Water heater purchase tips: must avoid these pits
An autumn rain pulled the temperature back to around 20 °C. Going home to eat something after work, and then taking a hot bath is the most pleasant thing. However, a safe and easy to use water heater is especially important.
The water heaters on the market can be very selective, electric water heaters, gas water heaters, air energy water heaters and solar water heaters. On the one hand, solar water heaters have poor water storage problems and poor experience, eliminating the choice of domestic water heaters.
Electric water heaters are also popular in recent years. They can be installed and used without considering the gas pipeline problem. However, the aging of equipment is extremely prone to electric shock accidents, and energy consumption has always been criticized by consumers. The rise of air energy water heaters is regarded as the future development of water heaters. Trend, but due to process technology bottlenecks, the cost is too high.
The advantages of gas water heaters are obvious, the power is high, the water output is large, there is no need to wait when it is opened, the continuous hot water can be provided, and the use cost is relatively low. With the continuous improvement of the process, consumers are most worried about the problem of carbon monoxide poisoning. Solved, gas water heaters are a good choice.
Gas water heaters are roughly classified into straight row, flue type, balanced type and strong row type according to the mainstream discharge mode. Among them, the straight-row type and the flue type have been rectified and removed due to safety issues.
Balanced water heater
The oxygen required for the combustion of the balanced gas water heater is taken from the outside, and the generated exhaust gas is also discharged to the outside through the duct to avoid the consumption of indoor oxygen during combustion, and the occurrence of oxygen deficiency, thereby greatly improving the safety and reliability of the combustion water heater.
The balanced gas water heater adopts a unique device, one pipe is used to extract outdoor oxygen, and the other pipe is used for exhausting. The whole process does not consume indoor air at all, nor does it cause smoke to pollute the indoor environment. Compared with the traditional exhaust flue water heater, its thermal efficiency can also be improved, which can save energy and improve safety performance.
Strong row water heater
The mainstream gas water heaters in the market are still strong. The strong row type adds a flue gas motor to the ordinary water heater, and exhausts the exhaust gas to the outside through the flue; during operation, the flue gas is forcibly discharged to the outside through the flue, but the oxygen required for combustion is still taken from indoor.
At the same time, the strong row is subdivided into an exhaust type and a blast type.
The exhaust type is forced to discharge the high-temperature flue gas to the outside through the exhaust device, and the blower type uses the blower to take in air from the chamber, and pressurizes it to the sealed combustion chamber, and the burned flue gas is forced to be discharged after being cooled by the heat exchanger. Outdoor, the current market for strong-discharged water heaters is mostly blast-type, but the problem of carbon monoxide is still difficult to avoid.
Choosing a burning water heater, in addition to choosing the right way to exhaust and look for the brand, there are still many aspects to pay attention to.
1. Consider the type of gas. At present, China's gas has three kinds of natural gas, liquefied petroleum gas and artificial gas. The choice of gas water heater must be based on the characteristics of the gas source to select the appropriate water heater, recognize the mark: artificial gas JSR, liquefaction LPG JSY, natural gas JST, to prevent mistakes.
2. If consumers are using centralized gas supply from the building, they must ensure that the gas consumption of the gas water heater is not greater than the flow rate of the gas meter; consumers using liquefied petroleum gas should be equipped with corresponding pressure reducing valves to avoid gas supply. Insufficient pressure can not fully utilize the efficiency of the water heater.
3. To purchase gas water heaters, it is important to consider whether the safety devices are complete and reliable, such as flameout protection, water overpressure protection, anti-dry safety protection, antifreeze protection, and whether high-precision electronic water temperature and water flow sensors are also important. Determine the heat exchange efficiency of the water heater and the length of life.
After the upgrade of straight-line, flue-type and strong-discharge type, the safety of gas water heaters has been greatly improved. Some products also claim to have the function of preventing carbon monoxide poisoning, but in fact, they cannot effectively eliminate the problem of excessive CO. If you just want to change a gas water heater, the first choice is to look for big brands, the brand's popularity is often the guarantee of quality.
Choosing a gas water heater is very simple, that is, it is safe and easy to use. Please check the water heater at home for safety hazards and quickly replace it.

Anti-cursor belt, also known as pre-shaped road anti-cursor belt, is a new type of reflective material made of a combination of high-molecular flexible polymers, pigments and glass beads.
Anti-cursor bands are mainly used for highway pavement indications: such as zebra crossing, center double solid line, lane dividing line, text, arrows, etc. Suitable for asphalt, cement, concrete, marble and other pavements and walls.
The main feature of the anti-cursor belt is that it is pre-formed, and the product substrate and surface have glass beads, which have good reflective and non-slip properties. The colors are bright and never fade.
The types of anti-cursor tapes can be divided into: engineering anti-cursor tapes, engineering anti-smudge tapes, temporary anti-cursor tapes, and temporary anti-smudge tapes.
Uses: Directional signs; prohibition signs, warning signs and indication signs, and signs used on ground advertising.
Life: According to road conditions, traffic flow and installation, the service life can be at least 2 years.
Engineering Grade Cursor Belt
Both the substrate and the surface of this tape have glass microbeads, which have the effect of reflecting light and sliding. Generally, there are two types: ordinary type and self-adhesive type. It is suitable for the production of various markings, arrows, text, patterns, colored ground signs, colored three-dimensional signs, pipeline signs, self-adhesive parking plates, and ground advertising.
Construction requirements: construction is simple and fast. The construction road must be clean, dry and level. Use in an environment where the air temperature is not lower than 5 ° C and the ground temperature is not lower than 10 ° C.
Engineering anti-fouling tape
The surface of this tape has been treated with a special process. The surface does not have glass beads and is smooth and flat. It has a good self-cleaning effect. Generally there are two types: ordinary type and adhesive type.
Especially in supermarkets, factories, squares and other places with high requirements for cleanliness.
