Vaillant complete connection accessory set for ecoCOMPACT/auroCOMPACT
Code: 0020170492Product detailed description
Complete connection accessory set for Vaillant ecoCOMPACT and auroCOMPACT
This set represents the complete original connection accessories for Vaillant stationary condensing boilers with an integrated domestic hot water storage tank from the ecoCOMPACT (VSC and VCC models) and auroCOMPACT (VSC D) ranges. It comprises all the fittings needed to connect the boiler body to the heating circuit, the domestic hot water circuit, and the gas supply in one place, supplied as a single, clear set instead of several separately ordered parts.
The set includes shut-off valves for both the heating and DHW circuits, a filling valve for topping up the heating water, two safety valves with different opening pressures corresponding to their respective circuits (3 bar for the heating circuit, 10 bar for the domestic hot water circuit – these two circuits have different operating pressures in the ecoCOMPACT/auroCOMPACT design, and therefore also different safety equipment), a gas supply connection with a shut-off valve, and finally drain hoses for the safe discharge of any water released from the safety valves.
Technical characteristics
- Intended for: Vaillant ecoCOMPACT (VSC, VCC) and auroCOMPACT (VSC D) stationary condensing boilers with an integrated domestic hot water storage tank
- Shut-off valves: for both the heating circuit and the domestic hot water circuit, allowing the boiler body to be disconnected from the system without draining the entire installation
- Filling valve: for topping up heating water in the system
- Heating circuit safety valve: opening pressure 3 bar
- Domestic hot water circuit safety valve: opening pressure 10 bar
- Gas connection: including a shut-off valve, in compliance with applicable gas appliance regulations
- Drain hoses: for safely discharging water released by the safety valves to a suitable location (e.g. a floor drain)
- Fitting material: brass, corrosion-resistant under normal operating conditions
- Max. operating temperature: up to 120 °C
Why this set is a practical choice
Stationary boilers with an integrated storage tank, such as ecoCOMPACT and auroCOMPACT, require complete safety and connection equipment for two separate circuits simultaneously during installation – the heating circuit and the domestic hot water circuit – which have different operating parameters and therefore different requirements for safety valves. Instead of separately sourcing and ordering individual valves, a gas connection, and drain hoses from various suppliers, Vaillant offers this complete set as a single functional unit, guaranteeing mutual compatibility of all components as well as compliance with the technical parameters of the specific boiler.
This set is also standardly listed as part of the recommended accessories when selling complete boiler packages with a control unit (for example in combination with multiMATIC 700), since without it the boiler installation cannot be legally and safely completed – it is therefore practically essential accessory for every new installation of this type of boiler.
We therefore recommend that customers ordering an ecoCOMPACT or auroCOMPACT boiler always check whether this set is already included in the price of the chosen package, or whether it needs to be added to the order as a separate item.
Installation
The set must be installed exclusively by an authorised person qualified to install gas and heating appliances. The individual components of the set are fitted to the corresponding connection ports of the boiler body according to the manufacturer's installation instructions – the heating circuit shut-off and safety valves on the heating side, the 10 bar safety valve and related fittings on the domestic hot water circuit side, and the gas connection with valve on the gas inlet to the boiler. Commissioning also includes connecting the drain hoses to a safe location and performing a functional test of both safety valves and the shut-off fittings.
We recommend installing this set at the same time as the boiler body itself, as some components (particularly the safety valves and shut-off fittings) are fitted directly to the boiler's connection ports before it is finally positioned and connected to the building's piping.
Compatibility
The set is intended for Vaillant stationary condensing boilers with an integrated domestic hot water storage tank from the ecoCOMPACT range (e.g. VSC 206/4-5 90, VCC 206/4-5 150, and related models) and the auroCOMPACT range (VSC D). Due to the specific design of the connection ports on these boilers, the set is not interchangeable with connection accessories intended for other Vaillant boiler ranges (such as the wall-mounted ecoTEC or stationary ecoVIT), which have a different domestic hot water preparation concept and different connection dimensions.
Maintenance and care
As part of the boiler's annual service inspection, we recommend checking all components of this set:
- the functionality of both safety valves (3 bar and 10 bar) by manual testing according to the manufacturer's instructions,
- the tightness of the shut-off and filling valves,
- the condition and patency of the drain hoses,
- the tightness of the gas connection and the functionality of its shut-off valve,
- a visual check for corrosion or mechanical damage to the individual fittings.
Since the set contains safety elements on two different circuits (heating and domestic hot water) as well as a gas connection, we recommend not neglecting this inspection and entrusting it exclusively to an authorised service technician.
Neglecting to check these components can lead not only to operational faults but also to safety risks, as they are components directly connected to the gas supply and the safety equipment of the boiler's pressurised circuits.
