Tips for living without hot water?

For hand sanitizing, use some of those antibacterial wipes or the sanitizing gel. For pet-washing, take the pet to a groomer, pet self-wash place, or a friend's house, only when they really need it. For washing yourself, get a plastic bucket, say two gallons. Heat a large pan of water on the stove, add it to cold water in the bucket, take it into the tub or shower. Get a washcloth and soap yourself up, use a cup to pour water to rinse yourself. You'll be surprised how little warm water you really need. For doing dishes, same process as the 'shower', and at least you have running water to rinse them in even if it's cold.
