Energy flexibility with unique tank-in-tank design for HP+Solar

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 TRIPLECOIL — OTRC is ideal for heat pumps with three way valve for DHW priority up to 12 kW in combination with solar collectors up to 12 m², and for heating demands in households up to 400 m². The smooth piped, scale-resistant heating coils are situated so that thermodynamics always ensure the most efficient use of energy source - solar and HP or similar is prioritized in the lower heating coil, heat pump in the buffer tank for heating, and for DHW in the upper heating coil. OPTIMA TRIPLECOIL 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.

Advantages: 

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.
