The best capacity for a water heater drip pan matches the base diameter of the heater with 1–2 inches of clearance and holds at least 1–2 gallons. This volume accommodates minor leaks and gives time to address issues before overflow, protecting surrounding floors and structures. Options like the All Purpose Round Drip Pan 36" offer significant containment for large systems, while more compact pans like the Drain Pan 24" Natural Rubber are suitable for standard heaters. With a variety of sizes, you can select the right capacity for your needs.
