Hygiene - buffer tank with 2 heat exchangers

Hygienic buffer tank with 2 heat exchangers – Efficient combination of instantaneous water heater and boiler

Innovative heat exchanger technology

This hygienic buffer storage tank impresses with its modern heat exchanger technology, in which an integrated stainless steel heat exchanger efficiently heats the drinking water as it flows through it. The system combines the advantages of an instantaneous water heater with the properties of a traditional boiler, ensuring continuous and rapid heating of your domestic water.

The large surface area of the stainless steel heat exchanger ensures precise and hygienic heat transfer. This brings the fresh water up to temperature immediately, while simultaneously minimizing the risk of legionella formation – an important aspect for your daily well-being.

Efficient use of the heating system

The buffer storage tank is ideal for absorbing excess heat from your boiler during transitional periods. This allows the resulting energy to be optimally utilized and released during periods of higher heat demand. This intelligent load balancing system contributes to the cost-effectiveness and sustainability of your heating system.

This storage system demonstrates its versatility, particularly when combined with various heat generators—such as oil, gas, solar, or heat pumps. The system can also be used with wood or coal boilers and other solid fuel systems, making it a future-proof investment for a variety of heating concepts.

Application recommendations

The hygienic buffer tank is particularly recommended when multiple heat generators are used or subsequently combined. It is ideal when frequent refilling of heating water is required in winter and supports smooth operation even with solid fuel boilers.

With its proven technology, the system offers a flexible solution for modern heating systems and ensures that sufficient hygienically clean domestic water is available at all times.

Robust and reliable – Technical data

Made of robust S235 steel, the buffer tank features a primed exterior and a raw interior, ensuring high durability. The insulating layer of polyester fiber fleece insulation with a RAL 9006 jacket ensures optimal heat loss.

The key features include a welded smooth tube exchanger made of steel pipe (1” IG) for solar applications and a 1 1/4" IG stainless steel heat exchanger for domestic water. With a total of 7 sockets (1 1/2" IG) and 4 filling sleeves (1/2" IG) and a venting sleeve, the storage tank meets the highest technical requirements.

The system's operating limits are a maximum pressure of 3 bar and a test pressure of 6 bar, while the operating temperature reaches up to 95° Celsius. These technical parameters underscore the device's high resilience and efficiency in use.
