GEOTHERMAL DOMESTIC HW & HYDRONIC
STORAGE TANKS

ENERGY EFFICIENT
WaterFurnace geothermal storage tanks, available in 80 or 119 gallon capacities, are specifically designed to provide consistent water temperature and constant hot water in geothermal systems! Large plumbing connections, 2 in. (R-16) insulation, built-in temperature sensor, and chilled water approved make these tanks the perfect choice for geothermal hydronic systems. Complete with extra plumbing connections and deluxe features, our storage tanks are also a great choice for geothermal domestic hot water systems.

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

Reliability
Glass-lined tank with two anode rods. Primary and secondary aluminum anode rods provide maximum protection against corrosion. Brass tamper-resistant drain valve provides durability and longer life than plastic valves. Sandhog low Watt density 4500 Watt Incoloy Steel Heating Element is designed to last 2 to 3 times longer than standard copper heating elements. 6-Year Limited Tank and Parts Warranty.
