Box Immersion Spanner 3.6 5 21 21
No use on rounded-corner octag This is a sturdy tool; but it was no help to me. Even after neatly removing the washer from under it; our old-style heater wouldn't shift. This 87mm-across box-spanner turned on the 82mm-across heater element, without moving it. Screwfix' instructions do not cover removal of old heater element at all; but instead skip from disconnecting wiring to cleaning the thread, and fitting a new element! I had to drill a line of holes across the head of the old heater; then carefully cut and file to split one brass shoulder and thread entirely. Then, using my 12" Stanley FatMax waterpump pliers, I could squeeze the split-line enough to unscrew the thing. The Screwfix box-spanner's cost, in both time and money was all wasted: as I had to use my other tools, and ingenuity, to get the job done. This spanner is no use on tighter old-style rounded-corner octagonal heater elements. 13 Apr 2015
Good Tool Seems very strong, handled the Emersion heater on a old style Megaflo without much bother, but had to use a strong pipe in conjunction with the Tommy bar to get a bit more torque. Turned out to be an easy job, buying the tool is a small price to pay compared to calling out a plumber. 14 Mar 2015
Very Poor Bar Which Bends! Very tight fit on immersion element but let down by the bar which bends easily and and was not rigid enough to release the element. Had to spend double again for another make from another supplier but it did the job effortlessly. 7 Mar 2015
