Kotlin Ecorazem CRYSTAL II PLUS 20 kW - wall-hung, dual-function condensing gas boiler with high energy efficiency
EcoCondens Crystal II Plus gas condensing boilers are high-performance appliances designed for both c.o. as well as for the preparation of c.w.u. These boilers are suitable for heating both small and large areas (one of their main advantages is that they can be combined in cascade systems). Excellent operation at minimum power makes the devices suitable even in apartments with small space, as they do not generate heat loss - the user pays for the energy actually used. In addition, a significant reduction in the minimum power reduces the number of ignitions, making the equipment run more smoothly, without putting a strain on other boiler components. This guarantees long-term and trouble-free operation.- energy class: A- oPEN-THERM communication system - remote control of boiler parameters from the position of the room regulator- modern heat exchanger with high efficiency - exchanger in the form of a single coil made of stainless steel- possibility to work in a cascade system (max. up to 5 boilers)- high-efficiency circulation pump- fan with variable speed control (electronically controlled)- stainless steel cylindrical burner with low NOx emissions (class 6)- hydraulic group in the form of hydroblock mounted on quick couplings- complete security system- ability to work with multi-zone modules for heating systemsDo you need help?
