As a kind of improvement of the present utility model, be provided with water tank on the support below condenser, high-temperature heat-collection pipe is connected with water tank with water return outlet by its hot water mouth.

As another kind of improvement the of the present utility model, high-temperature heat-collection pipe is connected with the pipeline of heating system with water return outlet by its hot water mouth.

The utility model advantage compared with prior art:

It mainly is the temperature height of solar energy heating.The utility model is a kind of complex focusing type heat collector, by multiple-point focusing the light and heat energy of the sun is carried out the high magnification compression, and its temperature generally can reach 600～1000 degree.And tracking heat collection automatically, can obtain the energy of regular solar water heater several times and even tens of times every day, both can be used as solar boiler, solar steam generator, also can be used as solar space heating facility and use.Be a kind of purposes very widely, the helioplant of environmental protection, development prospect is very extensive.

Next is reasonable in design, and is simple in structure, easy to process.Promptly can be mass-produced with the manual processing of mould, cost of manufacture is very cheap, is below 1/5th of common water heater price.
