Rated 5 out of 5Â by Madasafish Handles corroded joints well
I replaced a 40 year old immersion heater at the weekend - the thermostat was in Fahrenheit !, I read about how to do the job and with limited space bought this.
What a job! Heated the joint after removing the water, froze the joint - it would not budge. Added an extension to the bar - which started to bend!.
Eventually got my son to lie on his back bracing the cylinder with his feet so it would not move at all . I then used the extension (a hollow car jack handle which fitted over it) and applied all the force I could. It suddenly moved very slowly for one full turn and then came away easily.
So it works well in confined spaces and tolerates a large amount of force. Just the job.
(The bent handle was straightened in a vice)

Rated 4 out of 5Â by steve1951 pretty good tool
Fitted well - I have tried the flat spanners before and they do not work and you have to cut away a lot of the tank insulation. The tommy bar is not really long enough - we are in a hard water area and the old heater had been there 20+ years. But using a long pair of heavy-duty grips to hold the box spanner got it moving. I read that it is best to leave the water in the tank while trying to get the first movement on the spanner - water adds to structural strength of tank and reduces risk of damaging it - of course drain before taking it right out!

Simple tool - does the job well.
Good value even if you only use it the once!

Rated 5 out of 5Â by bugbug great immersion box spanner
great box spanner , the length of it keeps it away from fouling on pipe work that might be in the way and the tommy bar gives good leverage for removal and refitting immersions
