Guys,

I am currently thinking of renovating my house in USJ. one of the things i am thinking of doing is upgrading the electrical wiring from single phase to 3 phase, but not too sure whether i should do it or not.

I am looking to put in 1 (1.5hp) air con, 2 (1hp) inverter air con and 1 (1hp) air con plus a joven 50 liter water heater, plus a clothes dryer plus 1 electric oven.

at least 3 aircons will be running full time from 5pm until 8am the next day, water heater for 3 bathrooms for normal mandi and clothes dryer pakai maybe 3 times a week.

My electricity bill never less than RM300.

Do you think single phase is sufficient or should i upgrade to 3 phase.
