Described inlet and outlet pipe is provided with the first solenoid electric valve, and described cold water pipeline is provided with the second solenoid electric valve, and described connecting pipeline is provided with the 3rd solenoid electric valve, and each solenoid electric valve telecom-connects by controller and controls its switch motion with controller respectively.
Described solar thermal collector is vacuum tube solar heating element or flat-plate solar collector or other solar thermal collectors.
Described metal coil pipe is pressure-bearing bellows or pressure-bearing pipe.
Also be provided with electrical auxiliary heater in described attemperater, this electrical auxiliary heater and controller telecom-connect by controller and control its work.
Also be provided with water level, cooling-water temperature sensor in described attemperater, this water level, cooling-water temperature sensor and controller telecom-connect and by controller instant playback water level, water temperature.
Also be provided with an exhaust overflow pipe in described attemperater, the top in attemperater is stretched in the upper end of this exhaust overflow pipe, and stretch out from the bottom of attemperater the lower end of exhaust overflow pipe.
Described controller be provided with LCDs, for the upper water key of controlling the first solenoid electric valve, for the artesian water key of controlling the second solenoid electric valve and the 3rd solenoid electric valve one open-one close, for control the electrical auxiliary heater duty add hot key and for controlling the insulation key of pipeline anti-freezing and heat-insulating.
The utility model, owing to having adopted above technical scheme, has following advantage and disadvantage:
(1) multi-functional, easy to operate: the utility model can realize having unlimited (non-pressure) in same water heater simultaneously, two kinds of pressure-bearings are used water function, and easy to operate, as long as but click just auto-conversion function of key.
(2) pressure-bearing function water cleaning: the utility model artesian water is the fresh water flow through in the hot water indirect metal coil pipe by attemperater, so water quality is fresh, health, exempts from secondary pollution.
(3) low cost of manufacture: compare with traditional solar water heater with pressure-bearing function, because using metal tube, replace expensive enamel, the stainless steel press-bearing water tank of cost, cost reduces greatly.
(4) dependability is good, and the life-span is long: the solar water heater that has the pressure-bearing function with tradition is compared, and because using the pressure-bearing metal coil pipe, replaces press-bearing water tank, and water tank burst porcelain, sealing-off phenomenon can not occur, and dependability is good, and the life-span is longer.
