Rated 5 out of 5 by from A must have for heater removal I had to remove an old heater element that had started leaking. I wanted all the help I could get so before I even used this, so I sprayed a whole can of Crack-it Shock Release Spray on the element. Left it for 2 minutes and then used this box spanner. I can't say if the Crack-it spray helped but I really didn't want to damage the tank and have to spend hundreds of pounds replacing it. I'd read up quite a bit on removal. I would say *do not* use an extension on this products bar. With an extension, you will be turning the emersion heater slowly and risk buckling the tank. I put the box spanner on and walloped the bar with a lump hammer. I though my first hit was quite hard but it didn't budge. I hit it again quite a bit harder and bingo, the seal broke and I was able to remove by hand. The short, sharp wallop should prevent the tank deforming/buckling/twisting/splitting. I left all the water in the tank while breaking the seal as it adds a lot of weight to the tank and can also stop it from buckling when walloping the box spanner bar. There's no way you could do this with a cheap immersion spanner. It's worth spending the extra to avoid damaging the tank. One of the reviews complained about the bar being too soft and bending. Mine is 11mm diameter and walloping it with a lump hammer did not bend it. Although, I can imagine it might bend if you put an extension on. The box spanner was also a reasonably snug fit on the heater I removed. I actually replaced the heater with a plug but I would say when putting a new heater in, after cleaning up the threads and mating surface with some wire wool, you should only need to tighten up the new heater as much as you can by hand using the bar on the box spanner without an extension.

Rated 5 out of 5 by from Simple but good A nice, simple and sturdily constructed tool. Easy to use too

Rated 4 out of 5 by from Spanner Fits quite well and sturdy enough to apply a good amount of force. Not as solid as the Monument tools cast spanner but then it is the cheaper option.

Rated 5 out of 5 by from This is what you need Don't consider the cheap spanner, you need the box type. This is nice and heavy and fits like a glove. Mine needed heat and some taps with lump hammer. The spanner just bent and slipped off.
