We have used these over and over. Excellent tool for the van we have had all other types of immersion heater key and have failed. This is the only key to use.

I prefer this unit to the others as I keep loosing the metal rod you to thread through on the others. It’s handy to have it all as one piece. Again excellent build quality you come to expect from this manufacturer. However sometimes even with these immersion tools they are hard to remove. However a little bit of heat applied soon loosens up any old jointing compound. Don’t force it, just warm it. Obviously with the tank drained and electrics disconnected.

As always with monuments tools you can rely on them to do the job had mine for a number of years now and you have more chance of losing them then wearing out

Great price. needed for a single job. The spanner fitted onto the immersion perfectly. The one piece design meant i wasn't hunting for a separate bar, in the mystery tool bag!

Oh my god this is good. Just get one, you won’t regret it if you want to loosen or tighten an immersion heater. The spanner will take it even if the immersion heater boss doesn’t.

I can't even count the amount of times this has been used. Nice solid spanner that you can grip and tap with a hammer. Another great product by monument.

Another must have, I’m definitely a fan boy, I didn’t even need a new immersion spanner. But this was so cheap that I couldn’t resist. Perfect tool, works, doesn’t slip, it can take a whack from a hammer. 10/10

This is the one and only Immersion heater spanner you will ever need. Good thing there is no tommy bar to lose and you can give the the handle a good tap with the hammer and nothing will happen. If you need more leverage just cut a scaffold pole to size and slot over the cast iron handle to make it longer.

I have this in my tool box but I couldn't get on with it and converted back to my original, the handle is nice and bulky for a good grip bit sometimes old immersions are too tight and need a bit of leverage, I usually stick some 28mm to the end of it, which I couldn't do with this one. Maybe I should just get down the gym?

I have been using this spanner for years it is very strong you can even hit the handle with a hammer to crack the thread to stubberen jobs. I would even consider buying another one just in case they. Stopped making them.
