Abstract

A method and apparatus (10) for separating magnetic and non-magnetic particles from water in a domestic central heating system is disclosed. A magnet (60) is located in the housing and the inlet and the outlet are arranged so that, in use, water flows through the apparatus in a cyclonic motion from the inlet downwardly proximate the walls of the housing, and then upwardly within the downwardly flowing water, to the outlet. Particles entrained within the water separate out by vortex separation as the water flows downwardly. Also, magnetic particles entrained within the water are collected on the magnet as the water flows upwardly. The apparatus also comprises a sleeve (30) located within the housing such that an outer circulation channel (31) is defined between the housing and the sleeve. The magnet is located within the sleeve such that an inner circulation channel (61) is defined between the sleeve and the magnet. The inlet (40) of the housing is arranged to deliver the water into the outer circulation channel, and the outlet (50) of the housing is arranged to exhaust the water from the inner circulation channel.