Why choose a genuine Vaillant part
An original set guarantees that the safety valves have a precisely defined, manufacturer-verified opening value corresponding to the respective circuit (3 bar heating, 10 bar domestic hot water), and that all components of the set are mechanically and functionally compatible with each other. Assembling an equivalent set from individually purchased parts from various manufacturers carries the risk of an incorrect combination of opening values or incompatible connection dimensions, which is not advisable to risk with safety components of this type, especially on a boiler with an integrated storage tank, where the safety equipment simultaneously protects a larger volume of domestic hot water within the boiler's body.
Difference between ecoCOMPACT and auroCOMPACT in terms of connection
ecoCOMPACT boilers (VSC and VCC ranges) are stationary condensing boilers with an integrated domestic hot water storage tank – either a layered tank (VSC, approx. 90 l volume, equivalent to a classic storage tank with a capacity-adjusted rating of around 160 l) or a classic tank with a heating coil (VCC, 150 l volume). auroCOMPACT (VSC D) is a variant designed for combination with a solar system, where the storage tank contains an additional solar heat exchanger for connecting solar collectors. In both cases, this connection accessory set covers the same basic connections – the heating circuit, the domestic hot water circuit, and the gas connection – regardless of whether the boiler is subsequently supplemented with a solar circuit. The solar circuit itself (collectors, solar station, controls) is handled as a separate accessory beyond this set in the auroCOMPACT variant.
The set's place in the overall boiler package
In standard Vaillant commercial practice, this set is often included in an offer together with the boiler body itself and a universal control unit (for example multiMATIC 700), as it is an essential prerequisite for the functional commissioning of the boiler. When ordering a standalone boiler body without specifying a complete package, the connection accessories therefore need to be purchased separately – this is precisely the role of this set, which covers all mandatory connection and safety components in one place instead of combining several partial parts.
When purchasing, we recommend checking in advance whether the chosen boiler already includes the set in its price, or whether it needs to be added to the order separately – this is one of the most common customer questions when comparing the price of a standalone boiler body against a complete package with controls.
Frequently asked questions
Is this set necessary for every ecoCOMPACT or auroCOMPACT installation?
Yes, it is standard, and in practice always required, accessory equipment, without which the installation of a boiler with an integrated storage tank cannot be legally and safely completed, as it contains the mandatory safety equipment for both circuits as well as the gas connection.
Why does the set have two different safety valves (3 bar and 10 bar)?
The heating circuit and the domestic hot water circuit have different operating pressures in the ecoCOMPACT/auroCOMPACT design, and therefore also different requirements for the opening pressure of the safety valves – 3 bar for heating, 10 bar for the domestic hot water circuit in the integrated storage tank.
Does the set also include a connection to the chimney or flue gas outlet?
No, this set covers the connection to the heating circuit, the domestic hot water circuit, and the gas supply. The flue gas outlet (e.g. a vertical roof flue) is handled with separate accessories according to the specific layout of the building.
Can I install the set myself?
No, installation involves work on the gas supply and the safety equipment of pressurised circuits, and may only be carried out by an authorised person qualified to install gas and heating appliances.
Is this set also compatible with older ecoCOMPACT models?
The set is designed for current ecoCOMPACT and auroCOMPACT models. For older or differently designated models, we recommend checking compatibility in advance with an authorised Vaillant service centre, as connection dimensions may vary between generations.
Where does the water from the set's drain hoses go?
The drain hoses must be routed to a safe location, usually a floor drain or other suitable waste outlet, so that any water leaking from the safety valves does not endanger people or cause property damage.
How often should the set's components be checked?
We recommend performing a functional check at least once a year as part of the boiler's regular service inspection, carried out by an authorised service technician.
What is the warranty on this set?
Genuine Vaillant accessories carry a standard 24-month warranty from the date of sale or commissioning by an authorised service technician.
Can this set be purchased additionally if the boiler was installed without it?
Yes, the set can be ordered and fitted at a later date; however, given how essential it is for the boiler's safe operation, it is in practice always included in the original installation. Retrofitting requires a short shutdown of the system.
Does this set also handle automatic water top-up in the system?
The set includes a manual filling valve for topping up heating water, not an automatic filling system. Automatic filling can be added as a separate accessory depending on the needs of the specific installation.
Is this set suitable for auroCOMPACT with solar backup heating?
Yes, the set covers the connection of the heating circuit, the domestic hot water circuit, and the gas connection in the same way for both ecoCOMPACT and auroCOMPACT. The solar circuit itself (collectors, solar station, and controls) is added as a separate accessory beyond this set in the auroCOMPACT variant.
Why is this set often mentioned together with the multiMATIC 700 control unit?
Vaillant often offers this set as part of a recommended complete boiler package together with the universal multiMATIC 700 control unit, since both components are needed for the full and safe commissioning of an ecoCOMPACT or auroCOMPACT boiler. The control unit, however, handles system control, while this set handles the physical connection and safety equipment.
What if I only need part of the set, for example just the gas connection?
The set is supplied as a complete unit. If you only need to partially replace a single component (for example, a standalone safety valve), we recommend consulting an authorised Vaillant service centre, which can advise whether it is more suitable to order just that individual part or the entire set as part of a more comprehensive replacement.
