What makes Haase Tank’s heat storage system so special?<\/h3>\n\n\n\n

+<\/strong> on-site installation of the hot water tanks means you are not restricted by the installation dimensions
+<\/strong> the hot water tanks can operate at temperatures up to 95\u00b0 C
+<\/strong> high flexibility: 1 m to 4,5 m diameter, up to 3,60 m heigt
+<\/strong> the technical equipment required for loading and unloading the thermal storage tank can be selected with complete flexibility to suit the specific project
+<\/strong> the use of external heat exchangers means there is no risk of legionella
+<\/strong> Haase Tank has been manufacturing GRP hot water tanks for over 25 years
+<\/strong> the use of GRP results in 200 times less heat loss than with steel storage tanks<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Hot water tanks can be especially used where very large amounts of excess heat are produced, which can be used later. For example:<\/p>\n\n\n\n

Other possible uses: butchers, hotels, housing estates, dairies, food manufacturers, industrial companies and much more, where waste heat is generated and can be used later. Here you’ll find more successful projects.<\/a><\/p>\n\n\n\n

EQUIPMENT VARIANTS OF THE HOT WATER TANK<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

All equipment variants listed below can be combined with each other.
This is useful, for example, if heat is constantly introduced into the storage system via a stratified charging unit and discharged again quickly via a side flange.<\/p>\n\n\n\n

HOT WATER TANK WITH FLANGE CONNECTIONS (BUFFER STORAGE)<\/h3>\n\n\n\n
\n

\"The<\/a><\/figure><\/div>\n\n\n

+<\/strong> the tank is loaded and unloaded via the upper and lower flanges
+<\/strong> the individual temperature sensors allow the various temperature layers to be measured digitally
+<\/strong> the number and size of the flanges can be selected as required \u2013 this enables use as a non-pressurised circuit and the loading or unloading of large amounts of energy within a short time
+<\/strong> the GRP material allows additional flanges to be fitted at a later date
+<\/strong> As the heat storage tank operates without pressure, an internal or external heat exchanger is required to isolate the system
+<\/strong> GRP is resistant to ageing, rust-free and allows for a high degree of flexibility regarding the tank\u2019s dimensions<\/p>\n<\/div>\n<\/div>\n\n\n\n

HOT WATER TANK WITH CORRUGATED STAINLESS STEEL PIPE HEAT EXCHANGERS<\/h3>\n\n\n\n
\n
\n
\"The<\/a><\/figure><\/div>\n\n\n

+<\/strong> heat is absorbed and released exclusively via internal heat exchangers made of corrugated stainless steel pipes
+<\/strong> consequently, the water used as the storage medium inside the tank is completely separated from the individual circuits of the heat generators
+<\/strong> this also means there is never any risk of Legionella, as no large volume of hot water is stored in the tank
+<\/strong> during operation, the hot-water exchanger utilises all the energy from the entire height of the tank, as the water begins to heat up at the bottom before the water at the top reaches the final hot-water temperature
+<\/strong> this utilisation of the entire tank volume has the advantage that, for example, the solar system can always operate within its optimum operating range
+<\/strong> generally speaking, all heat exchangers are technically designed to meet the requirements of the intended heat generator for efficient operation
+<\/strong> this design also allows for the direct and simultaneous storage and release of thermal energy from multiple sources
+<\/strong> the geometry of the corrugated tube ensures turbulent water flow, thereby minimising limescale deposits
+<\/strong> no expansion tank is required for the storage volume<\/p>\n<\/div>\n<\/div>\n\n\n\n

HOT WATER TANK WITH LAYER LOADING UNIT<\/h3>\n\n\n\n
\n
\n
\"By<\/a><\/figure><\/div><\/div>\n<\/div>\n\n\n\n

+<\/strong> the stratified loading unit enables water to be stored in the appropriate temperature stratum according to its temperature and density
+<\/strong> during loading, the cold water is drawn off via the lower suction plate and fed to the heat generator
+<\/strong> during unloading, the hot water is drawn off via the upper suction plate and fed to the heat consumer
+<\/strong> this efficient stratification of the different temperatures enables the entire system to operate optimally, which means, for example, that the operating times of heat generators can be extended
+<\/strong> furthermore, heat generators and consumers with high and low output can be combined very effectively with different temperature levels
+<\/strong> Mixing between different temperature layers is kept to an absolute minimum
+<\/strong> as the heat storage tank operates without pressure, an external heat exchanger is required to separate the systems<\/p>\n\n\n\n
