Buying Guide
Key considerations when choosing a water heater igniter include compatibility, ignition type, and installation ease. If your unit uses FVIR technology, prioritize assemblies labeled for Reliance or compatible brands. Piezo igniters provide a battery-free spark, while pilot/igniter assemblies include infrared or thermocouple components, which can improve reliability in high-draft or dusty environments. Durability matters; look for ABS or stainless components and gasket compatibility to prevent leaks. Installation ease varies by model—some parts mount in the original location with minimal wiring, while others require precise alignment of the spark probe and ground.
Compatibility depth matters for RV and residential units alike. Ensure the replacement kit covers your exact model range and check for included gaskets or seals to prevent future leaks. If in doubt, consult the manufacturer’s model numbers or seek professional guidance to confirm the correct part. Finally, consider availability and return policies—replacements that ship quickly and come with clear installation instructions can minimize downtime during a repair.
