Reheating module | Instantaneous water heater 1 1/2" MDC 400 heating module

Reheating module/instantaneous water heater/emergency heating 1 1/2" MDC 400 – Reliable addition to your heating system

Product overview

This innovative reheating module offers a flexible solution for water heating in central heating systems. It is specifically designed for use in combination with photovoltaic systems, heat pumps, boilers, and other heating systems. The device supports operation by converting excess electricity into heat, thus making a sustainable contribution to energy optimization.

The sophisticated design combines technical efficiency with robust materials. This makes the reheating module a reliable solution that performs impressively even under exceptional heat requirements. It is ideally suited for flexible use in a variety of heating systems.

Advantages and features

The auxiliary heating module has a wide range of applications. It uses excess electricity, generated by a photovoltaic system, for example, to support the heating system. This ensures efficient use of available energy. The device also serves as an emergency solution if the main boiler, condensing boiler, or heat pump fails.

Another practical application is heating weekend or holiday homes even during the colder months. The module can also be used to charge a heating buffer tank, ensuring continuous, on-demand hot water production.

Technical details

The instantaneous water heater for central heating systems has precise connection options: The flow and return connection measures 1 1/4" IG, while the connection for the heating element is set to 1 1/2" IG. It reaches a maximum permissible operating temperature of 90 °C and operates safely up to an operating pressure of 10 bar.

The selection of suitable heating elements—available in 3.0 kW, 4.5 kW, or 6.0 kW at 400 V—offers flexibility for customizing the device to meet individual needs. The module's inner diameter is 60 mm, while its compact dimensions of 161 mm in diameter and 600 mm in length allow for easy integration into existing systems.

Possible uses and areas of application

The MDC 400 reheating module offers a wide range of applications – from emergency heating in the event of a power outage to heating backup during critical winter months. When used in combination with heat pumps or boilers, it makes an important contribution to the supply reliability of your heating system.

Its flexible use in open and closed heating systems, as well as its connection for heating cartridges up to 6.0 kW, make it an ideal add-on module. This allows for optimal cushioning of seasonal temperature fluctuations or planned maintenance work.
