The invention relates to a 
solar water heater and building integrated scheme, i.e., the 
solar water heater and the outside structure of a building are organically integrated into a whole. In the past, 
solar water heater and 
building integration is undesirable, the called solar 
water heater and 
building integration actually means simple arrangement of solar 
water heater members on the building. In some cases, a heat collector is stuck to a balustrade, as the heat collector is put vertically, not only has the heat collector short heat 
collection time, but also the space cannot be utilized effectively, as a result, the effective installation area of the heat collector is small. After practical investigation and research, the heat collection efficiency of the heat collector is poor, in some cases, the heat collector is simply arranged on the building, hazards exist, the heat collector can injury passers-by in case of falling-off after being damaged, besides, arranging a water tank of the 
water heater indoors not only occupies indoor space, but also influences indoor outlook. In order to solve the problems, the solar water heater and building integrated scheme is designed. The scheme is characterized in that the heat collector and the water tank of the solar water heater, various water pipes connected with the water tank, heating cables, intelligent 
system cables and the like are arranged in an upper balcony and a lower balcony extended from the outer wall of the building to form an integrated structure. The balconies are formed by 
casting reinforced concretes. When the scheme is applied to old buildings, the balconies are made of steel frames or 
steel frame platforms. The scheme can be correspondingly applied to each floor in the same building. The scheme and the building structure are organically integrated, not only is the practicality high, but also the building style is kept unchanged, so that the installation effect is beautiful and unique.
