HELP, we have a Quick Nautic Boiler BX 40 Liter water heater with a dodgy heating element.

We can’t seem to find the correct or any tool to remove the defunct heating element. It’s in a tricky position, and don’t want to remove the hole boiler.

Any suggestions.

From memory Quick normally have 1 1/2" BSP elements rather than the usual size so a standard immersion spanner will be too big. Also they have an odd thermostat with spade terminals that plug into the element which can appear to be part of the immersion element but just pulls off. Bainbridge marine do parts for them. If you buy a new element then it will be fairly easy to source an apropriate box spanner. They do three types of BX, Round, square and oblong but I think they all use the same elements & thermostats.

You can get compatible spares from Penguin Engineering http://www.penguineng.com/calorifiers.html the chap who runs it is very helpful.

Hi,

I have removed the thermostat.

I can’t get proper access, but the nut looks bigger than 1 1/2".

I will either have to beat it off, or remove the blasted boiler.

Thanks for the reply

Sorry if I confused, the 1 1/2" BSP is the thread size not the spanner size.

That will be one designed for a 2 1/2" BSP immersion and is likely to be too large. Like I said buy the new element, measure the A/F and buy a box spanner.

The one on my Quick boiler is 2¼" across the flats, see my earlier thread.

By the way, what is a "hole boiler"

The quick nautic boilers have a smaller thread and nut than the standard household immersion element. We struggled to remove ours until we got the correct fitting tool as they are in super tight.
The online shop www.yachtboatparts.com have the 1200w and the 500w and the 800w available and loan the necessary tool out when you buy the element from them which helped us out. We also replaced the thermostat as this was also as old as the element and has been switching on and off for many years whilst we live mainly on-board nowadays.

I have the a Quick Nautic B3 40 litre boiler and think that this probably very similar to the BX.

Spent a couple of days in Spain a few years ago trying to get a new element and also removal tool. Finally tracked down an element but every single place I visited had never heard of a box spanner or knew of any similar tool. I had pictures on tablet of various tools. I was told repeatedly that nobody used these things in Spain.

I could probably buy the correct tool somewhere and think I've seen it online but not even worth me considering now.

No idea it that was true but finally decided domestic elements were probably not recessed and marine guys just used a variety of bodges.

Finally solved it by putting large mole grips in at 90 degrees to end of boiler. They just managed to grip the flats and I used a small screwdriver through the jaws for a bit of leverage. Virtually no room so I had to fiddle around to get correct position where screwdriver would move it a tiny bit. Repeated the fiddling around to re-attach and move again.

I now have the knack and remove the element annually for examination and clean up in acetic acid to get rid of deposits. Correct size of mole grips should do it, I'll try to find a picture of type I'm talking about (not ones with long thin jaws).

I bought spare elements in UK from Penguin, great service and good price. I think I paid about £35 per 1200W element. Spanish chandlers usually wanted about £80-90+ (if they had them). Online suppliers usually seemed to be around £70.
