Is there no point in using traditional water tanks for domestic solar water supply?

No need.

1. Home solar water supply breaks the traditional method of storing water in water tanks. The combination of new materials and new technologies makes solar water heaters bid farewell to the era of “traditional water tanks”. Therefore, traditional water tanks for domestic solar water supply are no longer necessary.

2. Industry experts analyze that the solar water heater after "removing the water tank" can be regarded as the beginning of a new product, which may trigger a new revolution in the solar water heater industry .

A very good idea. At present, your idea has been realized. The wall-mounted solar water heater for balconies is the prototype of your idea. be ordinary The feasibility of installing solar panels on ordinary electric heaters is almost zero.

Due to their relatively large power, ordinary electric water heaters consume a lot of energy. Solar water heaters can directly use sunlight to heat water without consuming electricity. They are green and environmentally friendly, and the sunlight is inexhaustible. However, the effect of using solar energy is not good in cloudy and rainy days. Installing these two types of water heaters separately in a house obviously takes up more space and generates more waste. And it would be great if these two devices could be merged, that is, a solar collector plate could be installed on a regular electric water heater, in order to combine the advantages of both and avoid the disadvantages.

In real life, there is indeed a similar product, namely the wall-mounted solar water heater for balconies. Let's take a look at the sola water heaterire wall mount for balcony and see how it adds a solar collector panel to a regular electric water heater.

General balcony wall-mounted solar water heater is composed of three main parts: solar heat collector panels, heat pipes and tanks water storage.

The main function of solar collector panels is to collect thermal energy from sunlight, which is the same function as our ordinary solar water heater collector panels.

The heat conductive pipes are two pipes connecting the solar heat collector panels and the water storage tank. They contain a heat-conducting fluid (propylene glycol) inside. The function of heat-conducting pipes is to conduct. the heat generated by the solar heat collector panels towards the tankr water storage (heat exchanger).

Water storage tank, balcony wall-mounted solar water storage tank Apart from the above two parts, it is basically an electric water storage water heater . But now, its electric heating part is called electric auxiliary heating, and its main heating is solar energy. It can be seen that one function of the water storage tank is to store water and the other function is to heat, whether it is electric heating or solar heating.

Working principle: The solar collector panel is first exposed to sunlight, and the collector panel heats the heat-conducting medium inside the panel. After being heated, the heat-conducting medium. As the density decreases, gravity will move along the heat-conducting pipes upward into the water storage tank. Youy heat conductive media circulating in the water storage tank can be considered as heat exchange. These higher temperature heat conductive media heat the cold water in the water storage tank. After the heat-conducting medium transfers temperature and becomes cold, it will then enter the heat-collecting plate along the descending heat-conducting pipe, where it will enter. be heated again and exchange heat. In this way, the water in the water storage tank is heated. This is the operating principle of the wall-mounted solar water heater for balconies which uses solar energy for heating.

When the sun is not good, you can start the electric auxiliary heating. It works on the same principle as an ordinary electric water heater, that is, the electric heating pipe directly heats the water in the water storage. reservoir.

Hellors why can't solar panels be installed on regular electric water heaters? The reasons are as follows:

1. Ordinary solar collector panels cannot be filled with thermally conductive media and thermally conductive tubes to form a circulation pipeline that continuously directs heat to the storage tank of water to heat the water.

2. The water storage tank of an ordinary electric water heater does not have a heat exchanger, nor is there a place to install a heat pipe.

For the two reasons above, even though we have heat pipes and heat transfer fluids, we cannot connect two devices that are not designed together. Therefore, if your friend wants to enjoy the benefits and functions of these two water heaters, you can buy this balcony wall-mounted solar water heater.

I hope my answer can be helpful to you! I am aAquarius homebody, welcome your attention!
