The geothermal storage tank is designed to capture and store the preheated hot water generated by your geothermal unit. It is engineered specifically for geothermal applications and includes unique features that make installation and operation easy. Large water connections, premium insulation, built-in temperature sensors and chilled water capabilities make this tank the perfect fit for your geothermal system.

Anode Rods

GeoStore tanks feature a glass-lined tank with two anode rods. The anode rod is used to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This extends the life of your tank.

Heating Element

Sandhog low watt density 4500-watt Incoloy Steel Heating Element is designed to last 2 to 3 times longer than standard copper heating elements.

Diffuser Dip Tube

All ‘cold’ connections feature a diffuser dip tube to reduce lime and sediment buildup and maximize equipment efficiency. Made from PEXAN, a cross-linked polymer, these connections can withstand long-term exposure to temperatures up to 400° F.

Temperature/Pressure Relief Valve

Factory installed temperature/ pressure relief valve. UL 174 Certified for household electric water heaters and factory approved for chilled water storage.

Drain Valves

Brass tamper-resistant drain valve provides durability and longer life than plastic valves.

Chilled Water Rated

The GeoStore is rated to a chilled water temperature of 40°F
