The performance of a domestic solar water heater has volatility and intermittency with the period of solar energy supply. In continuous rainy days or at night, the water storage capacity of the household water heater cannot fully meet the requirement of household hot water. On the other hand, a regional central heating system is generally adopted in towns in northern China. In a centralized heating system, the return water temperature of a secondary heat supply network is generally between 40 and 60 ℃, and the system is very suitable for being combined with a heat pump to improve the temperature of domestic hot water. The solar energy heat supply is combined with the heat pump and the heat supply network backwater, so that the hot water heat supply temperature when the solar energy fluctuates or is insufficient can be ensured on the basis of utilizing the solar energy, and meanwhile, the backwater temperature of the heat supply network is reduced, and the heat supply economical efficiency is improved.

Meanwhile, the solar water heater works at normal temperature, the water temperature is 15-100 ℃, the water temperature cannot reach more than 100 ℃, the aim of civil hot water can be achieved, and the standard of the vaporized water industry cannot be achieved.

1. The operation is carried out under normal pressure. The existing solar vacuum tube can not work normally under the condition of pressure, and basically performs normal heat and cold exchange circulation under the normal pressure state.

2. An accessory. The existing solar fittings basically belong to light low-temperature materials, cannot be constructed in a large scale, cannot achieve steam energy generation and large-scale heat generation, and therefore cannot be industrially produced.

3. The reserve energy is insufficient. The normal temperature medium water is stored in the heat preservation water tank at 85-100 ℃, basically under normal temperature and normal pressure, and the storage time is basically not more than 24 hours.
