9 kW immersion heater IU-311 218003

Electric water heater – a reliable source of heat

The NIBE IU-311 9 kW immersion heater is an efficient and reliable device designed for heating water in various types of tanks. It is suitable for both domestic and industrial installations where quick and effective water temperature increase is required. The construction based on a copper heating element guarantees good thermal conductivity and long life.

Construction and application

The NIBE IU-311 heater is designed to operate in systems where additional water heating is needed, e.g. in domestic hot water tanks, boilers or buffer tanks. Its versatility results from the possibility of powering it with both 230 V and 400 V, which allows it to be adapted to the existing electrical installation. The flange diameter of 50 mm ensures compatibility with most standard mounting holes. The immersion depth of 400 mm allows for efficient heating of even large amounts of water.

Key features and benefits

• High power: 9 kW power ensures rapid water heating, which is particularly important when a large amount of hot water is needed in a short time.
• Universal power supply: The possibility of powering with 230 V or 400 V increases installation flexibility and allows adaptation to the existing electrical infrastructure.
• Durable construction: The copper heating element is characterized by high corrosion resistance and long life, which translates into the reliability of the device.
• Standard flange size: The 50 mm flange diameter ensures easy mounting in most available tanks.
• Wide application: Ideal for domestic applications (domestic hot water heating) and industrial applications (technological processes requiring heated water).
• Safety: The lack of a built-in temperature limiter requires the use of external thermal protection in the installation – this is a standard solution for this type of heater, giving full control over the safety system.

The NIBE IU-311 heater is a solid choice for both professionals involved in heating installations and for users looking for a reliable heat source for their homes. Its versatility and high quality of workmanship guarantee long-term and efficient operation.
