The utility model compared with prior art, advantage is:
(1), preheating inner bag and hot water inner bag be integrated in the water tank, and is arranged above and below, compact conformation is reasonable, occupies little space, installation and maintenance is simple and convenient.
(2), the preheating inner bag directly admits cold water to come in, lower temperature helps the exchange heat with solar thermal collector.
(3), running water enters the hot water inner bag after through the heating of preheating inner bag, can Fast Heating reaches the serviceability temperature of hot water, can satisfy the demand of big water consumption, the hot water inner bag remains higher temperature, and round-the-clock hot water supply can be provided.
(4), preheating water tank's lowest set temperature is general similar with room temperature, so the warm water in the preheating inner bag does not have heat to be dispersed in the air substantially, and the hot water inner bag of smaller size smaller also has only heat seldom to distribute behind the employing polyurethane heat insulation material.When particularly not having hot water to consume when long-time standby, energy-conservation is very tangible.
