Generated explanation

The illustration compares relative recovery rates for electric, gas, and oil conventional tank-type water heaters using three vertical bars. Electric has the lowest recovery rate, gas is intermediate, and oil has the highest. Each bar contains a drawing of the corresponding storage water heater, with red and blue arrows indicating hot-water outlet and cold-water inlet flow. The gas heater has a top-mounted vent and a lower gas control, while the oil heater has a burner mounted near its base. No numerical recovery rates or units are provided.
