Looks like you have dissimilar metal galvanic corrosion, copper/galvanised steel - the galvanised fittings will corrode preferentially.

1st tank or 2nd tank that you referring?


both tanks
installation done by the joven technician...

thanks ..

Something like this? https://www.centralvahomeinspections.com/wa...vanic-corrosion

means got electricity leakage but not enough to kill you yet
so best to replace it and junk the old one (unless competently restored but usually not cost effective to repair)

yes ..very lucky n lucky ...
yes ..planing to replace the tank ..

now new model come with isolation barrier..isnt can prevent electricity leakage ?

How old is you tank?

No I’m worried. Should I proceed with buying joven storage heater tank or should I look for other brand?

about 6 years old ...heating element changed 1 time b4...

or you can try solar heater ?

That bad the quality?

Solar isn’t an option. Out of budget. I’m going with storage but haven’t decided on which brand to use.

some people use for many years without problem ...

why not instant water heater ?

It should be isolated from the design (i.e. non conductive hose/plastic part for storage WH).

Electricity leakage best prevented by installing a 10mA RCD for the WH circuit.

Example in https://forum.lowyat.net/index.php?showtopi...post&p=98013150 (the ABB one)

What this 10mA RCD do is like a very detailed accountant, whatever current in must balance current return out.
If current kena songlap more than acceptable value of 10mA, shut down whole thing because songlap means the current is leaking somewhere (typically thru the poor fella taking bath). Little bit of leakage at 10mA or so will not kill a person but it will trigger the 10mA RCD to trip. You should get one from a reputable brand (ABB Hager Schneider).

Purely because of aesthetic reason.

Instant water heater looks out of place in the bathroom.

yes...the developer didnt install the rcd initiall...the wireman also didnt triggered about rcd...
now change new tank need to add 10mA rcd...
to prevent same incident happened again ...

so the only way is storage tank heater...
