Accumulation tank with cylinder ATTACK HR, HRS, in addition to accumulating heating water, also takes care of domestic hot water production, as it contains an internal enameled cylinder. To increase the corrosion resistance of the DHW cylinder, we used a special magnesium anode. A manual air release valve is located in the upper part of the tank.
Accumulation tank with cylinder HR and HRS
A big advantage of the accumulation tank is the use of the full power of the boiler with higher efficiency. The accumulation tank is robotically welded, extending its service life. By using an accumulation tank, you increase the service life of the boiler and chimney. When used, you consume less fuel and reduce the formation of acids and tar during combustion. You can choose tanks with a volume of 445 – 1,800 liters, which come with a built-in internal cylinder with a volume of 160 liters.

Accumulation tank with cylinder and heating methods
The accumulation tank can be combined with various heating methods (accumulation electricity, solar devices, or heat pumps); a combination with radiators and underfloor heating is of course also possible.
Thermal insulation
So that your accumulation tank preserves heat better. Every standard ATTACK HR and HRS accumulation tank comes with a soft removable insulation layer included in the price of the tank. 100 mm thick insulation made of polyester fibers with a leatherette cover is attached to the tank after installation, and the insulation takes care of the rest.
At full power and optimal efficiency, you consume less fuel
The advantage of connecting a boiler with an accumulation tank is its operation at rated power, achieving a minimal amount of tar and acids during combustion and consequently a long service life of the boiler and chimney.
