Point one It is to buy a water heater that matches the type of gas used in your home. Consumers need to find out what kind of gas source your home uses. Point two Is the location. Because the temperature difference between the north and the south and the bathing habits are different, you should pay attention when choosing. In addition to the striker can work continuously for 60 minutes without stopping the other brands will shut down automatically in 20 minutes. The name is to prevent poisoning. In fact, the heat exchangers in these factories are relatively thin. If burning for a long time will cause burn-through and water leakage, it will take 20 minutes to stop the cooling heat exchange. Of course, if you are in the South, you may choose another water heater because the temperature difference may take less than 20 minutes. Please go to the official website of the relevant factory to find the specific parameters. Point three It is the purchase of capacity. Generally, the number of liters of 8 liters, 10 liters or more above the water heater refers to the amount of water per minute when the water is heated by the water heater, and the inlet water temperature and the outlet water temperature are raised by 25 ° C. So isn't the higher the number, the better? This depends mainly on what you need. The average shower is 8 liters - 10 liters. If you need to wash the surf bath and soak the bathtub, you should choose more than 10 liters. Point four It is the purchase of the price. The same brand of water heater, the higher the number of liters, the higher the price. At the same time, the higher the safety factor, the higher the price, which is roughly in the form of flue-type, strong-discharge, balanced, and forced-distribution. Point five It is to buy a water heater that meets the requirements of your housing construction. Since various types of gas water heaters have different requirements for installation, consumers must pay attention to their choices. For example, flue-type water heaters must not be installed in the bathroom, and can be installed in a well-ventilated kitchen, but must be installed. The flue is discharged to the waste fumes outside. Because it is easy to install, it is suitable for general buildings, but its wind resistance is poor, so high-rise houses are not suitable for installation. The balanced forced (to) row type has strong wind resistance, higher safety performance, and a wider range of installation and application. Point six Technical clearance, after-sales guarantee. The best way to learn about a machine is to check their reviews and the history of this brand online. The long-established description of technology has not passed away in the economic tide, so the quality problems can be solved quickly in the later period, and there is no need to fear that the things bought will be repaired. laser tape meter Xi'an Lonn M&E Equipment Co., Ltd. , https://www.smartmeasurer.com
