Copper Coil System

Carisol thermosyphon copper coil pre heated evacuated tube solar water heaters are ideal for residential, commercial and institutional applications in solar hot water heating. This system works with very high water pressure therefore it output hot water with high pressure consistent with the cold water input, it uses high grade copper coil within the storage tank which is most efficient to deliver high instant rapid heat exchange of hot water for use, the water quality is always fresh as the hot and cold water flow are separated making its safe and comfortable to use. This high grade copper coil which is tested at high pressure cannot break. This system requires no pump or controller and come complete with storage tank, evacuated tubes, mounting frame and reflector plates. It works intelligently and is extremely reliable giving stable temperature and perfect operation.

These are the most common, efficient, reliable and cost effective form of evacuated tube solar water heater collector on the market and the best seller in our line of thermosyphon solar water heater because of its distinct advantages over the other systems as corrosion and scale build-up in the tank are almost totally eliminated, it can supply more hot water than its storage capacity, it is the suited heater in areas with corrosive water (high in calcium and magnesium), the water is always fresh and it is most affordable.

  1. Instant heat exchange; plentiful hot water for use.
  2. Pressurize operation output fresh water qualities.
  3. Electrical back-up element.
  4. Uses non-breakable high grade copper coil.
  5. It can be combined with the architecture perfectly.
  6. It can be combined with existing pipeline.
  7. It is not affected by the local water quality as it suits any water.
  8. Works intelligently and reliable. It provides more hot water than the capacity of the tank.
  9. Reliable and efficient twin-glass vacuum solar tubes.
  10. Copper heat coil for rapid heat exchange thus heating water very rapidly.
  11. Suitable for mains pressure water (up to 8 bar/116psi).
  12. Corrosion resistant copper.
  13. Plastic power coated galvanized frame.
  14. Powder coated steel and stainless steel storage tanks.
  15. Output water temperature is stable, so it is very comfortable and safe to use.
  16. The perfect solar collector for domestic solar water heater systems.
  17. Ideal for commercial solar water heating applications.

This collector types collects and convert the sun€™s energy into thermal energy with high efficiency using vacuum and heat transfer. The vacuum prevents any conductive or convective heat loss to the environment from the absorber. The selective coating in the inner cover of the evacuated tubes ensures high energy absorption and low heat radiance losses. In this solar collector the water fill the tubes and storage tanks, cold water falls to the bottom of the tube where it is heated by the sun as the water is heated it rises up into the storage tank. This cycle repeats itself continuously as long as the sun shines thus obtaining extremely high temperature of the water in the solar storage tank, but rather than using the water in the tank directly it uses a copper coil heat exchanger inside the tank which provides a wide area for heat transfer.

Hot water is obtained when the cold water is injected into the high efficiency copper coil heat exchanger, as the water flows through the coil it absorbs heat rapidly at the temperature of the hot water inside the solar collector storage tank and output hot water at a stable temperature.

The evacuated tubular collector are quasi-tracking in four seasons, which is to say that as the sun tracks across the sky, about the same absorber area is facing the sun all the time, since the absorber surfaces are cylindrical. The collector will be in operation as long as sun shines.

Our thermosyphon heat pipe evacuated tube solar water heaters are available in following standard sizes but we can custom manufactured to any required size.

Each Thermosyphon Solar Water Heater System comes standard with the requisite number of evacuated tubes, an outdoor storage tank that is mounted directly to the top of the solar collector that acts as water storage and heater manifold, electric heater element, mounting hardware kit and reflector plates.
