MDC 230 – Efficient heat support

Product overview

The Post-heating module - instantaneous water heater The MDC 230 offers a reliable and flexible addition to existing heating systems. It can be easily integrated into both open and closed heating circuits and serves as a backup solution or as supplementary support to the main heating system.

This module ensures continuous comfort, especially during periods of increased demand or when conventional heat sources fail. With its quick installation and small footprint, it is ideally suited for both new builds and renovations.

Advantages and added value

The Post-heating module - instantaneous water heater The MDC 230 impresses with its low purchase price and quick installation. The insulated housing and compact design ensure a small footprint, which is also advantageous in confined installation spaces.

Whether as a supplement to a photovoltaic system or as a backup in case of a main heating system failure – the module delivers reliable and energy-efficient heat. Its easy integration into existing systems increases living comfort and supports a sustainable heating strategy.

Technical details

Equipped with a connection for a 1 1/2" IG, the module impresses with its robust construction and insulated housing. The interior is made of raw steel and protected by a powder-coated outer shell, ensuring durability.

Insulation is achieved using 50 mm thick polyurethane foam, which contributes to energy-efficient operation. Further technical specifications include a maximum operating temperature of 90 °C and an operating pressure of up to 10 bar, guaranteeing safe use in a wide variety of systems.

The module is compatible with heating elements of different power classes, namely 1.5 kW, 2.0 kW and 3.0 kW at 230V. This flexibility allows for optimal adaptation to the individual energy requirements of the heating system.

The minimum flow rates vary depending on the power output: from 86 l/h for 1.5 kW, 114 l/h for 2.0 kW and 171 l/h for 3.0 kW. This ensures that the heating system operates efficiently even with varying heat demand.

Areas of application and use

The Post-heating module - instantaneous water heater The MDC 230 is used in systems that rely on solid fuels, gas, oil, or heat pumps. It supports the heating circuit by utilizing excess energy – for example, from a photovoltaic system – to cover heating demands.

Its versatility makes it Post-heating module - instantaneous water heater It is the ideal solution for weekend and holiday homes where an additional heating option is needed. It is also used as a temporary solution during maintenance or when boilers, condensing boilers, or heat pumps are defective.
