wall hung combi gas boiler for central heating and D.H.W. preparation
antifreeze protection, protection against the pump blockageThe wall hung boilers ATTACK MAXIMUS RK Plus with modern design, equipped with the advanced technology with increased liability and construction quality.
The ATTACK MAXIMUS RK Plus are designed for central heating by high level of exchanger efficiency and very low emissions value, using the natural (G20) or liquefied gas (G31). They are equipped with the microprocessor control system.
Body of the RK Plus consists from the copper exchanger with a silicone treatment of surface, stainless steel 11-arm burner, that is equipped with an electronic ignition with ionisation flame control, modulation fan and modulation gas valve. The boilers can be connected to the external D.H.W. tank (additional).
