The utility model discloses a roof solar water heating system which comprises a flat-plate solar collector, an air source heat pump unit, a heat pump heating circulating water pump, a pipeline system and a heat preservation water tank. The flat-plate solar heat collectors are fixed on a roof foundation through a support, the flat-plate solar heat collectors are arranged in multiple rows and are connected in series through heat collector water pipes, and the two ends of each flat-plate solar heat collector are connected to the heat preservation water tank. The air source heat pump unit and the heat pump heating circulating water pump are connected to the heat preservation water tank through a circulating water pipe. The cold water supply pipe supplements cold water to the heat preservation water tank, the hot water supply pipe conveys hot water in the heat preservation water tank to all water consumption ports, and the hot water return pipe recovers unused hot water to the heat preservation water tank. The solar water heater can solve the problems that the water temperature of the solar water heater rises slowly and is unstable, residual hot water cannot be effectively utilized, and energy is wasted due to electric heating in cloudy and rainy days.

The utility model relates to an electric heating heat preservation device which comprises an inner container, a heating assembly and a shell. The inner container is used for containing liquid to be heated and insulated, an opening is formed in the top of the inner container, and the heating assembly is arranged on the outer wall of the bottom of the inner container. The heating assembly is connected with a conductive assembly, and the conductive assembly extends to the outside of the electric heating heat preservation device and is used for being connected with a power source. A first vacuum cavity is formed below the bottom of the inner container, and the heating assembly is contained in the first vacuum cavity. The shell is arranged on the outer side of the inner container in a sleeving mode, gaps are reserved between the shell and the inner container and between the shell and the first vacuum cavity, and the gaps form a second vacuum cavity. The three-layer and double-vacuum structure at the lower end of the device can effectively prevent heat generated by the heating assembly from being conducted through the side wall, the risk that a user is scalded due to the fact that the shell is overheated due to long-time heating is avoided, meanwhile, a better heat preservation function is achieved, and heat loss is reduced.
