Hot water consumption increasing and anti-scaling solar water heater

The utility model provides a hot water consumption increasing and anti-scaling solar water heater, comprising an insulation hot water tank, a vacuum thermal-collecting pipe connected with the insulation hot water tank, a water inlet main pipe arranged in the insulation hot water tank and water inlet branch pipes, wherein one end of each water inlet branch pipe is connected with the water inlet main pipe and the other end is arranged at the bottom of the vacuum thermal-collecting pipe. The hot water consumption increasing and anti-scaling solar water heater is characterized in that the distance between the water outlet of each water inlet branch pipe and the water inlet end of the water inlet main pipe is enlarged in sequence from near and far, and the water inlet end of the water inlet main pipe and a spare end respectively extend outside the box. Hot water in the vacuum thermal-collecting pipe can be forcibly extruded to the insulation hot water tank according to needs, thereby effectively increasing the hot
