The MRCOOL® HeatWise™ 30-Gallon Electric Tank Water Heater is built for homeowners who refuse to compromise on reliability. Running on a 4,500W element at 240/208V, it heats water across a 90–150°F range, delivering consistent, on-demand performance day after day. Inside, an anti-bacterial enameled tank pairs with a ceramic-coated heating element and a patented Rare Earth Anode rod that outlasts standard magnesium rods by 50%, keeping corrosion and costly repairs at bay for the long haul. A self-cleaning flow guide reduces sediment buildup automatically, while the durable brass ball valve ensures a secure, lasting connection. AHRI Certified and cULus Listed, it backs every drop of hot water with a 10-year parts warranty, a 10-year tank warranty, and a 1-year limited labor warranty.

• 30-Gallon Capacity: The MTWH04530E delivers a dependable volume of hot water suited for small to medium households, powered by a 4,500W element at 240/208V with a temperature range of 90–150°F and a max working pressure of 149.39 PSI.
• Anti-Bacterial Enameled Tank: The inner tank features a 2mm steel shell with a 0.25–0.5mm anti-bacterial enamel coating that inhibits bacterial growth and resists corrosion, protecting water quality and structural integrity over years of continuous use.
• Patented Rare Earth Anode Rod: MRCOOL®'s proprietary Rare Earth Anode rod outlasts conventional magnesium anode rods by 50%, providing superior tank protection and dramatically extending the service life of the unit.
• Ceramic-Coated Heating Elements: Enamel-coated heating elements resist scale buildup and corrosion, maintaining efficient heat transfer and reducing maintenance demands over the full life of the heater.
• Flow Guide Self-Cleaning: An integrated flow guide system actively agitates sediment within the tank during operation, flushing mineral buildup before it can accumulate and degrade efficiency or tank integrity.
• Durable Brass Ball Valve: A solid brass ball valve at the water connection delivers a robust, leak-resistant shutoff that outperforms standard plastic fittings in both durability and long-term reliability.
• Easy Installation: Standard 3/4" NPT water connections and a straightforward electrical hookup make for a clean, accessible install whether replacing an existing unit or outfitting a new location.
• Industry-Backed Warranty: Covered by a 10-year parts warranty, 10-year tank warranty, and 1-year limited labor warranty for single-family residential installations, with AHRI Certification and cULus Listing confirming compliance with North American safety and performance standards.
