2500W of power can heat 5 gallons of water in a few minutes. Before inserting the heater, ensure it is fully submerged in water, then connect to a 220V power supply. Equipped with a high-quality stainless steel protective cover, this submersible water heater prevents direct contact with heating elements and allows faster heat dissipation through holes in the cover.
