What Is The Essency EXR? A Smarter Hot Water Upgrade For Brevard County Homes

Melbourne, United States – April 13, 2026 / Sun Plumbing /

When you choose the Essency EXR, you get an on-demand tank water heater designed to give you longer-lasting hot water by combining some of the best features of both traditional tank and tankless systems. Instead of working like a standard water heater, it uses 55 gallons of stored water as heat storage and transfers that heat to your domestic water through a heat exchanger as hot water is drawn. That gives you a high-capacity hot water solution that can deliver an 80-gallon first-hour rating in a 55-gallon footprint. If you are tired of running out of hot water, that difference can make a noticeable impact in daily life.

You also get a system designed to stand out by blending tank and tankless advantages in one unit. SmartCore Technology is built to support a maximum flow rate that lasts longer than other options, which helps the EXR replace an 80-gallon tank or even two 40-gallon tanks. If your home currently has a 55-gallon unit that is not keeping up, you can get the performance of an 80-gallon first-hour rating without needing a larger footprint. You also get a plug-and-play path away from gas, without fumes or exhaust pipes, and without needing electrical upgrades. The unit is also described as the easiest water heater replacement on the market, no matter what kind of technology you are replacing.

Another major advantage is the tank itself. You get an advanced double-wall polymer tank engineered to last 30 years. The tank is filled once during installation, and that water remains inside for the life of the unit. Because the tank is made of polymer composite, scale cannot form inside it, which helps extend the tank’s lifespan as well as the life of components like the heating elements. You also benefit from an atmospheric tank that does not require a relief valve or expansion tank, compatibility with all types of recirculation setups, a touchscreen with custom performance and savings modes, Bluetooth pairing, and the MyEssency app for software updates and alerts. On top of that, you have support from Sun Plumbing, whose trained technicians have served Brevard County for over 50 years and focus on helping you make smart plumbing decisions with clean, up-to-date professional service.
