  • equalisation of an inequal boiler output and higher comfort
  • lower fuel consumption – boiler works at full output, i.e. with optimal efficiency
  • long life of the boiler and chimney – minimum production of tars and acids at full ouput
  • option to combine with another means of heating (accumulation electricity, solar devices)
  • option to combine radiators with underfloor heating
  • higher comfort of operation
The accumulation tanks ATTACK HRS are made from the quality steel and serve for accumulation of the heating water as well as for preparation of the D.H.W. by an internal enameled exchanger. The ATTACK HRS1250K model is accessorized with an extra exchanger to be connected to the solar system. Tanks of this type have a built-in magnesium anode in the D.H.W. tank to increase resistance against corrosion.

ATTACK HRS: 10x socket G 1 1/2", 6x socket G 1/2", 2x socket G 1" – solar circuit, 2x socket G 1" – D.H.W.
