Product Description
The MRCOOL® MTWH04550E 50-Gallon Electric Tank Water Heater delivers high-capacity hot water with a 4500-watt heating element, advanced corrosion resistance, and long-term durability.

Long Product Description
The MRCOOL® 50-Gallon Electric Tank Water Heater (Model MTWH04550E) is designed for households with higher hot water demand, offering dependable capacity, fast recovery, and enhanced durability. Ideal for families, multi-bath homes, and high-usage applications, this electric tank water heater ensures consistent hot water for showers, laundry, dishwashing, and everyday comfort.
This model features a dual stainless steel tank paired with a ceramic-coated heating element, providing up to 50% greater corrosion resistance compared to traditional tank water heaters. These materials help extend tank life, maintain performance, and reduce long-term maintenance costs. An anti-bacterial tank lining and self-cleaning function work together to limit sediment buildup and help maintain cleaner hot water over time.
Powered by a high-efficiency 4500-watt electric heating element, the MRCOOL MTWH04550E heats water quickly and minimizes recovery time between uses. The unit operates on 208/240V single-phase power, making it compatible with most residential electrical systems.
Despite its larger 50-gallon capacity, the unit maintains a space-efficient footprint, allowing installation in utility rooms, basements, garages, and other tight spaces. User-friendly temperature controls make it easy to fine-tune comfort while managing energy consumption.
Backed by a 10-year tank warranty, 10-year parts warranty, and 1-year limited labor warranty, the MRCOOL® 50-Gallon Electric Tank Water Heater is a long-term investment in reliability, efficiency, and peace of mind.
