In order to make the water circulation in the attemperater more reasonable, the water side of described attemperater circulation water inlet pipe is arranged on the upper end in the attemperater, and the water inlet end of attemperater circulation water inlet pipe is arranged on the lower end in the attemperater.
In order to increase flowing of liquid, the end that described every endothermic tube is connected with first collector is lower than an end that is connected with second collector respectively.
In order to increase the freeze proof effect of heat collector collector, the principle of further freezing in order, first collector of the present utility model and second collector are joined successively by the metal tube of two different-diameters respectively form at least, and the metal tube of minor diameter is arranged on the lower end, and large diameter metal tube is arranged on the upper end.
In order to enlarge the area of heat collector, and can improve the anti-freezing property of endothermic tube, described flat plate collector is two groups, and wherein one group of flat plate collector is arranged on a side of another group flat plate collector.
In like manner, connect same collecting main respectively between the every endothermic tube of described two groups of flat plate collectors, the water side of collecting main is connected with attemperater.
In order to prevent the deposition of incrustation scale, the lower end of described first collector is provided with first sewage draining valve.
In like manner, the lower end of described second collector is provided with second sewage draining valve.
Below attemperater and flat plate collector, be provided with rack of solar water heater.
The pipeline that flat plate collector is connected with attemperater covers insulating tube outward.
