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

ic, any references for Amp vs thickness wire? I search around, found AWG (American Wire Gauge) shakehead.gif I roughly calculate, a 2HP aircon 5.4KW

said it is single phase 5400/240 = 22.5A, means I have to go for 4mm at least? 2.5 mm cant?

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.

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

I am using the instant shower heater, SMART series 18EP.
The shower head is big and i find it too heavy to hold for long. biggrin.gif

Also, water strength increase slightly with the help of pump but surely it is much noisy.
But i find it good to be noisy as ppl at outside maybe cant hear that i am singing while taking my shower. laugh.gif

Depend,

Instant water heater go from 100watt to 3600 watt cause you can adjust the heating element.

Storage water heater 3000 Watt (Joven).

Solar Power also need power, this you need to check the spec.

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.
