Jesus, that's low well done. I put mine in as far down as I could reach, but I leaves a cold spot that's about a third of the tank.

[Smurf]

Two things that would bother me are as follows:

1. Length of the element as seems very long and looks very close to the bottom and centre baffle of the tank.

2.These things are designed for static water heating not driving about so I would keep an eye on it especially the end of it as could melt your tank. Not to mention melt yer balls too.

Going by the pic inside the tank it already looks like it's on the p. lol

I know Nathan cant get his head around this but there is also something out with his heating times, for 500 litres
the minimum time needed for 42degrees would be 12.2 hours with a 2kw heater.
So either his tds meter is out or more worryingly his heater could be running higher than 2kw which may not be suitable
for his electrics.

I've had a 27" element in my tanks for 6/7 years with no issues (500 ltr Wydale currently). The mechanical flange makes a very solid fixing for the element.

Theres a good distance still from the base of the tank to the element rods and the baffle part of the tank angles up like a roof top, so there is plenty of space above the element as well. In addition to obvious surround of water. Little chance of actually melting the tank especially whilst static over night.
By time the water level drops for the balls to be close to the element, theres no heatvin element to damage my already melted balls

With the mechanical flange you don't need to reach inside with your arm or a tool. Just lower it on a wire and connect from the outside.

I know Nathan cant get his head around this but there is also something out with his heating times, for 500 litres
the minimum time needed for 42degrees would be 12.2 hours with a 2kw heater.
So either his tds meter is out or more worryingly his heater could be running higher than 2kw which may not be suitable
for his electrics.

Depends what temp the water is when it goes in the tank. If it goes in at 12 that's only a 30 degree increase.

Don't forget he's reading from the top of the tank. The whole 500 might not be as warm.

Your right, I didn't allow for that, Doh.

Doh, silly me! My element is virtually at the bottom of my tank. So what your saying is i cant get my head round how low the temp is at the top of my tank because its going to be even higher near my element. 

How come theres critics on here telling me that i dont know the actual results im looking at, feeling and reading with a tds temp stick. I must be a fool. Best stick a ticking time bomb in van and use a gas heater instead

Get a soup ladel, reach down to the bottom of your tank pull out the water and test the temp

Calm down mate, heat rises including heat in water so even though your element is at the bottom of the tank the water will always be hotter at the top.

There you go Nathan this might explain it,

Can  you use a plug in timer with the immersion?

[Dave Willis]

Yep

Perhaps i dont waffle enough in the right direction. As in yes i know about thermal rise within water etc etc, though the video was a nice touch. However, the waffle i miss out is how i shake the water up so it can mix before i take any readings, so its an accurate reading (well as far as a china made tds stick is concerned).
Also as can see in the picture my mighty girth yellow hose on my pump that feeds my trolley. It gives the same reading.
As far as the calculations for heat transfer through liquids is concerned, i pointed out before it doesnt take into account additional variables.

the only reading ive not taken is at the brush end, but when i run it to get the hot water flowing through, you can clearly see its not cold or tepid as it was with the resstricted fish heaters.  For me, this works and im hapoy with the results. Just wanted to share what works for me as someone else may find it beneficial as i have through people sharing their experiences on this forum.

Well done Nathan. Popular topic. You have a big one ha ha
I only have a 14 inch 2kw heatrod
Setting 3 reaches about the same temp but small tank.
I put in an aquarium aerator pump, small and only cost a few quid but it does seem to move the water around.

Yes, I use this one (2kw)  http://www.toolstation.com/shop/Electrical/d190/Plug-in+Timers/sd3182/Plug-in+Timer/p22617

Great posts Nathan. Exactly what I did but didn't take pics 

I use mine solely to stop pipework, pumps and reels freezing in the van
