At 22.8\" in diameter and 32.1\" tall, the MTWH04538EL fits installations where vertical space is limited but a 28-gallon reserve falls short of household demand. Like the 28EL, it ships with an included energy cover that curtails standby heat loss and trims operating costs from day one. A 4,500W element at 240\/208V powers the unit across a 90–150°F adjustable range, while an anti-bacterial enameled tank and ceramic-coated heating element build corrosion resistance into the core. A patented Rare Earth Anode rod outlasts conventional magnesium rods by 50%, and a self-cleaning flow guide handles sediment automatically throughout the unit's service life. AHRI Certified and cULus Listed, with 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\u003e38-Gallon Low-Profile Capacity\u003c\/strong\u003e: The MTWH04538EL delivers a 38-gallon hot water reserve in a low-clearance footprint measuring 22.8\" in diameter and 32.1\" tall, 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\u003eIncluded Energy Cover\u003c\/strong\u003e: The MTWH04538EL ships with an energy cover included, reducing standby heat loss from the tank exterior and lowering day-to-day operating costs without any additional purchase or accessory required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Clearance Installation\u003c\/strong\u003e: At 32.1\" tall, this unit is engineered for restricted-height applications including stairwell closets, low utility rooms, and mechanical spaces where full-height tanks cannot be installed, delivering 38 gallons of capacity without the vertical footprint.\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 continuous high-demand 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 degrade efficiency or compromise 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":53296988062009,"sku":"MTWH04538EL","price":783.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0292\/1336\/0188\/files\/mrcool_13.png?v=1778790206","url":"https:\/\/chillminisplits.com\/products\/mrcool-heatwise%e2%84%a2-4500-watt-tall-electric-tank-water-heater-38-gallon-capacity-mtwh04538el","provider":"Chill Mini Splits","version":"1.0","type":"link"}
