The fan should be installed as close to the ridge (high place) as possible to obtain the best ventilation effect.

The efficiency level of a solar collector refers to the thermal output or the "energy offset" of the system (the degree to which the solar water heating system reduces the use of traditional gas or electric energy). The following are the three main indicators of solar water heating efficiency.Solar

In indirect systems, the expansion tank must be properly sized for proper system operation. For customised thermal expansion tanks, the receiving volume must be sufficient to accommodate the expansion of the heat transfer fluid when the solar circuit goes into stasis. The following provides basic si

It is not recommended to drink directly. Solar water heaters convert solar energy into heat by absorbing solar energy, and store hot water in solar water tanks.
