Vaillant Advance Boiler Protection Kit 22mm | 10035819 | Magnetic Filter

Description

The Vaillant Advance Boiler Protection Kit (MPN 10035819) is a 22mm magnetic system filter engineered specifically for the ecoFIT and ecoTEC boiler ranges, up to and including 35kW models. It combines a magnetised filtration chamber with an 800-micron stainless steel mesh to strip both magnetic and non-magnetic debris — magnetite, sludge and flux residue — from the central heating circuit before it can reach and damage the heat exchanger.

Vaillant's own engineering places the filter's magnetic field across a wider capture region than a conventional single-point magnet, maintaining an average filtration efficiency above 80% even once the magnet is fully loaded with debris. Its horizontal fitting profile lets it sit discreetly on the pipework close to the base of the boiler, and a 22mm isolation valve is supplied for quick, low-drainage servicing.

Extended warranty is model-specific. Vaillant's 10-year Boiler Protection Kit guarantee applies when the filter is fitted with an eligible ecoTEC plus or ecoTEC exclusive with Green iQ boiler and registered on Vaillant Advance. This particular Advance Boiler Protection Kit (10035819) is designed to complement the wider ecoFIT and ecoTEC range up to 35kW — always confirm current warranty eligibility for your specific boiler model with Vaillant before relying on it for warranty purposes.

Sourcing note: Vaillant's own technical data sheet for this Advance Boiler Protection Kit does not publish a specific magnet gauss rating — it describes an "advanced magnetising process" that maintains filtration efficiency across a wider region even when full. Some third-party retail listings quote a "12,000-gauss" figure; this is not confirmed on the manufacturer's published data sheet, so it has been left out of the specification table below in favour of verified figures only.

Horizontal Fitting

Designed to be sited horizontally close to the base of the boiler, giving a discreet, space-saving fit in tight pipework runs where a vertical filter won't clear.

Dual-Stage Filtration

An advanced magnetising process captures magnetite, paired with an 800-micron stainless steel mesh that blocks non-magnetic sludge and debris from reaching the heat exchanger.

Quick Servicing

Easy to dismantle for cleaning, with a removable magnet shield and a standard ¾" drain connection that also doubles as a chemical dosing point.

High-Quality Brass Body

A superior brass construction built for long service life, with a swivel drain head sealed on an O-ring for leak-free rotation during maintenance.

Glycol Compatible

Works with both plain water and water/glycol mixes, making it suitable for systems in cold-prone locations where freeze protection has been added.

Flexible Orientation

Vaillant lists limitless installation orientations, making the filter suitable for boilers sited in cupboards, lofts or utility spaces of varying layouts.

Which boilers is this filter suitable for?

This 22mm Advance Boiler Protection Kit is designed to complement Vaillant's ecoFIT and ecoTEC ranges up to 35kW output, including the ecoTEC Sustain range. For non-Vaillant boilers, check the manufacturer's own filter recommendations, as fitting a filter from another brand may not carry the same warranty benefit.

Does fitting this filter extend my boiler's warranty?

Vaillant's 10-year Boiler Protection Kit guarantee applies specifically when the filter is installed with an eligible ecoTEC plus or ecoTEC exclusive with Green iQ boiler and registered on Vaillant Advance. Warranty terms and eligible models can change, so always confirm current eligibility for your specific boiler with Vaillant or your installer before installation.

Can this filter be fitted in any orientation?

Yes. Unlike some vertical-only inline filters, this kit is specifically designed for horizontal fitting close to the base of the boiler, and Vaillant states it supports a wide range of installation orientations to suit tight or unusual pipework layouts.

How is the filter cleaned during a service?

The isolation valve allows the system to be drained down at the filter without draining the whole heating system. The magnet shield can then be removed to release captured magnetite, and the ¾" drain point can be used to flush out remaining debris.

Is this the same as the standard Vaillant Boiler Protection Kit?

No. This is the Advance Boiler Protection Kit (10035819), a distinct product from Vaillant's standard 22mm/28mm Boiler Protection Kit range. Both are magnetic filters, but they differ in dimensions, fitting orientation and included components — always order by MPN to ensure you receive the correct kit for your installation.
