Produktbeschreibung

The CerastarComfort ZWR 18-7 KE 23 is a wall-mounted gas-fired warm-water boiler with a wide adjustable heating range (8.9–17.8 kW) and a maximum heat output of 20.2 kW. It supports Erdgas E/H and, with a separately ordered kit, Flüssiggas. The unit includes a stainless steel heat exchanger block, built-in condensing-style water heating, and an AGÜ exhaust gas monitoring system. It offers continuous hot water at a stable temperature when a tap is opened and provides a COM/ECO switch for immediate hot water delivery or energy-saving operation. The boiler is designed for quick serviceability and easy retrofitting due to standard connections, and it is compatible with both top- and front-mounted installation plates. Optional CR series room temperature regulators (CR 100, CR 120) and a TA outdoor sensor enable tailored control, including room-temperature and external-temperature regulation. The device is suitable for low-temperature operation and underfloor heating, with a safety valve, expansion vessel, automatic vent, and a 24 V DC control circuit. Maintenance-friendly features include a built-in fault memory and diagnostic options for service and troubleshooting. The system requires professional installation and must be adapted to local gas type before commissioning.
