Condensing, wall-mounted, dual-function gas boiler ECOCONDENS CRYSTAL II PLUS 25 kW WKD 4831 00 00 00

EcoCondens Crystal II Plus gas condensing boilers are high-class devices intended for both central heating installations and domestic hot water preparation. These boilers are suitable for heating both small and large surfaces (one of their main advantages is the ability to be combined into cascade systems). Perfect operation at minimum power makes the devices suitable even in small apartments, because they do not generate heat losses - the user pays for the energy actually used. Additionally, a significant reduction in minimum power reduces the number of ignitions, thanks to which the devices operate more smoothly without burdening other boiler components. This guarantees long-term and failure-free operation.
