Central Heating Protection

Every ADEY product, and exactly when to use it

ADEY pioneered magnetic filtration and remains the UK's first-choice brand for keeping central heating clean. But the range now stretches well beyond a single filter, from the palm-sized MagnaClean Micro through to the heat-pump-specific MagnaClean HP and the professional MagnaCleanse power-flush kit. Picking the right one comes down to two things: the type of system you have and the job you need doing.

This guide walks through the whole ADEY collection at Quality Heating, explains how each product differs, and shows which application each is built for, so you can match the filter to the system with confidence.

Sludge is the number one cause of central heating breakdown, costing UK households over £700 million a year in unexpected repair bills.

The basics

Why a magnetic filter matters

As steel radiators and pipework corrode, they shed black iron oxide, known as magnetite or "sludge". Left unchecked, it collects in radiators, blocks pipework and clogs the boiler heat exchanger and pump, cutting efficiency and eventually causing failure. A magnetic system filter sits in-line and captures this debris before it can do damage.

1

Corrosion begins
Oxygen reacts with steel inside radiators and pipes, producing magnetite that circulates with the system water.

2

Debris builds up
Sludge settles in cold spots and restricts flow, so radiators heat unevenly and the boiler works harder for the same output.

3

The filter captures it
A powerful magnet pulls magnetic debris out of the water, while a fine gauze traps non-magnetic particles and biological matter.

4

Efficiency is protected
With contaminants removed at every pass, heat transfers cleanly, bills stay lower and the boiler or heat pump lasts longer.

The cost of doing nothing

Protection pays for itself

Up to 7%

Annual gas savings achievable with ADEY Best Practice water treatment, based on independent UK research.

Up to 250kg

Estimated reduction in CO₂ emissions per year on a protected system.

A clean system heats faster, holds temperature better and puts far less strain on expensive components, which is why ADEY filters carry a 10-year warranty when registered within 30 days of installation.

At a glance

The ADEY range compared

Every product below does the same core job—protecting your system—but each is engineered for a different system size, space constraint or task. Use this table to spot the differences quickly, then read on for the detail.

Product Connection Best suited to What makes it different
MagnaClean Atom Compact Space-restricted domestic boilers ADEY's most compact magnetic filter for the tightest installs
MagnaClean Micro (Black) 22mm Smaller domestic systems, limited space Ultra-compact body that still captures magnetic and non-magnetic debris
MagnaClean Professional 2 22mm / 28mm Standard domestic gas, oil and system boilers The UK's first-choice filter; removable spacer for flexible installation
MagnaClean Professional 2XP 28mm Larger domestic and light commercial systems Higher capacity, dual-action capture, bi-directional flow
MagnaClean DualXP Large bore Large domestic and commercial systems Dual-chamber design for maximum magnetic and non-magnetic filtration
MagnaClean HP 28mm / 1" Heat pumps, underfloor and low-temperature systems CycloFlow technology; captures magnetic, non-magnetic and biological debris
MagnaCleanse kit 22mm / 28mm One-off deep clean of an existing dirty system Portable power-flush kit, not a permanent filter; flush in ~2 hours

Connections and availability can vary by variant, check each product page for current specifications.

Heat Pump & Low-Temperature Protection

MagnaClean HP™

If you run, or are planning, a heat pump, this is the filter to know. Low-temperature systems run cool enough to become a breeding ground for bacterial growth, which can clog the system and quietly erode efficiency. MagnaClean HP is engineered specifically to defend against this, capturing magnetic debris, non-magnetic debris and biological contaminants in one unit.

Its unique CycloFlow™ technology drives water through both capture zones to maximise first-pass capture, while a non-blocking design keeps flow rates high even when the filter is working hard—exactly what a heat pump needs.

ADEY MagnaClean HP heat pump system filter
  • Operating temperature3°C to 95°C
  • Max working pressure6 bar
  • Max flow rate80 L/min (5m³/h)
  • Fluid capacity930 ml
  • Valve connection28mm compression
  • Warranty10 years

Deep Clean & Restore

MagnaCleanse Complete Solution Kit

A filter protects a system going forward, but an already-sludged system needs cleaning out first. That's the job of the MagnaCleanse Complete Solution Kit, ADEY's professional-grade power-flush system. It pairs the RapidFlush filter with the VibraClean agitator to shift even hardened debris, often without removing radiators.

Fast

Flushes a typical domestic system in as little as two hours, up to two-thirds quicker than standard power flushing.

Thorough

The VibraClean agitator removes more sludge in 20 seconds than 30 minutes of flushing without it.

Single-pass capture

Designed to remove virtually all suspended black iron oxide in one pass through the RapidFlush filter.

Best practice

The recommended first step before fitting a permanent filter and dosing inhibitor, in line with BS 7593.

Choosing by application

Which ADEY product for your system?

Standard gas or oil boiler

The MagnaClean Professional 2 is the default choice, the UK's best-selling filter with a flexible removable-spacer fit.

Tight or awkward space

Where the pipework is cramped, the compact MagnaClean Micro Black or MagnaClean Atom fit where larger bodies won't.

Large home or light commercial

Higher water volumes call for the high-capacity Professional 2XP or the dual-chamber DualXP.

Heat pump or underfloor

Low-temperature systems need MagnaClean HP, with dedicated capture for biological growth as well as sludge.

Existing dirty system

Power flush first with the MagnaCleanse kit, then fit a permanent filter and dose inhibitor.

Ongoing chemical protection

Top up with a chemical pack such as the Professional 2 Chemical Pack or Micro 2 Chemical Pack.
