What part do I need to replace the heating elements in the VEVOR FJI-POR-70S2 18-gallon 1600W water heater?

For the VEVOR FJI-POR-70S2 (18-gallon, 1600W unit), you need a specific 1600W immersion heating element. While the manual identifies the component as an "Immersion Heating Element" and notes it is protected by an enamel coating, it does not provide a specific manufacturer part number for ordering.To ensure you get the correct replacement part, please consider the following:Contact VEVOR Support: Since this is a specialized immersion element with an enamel coating, it is best to contact VEVOR customer support directly for the exact OEM replacement part.Specifications: If sourcing a generic part, you must match the 1600W wattage, the voltage (typically 110-120V for this model's US configuration), and the specific flange or thread size used for the side connection.Safety Warning: The manual emphasizes that maintenance on heating elements should be performed by a qualified professional. Always disconnect the power supply and drain the tank before attempting to inspect or replace the element.

What kind of extension cord can I use with the VEVOR FJI-POR-70S2 18-gallon electric water heater?

For the VEVOR FJI-POR-70S2 18-Gallon Electric Water Heater, it is generally recommended to avoid using an extension cord if possible. High-wattage appliances like this 1600W heater draw significant current, which can cause extension cords to overheat, potentially leading to fire or electrical failure.If you must use an extension cord temporarily, ensure it meets the following safety requirements:Heavy-Duty Rating: The cord must be rated for at least 15 Amps and 1875 Watts to handle the 1600W load of the heater.Wire Gauge: Use a 12-gauge (12/3) or 14-gauge (14/3) grounded extension cord. A lower gauge number indicates a thicker wire, which is safer for high-power appliances.Length: Keep the cord as short as possible (e.g., 25 feet or less) to prevent voltage drop and overheating.Grounding: The cord must have a three-prong grounded plug.Warning: The manual states that the unit should be connected to a "suitable electrical outlet" and installed by a qualified professional in accordance with local electrical codes. Using an undersized or low-quality extension cord can void your warranty and create a serious safety hazard.
