Stainless steel. The interior of the solar water heater insulation barrel is mainly composed of insulation materials and outer packaging. Insulating materials are polyurethane foam or polystyrene foam materials, which have good insulation effects and can effectively reduce heat loss. Solar energy is a renewable energy source that uses thermal radiation from the sun to produce photothermal conversion or photoelectric conversion. There are two main methods: photothermal conversion and photoelectric conversion.
There are two types of water leakage from the solar water heater storage barrel:
1. Water leaking from the joints between the vacuum tube and the barrel body.
Solution: Replace the sealing ring.
2. The cannon is leaking.
This has virtually no maintenance value. The structure of the barrel itself is double-layered. The inner layer isa water storage barrel and the outer layer is a shell. Insulating materials are added between the two layers using foaming technology. If you want to repair, the foam insulation must be destroyed, and the walls of water storage barrels are relatively thin and difficult to weld and repair. After repair, the insulating material must be filled. So the maintenance value of this is not great. Fixing it may not save you much money compared to buying a new one.
Solution: Replace barrel or replace solar.
Detailed information:
The solar water storage barrel is a container for store hot water. The hot water collected by the collector tube should be stored in an insulated water tank to avoid heat loss. The capacity of a solar water heater refers to the capacity of water that can be usedin the water heater, excluding the capacity which cannot be used in the vacuum tube. For pressurized solar water heaters, its capacity refers to the capacity of the medium in which heat exchange can take place.
The insulated water tank of a solar water heater is composed of three parts: an inner tank, an insulating layer and a water tank shell.
The water tank liner is an important part of hot water storage, and the strength and corrosion resistance of its materials are crucial. There are stainless steel, enamel and other materials on the market. The quality of the insulation material of the insulation layer is directly related to the insulation effect, which is particularly important in the cold season. The best insulation method is overall insulation by polyurethane foaming. The hull is generally made of colored steel sheet, galvanized sheet or sheet metal.e of stainless steel.
The insulated water tank requires good insulation effect, corrosion resistance and clean water quality.
