Buying Guide: Key Factors to Consider
What wattage do I need? Higher wattage (like 2000W) heats water faster but requires a compatible tank and electrical supply. For RVs, 1400W–1440W variants are common and balance performance with power availability. How do I know compatibility? Look for screw-in (NPSM) bushings, gasket presence, and the correct diameter for your tank’s opening. Can I mix brands? Compatibility is best when matching the model family (Atwood, Suburban, SW series) or using a universal screw-in option with appropriate bushing. Is copper sheath important? Copper sheaths offer corrosion resistance and longevity in mineral-rich water. Do I need extra installation hardware? Some products include a hex wrench or PTFE tape; others require you to source tools separately.
Practical Tips for Installation and Use
- Before replacing, power down the heater and drain the tank to avoid scalding or electric shock.
- Check tank diameter and bushing thread size (NPSM) to avoid leaks or misfits.
- Use provided gaskets or replace with new ones to ensure a watertight seal.
- Replace mineral deposits in RV systems by flushing the tank after installation, if applicable.
- Store spare elements and a small wrench for field replacements during trips.
FAQ
- What wattage should I choose for a home water heater? Choose a wattage compatible with your tank size and electrical service; 2000W is common for quick recovery in standard tanks if wiring supports it.
- Are RV elements compatible with home water heaters? Some are, but RV-specific models match different tank configurations; verify model compatibility before buying.
- How do I know if a screw-in element will fit my tank? Check the thread type (1-1/2 inch NPSM), diameter, and the presence of a gasket; measure internal tank diameter if needed.
- Can I install an element without the gasket? A gasket is typically required to seal and prevent leaks; use the recommended gasket or a compatible replacement.
- Is a copper sheath better than other coatings? Copper sheaths offer improved durability and mineral-resistance in many water conditions, aiding longevity.
- What maintenance helps extend element life? Regularly flush tanks to reduce mineral buildup and inspect for corrosion or signs of wear after replacements.
