Solar storage tanks
Solar storage tanks store heat from solar thermal systems and provide it on demand for domestic hot water preparation or heating support. They are suitable for customers who want to integrate solar energy sensibly into their heating system.
In the GEMA Shop you will find solar storage tanks for various system concepts, storage sizes, and areas of application – suitable for solar thermal systems, heating modernization, renovation, and combined heat generators.
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 solar storage tank
Solar storage tanks are specifically designed for integration into solar thermal systems. They absorb heat from solar collectors and make it available for domestic hot water preparation, heating support, or combined systems, depending on the system concept. They thus form an important interface between the collector field, the heating system, and the heat consumption in the building.
Depending on the design, solar storage tanks can be used as hot water tanks, buffer tanks, hygienic tanks, or combi tanks with solar integration. It is crucial that the tank volume, heat exchanger, temperature range, insulation, and hydraulic integration match the planned solar thermal system.
Advantages of solar storage tanks
- Use of solar heat: Solar energy can be stored temporarily and used later in the building.
- Flexible system integration: Depending on the type of tank, applications for hot water, heating, or combined systems are possible.
- Suitable for modernization and new construction: Solar storage tanks can be integrated into new and existing heating systems.
- Structured selection: Storage tanks can be compared by volume, heat exchangers, insulation, and suitability for solar thermal systems.
Areas of application and target groups
Solar storage tanks are suitable for homeowners, self-builders, buyers with a background in heating/sanitary engineering, and technically interested end customers who want to plan, expand, or modernize a solar thermal system. Typical areas of application include single-family homes, renovations, new builds, and heating systems where solar energy is to be used for hot water preparation or heating support.
Important selection criteria for solar storage tanks
When selecting, particular attention should be paid to storage volume, storage type, number of heat exchangers, suitability for solar thermal systems, insulation, maximum temperature, maximum operating pressure, material, and drinking water suitability. For further system planning, additional collectors, solar accessories, buffer tanks or suitable Control technology may be relevant.
Note on professional sizing
The selection of a solar storage tank must match the collector area, the hot water demand, the heating load, the existing heating system, and the hydraulics. Information on volume, application area, or system compatibility is for orientation purposes and does not replace professional system planning.
Frequently Asked Questions about Solar Storage Tanks
What is a solar storage tank?
A solar storage tank is a thermal storage unit that absorbs heat from a solar thermal system and makes it usable for domestic hot water preparation, heating support, or combined systems.
What is a solar storage tank used for?
Solar storage tanks are used to utilize solar-generated heat at a later time. Depending on the system design, they can provide domestic hot water or support the heating system.
What is the difference between a solar storage tank and a buffer tank?
A buffer tank stores heating water for the heating system. A solar storage tank is designed for integration with a solar thermal system and, depending on the model, features suitable heat exchangers or connections.
Can a solar storage tank be combined with a wood heating system?
Yes, depending on the type of storage tank and the hydraulics, a solar storage tank can be combined with wood heating systems or other heat generators. The exact integration must match the system design.
How large should a solar storage tank be?
The right storage tank size depends on the collector area, hot water demand, heating system, user behavior, and the desired heating support. A blanket selection based only on living space is not sufficient.
What should I look for when comparing solar storage tanks?
Important factors are storage volume, storage type, number of heat exchangers, insulation, temperature range, operating pressure, material, and suitability for solar thermal systems.
Does a solar storage tank replace system planning?
No. A solar storage tank is an important system component, but it does not replace proper planning. Storage size, collector area, hydraulics, control, and safety technology must be designed to match.
