Hi Wellsfry and welcome.
We have a 3 bed 2 bath house, in summer we run a 1Hp unit in the bedroom at least 12 hours a day 7 days a week plus a 2.5Hp split system in the kitchen/living area, maybe 50+M2 2 or 3 times a week, 24cubic foot fridge/freezer, washing machine and occasionally the dryer when it rains all the time, 2 pedestal fans almost 24/7, water pump for deep well, mostly led lighting. Our bill in summer averages PHP 3,500 to 4,000. Currently through the cooler months it is 2 to 2.5 K.
We do use the water heater for showers in the cooler weather but not when it's hot.
Hope this helps.
Cheers, Steve.
