Buying Guide
What size do I need?
Choose a pan with enough width and depth to cover the footprint of your heater and catch potential drips. Larger pans offer more protection but require more space and may not fit in tight closets.
What material should I pick?
Plastic pans are lightweight and affordable; stainless steel offers superior corrosion resistance in humid spaces; aluminum provides good durability with lighter weight. Your environment and heater type influence the best material choice.
Drain fittings and connections
Look for pans with compatible drain fittings (1″ PVC, 1-1/2″, etc.). Flexible adapters are advantageous for tankless or multi-pipe setups. Ensure the pan’s drain size matches your existing drain line to simplify installation.
Installation considerations
Consider whether the heater sits in a cabinet, closet, or utility room. Some pans require mounting clearance or specific mounting hardware. For wall-mounted tankless units, stainless steel pans often provide longer-term protection against moisture.
Durability and maintenance
Stainless steel pans resist rust and corrosion, while plastic pans are more prone to wear in humid environments. Check for welded seams and quality fasteners in metal pans to minimize leaks over time.
