Also make sure that the storage water heater is being installed with:
a. 2 Isolation Barriers (at water inlet and outlet) - to prevent electrocution
b. Pressure Relief Valve (at water inlet) - to prevent storage tank from being over-pressured (which might cause it to rupture / leak), and to facilitate water drainage during servicing

If I am not mistaken, this will be a compulsory requirement set by SIRIM and Suruhanjaya Tenaga for all SIRIM-approved brands to be pre-installed with these 2 items soon.

By far, storage water heaters market leaders like CENTON and JOVEN already followed this ruling. But just double check during your installation and make sure these 2 items are being fitted, just in case the brand u have bought doesn't have them.

This Sharp model WHN-115, which I
bought from Jintex Credit in
Seapark here is reliable .

Nonpump, cost $ 195.

Bought in December 2018, when my
brother shifted out, dismantled his
Joven, left nothing behind for me.
Even took the water pail away.

Quite hot. Most times I set the temperature knob at between
9 to 10 o'clock when bathing.

At that setting, I calculated the
power consumption is between
975 to 1,350 watts. Good enough for me.

On a hot afternoon, turn to the
lowest, 8 o'clock, 600 watts, or shut
off altogether.

Every one o'clock step will burn
375 watts.

If you turn it to between one to
two o'clock like most people do,
it would be burning 2,400 to 2,800 watts, worse than an electric kettle.

They have a pump model, over $ 400.

Initially I was trying to save money
and buy Midea, $ 130 to 160, but
luckily I read the reviews - " Hopeless. Lukewarm at maximum setting. "

The only drawback is, the water- sensitive switch isn't good enough.
It requires a minimum pressure of 3 PSI to trip it, or 2 liters a minute.

Panasonic's one is more sensitive -
just 1.8 PSI, or 1.2 liters a minute.


Seems they have two models with
pump, WHP-315 and -219.

This is just $ 375.

All also will recommend 4mm as per ST guidelines. 2.5mm proper cable can still use lah if its 3kW class (divide the 3800W by 230V to get amps 16.52 A). Still within 21A max current capacity of quality 2.5mm² cable. If substandard cable then another story lah.

Quality cable meaning SIRIM approved MS2112:3 compliant cable for the ones concealed in the wall.
Quality cables will print the spec and certified to MS standard blablabla not just to show off, but its a requirement as PVC cables are controlled items -see https://www.st.gov.my/en/contents/files/dow...ble_testing.pdf. Those that never print are suspicious.

Fake certification on cable also a problem here in Bolehland - https://www.sirim-qas.com.my/forgery-on-license-no-pc000218/

You should NOT use a 4.8kW class heater with 2.5mm² cable as it is running at redline for 2.5mm² cable.
