Stainless Boiler - 3kW Immersion elements

I had seen the industrial elements on a dairy site, just over £40 for an element, I dont know if that is with a stainless boss rather than brass, also listed were rod stats that went op to 110degC
I am considering using an imersion element for my boiler but I plan on using a copper water cyl then the threaded flange can be silver soldered on and if I so wished I could fabricate an enclosure to soft solder to the wall of the cyl which would take a gland and have a gasketed lid.

It takes as few as 80 milli amps to kill you dead, a car battery can stop your heart and kill you at 12v!Graham wrote:You did say amps - I used volts because it is them that hurt. Your car-battery can supply 200 Amps, but it won't kill you (unless you drink the acid).
A few milliamps is enough to kill if there is enough voltage there to produce it.
The voltage is irrelavant (yes I know ohms law)
50k volt tasers incapacitate because amps are so small

Hi all.
I have just found this site and have not stopped reading / learning for a few days its such a goldmine of information, please excuse and noobie stupidity as I have never used a forum before and therefore might breach some rule / etiquette somewhere along the way.
My HLT split and I decided to replace and upscale my brewery as most of it is reaching the end of its life anyway and that lead to a Google search and this forum, reading this thread about immersion heater elements in boilers made me think about a wax melter I made for my daughters body camouflage business.
This wax melter is akin to a HLT IE it contains water held at a constant temperature and from here the link to brewing was obvious I used a legally obtained beer barrel with a 2.5KW washing machine element linked to a pid for this project and it has seen almost constant use for the last two years with no problem.
The element I chose has a rubber compression fitting as an integral part so fitting was easy cut an oblong shaped hole in the barrel push the element through and tighten the nut.
The electrical connections are made with spade connectors, and the tube where the thermostat from the washing machine should live I filled with heat transmission paste and pushed the pt100 sensor for the pid in.
For a cover I bought two of the proper parts for the element adapted them to fit together and glued them, job done.
Quite how this would adapt to a boiler I am not sure, I doubt if a plastic container would be strong enough for the compression fitting for starters, I have Emailed the manufacturer of the element to see if it is food safe and await their reply.
There are bound to be other issues with this idea but it is another option with prices for these running from £15 to £stupid.
Sorry if was long winded.

I eventually found a system where I got the boa strap gripped tight on the boss and then tightened using the spanner on the outside. Given the shape of my boiler I was actually head down, half inside the boiler holding the boa whilst turning the spanner with my foot.johnmac wrote:I'm having great difficulty tightening the element against the curvature of the pot.
Would an oil filter chain or stilsons be any better than the Baby Boa strap wrench I'm using?
Or otherwise, is there a (food grade) sealant which I could use?
In my experience silicone sealant won't work. JB weld might but if the element dies you may have issues getting it out again.
