An accumulation tank can store a large amount of water. It can be combined with various heating methods (wood boilers, electricity, solar devices, or heat pumps); a combination with radiators and underfloor heating is of course also possible. Tank volumes range from 204 to 4,940 liters. Heat retention is ensured by 100 mm thick insulation made of polyester fibers with a leatherette cover. Thanks to its properties, it primarily extends the service life of not only the boiler but also the chimney.
Standard accumulation tank
ATTACK AK, AS
It accumulates excess energy from the heating element and subsequently uses it later according to your needs. Compared to the basic clean AK tank, the ATTACK AS model is equipped with one heat exchanger, which you can easily connect to a solar system.

Accumulation Tank with internal cylinder
ATTACK HR, HRS
It accumulates water not only for CH but also for DHW, as it contains an internal enameled cylinder. To increase the corrosion resistance of the DHW cylinder, we used a special magnesium anode.

Accumulation Tank with solar heating option
ATTACK TUV, TUVS
They accumulate water for CH and DHW. A stainless steel coil is used in these tanks for faster heating, which ensures rapid DHW heating thanks to the stainless steel coil.
