I am using Joven 880P and must say that it is the most disappointing water heater I have ever used. Extremely noisy and cold.

is that with power point? mine is rm60 or rm80 if not mistaken but already got power point

ic, that power point is conceal or pvc?
last time mine in apt fix 2(2.5mm wires) wh point and 4(4mm) aircond point non conceal/used pvc cover my wireman charge me lumpsum rm550 but this is early 2009 la. yes somtimes wireman will install for free, but piping kena provide sendiri lo.

4mm2, that can power over 30Amps of equipment.

2hp don't drain to much current. The number you got is cooling capacity. Not current. 2HP should be less than 2Kw. Please check the current or power input. Is about 10 amp the most.

Depend the length, and also if its expose or conceal. Usually conceal will be less current cause less cooling. But that number is about right. Can still stress a bit more if length are not too long and expose.

u scroll down the spec page, u'll see this...
Electricity
Rated Voltage  230V
Running Current  8.4A
Power Input  1,800W

1HP is 0.735 KW (electrical motor), I'll add 30% for losses. so 2hp = 2x 0.735 + 30%

wei kee, do you know the normal pvc pipe can fit hw many 4mm wires?

i confuse, at first was talking about water heater, then suddenly aircond

lol

anwyay, how about power consumption for water heater,how high it will be

I am using Alpha. Very good. Has been using same brand for more than 10 yrs+ but lately it spoilt so i bought new Alpha. Design is good too.

Because of losses.

i am using beebest sp2. but one thing i do notice after prolong used the 2.5mm wires gets warm. if you guys doing wiring i suggest go used 4mm.

the wiring is inside the pvc case. i guess >30min of continuous usage. i am using silent pump version, not so noisy and the pressure is better then euro uno.

actually i open up the case and touch the wire. i was doing some things in the another end at mcb. can feel the wire is warm.

If you water pressure is good than just off the pump lal...else just have to go alone with the stupid sound...

is all the new modal (Joven or Panasonic) both didn't have option to disable the use of pump any more? Or I missing something on the manual?
