Fit a 10mA RCD per water heater (at the DB box).
The why's are here - https://forum.lowyat.net/index.php?showtopi...ost&p=103837393

Also, for the mains RCD (whole house) use a 30mA.

Humans die above 50mA leakage current passing through the water heater.

Hence, 100mA/300mA RCDs are "close one eye" or "close two eyes" = they will kill you before they trip.

Saw this article as well and forwarded to my contractor, as I'm currently doing major reno for my place.
The electrician initially only wanted to put a 1xRCCB 100mA for whole house.
When I enquired about the water heater + solar heater, he said that it all comes with built in ELCB.

Anyhow, I've insisted he put a RCCB 10mA for each heater and 30mA for others

Thanks ceo684 and other sifus for sharing your extensive knowledge and guidelines from your many posts.

Important for those who want to do a up new DB, best ask what is included and brand - look up the many post by ceo684 and other sifus on LY)
Some might even give you RCCB 300mA! (which is wrong and extremely dangerous).
By ST guidelines, suppose to have RCCB (maximum mA)
100mA - lighting, etc,
30mA - socket
10mA - each heater

Found this very nice guide by ST which includes the examples of proper wiring layout (attached)

Firstly you need an isolator switch before the RCCB

second...the MCBs not sure how they connect to lighting an sockets. need to check..to see which circuit goes to which MCB. then only know compliant or not

Water heater's output water temperature depends on:
1. Power rating (kW) - The higher the power rating, the higher the output water temperature.
2. Water source water temperature - the colder the water source, the colder the output water temperature.
3. Water flow rate - The faster the water flow, the shorter time the water source passing thru the heating element, the colder the output water temperature.

Most common SIRM certified instant water heater power ratings are 3.6kW (PANASONIC, JOVEN, ALPHA), 3.8kW (MIDEA, TOSHIBA) to 4.2kW (CENTON). If these are not hot enough for u, u can opt for Highlands version 5kW range (CENTON, JOVEN), usually meant for colder places like Genting or Cameron. Or there are even hotter ones in the 7kW range (CENTON, BEEBEST), but for those u need higher spec 6mm cables.

In your case, if u live in KL weathers and your water heater is still not hot enough, it is usually your water flow is too fast (maybe you have external water pump like Grundfos or living in condo with powerful water pressure), or u should upgrade to an instant water heater with higher kW because your current one is not satisfactory enough for u.

RM450 for instant water heaters with DC Pump + Rainshower is impossible. The cheapest one in the market is CENTON EcoSerene Rainshower (Shopee showing RM499 only, very good reviews), with low cost, shorter rainshower;
followed by those brands that are made in China like TOSHIBA, MIDEA, HAIER (Shopee showing RM555 for TOSHIBA);
and others that are above that price that are made in Malaysia, like your PANASONIC, JOVEN, ALPHA, CENTON.

Overpriced..for that price bracket no push start.
All are the same.. electric kettles in a plastic box.

Most cost effective is the RM280 Pana Push start model.

Thanks for the advice. I decided to try Centon Serene SR711 for my guest room. It was recommended by a salesperson too.
However, for Joven, I will go for the non-rainshower type for myself. Can I have your suggestion on which model (SB11iP or SL30iP) to pick?
I need a DC inverter type with a pump. Not sure what is the difference between these 2 models

CENTON and MIDEA is using enamel-coated tank (newer and more reliable technology), while JOVEN is using stainless steel tank (old technology, more prone to leakage and more expensive).

I suggest to go with brands with enamel-coated tank since has better leak resistance and cheaper on average.
