you only lived once. And since you have known of this danger, the ball is in your hand.

Is not that bad. As long get proper brand, and good installer.

BTW another fault point many did not look at. The water pump also risk electric leakage. And that will cause electrocution too. So no water pump? Solar users also use pump.

u mean the water heater in a drum installed under the roof top?

I doubt the risk is higher since there's a heater element heating the water only, wiring not in the water. The shower type has greater risk because 1) Many have been electrocuted ( have stats and reported news) 2) The outflow of the water from the shower handle carries electricity directly to the person because he/she was holding it.

But according to me gas heater is much cheaper...Anyways can you please tell me where you from??

Malaysian.

For running cost, gas is cheaper. But installation cost is higher. You need gas copper pipe, piping and backyard space for a heater. Than copper pipe for hot water to run up to the bathroom. And Wiring to the heater. All the house at here don't have such facility. That can cost thousand for the installation.

While all the house is come with the instant heater wiring and piping ready. It just take about 1hr to finish the installation. That is why it popular here.

Gas heater is price in between storage and solar. Is more expensive than storage but cheaper than solar. All three still need copper piping.

Nowadays, DB come with RCCB mostly, so when it senses imbalance current between live and neutral, (aka got leak), it trips.
And it is not rely earth wire to operate, so it eliminates the risk of earth faulty.

Storage tank can explode!!!

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.

so what your advise can give?

The heater comes with safety devices. Frequent maintenance is the answer.

From a web site:

What Causes Water Heater Explosions?

There are two common ways a water heater can create a fire/explosion and become a dangerous bomb in your Atlanta-area home.

Gas leak – If gas is leaking in or around your water heater, the small ignition flame can ignite the gas, causing a catastrophic explosion.
Water pressure – As water is heated, pressure builds inside the tank. Normally, your water heater shuts off or releases the built-up pressure through a safety valve. However if these safety mechanisms fail, the pressure can mount until the tank eventually gives way.

For instant water heater just buy a RCD adaptor, cheap and safe solution.



Choose 30mA. Never choose more than 100mA. This means a leak or imbalance of 100mA will cut off the circuit or flow of current. 100mA wont kill you.

With this RCD adaptor you have triple protection:

1. Your house main RCD
2. Your heater ELCB
3. This RCD adaptor

Like the ELCB of your heater and your home RCD, you can test the adaptor any time if it is working fine.

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.

can suggest which one suitable for storage?

The wall mounting type. Not the adapter type. But more importantly test the safety valves regularly.

+1 .. ya I suspect this is what happen exactly to that couple.. earthing copper got stolen by some stupid madafaka..

Thanks your advise. That means each time when go bathroom press it before take bath right?

Where can we get this?

I found out this don't know suitable or not. But price not cheap.
