Storage tank only "explode"
if
1. Air vent and safety valve or pressure relief valve failed,
2. Heating cut off function fail
3. Users do not turn off the heater for prolonged time, aka steam built up causing rise in pressure.

So a good practice, only turn on when need to use, and switch off after use, is first step eliminate the risk of explosion. As you needs 1,2,3 together to cause an explosion.

I think the next question that comes here is that, can we put in a second safety trigger point? should the one at the Waterheater unit fails... another device or sorts will auto trigger power disconnect upon detection of short circuit.

RCCB in the DB should able to detect it and trip, as leaking or short circuit will cause an imbalance between live and neutral wire.

What a load of BS.

In Australia Every home (about 10 million) has a hot water storage heater (gas or electric powered) they are left on all the time 24/7 365 (because they are insulated and super efficient, 2-3 times lower operating cost then Malaysian system of instant water heater).

Out of those 10 million units, how many Exloped during last 10 yrs ZERO!

Safety valves never fail, they are designed to be failsafe, ie if it stops working it will release the pressure.
If heating function never fails to cut off. Again it is design to be failsafe.
It doesn't mater if you don't turn it off, they are designed to be left on continuously. Steam does not buildup casueing rise in pressure.


How do I know this? I am an Engineer and I once worked for a company that manufacturers water heater tanks.

The present fear of using water heater gave a new thought about the safety feature after the japanese couple were electrocuted. Is the water heater tank above the roof top or the wall mounted type is safe to use? Do they need periodical maintenance or checking by professionals?  Lets dicuss.

How many people in Malaysia use water heater (instant or tank system)? about 25million!

How many people have died in last 10 yrs from water heater fault? about 4!

Not its not confirmed that the casue of all 4 was faulty water heater, its only suspected.

So your chance of dying from water heater fault ? about 4/25,000,000, or 0.00000016.

TO put that into terms that has some meaning, the average person (assuming they use the heater once per day) would have to live till they were about 17,123 YEARS old before they died from water heater fault!. basically its never going to happen!


STOP BEING PARANOID!

Paranoid one may say, what if I am one of the 4... laugh.gif

After few weeks or month, people will forget about the issue.
Very normal to see such public reaction whenever there is such news time.

So this topic after few week, less traffic already. tongue.gif

This will look neat. Come with fuse as RCD will not trip when there is a overload of current. The fuse is a overload safety point.

You can use this as a switch. Press the reset (on) as you go into the bathroom taking shower. Out of bathroom finished showering press the test button(off). In a way you are testing it every time you come out of your shower, and will never forget to test.

wow awesome, would be great if someone can let us know where to buy this thing... I will go look around for it next week.

BTW, to those who says I am paranoid... just think, is RM 50 spent on a protection device worth your life?... my humble thoughts.

There is a difference of awareness and paranoid on something. smile.gif

Awareness:
One should ask how or why it happened.
Find out the reason is important to raise the awareness to prevent it to happen.
Understand how it function etc.

Paranoid:
Water heater can electrocute people, avoid this or that.

Fear of being electrocuted by water heater is sign of paranoid.
As if water heater carry high risk of electrocuting people with ease, then this product should not be allowed to be sold in the first place already.

Fear of electrocute by water heater is as same as fear of electrocute by any electrical device.

We know speeding is dangerous people still drive like f1 driver. Everyone know tires need to change when reach certain level but some drive until tyres botak.

I read many people asking where can I buy cheapest instant heater, who can give cheapest installation price. You think they care about safety? The priority for them is saving money.

Any type of water heater be it solar, gas, insrant we install will sure have some sorts of danger. Get proper installer and don't skim on quality of work.
