Security of supply
The fundamental objective of security of supply is to ensure the continuous, reliable and economical provision of heat in order to meet consumer requirements.
The issue of necessary supply reliability always arises during the design stage in the context of process heat and heating energy supplies. It should always be clear that 100 % security of supply for all hours of the year cannot be achieved, or can only be achieved at a very high cost.
From a technical perspective, the following two scenarios are particularly relevant for security of supply:
- Failure of a heat generator
- Non-availability of a fuel or energy source
In some applications (e.g. district heating grids, local heating networks, hospitals or industrial processes) where interruptions in supply may cause considerable damage, the demand for security of supply is greater than in other industrial processes, where failures in the heat supply can sometimes be tolerated.
This is particularly relevant for heating systems, as the proportion of time during which maximum output is required is very low. This makes it unlikely that failure and maximum power requirement will occur simultaneously. In return, the costs for investment, maintenance and on-call services are lower.
Security of supply can also be increased without great effort through emergency management and risk impact assessment. One simple measure to achieve this would be, for example, to install emergency power supply options for mobile heat generators.
Various measures are necessary to ensure reliable operational management and avoid unexpected failures. An essential component is the availability of spare parts on site. For quick repairs and to minimise downtime, important spare parts, especially for safety-related components such as pumps, valves and seals, should be kept in stock at all times. Regular checks of spare parts inventory ensure that these parts can be replaced quickly without causing prolonged downtime. This ensures that the system remains ready for operation at all times.
To further safeguard supply, a service with 24/7 availability is also crucial. Service is available round-the-clock service and enables us to respond quickly in the event of a fault or failure, and to initiate the necessary repairs or maintenance measures immediately. This rapid access to experts prevents prolonged downtimes and ensures that the system can continue to operate efficiently, even in emergencies. Maintenance and inspection contracts covering this service should therefore be an integral part of the planning and operating concept.
Furthermore, risk management analysis is an important tool for ensuring long-term supply security. Preventive measures can be developed through a detailed analysis of potential risks, such as technical failures or unforeseen events. This includes regular maintenance intervals, staff training and the implementation of early warning systems to enable a rapid response to potential faults. Continuous review and adjustment of the risk analysis ensures that the system is always optimally prepared for new challenges and changing operating conditions.
Overall, the combination of redundant systems, spare parts in stock, reliable 24/7 service and a thorough risk analysis is the key to high supply security in hot water boiler systems. These measures not only help to reduce downtimes, but also increase the efficiency and reliability of the entire system, ensuring a continuous and secure heat supply.
