The invention belongs to the technical field of polyurethane, and particularly relates to polyurethane combined polyester of a water storage type electric water heater and a preparation method and application thereof. The combined polyester consists of a component A and a component B according to a mass ratio of 1:(1 to 1.3), wherein the component A is prepared from the following raw materials in percentage by mass: 21 to 27% of polyether polyol I, 11 to 22% of polyether polyol II, 10 to 15% of polyether polyol III, 7 to 15% of polyether polyol IV, 15 to 20% of polyester polyol, 1 to 1.5% of foam stabilizer, 13 to 15% of foamer, 2 to 3% of catalyst, and 0.5 to 2.0% of water; the component B is polymethylene polyphenyl isocyanate. The combined polyester product has the advantages that the destruction to an ozone sphere is avoided, the environment-friendly property is excellent, the preparation method is simple, the prepared polyurethane foam has a low heat conduction coefficient, the sealing property is good, the strength is high, and the water absorbing rate and use stability are good.
