OPTIMA COIL – OC – covers the hot water requirement for approx. 6 people and the heat demand in homes up to approx. 400 m² in a single unit. OPTIMA COIL is very suitable for heat pumps where hot water prioritization is not used. The heat pump preheats the hot water efficiently via the stainless steel heat exchanger and the bottom of the hot water tank with a total heating surface of 1.4 m² integrated in the buffer tank. OPTIMA COIL is also available for high temperature systems and is a perfect replacement for oil boilers. All OPTIMA models have an electric element for the heating system and electric supplemental heat for the hot water, which further increases performance.
OPTIMA is the market’s most advanced and energy efficient tank-in-tank products, with foam insulation and patented solutions to increase hot water production from alternative energy sources. The OPTIMA series integrates both stainless steel buffer tank and heat exchangers in one unit, and takes up minimal space. The mixing valve lowers the outgoing hot water temperature and prevents the risk of scalding. OPTIMA is particularly well suited as preparation for heat pump installation in the future, and can supply both heat and hot water with electrical elements.
WHY CHOOSE OPTIMA COIL?
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.
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.
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.
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.
