Vaillant eloBLOCK Electric Boiler VE 21/14 EU I

The eloBLOCK electric boiler is perfect as a backup heating solution when extra heat or hot water is needed. It is small and compact, available in 3 power sizes (9.0, 14.0, and 21.0 kW) and has many uses: e.g., for heating a summerhouse/allotment house, as a backup for hot water production or heat pump systems, and in combination with solar panels. The lightweight, compact electric boiler operates in principle like a gas boiler, just with a different energy source, and it can be installed anywhere—quickly. For large demands, it can also be installed in cascade. eloBLOCK saves electricity through optimal performance adaptation and intelligent technical details such as safety temperature limiter and built-in frost protection, ensuring high operational reliability. The built-in control is easy to operate and allows for precise room and hot water temperature settings. eloBLOCK has integrated pressure expansion, low energy pump, manometer, and safety valve. Hot water prioritization is sold separately and mounted externally.
