Vaillant eloBLOCK VE 6/14–28/14 — a modern series of wall-mounted single-circuit electric boilers with heating outputs from 6 to 28 kW, designed for reliable and energy-efficient heating of residential and commercial spaces.

The boilers are suitable for radiator heating systems and underfloor heating applications and can also be connected to an external indirect hot water cylinder for domestic hot water production.

Thanks to microprocessor control and an intuitive interface, Vaillant eloBLOCK boilers provide easy and precise operation. The integrated eBUS communication system allows connection with Vaillant control systems and external controllers, enabling efficient heating management and enhanced comfort.

The eloBLOCK series is equipped with important safety and reliability functions, including frost protection, pump anti-blocking protection, temperature monitoring, a built-in expansion vessel, a mechanical pressure gauge, and a 3 bar safety valve.

With three-phase electrical connection 3×230 V / 400 V + N + PE, 50 Hz, high-efficiency circulation technology, and flexible installation options, Vaillant eloBLOCK VE 6/14–28/14 is an ideal solution as a primary heating source or a backup heating system for modern heating applications.
