I would like to recommend a patented product to you: the solar instant water heater automatic control center. This two-type water heater combined with the hot water supply automatic control device is specially designed for your situation.
When the solar water temperature reaches the set temperature, it goes directly to the water point. When it cannot reach the set temperature, the gas water heater automatically turns on for secondary heating. An external circulation pump can be connected, which has hot water circulation function, low-temperature antifreeze function and anti-lock self-protection function, which avoids the disadvantages of frequent startup of gas water heaters caused by using traditional hot water circulators, prolongs the service life of gas water heaters, and has intelligent control and convenience , comfort and energy saving advantages. Introduction to the intelligent control functions of the solar instantaneous water heater automatic control center
In order to solve the above-mentioned problems, Hefei Hengnuan HVAC Equipment Co., Ltd. invented the "solar instantaneous water heater automatic control center". This automatic control device enables users to intelligently switch between solar water heaters and instant water heaters (gas water heaters, gas wall-mounted boilers or instant electric water heaters, etc.) based on the comparison between the set water temperature and the actual water temperature when using hot water. When the water temperature reaches the set temperature, the instant water heater does not turn on. When the solar water outlet temperature does not reach the set temperature, the instant water heater automatically turns on. At this time, the water flowing out of the solar water heater is reheated by the instant water heater. This is both energy-saving and very convenient, eliminating the need for manual operations.

These two kinds of water heaters cooperate with the hot water supply automatic control device, and one kind of water heater As a common water heater, the other is a supplementary water heater. Commonly used water heaters are very energy-saving water heaters, such as solar water heaters and air-energy water heaters that can be heated at peak and valley electricity prices. They are generally volumetric water heaters, and supplementary water heaters are commonly used water heaters. It is an infrequently used water heater that is turned on urgently when the water volume or temperature is insufficient, but it can be quickly heated when needed. Therefore, an instant water heater is generally used to supplement the water heater, such as a gas water heater, a gas wall-mounted boiler or an electric instant water heater.

Compared with traditional hot water circulators, the frequency of water heater starts is reduced and the service life of the water heater is extended.
The automatic control center controller has reserved wiring terminals for the hot water circulation pump, which can be connected to an external hot water circulation pump. In this way, the automatic control center can control the hot water circulation pump at the same time, and can start the hot water circulation at a fixed time and temperature, thus Each water point will have hot water immediately, without wasting cold water, reducing waiting time, making it convenient, comfortable and energy-saving.
The solar water tank or air energy water tank in this hot water system becomes a water storage buffer tank. When the outlet water temperature of the water tank is higher than or equal to the set water temperature, the water flow will not pass through the supplementary water heater and flow directly. to the water point, so that the supplementary water heater will not start. Only when the water tank outlet temperature is lower than the set water temperature, the water flow will be reheated through the supplementary water heater, and then return to the water point. Compared with the hot water circulator (pump) usually sold in the market, as soon as the hot water circulator (pump) is turned on, the hot water must flow through the water heater and the water heater is turned on simultaneously. This greatly reduces the frequency of starting and stopping the supplementary water heater and greatly extends the service life of the water heater.

When used as a hot water circulator, it also has the timing and temperature intelligence of the automatic control center. Control function
When used as a hot water circulator, it can be programmed to turn on and off at a scheduled time, so that it does not circulate when hot water is not needed, and then automatically turns on the hot water circulation when hot water is needed. This achieves both Maximum energy saving, while improving water comfort, and extending the service life of the automatic control center and circulation pump. The automatic control center also has low-temperature antifreeze function.
Under the premise that the hot water system is designed as a hot water circulation system (the hot water system is made into a loop and the automatic control center is equipped with a hot water circulation pump), when the water level is lower than 5℃, the automatic control center automatically Turn on the low temperature protection function. At this time, the three-way valve and water pump will be opened as needed; when the water temperature reaches 15°C, the valve and water pump will be closed to ensure that the home hot water system will not freeze due to freezing. Note: To ensure that this function works, you must ensure that the power supply and gas of the gas or electric water heater are connected and working properly.

When the automatic control center does not work again within 24 hours after it stops working, the three-way valve and The circulation pump will automatically work for 40 seconds to prevent the three-way valve or the circulation pump from adhering and locking. The automatic control center has obtained national patent certification
The automatic control center has obtained the utility model patent certificate issued by the State Intellectual Property Office of the People's Republic of China, patent number: ZL 2011 2 0315628.2
The invention of this solar instant water heater automatic control center allows users to enjoy free solar hot water, and can intelligently switch to secondary heating when the water temperature is not enough. It also has hot water circulation function, anti-freeze function and anti-lock function. It has unique functions, intelligent timing and temperature control, and greatly extends the service life of the instant water heater. It is a very good invention.
