Made of modular EPP foam components and other non-corrosive elements, our tank ships efficiently and assembles in minutes. Easily installs in difficult to reach spaces and tight mechanical rooms.

With an R=18 energy retention value, the temperature loss in our Thermal Tank is less than 4 degrees F per day. A single 350 gallon tank stores 54 kw of thermal energy and can provide up to 1400 gallons of hot water per day.

The Thermal Tank is non-corrosive and unpressurized. Its lifespan exceeds traditional tanks by 3x. All components can be replaced individually and fully recycled. The water in our tank is a working fluid, similar to a battery, which never leaves the tank. A high-performance heat exchanger transfers the energy to the load side. No minerals are introduced to the tank after a one-time fill.

The Thermal Tank is available in 350, 500, and 700 gallons. Several tanks can be combined to provide larger thermal storage volumes. The tank can be combined with various energy sources for ambient, solar, or waste energy capture. It can also serve as a component of a traditional system, providing additional storage and buffer capacity.

Our competitive product cost paired with high performance and longevity makes the Thermal Tank an attractive investment with short payback periods. The increased thermal storage in a hot water system allows our clients to lower operating costs, avoid peak rate cycles, and lower demand charges.
