The Vaillant Advance Boiler Protection Kit is a comprehensive maintenance and protection solution designed to help prolong the life of your Vaillant boiler and central heating system. It includes components that work together to protect against corrosion, debris build-up, and operational inefficiencies, ensuring smoother performance and fewer service issues over time.

What It Does

This protection kit typically combines:

A magnetic or scale/dirt filter that captures and retains sludge, rust, and magnetic debris circulating in the heating system. By removing these particles before they reach key components such as the boiler heat exchanger and pump, the filter helps prevent blockages, cold spots on radiators, and reduced heat transfer.

A chemical corrosion inhibitor formulated to be dosed into the system water. This inhibitor helps form a protective layer on metal surfaces inside the boiler, radiators, and pipework, reducing the effects of corrosion and helping maintain flow and efficiency.

Potentially additional items such as a system cleaner or a sealing additive depending on the specific kit version supplied, to help prepare the system before inhibitor dosing or address minor leaks.

Together, these products protect internal components, support efficient heat transfer, and reduce the risk of faults or breakdowns associated with sludge, debris, and corrosion.

Compatibility

The Vaillant Advance Boiler Protection Kit is intended for use with Vaillant boilers and central heating systems, including combi, system, and conventional boiler configurations. It’s suitable for domestic installations where maintaining system cleanliness and corrosion protection is a priority.

Key Benefits

Using a protection kit helps:

Improve circulation and heat distribution throughout radiators and pipework.
Reduce risk of boiler and component faults caused by debris and corrosion.
Enhance heat transfer efficiency, which can help lower fuel use and improve comfort.
Extend the service life of the boiler and heating components.
Lower the frequency of servicing and potential emergency repairs.

Ideal Applications

This kit is ideal for:

New central heating system commissioning or after boiler upgrades.
Existing systems showing signs of sludge or corrosion.
Routine maintenance regimes to ensure ongoing protection and efficiency.
Homes where minimising service costs and maximising boiler life are priorities.

How to Use

The protection products are typically introduced into the heating system via the filling loop or a magnetic filter connection during servicing or commissioning. The cleaner, if included, is used first and the system flushed afterward. Then the corrosion inhibitor is dosed to the required level based on system volume. Filters are installed on the flow or return as recommended by Vaillant or a qualified engineer.

For best results, installation and dosing should be carried out by a Gas Safe-registered engineer or qualified heating professional to ensure correct application and optimum protection.
