A new technology called the Essency Water Heater is designed to combine the advantages of both tank and tankless systems. These innovative heaters deliver hot water on demand while installing similarly to a traditional tank unit.
What Is an Essency Water Heater?
An Essency water heater is the first ever on demand tank water heater. This system blends the storage capacity of a traditional tank with the performance of a tankless heater. The unit installs like a standard tank heater but provides performance similar to tankless systems, giving homeowners continuous hot water without complicated installation requirements. One of the biggest advantages is its high output capacity. It produces significantly more hot water than most traditional electric tanks of the same size.

How Essency Water Heater Technology Works
Unlike traditional water heaters that heat and store the same water you use, the Essency system uses a thermal battery design.
Here’s how it works:
- The internal tank stores water that acts as a heat source, not the water you use.
- When you turn on a hot water tap, fresh household water flows through a large heat exchanger inside the unit.
- Heat from the stored water is instantly transferred to the incoming water, producing hot water on demand.
Because the water in the tank stays inside the system for its entire lifespan, the tank doesn’t experience the same corrosion problems as traditional steel tanks.
Benefits of Essency Water Heaters

- Continuous Hot Water: Essency heaters are designed to deliver large volumes of hot water quickly. Some systems can produce enough hot water for multiple simultaneous uses.
- Longer Lifespan: The tank is made from polymer composite materials that resist corrosion and scale buildup, which can significantly extend the system’s lifespan up to 30 years compared to steel tank heaters.
- Low Maintenance: Traditional tank water heaters require flushing to prevent rust and sediment buildup. Essency systems eliminate many of these maintenance needs because the tank water never mixes with household water.
- Energy Efficiency: Because heat is transferred only when hot water is needed, the system reduces wasted energy compared to constantly reheating stored water in a traditional tank.
- Easy Installation: Typically installs using standard water heater connections, making it a convenient upgrade.
Is an Essency Water Heater Right for Your Home?
Essency water heaters can be a great option for homeowners who:
- Frequently run out of hot water
- Want tankless style performance without major installation upgrades
- Prefer a longer lasting, low maintenance system
- Are replacing an aging electric tank water heater
