Q:Solar water heater is really easy to bad
Vacuum tube.Vacuum tube is the core component of solar water heater, but also the heart of the solar water heater. The performance of the vacuum tube is affected by the coating technology, such as cleaning, coating, vacuum pumping, sealing and so on. But some super low vacuum tube using the solar water heater has the following defects: low vacuum, only quality products 1/100 tube residual impurities and water vapor, a high temperatures encountered into gas, vacuum reduction; low vacuum film stability of two or three years, intimal layer aging, fall off, resulting in the thermal performance decays rapidly, unable to absorb enough heat
Q:Solar water heater can be used in winter
And this is a concern for many people, if not the use of solar energy in winter that means the utilization rate of solar energy is only half, this will greatly increase the cost of installation of solar water heaters, forcing consumers to choose other water heater system. In fact, the solar water heater technology now, the use of solar energy in winter is not a problem, as long as the snowstorm raging will not stop working, solar energy, free life hot water for our time.
Q:What is the meaning of water on the solar water heater
Only cold water, hot water does not, first check the instrument to show how much is the water level, whether there is water, such as the display of water, the hot water pipe in the air is blocked, the water to shower, and then open the water valve and let water directly into the hot water pipe for one to two minutes, immediately OK.
Q:Solar water heater inside the scale how to clean it?
1, water temperature for a long time to maintain above 70 degrees;2, the water is relatively static state.The composition or composition of the scale is complex, usually not a single compound, but a chemical composition, and contains other chemical components. According to the chemical composition of the scale, generally can be divided into several kinds of carbonate, silicate sulfate scale scale, scale, scale, scale, mixed oil and iron oxide scale and dirt etc..The scale is a poor thermal conductivity material, will hinder the transfer of heat, the water heater is not uniformly heated, causing local overheating, or partial pressure, eventually damage the water heater, even in danger.
Q:Classification of solar water heaters
2) flat plate solar water heaterFlat plate solar water heater can be divided into tube plate, wing tube, snake tube, flat box, round tube and heat pipe type. The utility model has the advantages of good integrity, long service life, less failure, safety, low pressure operation, safe and reliable, easy to heat absorption area, combined with the construction, resistance to water and air drying advantages, its thermal performance is stable. Because of the non vacuum in the cover plate, the insulation performance is poor, so the collector performance is poor when the ambient temperature is low. Low temperature or high water temperature required for low thermal efficiency. Such as the need to replace the whole set of frozen hot plate, suitable for the southern region of the winter is not frozen.
Q:How to deal with the solar water heater hot water pipe
Treatment method:1, if there is a thermostat trip problem, the general point of the electric water heater has a dual thermostat, that is, room temperature control and temperature control
Q:Solar water heaters are still required to install the check valve accessories
Generally do not need. Check valve is to prevent the return of hot water to the tap water pipe, so hot pipe.If you can not rest assured that one can not spend a few money, a peace of mind.Now the water mixer which will have a check ball.
Q:What is the structure and principle of solar water heater?
Two is the surface absorption coating. The core fin efficiency of the designed collector should be more than 93%. The core fin efficiency of the collector is related to the structure of the core, the surface treatment and the overall structure of the collector. The overall heat transfer coefficient of the collector can be described by the total heat transfer coefficient, which is the same as the size of the geometry. That is to say, in the case of the same efficiency, the heat collector can be thinner. Selective absorbing surface can improve the efficiency of heat collection, but these products in the market in order to improve economic efficiency, often thin rib. In the case of water heaters, the actual effect of the collection of such products and the selection of some poor (and even no selectivity) but the thickness of some of the collector will not be much difference.
Q:Solar energy or electric water heater for domestic hot water
Solar water heater with auxiliary electric heater is recommended in the case of solar water heater installation.
Q:What can replace the solar water heater
Air energy heat pump water heater! Air energy water heater mainly to the air to heat, with solar water heater energy saving, environmental protection, safety advantages, but also solve the problem of the solar water heater air heater can rely on the sun heat and installation inconvenience. The air heater to heat the heat exchange through the media, does not need the electric heating element in contact with water, there is no danger of leakage of the electric water heater, gas water heater also eliminates the risk of poisoning and explosions, but no fuel heater exhaust emissions caused by air pollution.
