PV instantaneous water heater heating module emergency heating 1 1/2" MDC 400P

Reheating module/instantaneous water heater/emergency heater 1 1/2" MDC 400P – Reliable auxiliary heater for your system

Product overview

The MDC 400P backup heating module is an innovative add-on module specifically designed for open and closed heating circuits. It offers an effective emergency heating solution in the event of boiler or heat pump failures, ensuring comfortable warmth even in unexpected situations.

Furthermore, the module can be used to supplement heating at low outdoor temperatures and allows excess energy from a private photovoltaic system to be used for central heating. The system thus combines modern technology with high flexibility.

Advantages and features

A key advantage of the MDC 400P is its low purchase price, making it a cost-effective retrofit solution. Its quick installation and small footprint allow for easy integration into existing heating systems.

The highly insulated housing, consisting of an inner layer of raw steel and an outer powder-coated plastic shell, ensures safe and efficient heat transfer. Furthermore, the high-quality 50 mm thick polyurethane foam insulation provides optimal heat retention.

Technical details

The module has connection options of 1 1/4" IG for flow and return as well as 1 1/2" Internal thread for the heating element. It operates at a maximum permissible operating temperature of 90 °C and an operating pressure of up to 10 bar, making it versatile and robust.

With a minimum flow rate of 9.0 kW or 514 l/h and an inner diameter of 60 mm, the reheating module meets stringent technical standards. The matching MDC400 Plus heating element module with 9.0 kW (400V) is also available, while its dimensions of 161 mm in diameter and 850 mm in length ensure a compact design.

Possible uses and areas of application

The MDC 400P backup heating module offers a wide range of applications – from emergency heating in the event of a system failure to supplemental heating during critical winter months. When used in combination with heat pumps or boilers, it makes a significant contribution to the reliability of your heating system.

Its flexible applicability in open and closed heating systems, as well as its compatibility with heating elements up to 9.0 kW, makes it an ideal add-on module. This allows for optimal compensation of seasonal temperature fluctuations or planned maintenance work.
