    In the same years Ariston Thermo acquired Racold, [3] India's largest water heaters' manufacturer, and opened its first wholly owned plant in China. The early 21st century saw the acquisition in 2001 of several historical companies and brands in the heating and burner sectors, namely: Chaffoteaux, Elco, Cuenod and Rendamax.

  3. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    When a solar water heating and hot-water central heating system are used together, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. However ...

    The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.

    The operating conditions' optimization of this system is the main challenge, because there are two opposing trends of the performance of the two sub-systems: by way of example, decreasing the evaporation temperature of the working fluid increases the thermal efficiency of the solar panel but decreases the performance of the heat pump, and consequently the COP.
