yes its easy to swap 1 to 1 . open cover and disconnect the 3 lines L N E . but ,,

But first you need to know how the power flow into the WH from DB box.
if there is a plug point then pull of that plug cable connect. to remove power .
or if it comes direct from DB box ... then trip off the MCB . use a meter to confirm no 240V power at the WH live .

last is if you dont know how the power flow .. then trip the main RCB , then whole house no power .
do this during daylight time and keep a touch handy .
This method also good cos you test your RCB still functional or not.

A friend that work as technician for many budget hotel told me Joven is the most durable among all brands

Better than other brand alpha pana etc

Thanks for the tips

My house using Centon, it's stated rcd on the water heater and it's different when you off the water heater switch outside the toilet, it will make a trip sound, like some physical switch is turned on/off, same thing when you off the power supply.

If olden days water heater, that use elcb won't have such sound at that volume.

I do believe it's Rcd else they won't openly market it. Btw sharp also is using Rcd as they oem from centon, maybe one day when I open the water heater, I will check see what is the sensitivity

Joven is malaysia brand.

Made in Klang,Selangor



Just look at the wiring design.

Who want to buy?

The water not hot.
Need to wait a few minutes only have hot water come out....


My houseowner want to save 30 SGD,haiz


I wonder this joven 1 year warranty can last really 1 year or not

Spend the money and get a built in heater.

If you open the both pana and joven casing, compare it's Internal components side by side. Pana seem much more robust with better internal waterproofing.

yup if u buy from senheng u add installation is 95 hehe

Especially the lne wire?
