The KNOX SALES COMPANY 210343 is a screw-in replacement heating element designed for residential and light commercial electric water heaters. Operating at 5500 watts and 240 volts, this element provides the thermal output required to maintain consistent water temperature in standard tank-style water heater applications. It is installed by licensed plumbers or qualified service technicians as part of routine maintenance or failure replacement procedures. The screw-in design allows for straightforward removal and installation using standard element socket tools without requiring specialized equipment.
This element is suited for electric storage tank water heaters that accept screw-in style elements. It is a common replacement item in residential settings where the lower or upper element has failed due to scale buildup, sediment accumulation, or normal wear. Service technicians typically stock elements of this wattage and voltage rating for high-frequency service calls on standard 240-volt electric water heater systems.
Designed as an OEM-style screw-in replacement element for standard residential and light commercial electric storage tank water heaters accepting 5500W 240V screw-in elements.
Installation should be performed by a licensed plumber or qualified service technician. Before replacing the element, shut off electrical power to the water heater at the breaker and close the cold water supply valve, then drain sufficient water from the tank to expose the element port. An element socket wrench is the standard tool for removal and installation. Follow all applicable local plumbing and electrical codes, including IPC and NEC requirements, when servicing water heater components.
