Vaillant eloBLOCK hot water central heating system, combinable with water storage tank

Special features of the Vaillant eloBLOCK:

Energy-efficient power consumption through optimal power adjustment

Ideal as an auxiliary heater, z.B. for peak load coverage in heat pump systems

Integration into existing heating systems is possible

A reliable alternative to gas wall-mounted boilers when no gas connection is available.

When additional heat is needed quickly, our technically and visually completely redesigned eloBLOCK electric heater is an excellent choice. For example, you can use it with a heat pump system to cover peak loads. It's equally well-suited for simple heating solutions in holiday homes or garden sheds. Its use in combination with photovoltaics is particularly sustainable. Thanks to its eBUS interface, the eloBLOCK can also be integrated into existing heating systems.

Quickly and easily to your desired temperature

With its high-efficiency pump, optimal power adjustment, and fine power gradations, our eloBLOCK electric heater is energy-efficient. 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 finely adjustable control and the precisely adjustable hot water temperature, you can quickly and conveniently reach your desired temperature at any time.

Installation instructions:

Devices with a 230V connection are supplied with either a Schuko plug or a hardwired connection (without a plug), depending on their power rating. In the case of a hardwired connection, a qualified electrician must be commissioned to carry out the installation.

For devices with a connection rating of 400V, a high-voltage connection (three-phase alternating connection) is necessary; installation may only be carried out by a registered specialist company, and the approval of the respective network operator must be obtained before initial installation.

For devices with a rated output exceeding 12 kW, you require the approval of your network operator. Please contact your network operator or an installation company listed in their installer directory for installation. This installation company will also assist you in obtaining the necessary approval from the respective network operator.
