Description

The Solar Water Heater is the most widespread application for producing hot water by utilizing solar energy. The main reasons for the success of the solar water heater in the global market are:

  • Low cost
  • Quick payback
  • Easy installation
  • Reliable operation

The main components of a solar water heater are the tank and the solar collector. The good performance of the system mainly depends on the technology of the collector that produces thermal energy. The quality of the tank, where the hot water is temporarily stored, is also important, both for the long-term durability of the system and for maintaining the hot water throughout the night.

    What I have to say corresponds maximally and strictly with objectivity, and even after four years, so I can criticize objectively. In northern Greece, in a maisonette by the sea, in Argyra, and in the bad weather that is very common with strong winds and southerly winds... no trace of erosion and rust at all (summer house) during the winter when we had to do interior work in late November, always hot water I have... Yes, and yet. In contrast to the Elco I bought for my main residence (with a one-year deviation later) with the motto "Pulling the Sun" which the latter satisfies okay but absolutely no comparison with Calpak .... Definitely Calpak and I will not risk anything to get the Mark 5 next time but again the Mark 4... Unbelievable

    This review is being made 22 months after the purchase of the CALPAK Mark 4, which was made in late September 2020 from the company KOKOTAS (the transaction was excellent & thank you very much once again). I delayed the review because I wanted to test the durability, specifications, and quality of this product over time. Well, yes! If I tell you that in 22 months I only turned on the electric water heater once, would you believe me? Even in winter - with 4+ cloudy days - I have hot water. Not naturally hot after 4 days of continuous cloudiness and nighttime temperatures below 8, but I have satisfactorily warm water. As for the summer months? It boils, steams, and fumes... Very hot water!! In conclusion, I am completely satisfied with the purchase and I believe I will have peace of mind for many more years.
