A water heating system typically provides hot water for uses such as bathing, cleaning, cooking, and space heating. Common water heating systems include gas, electric, tank, and tankless designs, along with the controls, piping, and insulation required to feed hot water to the intended location. When installed, these systems must comply with the Building Energy Efficiency Standards (Energy Code). This ensures energy savings for the building owner.
