Product information

Description

Electric Boiler KOSPEL EKCO.LN3 series with simplified control and expansion diaphragm vessel 400 V (models 12/16/20/24) is a three-phase electric boiler designed to supply heat to central heating systems in residential and small commercial buildings. The unit integrates basic temperature control and a factory-attached diaphragm expansion vessel to accommodate thermal expansion and help stabilise system pressure. Available in four power outputs — 12, 16, 20 and 24 kW — it is intended for installations where a compact electric heat source with simplified operation and an integrated expansion vessel is required.

Advantages

The EKCO.LN3 boiler offers straightforward operation with simplified control logic that supports reliable temperature regulation without complex settings. Inclusion of an expansion diaphragm vessel reduces the need for a separate external tank, saving installation space and simplifying commissioning. Three-phase 400 V power supply ensures even load distribution and efficient electric heating performance in multi-zone or higher-demand systems. The compact housing and factory-mounted hydraulic connections enable a neat, space-saving installation.

Suitable for

  • Residential central heating systems with electric-only heat source
  • Small commercial premises requiring electric heat without combustion
  • Retrofit projects where space for a separate expansion vessel is limited
  • Installations with available 400 V three-phase supply

Key specifications

  • Supply voltage: three-phase 400 V
  • Available power outputs: 12 kW, 16 kW, 20 kW, 24 kW
  • Built-in simplified control for temperature regulation
  • Factory-attached diaphragm expansion vessel for pressure compensation
  • Compact housing suitable for wall-mounted or dedicated utility-room installation
  • Intended for closed central heating systems

How to use

Mount the boiler according to applicable local regulations and the manufacturer’s installation instructions, ensuring a reliable three-phase 400 V supply and proper hydraulic connections to the heating circuit. After mechanical and electrical installation, bleed the system to remove air, check the expansion vessel pre-charge and system pressure, then set the required temperature using the simplified control interface. Monitor system pressure and temperature during initial operation to confirm stable performance and adjust settings as needed within the basic control functions.

Usage recommendations

Use the EKCO.LN3 boiler in closed central heating systems with correctly sized piping and safety accessories. Verify that the system’s hydraulic layout, pump capacity and safety devices correspond to the selected boiler power. Periodic inspection of the expansion diaphragm vessel pre-charge and overall system pressure is recommended to maintain reliable operation.
