An immersion heater for a water cylinder or water tank comprises a base section 2 having heating elements 7, a thermostat, and thermostat pocket (6, figure 3), a detachable middle section 3 connected to a power supply, thermostat sleeve and an electrical inspection chamber, and a removable cover section 24 having a thermostat reset button and securing fixings, where detaching the middle from the base disconnects the mains power supply to the immersion. The base may comprise an upper section having a rod thermostat and plug pins, and a lower section comprising heating elements and a rod thermostat pocket. The heating element may comprise single, dual, or multiple element rods. The connection means in the middle section may comprise hollow connection points receiving the plug pins. When the middle is detached from the base, the earth pin may be the last to disengage and closure means on the hollow connection points may close to prevent access to the power supply. The cover 24 may comprise a large cover section covering the supply connections and a small cover section 5 covering the thermostat and an over cut out reset button, the small cover section allowing safe inspection of the thermostat. |
