Misunderstanding the hot water market, more and more varieties, choose what kind of a rational consumer. Now several major categories of solar water heaters, main function and adapt to geographical listed below, a reasonable choice, both to save money and chic.
☆ flat plate solar water heaters, water production, which will help to clean, high thermal efficiency is combined with the building product of choice. But not frost, when the ambient temperature of 0 ℃ not work, widely used in non-freezing region, more than 90 percent of the foreign user to use this product (flat-panel water heater through the transformation of the anti-cold).
☆ vacuum tube solar water heaters, high borosilicate glass vacuum tube invented by Yin Zhiqiang, Professor, mainly in China, with some frost ability, can work as usual in the environment of -15 ℃.
☆ heat pipe solar water heater vacuum tube solar collector with heat transfer catheter can, because of the increased heat transfer medium, the thermal efficiency of a certain loss. The advantages of pipe water, and never fouling, suitable for cold regions.
Of the three water heaters, both pressure and non pressure points. The pressure also tank and collector separation, the organic integration of solar water heaters and buildings. Pressure hot water pressure and water pressure equivalent to the bath more comfortable, non-pressure hot water water water pressure compared to the natural drop of water pressure per meter gap between the water pressure is 0.1kg. Pressurized higher than the cost of non-pressurized, the prices are naturally thin.
When you purchase, be sure to buy according to your region, housing appearance and need to determine what species, what size water heater, change the following misconceptions:
A heat pipe vacuum tube solar air conditioner is a new generation of products. Some companies starting their own economic interests Branch blind propaganda. Plate and vacuum tube collectors are the different types of two products, there is no first generations Overall, the thermal efficiency of the tablet and with the buildings the combination of better than a vacuum tube. Antifreeze solar water heater with a broader market.
2, the higher the price, the better the quality. Select water heater is recommended to determine the right products, not to what species the highest price on what to buy. For example, a friend of Guangzhou to buy sets of heat pipe solar water heater, the price is almost twice that of the vacuum tube water heater with specifications, three times that of the flat plate solar water heater, in fact, the kinds of waste. Because of the heat pipe is developed for anti-cold, thermal efficiency is also nearly flat, vacuum tube water heater. Of course, if you need the pressure to use the heat pipe is another matter. Non-freezing region the use of plate or vacuum tube water heater to fully meet the need.
3, pipe the bigger the better. Solar water heater collector effectiveness and quality and the size of the tube does not contact. On the contrary, the greater the tube is more likely to stay hot water pipe memory, a direct impact on the effective use of hot water. The daily water heater Nissan water tank capacity is limited.
4, the water heater the same size. Solar water heaters, water production is fixed, it directly affects the size effect of energy saving, safety. In other words, solar water heaters must have adequate water for family needs. Solar hot water tank insulation of the day, ever use hot water can be used the next day, if the next day, rainy days, the amount of conventional energy is much less, it reached more to save money. So, what criteria determine the specifications of the water heater you need it? Guangdong, for example, it is recommended that this standard: use the shower, per person water ≥ 50kg, if the bathtub, 150kg / cylinder. Reached the total amount of water to adapt to the water heater specifications. If your house is a villa or special requests, please commissioned by manufacturers in particular production, in order to get the greatest degree of aesthetics and applicable.
