Product detailed description
Vaillant plastic bracket for the VR 40 module for eloBLOCK electric boilers
This plastic mounting bracket is an original Vaillant accessory designed for installing the additional electric VR 40 module directly into the construction of eloBLOCK series electric boilers. Vaillant's eloBLOCK electric boilers represent a flexible heating solution where a gas connection is not available - typically in recreational cottages, mountain chalets, or as a reliable backup or bivalent heat source in combination with a heat pump. Just like with gas condensing boilers, the standard functionality of eloBLOCK electric boilers can also be expanded with additional functions via the universal VR 40 module (for example controlling a domestic hot water circulation pump or a separate system pump), and it is precisely this bracket that ensures its safe and orderly installation inside the boiler body.
Since the construction of eloBLOCK electric boilers differs in many respects from gas condensing boilers (different arrangement of the heating elements, control electronics, and circulation pump), installing the VR 40 module requires a separately shaped bracket, different from the version intended for ioniDETECT boilers. This product is precisely the version adapted specifically for the eloBLOCK series.
Main features

- Easy installation without the need for special tools, by clicking or screwing into prepared mounting points in the boiler body.
- Maintains a clear and safe internal arrangement of the boiler without loosely placed additional electronics.
- Allows good access to the module for any future servicing or configuration changes.
Context - eloBLOCK electric boilers
The Vaillant eloBLOCK range of electric boilers is available in several output variants (roughly from about 6 kW up to 28 kW with output modulation), operating exclusively on electricity and supplying heat to radiators, underfloor heating, and domestic hot water tanks. Thanks to microprocessor control and fine output regulation steps, eloBLOCK operates economically, while the built-in high-efficiency circulation pump ensures fast and even heat distribution throughout the heating system. Typical applications of this boiler include buildings without access to natural gas, recreational and seasonal properties, or as an additional/backup heat source combined with a heat pump at lower outdoor temperatures, where the electric boiler can supplement the system's output.
In more complex eloBLOCK installations, where additional peripherals beyond the boiler's basic equipment need to be controlled (for example a domestic hot water circulation pump in a larger property), the same universal VR 40 module is used as with gas boilers - but with this differently shaped bracket that accounts for the electric boiler's construction.
Installation
Installing the bracket involves fixing it to the pre-prepared mounting points in the eloBLOCK boiler's construction, into which the VR 40 module itself is then inserted and secured. After mechanical fixing, the module is connected to the eBUS bus and any other necessary wires according to the chosen configuration of its two active functions. Installation is part of the standard installation of an electric boiler with an additional module, and we recommend entrusting it to a qualified electrician or service technician experienced with Vaillant electric boilers, since the work involves intervention in the boiler's electrical circuits.
Compatibility
The bracket is designed specifically for Vaillant eloBLOCK series electric boilers. For gas condensing boilers of the ioniDETECT generation, a differently shaped bracket is intended (a separate product in our range), since the internal layout of both boiler types differs significantly. Before ordering, we recommend verifying the exact model of your electric boiler to ensure correct dimensional compatibility of the bracket.
Typical use cases
This bracket is relevant for eloBLOCK electric boiler installations where the project includes additional functions of the VR 40 module - for example in larger recreational properties with a domestic hot water circulation circuit, or when connecting eloBLOCK as a bivalent source together with a heat pump, where control of an additional circulation pump or other peripheral may be needed. We recommend including it in the order together with the VR 40 module when planning the installation, so that the service technician has all the necessary components available in a single visit.
Why choose the original mounting component
The original plastic bracket is designed precisely for the dimensions of the VR 40 module and the construction of the eloBLOCK series, ensuring its secure attachment without the risk of mechanical damage or loosening during operation. Compared to an improvised solution (loose placement, double-sided tape), it offers significantly higher long-term reliability and a professional installation appearance, which will be especially appreciated by operators of facilities placing emphasis on the quality of the work performed.
Maintenance
The bracket requires no special maintenance. During regular servicing of the electric boiler, we recommend checking the firmness of the VR 40 module's attachment in the bracket and the condition of the connected wires.
Frequently Asked Questions (FAQ)
Is this bracket interchangeable with the version for ioniDETECT?
No, these are two structurally different parts adapted to the different internal layouts of ioniDETECT gas boilers and eloBLOCK electric boilers - always verify before ordering which boiler type you need the bracket for.
Is installing the bracket and module in an electric boiler more demanding than in a gas boiler?
The mechanical installation of the bracket itself is comparably simple, however working near the electric heating elements of the electric boiler requires increased caution and should be performed by a qualified electrician or service technician.
Can the VR 40 module in an electric boiler be used to control a circulation pump?
Yes, controlling the domestic hot water circulation pump is one of the available functions of the VR 40 module and can also be used in combination with the eloBLOCK electric boiler, if the given installation requires it.
Electric boiler as a bivalent source with a heat pump
eloBLOCK electric boilers are often used in practice as an additional (bivalent) heat source in combination with a heat pump - at very low outdoor temperatures, when the efficiency of the heat pump falls below an economically favorable level, the electric boiler can compensate for the missing output and thus ensure a comfortable indoor temperature even during the coldest days of the heating season. In such a setup, control of additional peripherals may be needed (for example a switching valve between sources or a separate circulation pump), for which the VR 40 module together with this mounting bracket is a suitable solution.
