GROHE Red Duo kitchen boiling water system, brushed hard graphite, tap valve and 4 l boiler, access only to boiling water, safety lock, spout swivel angle type C 150°, filter included 30085AL1

The GROHE Red Duo system is a comprehensive solution for the kitchen, combining the functionality of a traditional kitchen faucet with instant access to boiling water. Ideal for both domestic and commercial use, this system enhances comfort and efficiency in cooking and everyday tasks.

Comfort and functionality in one

GROHE Red Duo offers the convenience you need in a modern kitchen. Thanks to a 4-liter boiler (3 liters of 100°C boiling water), you always have hot water on hand for preparing tea, coffee, instant soups, or blanching vegetables. The C-spout with a 150° swivel range provides freedom of movement and makes working at the sink easier. Additionally, the faucet is equipped with a GROHE ChildLock safety lock, which prevents accidental activation of the boiling water – particularly important in homes with children.

Construction and durability

The GROHE Red Duo system is characterized by a solid construction and high-quality workmanship. Durable materials guarantee long-term use, and the GROHE Long-Life coating provides resistance to damage and ease of cleaning. The boiler is equipped with TÜV-certified triple electronic protection, minimizing the risk of uncontrolled operation. The power connection is made via a hose (cable gland), and the size of the power connection is 3/8 inch.

Filtration and protection

The system includes an S filter, which protects the boiler from limescale deposits and extends its lifespan. This filter is efficient – it ensures the passage of up to 600 liters of water with a hardness of 20° dKH. A backflow preventer compliant with EN 1717 standard (class AA) further increases safety. The system operates at a minimum pressure of 1 bar and a maximum flow rate of 8 l/min at a pressure of 300 kPa.
