Vaillant electrical heating device Eloblock including high-efficiency pump

Vaillant hot water central heating eloBLOCK combinable with water storage tank

Special features of Vaillant eloBLOCK:

• Economical power consumption through optimal power adjustment
• Ideal as additional heating, z.B. for peak load coverage in heat pump systems
• Integration into existing heating systems possible
• Reliable alternative to gas wall heaters when no gas connection is available

If additional heat needs to be available quickly, our completely redesigned eloBLOCK electric heater is a good choice. For example, you can use it with a heat pump system to cover peak loads. It's equally well-suited for a simple heating solution in holiday homes or garden homes. It's particularly sustainable when combined with photovoltaics. Thanks to its eBUS interface, the eloBLOCK can also be integrated into existing heating systems.

With its high-efficiency pump, optimal power adjustment, and fine power adjustment, our eloBLOCK electric heater is economical in its power consumption. Intelligent technical details such as the safety temperature limiter and the built-in frost protection function ensure maximum operational reliability at all times.

With the fine-tuned control and the hot water temperature that can be adjusted to the exact degree, you can quickly and easily reach your comfortable temperature at any time.

Technical data Vaillant eloBLOCK:

A notice:

Weather-compensated controller VRC 700 or VRC 720 must be ordered separately if the eloBLOCK is used purely as a heating device.
When combining an eloBLOCK with a heat generator, a VR 32B module is required.

Installation instructions:

Depending on the power rating, devices with a 230V connection are supplied with a Schuko plug or a fixed connection (without a plug). In the case of a fixed connection, a specialist tradesman must be commissioned for installation.

For devices with a connected load of 400V, a high-voltage connection (three-phase alternating current connection) is required. Installation may only be carried out by a registered specialist company, and approval from the relevant network operator must be obtained before initial installation.

For devices with a rated power of more than 12 kW, you will need approval from your grid operator. Please contact the grid operator or an installation company listed in the grid operator's installer directory for installation. This installation company will also assist you in obtaining the necessary approval from the respective grid operator.

In accordance with the EU Ecodesign Directive 2009/125/EC, Regulation 2015/1188 laying down ecodesign requirements for local space heaters was adopted. Installation and commissioning of electric local space heaters is only permitted in combination with an external room temperature control system that fulfills the following functions:
