Solar water heaters bring us great convenience, no need for electric heating, solar energy can be used, and the capacity is larger than the average water heater. The solar water heater market can be described as in full swing, then you know the solar water heater purchase considerations , below Renovation home decoration network Xiaobian simply talk about lifting the water heater purchase tips:
1, the liner
The inner tank of the solar water heater that is currently on the market is divided into two types: the stainless steel inner tank and the enamel inner tank. The stainless steel liner is divided into a bite and a welded liner according to the workmanship. The quality of the biting process is poor; the welding is easy to corrode, and the general life span is about 5 years. The enamel liner is divided into ordinary enamel, high-grade enamel, titanium sapphire enamel liner; ordinary enamel liner life is about two years. The high-grade enamel liner generally lasts for about 5 years.
2, heat preservation
The thickness and material of the water tank insulation layer are important parameters that affect the insulation capacity of the water tank. The water storage tank is the “hot water warehouse†of the water heater, and its performance is mainly reflected in the heat preservation effect. A good insulated water tank depends not only on the thickness of the insulation layer, but also on the insulation materials and processes.
3, the structure of the link
At present, there are two kinds of structural connections in the market, one is a silicone ring seal, and the other is a metal seal of a copper sleeve structure. The water heater sealed with a silicone ring is inconvenient to maintain and is prone to water leakage. The copper sleeve sealed solar water heater uses a double-walled heat pipe vacuum tube, which is subjected to high pressure, high temperature resistance, aging, and convenient to use.
4, the pipeline
Because the water heater is often placed on the roof, there is a certain pressure in the house, the hot water temperature is high in summer (up to 90 °C), the outdoor environment temperature is low, etc., so it is best to use cross-linked pipe or aluminum-plastic composite pipe or reinforcement. plastic hose. It has the characteristics of pressure resistance, high temperature resistance, low temperature resistance, non-toxicity and tastelessness, small heat capacity, low heat loss and not easy to freeze in winter.
5, the brand
At present, there are more than 5,000 brands in the solar water heater industry. Consumers should choose large brands with high reputation in the country. The solar water heaters produced by big brands not only have reliable product quality, but also provide consumers with long-term after-sales service guarantee.
