Buffer storage tank
Buffer storage tanks store excess heat from heating systems and make it available again at a later time. They are particularly suitable for wood heating, pellet boilers, heat pumps, solar thermal systems, and combined heating systems where heat generation and heat demand do not always occur simultaneously.
In the GEMA Shop you will find buffer storage tanks for various volume ranges, system concepts, and application areas – suitable for renovation, new construction, heating modernization, and the hydraulic integration of modern heat generators.

Choosing the right buffer storage tank
Buffer storage tanks are central heat storage units for water-based heating systems. They absorb excess heating energy and release it back to the heating system when needed. This allows heat generators to operate more evenly and the heat supply to be better adapted to actual demand.
Buffer storage tanks play an important role especially with wood heating systems, pellet boilers, heat pumps, and solar thermal systems. With wood heating systems, they can absorb excess heat from the combustion process. With heat pumps, they can contribute to system stability depending on the hydraulics. In combination with solar thermal systems, they support the use of solar-generated heat in the heating system.
Advantages of buffer storage tanks
- Intermediate heat storage: Excess energy can be absorbed and used later.
- Stabilize system operation: Buffer storage tanks help to better coordinate heat generators, heating circuits, and consumers hydraulically.
- Flexible integration: Depending on the design, they are suitable for wood heating systems, heat pumps, solar thermal systems, or combined systems.
- Better system planning: Storage size, heat exchanger, insulation and connections can be selected to match the heating system.
Areas of application and target groups
Buffer storage tanks are suitable for homeowners, DIY enthusiasts, HVAC-related buyers and technically interested end customers who want to plan, expand or modernize a heating system. Typical areas of application are single-family homes, multi-family homes, existing systems, wood heating, pellet systems, heat pump systems and heating systems with solar support.
Important selection criteria for buffer storage tanks
When selecting, special attention should be paid to storage volume, storage type, number of heat exchangers, insulation, maximum operating pressure, maximum temperature, material and suitability for specific heat generators. For further system integration, storage technology, heat pump storage tanks, solar storage tanks or suitable Heating accessories & system technology be relevant.
Note on professional sizing
The size and design of a buffer storage tank must match the heat generator, the heating load, the system volume, the hydraulics, and the desired operating behavior. Volume specifications and application recommendations are for orientation purposes and do not replace professional system planning.
Frequently asked questions about buffer storage tanks
What does a buffer storage tank do?
A buffer storage tank stores heating water and absorbs excess heat from the heating system. This heat can later be released to heating circuits or consumers.
When is a buffer storage tank useful?
A buffer storage tank is particularly useful when heat generation and heat demand do not match in time. This often applies to wood heating systems, pellet boilers, heat pumps, and solar thermal systems.
Which buffer storage tank is suitable for a wood heating system?
For wood heating systems, the buffer storage tank must match the boiler output, burn behavior, heating load, and system concept. The appropriate storage tank size should be professionally designed.
Can a buffer storage tank be combined with a heat pump?
Yes, buffer storage tanks can be combined with heat pumps depending on the system hydraulics. It is important that the storage tank size, temperature range, and integration match the operating mode of the heat pump.
What does the number of heat exchangers on the buffer storage tank mean?
Heat exchangers enable the integration of additional heat sources, for example solar thermal systems. Whether a buffer storage tank with or without a heat exchanger makes sense depends on the planned system configuration.
What should I pay attention to when comparing buffer storage tanks?
Important factors are storage volume, installation height, insulation, operating pressure, maximum temperature, connections, heat exchangers, and suitability for wood heating, heat pumps, or solar thermal systems.
Does a buffer storage tank replace heating system planning?
No. A buffer storage tank is an important system component, but it does not replace proper planning. Hydraulics, storage tank size, safety equipment, and heat generators must be appropriately designed.
