Compact solar thermal heating Oksol

Oksol is a new integral, forced and autonomous system to be easily integrated into any house or building, it uses solar thermal technology for the production of hot water. It is self-contained, so it works without any external power source. A solar water heater which integrates in a single element the absorber, the forced recirculation system and the ACS accumulator of 150 liters of water.


  • Interacumulator. Space reduction. Integrated in the system with a capacity of 150 liters and corrosion resistant.
  • Static sink. More safety and durability. Protects the system from high temperatures and unexpected overheating.
  • Solar collector. Maximum performance. 2 m2 in stainless steel, with selective PVD treatment and with twice as much heat transfer liquid as a traditional solar collector (4 liters).
  • Solar panel. Autonomy and savings. Integrated in the system with a capacity of 150 liters and corrosion resistant.
  • Primary circuit pump. Autonomy and efficiency. Direct current pump, modulates its speed according to solar radiation.
  • Laminating fireplace. Autonomy and efficiency. It manages to keep the water hot at the top, ready to be consumed.
  • Three-way thermostatic valve. Autonomy and security. Directs the primary flow to the DHW tank exchanger or to the static dissipator.
  • Pressure and temperature valve. Security element. Controls and guarantees the pressure and temperature of the DHW tank.
  • Safety valve. Security element. Controls and guarantees the pressure of the primary circuit.

The advantages of Oksol.

  • It improves the amount of heat transferred by the solar liquid to the cold water in the tank, as there is no heat loss.
  • Savings of 3 to 5% on heat loss due to thermal exchanges.
  • It does not require an electrical connection.
  • No electricity consumption. All the equipment has a photovoltaic cell responsible for supplying the circulator.
  • Replacement of long runs of large-diameter plastic secondary circuit pipelines with their accessories, insulation and fixings, for very short runs of
    small diameter.
  • There is no need for a technical room with its accumulators, plate heat exchanger, circulators, automatic filling units and their corresponding valves, pipes and insulation.
  • It does not use an electrical heatsink on the bridge.
  • The installation always in operation (stand-alone).
  • Fully self-regulated.
  • Flexible and adaptable to the needs of each building.
  • Saves space in the technical room.
  • Zero CO2 emissions.

Features Oksol.

  • Guarantee. Maximum confidence and protection based on Orkli’s experience and knowledge. * Pump 2 years.
  • Functional design. An attractive design, in harmony with the design of the building where it is installed. All the elements in one.
  • Easy installation. Easy to assemble, just connect the water inlet and outlet.
  • Durability, high resistance. Impact resistant and very durable material. Its compact and robust design and easy assembly guarantee a very long service life.
  • It does not require an electrical connection for its operation.
  • No heat loss due to the route and size of the pipes.
