Speichertanks

Speichertanks are containers designed to store liquids or semi-liquid substances for processing, distribution, or energy management. They are used in residential, commercial, and industrial settings to provide a reliable supply, maintain process conditions, and support energy storage. Depending on the application, Speichertanks can be vertical or horizontal, cylindrical or rectangular, and vary in size from a few hundred liters to many thousands of liters.

Common applications include domestic hot water storage tanks, which hold heated water for daily use; solar thermal systems, where thermal storage buffers intermittent solar input; and industrial settings, where tanks store chemicals, fuels, process streams, or water. In district heating and other energy systems, large-scale storage tanks help balance supply and demand by storing heat for later use.

Materials and construction are chosen according to the stored substance. Potable water tanks often use stainless steel or carbon steel with protective linings; chemical or aggressive fluids require corrosion-resistant materials or inner linings; large underground or groundwater-exposed tanks may use concrete. Some tanks employ insulation to minimize heat loss, while others are made from reinforced plastics or coated metals. Tanks may be pressurized or open to atmosphere, and some include heating coils, heat exchangers, or mixing devices to control temperature and homogeneity.

Key features commonly found on Speichertanks include inlet and outlet connections, level and temperature sensors, venting and pressure relief devices, manholes or access hatches, and insulation jackets. Maintenance involves regular inspection for leaks and corrosion, cleaning for sanitary or process reasons, verification of insulation integrity, and testing safety devices. Regulations and standards vary by country and application, but many tanks must meet regional codes for pressure, containment, ventilation, and environmental protection.

Volumes typically range from a few hundred liters for domestic systems to several thousand liters for commercial installations, and up to tens of thousands of liters or more for industrial use.
