Recovery in plumbing typically refers to the ability of a water heater to heat and supply hot water after being depleted. It is measured in gallons per hour (GPH), indicating how much hot water the unit can produce within an hour. A high recovery rate means that the water heater can quickly replenish hot water, making it suitable for households or facilities with high hot water demands. Factors affecting recovery include the heater’s energy source (electric, gas, or oil), BTU rating, and tank insulation. Understanding the recovery rate is crucial for selecting a water heater that meets the specific hot water needs of a building.