When designing such a bivalent setup, we always recommend consulting the exact control configuration with a designer, so as to ensure smooth and energy-efficient switching between the heat pump and the electric boiler according to current outdoor conditions.
Why electric boilers have a different construction than gas boilers
eloBLOCK electric boilers have no burner, flue gas path, or gas supply - their heat is generated exclusively by electric heating elements immersed directly in the heating water, controlled by microprocessor electronics with fine output modulation. This fundamentally different construction compared to gas condensing boilers is also reflected in the overall internal layout of the boiler body - a different arrangement of the control board, different routing of power cables to the heating elements, and a different layout of available mounting space for additional modules. This is precisely why the same VR 40 module mounting bracket cannot be used as with ioniDETECT gas boilers - the manufacturer has therefore developed a separate, geometrically different part precisely adapted to the internal layout of the eloBLOCK series.
This difference is particularly important for installers and service companies working with both types of Vaillant boilers - when ordering accessories, it is always necessary to specify the exact boiler type (gas ioniDETECT or electric eloBLOCK) to ensure the correct, compatible bracket is supplied.
Comparison of the two VR 40 bracket variants
| Feature | Bracket for ioniDETECT | Bracket for eloBLOCK |
|---|---|---|
| Boiler type | Gas condensing boiler | Electric boiler |
| Internal boiler construction | Burner, flue gas path, gas valve | Electric heating elements, no flue gases |
| Mounting location geometry | Adapted to the ioniDETECT control cabinet | Adapted to the eloBLOCK control cabinet |
| Interchangeability | Not interchangeable - different parts | Not interchangeable - different parts |
Always thoroughly verify the exact model of your boiler before ordering, to ensure you obtain the correct, compatible bracket variant.
Operating economics of an electric boiler with additional functions
eloBLOCK electric boilers are more expensive to operate per unit of heat produced than gas condensing boilers or heat pumps, since the price of electricity per kWh of heat is generally higher than for gas or when using a heat pump with its coefficient of performance. This is precisely why eloBLOCK is most often used in practice where alternative sources are not available (no gas connection) or as an additional/backup source with limited operating time during the year. In such cases, it makes sense to invest in additional functions (for example a domestic hot water circulation pump controlled by the VR 40 module) especially when they genuinely increase comfort or the efficiency of using the electric boiler's limited operating time, since every additional function should also be considered in terms of the benefit-to-overall-operating-cost ratio of electric heating.
Additional frequently asked questions
Is the bracket suitable for all eloBLOCK output variants (VE 6 to VE 28)?
The control cabinet and internal layout are generally similar across the eloBLOCK output range, however we recommend verifying compatibility with the specific model and its version with our technical team before ordering.
Does the VR 40 module make sense even for an electric boiler used only as a backup source?
It depends on the specific need - if you need to maintain, for example, domestic hot water circulation even while the backup electric boiler is operating, the VR 40 module will ensure this function just as reliably as with the main heat source.
Practical recommendation when ordering a complete set
When ordering an eloBLOCK electric boiler with a planned additional function (for example domestic hot water circulation in a recreational property with multiple bathrooms), we recommend including in a single order the boiler of the selected output, the VR 40 module, this mounting bracket, and possibly related control technology accessories (room thermostat, outdoor sensor for weather-compensated control, etc.). A complete order allows the service technician to carry out the entire installation in a single visit, which is especially advantageous for more remote recreational properties, where a second service visit due to a missing part would mean significant additional time and travel costs.
Service companies with many years of experience with Vaillant electric boilers confirm that this type of small but easily overlooked accessory is one of the most commonly purchased items after the first installation visit if it was not included in the original order - we therefore recommend paying attention to it already at the project planning stage.
Recreational and seasonal properties - specific context of use
In a large proportion of cases, eloBLOCK electric boilers are installed precisely in recreational cottages, mountain chalets, or seasonally occupied properties, where it is not economically advantageous to build a natural gas connection due to the limited annual usage time of the property. In such conditions, there is increased emphasis on simple and reliable operation without the need for frequent service interventions, since the property may be unattended for most of the year and any fault could remain unnoticed for a longer period. This is precisely why it is important for the additional electronics (including the VR 40 module) to be installed safely and reliably using original accessories, which minimize the risk of mechanical loosening or damage during longer unattended periods.
For seasonal properties, we also recommend performing a functionality check of all configured additional VR 40 module functions at the start of each heating season, to ensure their reliable operation throughout the period the property is used, including a visual check of the firmness of this mounting bracket and the condition of the wires connected to it after any longer period without boiler operation, ideally as part of a regular annual service inspection carried out by a qualified technician.
Summary
This plastic bracket is an original Vaillant accessory that allows for the safe and orderly installation of the VR 40 module into the construction of eloBLOCK electric boilers. It is a small but functionally important part of any installation combining this electric boiler with additional VR 40 module functions, whether it is a standalone installation in a recreational property or a bivalent setup with a heat pump. Thanks to its precise adaptation to the eloBLOCK construction, it represents a more reliable alternative to improvised module placement and a recommended addition to your order.
