OSO OPTIMA GEOCOIL OGC

Water heater giving heat and hot water from heat pump

Water heater OPTIMA GEOCOILS – OGC – effectiveness and fast recovery time covers the hot water demand for at least 5 people and the heat demand in homes up to approx. 400m² in a single unit. OPTIMA COIL is suitable for heat pumps with hot water priority up to 12 kW, which transfer the heat efficiently via the stainless steel heat exchanger with a hot surface of 1.8m² integrated in the hot water tank. All OPTIMA models have an electric element for the heating system and an electric reheater for the hot water located above the heat exchanger, which further increases performance.

Water heater 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. Water heater 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 GEOCOIL?

  • Save approx. 650 kWh / year in relation to good, insulated boilers (300 L)
  • Integrated heat exchanger for heat pump ≤ 12 kW
  • Integrated stainless steel buffer tank saves approx. 1 m² floor space
  • Electrical element for both heating and hot water

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.
