Anonymous users2024-01-24Disadvantages: 1. The cost is high, much more expensive than ordinary electric water heaters and gas water heaters, and it is not suitable for ordinary families.
2. Complex installation.
3. The utilization rate is not high, and the solar energy is enough in bad weather or winter.
Solar water heater is a heating device that converts sunlight energy into heat energy, heating water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, mainly vacuum tube solar water heaters, accounting for 95% of the domestic market share. Vacuum tube household solar water heater is composed of heat collector tube, water storage tank and bracket and other related spare parts, the conversion of solar energy into heat energy mainly relies on vacuum collector tube, vacuum collector tube uses the principle of hot water floating and cold water sinking, so that the water produces microcirculation and obtains the required hot water.

2. The water tank is relatively small, if one person uses hot water that can be used with solar energy, if a family can only use electricity to heat, the water tank is below 120 liters.
3. Regional restrictions are relatively strong, generally in the south and more practical, while in the north it is basically like chicken ribs.
4. If the weather is too cold, the antifreeze should be replenished or replaced regularly, which increases the after-sales cost.
5. The installation is complicated, but this is generally installed by workers.
6. The functional and practical efficiency of solar water heating is not very high.
Installation precautions.
1. Before installation, first select the installation location, determine that the installation location of the solar water heater is not a residential activity place, and the installation site meets the product requirements.
2. If there is a wall bracket or a part extending outside the wall, and it is facing the sun, the collector can be fixed on the top and reinforced with a stainless steel tripod and reinforced with an extended expansion nail, and the length trace should exceed the thickness of the wall.
3.If there is no wall bracket, the collector can be fixed to the wall with a stainless steel bracket on the sunny wall.
His theories and ideas are good, but in practice they are the same as water heaters, or even worse than water heaters, and I can only describe them as bad!! >>>More
