Knox Sales Company S245D-BAG Screw Plug Heater 4500W 240V

Product Description

The KNOX SALES COMPANY S245D-BAG is a screw plug immersion heater element rated at 4500 watts and 240 volts, designed for direct installation into water heater tanks and similar liquid heating vessels. This double-L style element threads into a standard fitting and transfers heat directly to the water or fluid surrounding it. Plumbers and water heater service technicians install this type of element as a direct replacement when an existing element fails, restoring heating performance without replacing the full unit. The double-L fold-back configuration maximizes surface area within a compact footprint, supporting efficient heat transfer in residential water heater applications.

This element is suited for residential water heater service where a screw plug style fitting is already present in the tank. Typical installations include electric storage water heaters found in homes and light commercial settings. The 4500W rating at 240 volts is among the most common specifications for residential tank water heater elements, making this a widely applicable replacement option for service calls involving loss of hot water or reduced heating efficiency.

Key Features

• 4500W heating capacity at 240 volts for strong residential water heating performance
• Double-L fold configuration for efficient heat distribution within the tank
• Screw plug mounting style for straightforward thread-in installation
• Designed as a direct drop-in replacement for failed water heater elements
• Compatible with standard screw plug element ports found on common electric tank water heaters

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Before beginning work, shut off electrical power to the water heater at the breaker panel and close the cold water supply valve to the tank. Allow the tank to cool and drain as needed before removing the existing element. Follow applicable local plumbing and electrical codes, and verify the replacement element wattage and voltage ratings match the existing wiring and thermostat configuration before energizing the unit.
