Hot water storage tanks
Hot water storage tanks store heated drinking water and make it available on demand for the bathroom, kitchen, and house installation. They are suitable for heating systems where hot water needs to be reliably stored and made available via appropriate storage technology.
In the GEMA Shop you will find hot water storage tanks for various system concepts, storage sizes, and areas of application – suitable for new construction, renovation, heating modernization, and combination with various heat generators.
Notes
Use the filters to narrow down the selection by relevant characteristics 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 hot water storage tank
Hot water storage tanks are storage solutions for the central provision of domestic hot water. They are used in heating systems to store heated water and provide it on demand at draw-off points such as showers, bathtubs, washbasins, or kitchens. Depending on the design, hot water storage tanks can be combined with boilers, heat pumps, solar thermal systems, or other heat generators.
The right storage solution depends on the hot water demand, the number of users, the heat generator, the desired integration, and the available space. It is also important whether the tank is intended for direct drinking water use, how heat transfer occurs, and which connections, heat exchangers, or system functions are required.
Advantages of hot water storage tanks
- Central hot water provision: Hot water can be stored for multiple draw-off points in the building.
- Flexible system integration: Depending on the design, combinations with boilers, heat pumps, or solar thermal systems are possible.
- Plannable storage solution: Storage volume, material, insulation, and heat exchanger can be selected to match the system concept.
- Suitable for new construction and renovation: Hot water storage tanks can be integrated into new and existing heating systems.
Areas of application and target groups
Hot water storage tanks are suitable for homeowners, self-builders, buyers with plumbing and heating expertise, and technically interested end customers who want to plan, replace, or modernize a central hot water solution. Typical areas of application include single-family homes, multi-family homes, renovations, new constructions, and systems where hot water is to be provided via a central storage tank.
Important selection criteria for hot water storage tanks
When selecting, particular attention should be paid to storage volume, storage type, drinking water suitability, material, insulation, number of heat exchangers, maximum operating pressure, maximum temperature, installation height, and connection options. For further system planning, storage technology, buffer tanks, heat pump storage tanks or suitable Heating accessories & system technology be relevant.
Note on professional sizing
The selection of a hot water storage tank must match the actual hot water demand, the heat generator, the system hydraulics, the drinking water installation, and the available installation space. Information on volume, application area, or system compatibility is for orientation purposes and does not replace professional planning.
Frequently asked questions about hot water storage tanks
What is a hot water storage tank?
A hot water storage tank stores heated drinking water and makes it available on demand at the draw-off points in the building, for example in the bathroom, kitchen, or shower.
What is the difference between a hot water storage tank and a buffer tank?
A hot water storage tank stores domestic hot water. A buffer tank stores heating water for the heating system. Both types of tanks perform different tasks in the system.
Which hot water storage tank fits my heating system?
That depends on the heat generator, the hot water demand, the system hydraulics, and the connection options. It is important that the tank, heating unit, and control system are technically compatible.
Can a hot water storage tank be combined with a heat pump?
Yes, depending on the design, a hot water storage tank can be combined with a heat pump. In this case, the tank must be suitable for the temperature level and operating mode of the heat pump.
Can a hot water storage tank be used with solar thermal systems?
Yes, a suitably sized storage tank with the appropriate integration is required for this. Depending on the system design, heat exchangers and controls can be important for solar hot water preparation.
What size should a hot water storage tank be?
The appropriate storage tank size depends on the number of users, draw-off behavior, hot water demand, heat generator, and system design. A blanket selection based only on living space is not sufficient.
Does a hot water storage tank replace system planning?
No. A hot water storage tank is an important system component, but it does not replace proper planning. Storage tank size, connections, safety equipment, and drinking water hygiene must be appropriately designed.
