It is the showering water and your ground feet.

i on it and heat up the water for a while. then i switch off and take a shower. How dangerous can it be?
maybe I need to worry about falling off the bed as well.

the problem starts at the inside. Cold water runs through a narrow pipe with an electric heating element heating up
this pipe giving you that instant heated water. So imagine if the heating element is leaking electricity to the water.....

btw because the water is going thru narrow pipes, the water flow rate is very low. some have buildin pumps which increases the water
pressure but you still get a rather poor flow rate. I was quite surprised when some of these instant heaters even came out with rain shower type of head.

how bout water heater tank, does it has ELCB ?

so if faster water flow rate can prevent electrocution? like external water pump?

what if stand on rubber mat in shower and use water pump?

i suppose best to use bath tub

bro, flow rate is another topic. nothing to do with electrocution
sorry if i confused you

IMPORTANT
· All plumbing works must be completed and heater tank filled with water before proceeding to electrical connections. This will prevent any damage to the appliance.
· Ensure that the electrical supply is single-phase at 220 to 240 Va.c.
· This appliance must be permanently earthed. The use of Plug & Socket is not recommended.
· It is recommended to install an approved current operated type Earth Leakage Circuit Breaker (ELCB) or Residual Current Circuit Breaker (RCCB) of 10mA sensitivity and higher than rated current (Refer to table).
· It is recommended to install an approved type Miniature Circuit Breaker (MCB) or Molded Case Circuit Breaker (MCCB) of higher than appliance rated current (Refer to table).
· Ensure that the wiring can supply the necessary amperage (Refer to table).
· This appliance must be permanently connected to the electrical supply through a Double Pole Linked Switch above rated current (Refer to table) and having contact separation of at least 3mm in all poles incorporated in the fixed wiring. The switch must be out of reach from user in the bathroom.
· Do not share the electrical supply with other appliances.

Me just replaced my Panasonic WH (10years old)... recently... to Joven WH with rain shower... I didnt buy those with pump coz I have redo the piping so that the WH is using direct water instead. Good news is good pressure... bad news is no water supply no hot water la...

The main thing is brand... most of the time I see those case happened is when they use dunno what type of china made brands... better to use a branded WH...

The water is the electrical transfer medium. The electrucute doesn't neccassary coming from the shower that you use. It can come from anybody that using the water.

I m not sure about this. Weikee is using storage tank. Maybe he can answer you. Additional elcb for safety perhaps?

Panasonic is more reliable. Why choose joven? Branded?

it doesnt have its own but your house already has one, just make sure it has the required ratings



yup just follow the instructions that you posted

even if heater element leaks electricity, the water can't conduct electricity as it breaks up into drops as it comes out of the showerhead and won't create a circuit

and if all external parts are plastic/non-conductive then should be ok

'dying' to know what is the brand of the water heater!!

no worry on all instant water sold at reputable shops........to avoid this incidence...........


1) make sure you hire a good electrician and also confirm with your own eyes that he join the EARTH WIRE correctly at the heater.

2) If your home or rented unit is more than 10 years of age............pls change the electrical fuse at the fuse box.........esp. the main fuse otherwise in case of emergency the main fuse will not trip !
Better still.......change all fuses there......cost RM5.00 per unit......main fuse cost more............the expensive part will be the electrician's labour charges...........

This will prevent unnecessary accidents........

All storage heater piping will be earth. Make sure house earth cable are working. I earth all my ss piping.

Even solar can be dangerous if electric leak. Imagine a live wires touches the steel / copper pipe. These can happen when rats bit the cables and it touches the pipes.

You forget your hand holding the shower head which inside is a continue water flowing. While your hand and body is wet.

And the water is not really breakup as what you see in the rain. Don't forget, the flow rate is higher than the rain outside. This is not I just talk kok. I did use a fast speed camera to record the water flowing from the shower.

Your curiosity is haunting you.

Storage tank have earth wires.

The key is to have your house earth wire working. Without Earth is without protection.

Haha... like that also can. I got no comment already.
