The Story

The MRCOOL® Low Boy 38-Gallon Electric Tank Water Heater provides consistent, energy-efficient hot water tailored to meet the daily needs of any home. Engineered for strength and reliability, this compact model helps lower energy usage without compromising performance—making it a smart and environmentally responsible solution for modern households. Outfitted with high-efficiency heating elements, the unit quickly reaches your desired temperature, reducing wait times and enhancing everyday comfort. Its dual stainless steel tank and ceramic-coated heating element delivers up to 50% greater resistance to corrosion compared to standard systems—offering increased durability and reduced upkeep.

Additional premium features, including an anti-bacterial tank, built-in self-cleaning function, and patented Rare Earth Anode rod, support long-term efficiency and clean water quality. With a low-profile design, the heater is perfect for installations in spaces with restricted vertical clearance—like beneath countertops, inside short closets, or under stairwells. Easy-access temperature controls make adjustments simple, while the whisper-quiet operation ensures minimal noise. Integrated safety protections against overheating, dry firing, and pressure buildup provide added peace of mind.

Covered by a 10-year parts warranty, 10-year tank warranty, and 1-year limited labor warranty, the MRCOOL® Low Boy Electric Tank Water Heater combines compact convenience, powerful performance, and dependable longevity you can count on.
