Heat storage
ATTACK buffer tanks store thermal energy, stabilise heat-source operation and support efficient heating-system control.
Product ranges
Each model has its own applications, output range and design. Below is an overview of the main differences; full specifications and documents are available on each product page.
Standard buffer tank
Heat storage for boilers and heating systems.
The ATTACK AK tank stores excess heat from a heat source and releases it to the system as needed. The AS version adds one heat exchanger for connecting a solar system. Actual model capacities range from 204 to 4,940 litres.
Buffer tank with DHW cylinder
Heating-water storage and 160 l of domestic hot water.
The HR and HRS tanks combine heating-water storage with an internal enamelled 160-litre domestic hot water tank. A magnesium anode protects the tank from corrosion; the HRS range also includes a solar heat exchanger.
Buffer tank with domestic hot water heating
Heat storage with on-demand domestic hot water heating.
The ATTACK TUV and TUVS tanks heat domestic hot water on demand through a stainless-steel coil. TUVS also includes a lower heat exchanger for an additional heat source. Actual model capacities range from 474 to 1,960 litres.
