Immersion Heater Element problems

[Pete999]

Even if on continuously 3 weeks seems very quick to go wrong ! !

Well you may be right mate but if the water is very hard 3 weeks on continuously it's taking a bashing just a thought really

Why should the heater be on continuously, unless they leave the tap running? Surely it'll just be on until up to temperature, at which point the thermostat will switch it off.

I was just trying to say a tank that size with a 3KW heater, washing horses would be on more time than its off a lot more usage than a domestic environment, just a thought that was all

so pete--(with respect) a 3kw immersion will fail if its over-worked/on all the time?
noone washes horses at night do they-- therefore the stat will cut the power?
imo no anode and/ or mixed piping /electrosis splitting the element casing
seen it a few times

May I suggest that you contact manufacturer of the elements for their thoughts .
Titanium heaters are sometimes specified for types of acid and " other nasties "
so am puzzled the same as op , best of luck in overcoming problem .
Ps , I have had problems with water starvation causing heaters to fail , it should not
happen in theory but worth checking ! Ken .

The culprit sounds like the heavy coating of stuff building up on the element, if it is as thick as the OP describes. That can cause rapid overheating and will damage a titanium element as much as an inconel one.

Wrong kind of water, it seems.

 

[ayjay]

then why don.t the manefacturer state this on the instuctions ? eg " not for use with hard water or it will only last for a short time"?
many places have hard water there must be zillions of immersions that only last 3 weeks!

If it’s indirect there must be a header tank. You can get dysenteric water treatment to add in to the header.

With it being an indirect cylinder there is a way around the problem. Send me a PM with your e-mail address and I’ll send a drawing. Sorry I won’t post it in open forum.

tony you saw my question! hallajuja--- or one of them the indirect cylinder /calonifier
what about an anode or lack of

 

[Knobhead]

Absolutely nothing to do with chemical or galvanic treatment. Added to which it’s reasonably cheap and maintenance free.

This is why I asked the OP to contact me directly. I won’t put it in open forum. A good plumber can make the bits needed, a good electrician will get it to work.
