At 20.5\" in diameter and 60.1\" tall, the MTWH04550ET is purpose-built for utility closets, narrow mechanical rooms, and tight vertical spaces that would otherwise rule out a 50-gallon unit entirely. The same 4,500W element at 240\/208V drives performance across a 90–150°F adjustable range, and an anti-bacterial enameled tank paired with a ceramic-coated heating element keeps corrosion resistance built into the foundation. A patented Rare Earth Anode rod outlasts conventional magnesium rods by 50%, while a self-cleaning flow guide continuously clears sediment without manual intervention. AHRI Certified and cULus Listed, and backed by a 10-year parts warranty, a 10-year tank warranty, and a 1-year limited labor warranty.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50-Gallon Tall Configuration\u003c\/strong\u003e: The MTWH04550ET delivers a full 50-gallon hot water reserve in a tall, narrow profile measuring 20.5\" in diameter and 60.1\" in height, powered by a 4,500W element at 240\/208V with a 90–150°F temperature range and a max working pressure of 149.39 PSI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpace-Optimized Footprint\u003c\/strong\u003e: With a diameter more than 3\" slimmer than the standard 50-gallon MTWH04550E, the ET configuration installs cleanly in utility closets, narrow alcoves, and mechanical rooms where a conventional tank cannot be accommodated without sacrificing capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-Bacterial Enameled Tank\u003c\/strong\u003e: A 2mm steel shell with a 0.25–0.5mm anti-bacterial enamel lining resists corrosion and inhibits bacterial growth, protecting water quality and structural integrity through years of high-demand daily use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented Rare Earth Anode Rod\u003c\/strong\u003e: MRCOOL®'s proprietary Rare Earth Anode rod outlasts standard magnesium anode rods by 50%, providing superior internal tank protection and a measurably extended service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCeramic-Coated Heating Elements\u003c\/strong\u003e: Enamel-coated heating elements resist scale accumulation and corrosion, maintaining consistent heat transfer efficiency and reducing the maintenance burden over the full life of the unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Guide Self-Cleaning\u003c\/strong\u003e: An integrated flow guide agitates sediment during normal operation, continuously flushing mineral deposits before they compromise heating efficiency or tank integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Brass Ball Valve\u003c\/strong\u003e: A solid brass ball valve at the 3\/4\" NPT water connection delivers a corrosion-resistant, leak-proof shutoff built to outlast plastic alternatives across years of continuous service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry-Backed Warranty\u003c\/strong\u003e: Protected 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.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MRCOOL","offers":[{"title":"Default Title","offer_id":53296988127545,"sku":"MTWH04550ET","price":792.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0292\/1336\/0188\/files\/mrcool_4_9938d0f1-dd90-42c6-b3b1-1a3cc8152056.png?v=1778790206","url":"https:\/\/chillminisplits.com\/products\/mrcool-heatwise%e2%84%a2-4500-watt-tall-electric-tank-water-heater-50-gallon-capacity-mtwh04550et","provider":"Chill Mini Splits","version":"1.0","type":"link"}
