How to choose a natural gas water heater, how to choose a natural gas water heater

Q: How to choose a natural gas water heater.

Answer: The choice of gas water heater mainly depends on the following points.

1. Gas type;

When buying a gas water heater, you must first confirm what kind of gas is used in the home. If you use natural gas at home, then choose a water heater with the "T" logo when choosing a gas water heater, if you are using artificial gas at home, then choose a water heater with the "R" logo, and if you use liquefied gas at home, then choose a water heater with the "Y" logo.

2. The choice of liters;

Gas water heaters are distinguished by the number of liters, such as: 12L, 13L, 16L, etc., consumers should decide which gas water heater with a good number of liters to choose according to the household water consumption, so as to ensure normal water use.

3. Security;

Gas water heaters can be divided into four categories: in-line type, flue type, strong type and balanced type according to the exhaust method. The mainstream on the market is the strong exhaust type and the balanced type, the strong exhaust type is to forcibly discharge the exhaust gas generated by combustion outside, and the balanced type is to extract the outdoor air for combustion, and the exhaust gas is forced to be discharged outdoors, so these two are the safer of all gas water heaters.

4. Constant temperature effect;

There are three ways to keep the temperature of the gas water heater, which are the constant temperature of the gas proportional valve, the constant temperature of the water and gas double adjustment, and the constant temperature of the water servo, of which the water servo has the best constant temperature effect, followed by the double adjustment of water and gas, and finally the proportional valve of gas.

The method is as follows: 1. When purchasing natural gas water heaters, it is necessary to ensure that the gas consumption of the gas water heater is not greater than the flow rate of the gas meter at home.

2. The water output of the water heater per minute is large and small, so the water heater has 6 liters, 8 liters, 10 liters and other specifications. The high-flow water heater is suitable for families with a large population and no heating, if you live on the fifth floor or above, choose a gas water heater with low water pressure start;

3. When buying a natural gas water heater, consider whether the safety devices are complete and reliable, such as flameout protection, water overpressure protection, anti-dry burning safety protection, anti-freezing protection, etc.

Gas water heaters are widely used in many of our homes, and they can really achieve fast heating. When we are buying a gas water heater, it is very important to choose a high-quality water heater, the purchase of water heater is not blind, and it is necessary to master certain purchase tips. Next, I will teach you how to choose a gas water heater to let you cool off in the summer, let's take a look!

Method 1: Look at the air source.

For domestic gas water heaters, the gas source is the main factor that depends on its use. At present, the gas source of gas water heater mainly includes artificial gas and liquefied petroleum gas, but the two cannot be used universally, so when purchasing, we must pay attention to identify which form of gas source it is, and then purchase it in combination with the actual situation of the family.

Method 2: Exhaust gas exhaust device.

For water heaters, there are many potential safety hazards, and one of the key factors is the emission of exhaust gas. For the gas water heaters on the market, there are two main types of exhaust gas discharge devices: flue exhaust type and strong exhaust type. The flue discharge type is mainly connected to the exhaust port of the water heater through the exhaust pipe for exhaust gas discharge, so if the flue is not installed properly, it will lead to the danger of exhaust gas backfilling; The strong exhaust type mainly relies on the installation of a small fan on the water heater body, and the fan is started to discharge the exhaust gas through the linkage device of the water heater.

Method 3: Safe to use.

In fact, many times the incident of gas poisoning or fainting in the bathroom is caused by people not having a correct and safe use habit. Gas water heaters need to consume a lot of oxygen during use, so it is best not to use them continuously, and the installation should also be installed on the wall more than two meters away from the external wall or external window, not installed indoors, and pay attention to certain ventilation during use. Traces.

Method 4: After-sales service.

A very important consideration when buying a water heater should be after-sales service. Different from other household items, there are many potential safety hazards of gas water heaters, so they are generally handed over to professional masters for installation after purchase, so when purchasing water heaters, we must pay attention to how to compare the manufacturer's after-sales service, whether there is a maintenance point in the local area or a special maintenance department, so as to facilitate the maintenance when there is a problem in the future.

Gas water heater cleaning and maintenance.

1. When using gas water heater for cleaning and maintenance, you must read the product instruction manual, and use the water heater according to the instructions of the manual and nameplate, as well as carry out preliminary simple water heater repair, cleaning and maintenance, etc.;

2. The room must be well ventilated;

3. When the gas water heater has gas leakage, water leakage, flame does not extinguish after water stopping, poor combustion conditions, etc., it should be stopped from use, and the gas management department or the manufacturer should be notified in time to repair it, and it is strictly forbidden to disassemble and repair it without permission;

4. Regularly ask the professionals or manufacturers designated by the gas management department to clean and maintain the gas water heater, and timely overhaul to keep the gas water heater cleaning and maintenance can work well;
