automatically. When boiler plant is not run continuously initial start-up may be manual, time clock or through an energy-management system. Manual attendance may be limited to maintenance functions dictated by the type and size of plant. Automatic controls will cover three areas ... 

Energy-management systems will form an important part of a multi-boiler installation, whether on steam or hot water. Boiler(s) for base load will be selected and further boilers brought on- or taken off-line as required. The important feature of these systems is that the selection of boilers coming either on- or off-line will be ahead of the load and programed to anticipate rising or falling demands. 

Energy management systems can vary in cost from low to high ( 100,000- 200,000) for the system itself. In addition, energy controls may have to be provided either to replace existing controls which are not compatible or which are not operating correctly or have never been provided in the past. 

With such systems, it is possible to obtain individual room space heating and humidity control without the need to dispatch an engineer to check every room in the building. Manpower costs can be reduced, with the staff being required for checking and maintenance purposes only. The cost of an energy management system can be recovered in a relatively short period of time (of the order of 2-3 years). 

The cost of an energy management system at one site in the north of England was of the order of 1,000,000 and the payback period was just over 2 years. In view of the high cost of such systems, it may be possible to obtain a system on a loan basis, the system being rented from the installer or by lease purchase. All options should be considered before entering into a contract. 

It is possible to undertake theoretical calculations to ascertain the amount of energy required for the operation and to compare this with the actual consumption. To do this requires the knowledge of a large number of parameters but it can be undertaken, especially if an energy management system is installed. 

The aim is to reduce the consumption of energy and water to the bare minimum. Computerized systems are used extensively. Such systems have different names Building Automation System (BAS), Energy Management System (EMS).

Because of both the heat dissipation and hydraulic concerns, we use a relatively small FEHE 1000 ft2 compared to the Stanford Research Report s listed area of 3100 ft2. So the energy management system...
