Instantaneous water heater emergency heating MDC 400 plus heating element 3 kW

Complete package: MDC 400 reheating module plus 3 kW electric heating element – ​​Efficient heating solution

Product overview

The complete package combines the versatile MDC 400 after-heating module with a powerful 3 kW heating element. It is ideally suited as a flexible addition to existing heating systems and reliably provides extra heat when needed.

With its quick installation, small footprint and robust construction, this system is ideal for use in new buildings, modernizations and in the event of short-term failures of the main heat source.

Areas of application and use

The MDC 400 auxiliary heating module integrates seamlessly into open and closed heating circuits and can be used for both continuous support and emergency heating. It helps to efficiently utilize excess energy, for example from photovoltaic systems, to meet heating demands.

Ideally suited for use in weekend and holiday homes, the system ensures a continuous heat supply even in the event of maintenance or failures of boilers, condensing boilers or heat pumps.

Technical features and equipment

The module features an insulated raw steel housing with a protective, powder-coated outer shell in gray. The 50 mm thick polyurethane foam insulation ensures efficient operation and a long service life.

Equipped with a 1 1/2" The internal thread connection for the heating element offers flexible application possibilities, while a maximum operating temperature of 90 °C and an operating pressure of up to 10 bar ensure safe applications.

Performance variants and minimum flow rate

The heating element of the complete package is available in different power classes, specifically designed for 1.5 kW, 2.0 kW, 3.0 kW at 230 V and 4.5 kW, 6.0 kW and 9.0 kW at 400 V. These variants allow for optimal adaptation to the individual energy requirements of the heating system.

The minimum flow rates – 86 l/h for 1.5 kW, 114 l/h for 2.0 kW, 171 l/h for 3.0 kW, 257 l/h for 4.5 kW, 343 l/h for 6.0 kW and 514 l/h for 9.0 kW – guarantee efficient heat transfer and smooth operation even with varying heat demand.

Advantages and added value

With low acquisition costs and straightforward installation, the system offers high added value. Its compact design and robust construction make it particularly attractive for confined installation spaces and rapid deployment.

Whether as a complement to renewable energy systems or as a reliable emergency solution, the complete package sustainably improves energy efficiency and increases living comfort.

Heating cartridge – Efficient addition for hot water and heating

The 3 kW heating element is specifically designed for use in domestic hot water and water storage tanks. It ensures precise temperature control and thus provides a constant heat supply in both residential and commercial applications.

Thanks to the high-quality workmanship using stainless steel and robust plastic, the heating cartridge is not only durable, but also resistant to corrosion and high temperatures.

High-quality materials and safety

The use of stainless steel and an Alloy 825 heating coil guarantees the highest material quality. The white plastic housing further enhances the product's attractive appearance.

An integrated thermostat housing allows for precise temperature control in the range of 5 to 75 °C, while a safety temperature limiter at 93 °C provides additional protection against overheating.

Easy installation and reliable protection

The simple integration of the heating element into existing storage tanks is facilitated by the 1 1/2" It features an external thread connection and a compact installation length of 420 mm. A 1.5-meter-long connection cable also allows for easy power supply.

In addition, both components meet the relevant safety standards: The reheating module boasts IP44 protection, while the heating cartridge is protected against splashing water according to IPX4. With a maximum operating pressure of 10 bar, both solutions are ideally equipped for demanding operation.

Conclusion: Efficient heat of the highest quality

The complete package MDC400 reheating module plus 3 kW heating element combines versatile application possibilities with modern technology and ease of use. It offers flexible heating solutions for a wide range of applications and guarantees reliable support when it matters most.

With its high-quality materials, energy-efficient operation and easy installation, this system is the ideal solution for sustainably optimizing the comfort and functionality of existing heating systems.
