Lavatherm 22mm Magnetic Filter & 500Ml Central Heating Inhibitor Pack from B&Q

LavaTherm

The LavaTherm Boiler Care Pack is the professional solution for protecting domestic central heating systems. This dual-action bundle integrates a high-strength magnetic filter with an NSF Approved 500 ml inhibitor to target the primary causes of system failure: galvanic corrosion, limescale buildup, and black iron oxide sludge (magnetite). Engineered to satisfy boiler manufacturer warranty requirements, this kit extends the life of critical components like heat exchangers and pumps.The LavaTherm 22mm Magnetic Filter provides robust physical defense. Built from glass-filled reinforced nylon (PA66), the housing withstands high-pressure environments common in modern heating circuits. Featuring nickel-plated brass valves, it fits standard 22mm pipework. Its high-strength magnet captures abrasive metal particles before they settle in delicate waterways. The compact design is purpose-built for tight spaces beneath combi-boilers, offering 360-degree installation flexibility for horizontal or vertical pipes.The 500 ml Central Heating Inhibitor is a high-concentration, NSF Approved formula safe for all metals, including aluminum and stainless steel. A single 500 ml bottle treats a typical 100 Litre system (approx. 10 radiators). Once added, it forms a protective barrier on metal surfaces, halting electrochemical reactions that cause rust while preventing limescale from restricting water flow.Consistent use enhances heating efficiency by maintaining a sludge-free circuit. This eliminates radiator cold spots, improves thermal transfer, and reduces utility bills. Maintenance is simplified with the included drain-off adaptor and specialized servicing tools for rapid annual cleaning. This kit is a cost-effective insurance policy against emergency plumbing repairs.
