Screw-In Lime Life Water Heater Element, 240V

Camco 2953 – 4500W 240V Lime Life Ultra Low Watt Density Element for Electric Water Heaters

The Camco 2953 Lime Life element is engineered for use in electric water heaters in areas with high mineral content. Operating at 4500 watts and 240 volts, this screw-in style element utilizes ultra low watt density to minimize lime and scale buildup, making it ideal for hard water applications where standard elements often fail prematurely.

Performance and Design

This element is constructed with nickel-plated stainless steel sheath material and incorporates high-grade magnesium oxide insulation to enhance thermal conductivity while maintaining electrical insulation integrity. The 2953 is dry-fire protected and built for durability in demanding field conditions.

Product Specifications

• Voltage: 240V AC
• Wattage: 4500W
• Element Type: Ultra low watt density
• Sheath Material: Nickel-plated stainless steel
• Insulation: Magnesium oxide
• Thread Size: 1” NPSM
• Minimum Tank Diameter: 15 inches

Application Suitability

Designed for residential electric water heaters requiring screw-in style elements. The ultra low watt density format significantly reduces the operating surface temperature, which helps prevent scale accumulation, especially important in municipal or well systems with high calcium or magnesium levels.

Installation Considerations

Installation requires tank drainage and isolation from electrical supply. Proper sealing using the included gasket and torqueing to specification is essential to ensure leak-free operation. Installation should comply with applicable plumbing and electrical codes. Professional installation is advised unless the installer is qualified to perform electrical and plumbing work safely.

Contractor Notes

• Hard Water Solution: Preferred replacement in hard water regions where standard elements fail due to lime scaling.
• Service Ready: Commonly used in routine maintenance or upgrade scenarios for existing electric water heaters.
• Performance Stability: Maintains output efficiency while extending the service life of the element.
