Buying Guide
What size is right for my heater?
- Measure the heater’s footprint and compare inner/outer diameter to ensure a proper fit and drainage clearance.
- Consider cabinet or closet space; larger pans require more room around the unit.
What material should I choose?
- Durable plastic is common and resistant to rust; ideal for most residential electric heaters.
- High‑impact plastics resist cracking but verify temperature tolerance for higher heat scenarios.
What fittings are needed?
- Look for pans that include or are compatible with standard PVC drain fittings (1″ to 1.5″).
- Ensure your drain pipe size matches the pan’s fittings to avoid extra adapters.
What installation considerations matter?
- Check for pre‑cut openings that simplify fitting the drain line.
- Assess the installation surface; some pans may require level mounting for optimal drainage.
Are there any limitations to watch for?
- Some pans are tailored for gas heaters rather than electric; confirm model compatibility.
- Footprint size might not fit compact spaces like certain apartments or RV compartments.
