Conventional water heaters feature a tank where water is collected, heated, and kept hot until it is used. These appliances are typically quite large in size, as they store hot water for the entire household. Most tanks hold anywhere from 20 to 100 gallons of hot water at a time. Given their size, water heating appliances are usually installed in areas of the house where they don’t get in the way. This could be a basement, garage, or even a dedicated utility room. Some homeowners install their tanks in the attic, but this is often not a great idea, as if the heater leaks or bursts, the water will cause a lot of damage to the lower levels of the home.
If your home has two or more water heaters, these will usually be installed in different parts of the house.
