Hygienic storage tanks
Hygienic storage tanks combine heat storage with hygienic domestic hot water heating on the flow-through principle. They are suitable for heating systems where heating heat is to be stored and hot domestic water is to be provided on demand.
In the GEMA Shop you will find hygienic storage tanks for various system concepts, storage sizes and heat generators – suitable for wood heating, heat pumps, solar thermal systems and combined heating systems.
Notes
Use the filters to narrow down the selection by relevant properties such as manufacturer, product type, area of application, technical features, or availability. The information is provided for orientation purposes and does not replace a check of the technical suitability, compatibility, or proper use of the product.
Choosing the right hygienic storage tank
Hygienic storage tanks are storage solutions for heating systems in which heating water is stored and drinking water is only heated on demand. Unlike conventional hot water tanks, the drinking water is not permanently stored in the tank, but is heated on demand via an integrated heat exchanger or a fresh water system, depending on the design. Hygienic storage tanks can therefore be a sensible solution when heat storage and hygienic hot water preparation are to be combined.
They are often used in systems with wood heating, pellet boilers, heat pumps, solar thermal systems, or combined heat generators. It is crucial that the tank type, tank volume, heat exchanger, temperature range, and hydraulic integration match the respective heating system.
Advantages of hygienic storage tanks
- Hygienic hot water preparation: Drinking water is heated on demand and not stored as a large volume of drinking water permanently.
- Combination of heating and hot water: The tank can make heat usable for both the heating system and drinking water preparation.
- Flexible system integration: Depending on the design, combinations with wood heating, heat pumps, or solar thermal systems are possible.
- Structured selection: Storage tanks can be compared by volume, heat exchangers, insulation, and system compatibility.
Areas of application and target groups
Hygienic storage tanks are suitable for homeowners, self-builders, buyers with plumbing/heating expertise, and technically interested end customers who are planning a modern storage solution for heating and hot water preparation. Typical areas of application are single-family homes, renovations, new builds, combined heating systems, and installations where hygienic drinking water preparation is to be combined with heat storage.
Important selection criteria for hygienic storage tanks
When selecting, special attention should be paid to storage volume, storage type, number of heat exchangers, hygiene function, drinking water suitability, insulation, maximum operating pressure, maximum temperature, and suitability for the respective heat generator. For further system planning, additional buffer tanks, heat pump storage tanks, solar storage tanks or suitable Heating accessories & system technology be relevant.
Note on professional sizing
The selection of a hygienic storage tank must match the building, the hot water demand, the heating load, the heat generator, and the system hydraulics. Information on volume, application area, or system compatibility is for orientation only and does not replace professional planning.
Frequently Asked Questions about Hygienic Storage Tanks
What is a hygienic storage tank?
A hygienic storage tank is a heat storage tank that stores heating water and heats drinking water as needed. The drinking water is generally not stored permanently as a large volume.
What is the difference between a hygienic storage tank and a hot water storage tank?
A classic hot water storage tank stores hot drinking water directly. A hygienic storage tank heats drinking water mostly on the flow-through principle via a heat exchanger or a fresh water system.
Which heating systems are suitable for hygienic storage tanks?
Depending on the design, hygienic storage tanks can be used with wood heating, pellet boilers, heat pumps, solar thermal systems, or combined heating systems.
Does a hygienic storage tank require a heat exchanger?
Many hygienic storage tanks work with an integrated heat exchanger or a fresh water solution. Which design is suitable depends on the system concept and the hot water demand.
What size should a hygienic storage tank be?
The appropriate storage tank size depends on hot water demand, heating system, heating load, user behavior, and hydraulic integration. A blanket selection based only on living space is not sufficient.
Can a hygienic storage tank be combined with solar thermal systems?
Yes, depending on the design, hygienic storage tanks can be integrated into solar thermal systems. Suitable heat exchangers, temperature ranges, and proper hydraulics are important.
Does a hygienic storage tank replace heating system planning?
No. A hygienic storage tank is an important system component, but it does not replace proper planning. Tank size, connections, safety equipment, and integration must match the overall system.
