This is all normal in the Philippines. Electricity isn't limited, but many households only need to run phone chargers and a light for each room. Most people have fans, but you can get by without if you have an open design and some shade. I'm not sure I have ever seen anyone use a vacuum here (not many people have carpeting.) You might be surprised at how well you can get by without a fridge. Buy your meat and veggies fresh. Cook only the food people will eat (no leftovers.) Buy ice and other cold things from a community store. I'm assuming the hot water thing is for bathing during the winter, this isn't an issue in the Philippines.
