## Long description

Rittal SK 3212.024 is a vertical, tankless instantaneous combi boiler system designed for installation in demanding environments. The unit provides compact heating with flexible mounting and water connection options, and allows for partial or fully internal mounting in enclosures or machinery cabinets.
Advantages
The compact vertical design saves installation space while delivering output in the range of 375–5,000 W suitable for localized heating needs. Tankless operation offers on-demand hot water without storage losses, and multiple mounting and water-connection options simplify integration into control cabinets or technical rooms. The unit supports precise temperature control with a thermostat range up to 70 °C.
Suitable for
 Heating small enclosures, control cabinets or machine housings
 Applications requiring on-demand hot water and space heating
 Installations where compact vertical mounting and flexible connections are needed
When it may not be suitable
Because the unit is designed for outputs between 375 and 5,000 W and is a tankless combi system, it may not be appropriate for large-volume domestic hot-water systems or central heating of whole buildings. Environments requiring temperatures above 70 °C or continuous high-flow domestic hot-water supply could require a different solution.
