Can we install a solar water heater on the balcony?
Advantages of wall-mounted solar energy on a balcony
1. Wall-mounted solar energy for balconies Équishort of a pressurized water tank, this water tank can be connected to tap water. There will be no problems such as traditional solar water supply and the water pressure is guaranteed.
2. The balcony wall-mounted solar energy adopts the thermal cycle method, so even if the weather is as cold as minus 30° in winter, there will be no freezing phenomenon. , and the security performance of the system is relatively high.
3. The installation location is convenient. Even if it is installed on the first floor or ground floor, it can supply water to high-rise buildings without any external power devices.
4. Photoelectricity can be used together even if there is no sunshine. Electric energy heating can enjoy hot water in winter when there is no sunshine.
Wall mounted solar water heater is better vertically or horizontally ?
The wall-mounted solar water heater on a balcony is suitable for families benefiting from sufficient sunshine. It requires continuous sunlight. 5 days a day or more, no light blocked in winter and the best collector direction is 15 degrees west. In the Northeast, it is best to use wall-mounted solar water heaters that have a thermally conductive backing. Wall-mounted solar water heaters are generally both photoelectric and photovoltaic, and can be plugged in as a supplement in winter or when the weather is bad.
If the dual-use solar electric water heater bucket is installed on the balcony, can it be moved to the bathroom?
C It is more convenient to install a vertical solar water tank.
Vertical water tanks have high installation requirements and ensure that the hottest water is used, which is conducive to collection and collection.heat circulation; Vertical hot water tanks have good hot water temperature stratification and use the top. water supply. The cost of horizontal water tanks is lower, but the height of the water tank is limited and the mixing of hot and cold water is serious. The specific choice depends on the space and usage needs of your room.
There are two types of wall-mounted solar water heaters. The water tank is placed on the balcony, and the collector is placed on the balcony of the south facade of the building. The other is a sensual solar water heater with integrated heat storage and collection.
Operating principle
The hot water system is as follows: the fins inside the flat collector convert the absorbed solar radiation into energy thermal, allowing the sensor to exchange heat The temperature of the working fluid in the tube continues to increaselie. Taking advantage of the characteristics of low density of hot liquid and high density of cold liquid, cold water flows from top to bottom and hot water flows from bottom to top between the collector. and the water tank through the circulation pipeline of natural cycles.
Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be maintained at minus 40 degrees without freezing. So even in alpine and cold areas it can operate normally all year round.

According to your description, it should be a solar handle mounted on a pressurized balcony. wall. If this product is It cannot be moved into the bathroom, because this product mainly relies on the natural circulation of fluid between the collector and the water tank to gradually heat the water in the water tank. There are height difference and pipe requirements. length requirements in between. If it is changed to For the bathroom, it is estimated that a pump with a large lift will need to be added.
