OSO OPTIMA GEOCOIL OGC
OPTIMA GEOCOIL
The ultimate tank-in-tank unit for heat pumps up to 12kW
OPTIMA series are tank-in-tank units with unique and patented solutions to increase Seasonal Performance Factor (SPF) for heat pumps vs. traditional tank-in-tank units. The buffer tank and domestic hot water tank (both made in stainless steel) are integrated in a single unit, increasing efficiency, reducing footprint as well as installation time. The smooth piped, scale-resistant heating coil is another advantage. OPTIMA boasts class-leading insulation capabilities, while maintaining a higher temperature than others (75 °C) in the DHW tank for unbeatable performance and more hot water in a smaller unit.
OPTIMA GEOCOIL — OGC is ideal for heat pumps with three way valve for DHW priority up to 12 kW, and for heating demands in households up to 300 m². The smooth piped, scale-resistant heating coil in the DHW tank has a is carefully calculated surface area for efficient DHW production from the heat pump. OPTIMA GEOCOIL has full electric back-up for the heating system for ultimate peace of mind, as well as ultra-grade INCOTEC immersion heater as booster for the domestic hot water unit. Adjustable hot water draw-off temperature (prevents scalding) to the taps is ensured by the factory fitted UX mixing valve with maximum water flow rate of 0,7 L/s.

MORE HOT WATER
Substantially higher temperature (70°C+), highly efficient mixing valve (no scolding), minimal heat loss and optimal design features gives up to 20 % more hot water and class leading capacity.
PRO INSULATION
The use of NANOPUR™ with insulation values far surpassing Pentane, often in combination with VACUUM panels, ensures minimum heat loss and class leading energy efficiency.
STRONGER
EVERLAST™ titanium alloyed stainless steel in combination with OSO’s unique ULTRAWELD™ system and state-of-the-art passivation process equals class leading corrosion resistance.
LIGHTER
EVERLAST™ titanium alloyed, high tensile strength, stainless steel equals lower weight and efficient use of resources. OSO products are more than 40 % lighter than enameled products.
BUILT TO LAST
INCOTEC™ el. immersion heaters with ultra high-grade Incoloy 825 stainless, DZR brass, zinc-free soldering and carefully calculated surface loads results in maximum durability in hard water.
