What kind of water heater do you use?
Wanhe Group 1993 was established in Guangdong, which is a company based on? Gas appliance expert? Gas appliance professional manufacturing enterprise with brand positioning and domestic production scale. Wanhe started with technological innovation, and successively filled the domestic technical gap 14 times in gas appliance manufacturing field, and obtained more than 300 technical patents, becoming the leader in gas appliance industry. Its innovative products further consolidated the leading position of the brand.
What types of water heaters are there?
1. According to the types of gas, it can be divided into four types: artificial gas water heater, natural gas water heater, liquefied petroleum gas water heater and biogas water heater. Water heaters with different gas types cannot be used universally. According to the control mode of water outlet of water heater, it can be divided into front water heater and rear water heater. In the past, the water heater used the water inlet valve to control the hot water flow of the water heater, which was simple in structure, but inconvenient to use. The latter water heater uses the outlet valve of the water heater to control the hot water flow of the water heater. Its structure is complex, but it is easy to use.
Two, according to the water supply pressure can be divided into low pressure, medium pressure and high pressure water heaters. According to the exhaust mode of water heater, it can be divided into three types: straight water heater, flue water heater and balanced water heater. In-line water heater: The air required for combustion-supporting of in-line water heater is taken indoors, and the exhaust gas after combustion is directly discharged indoors, which is the worst safety. If the relevant state departments have banned production and sales, those in use should be eliminated and updated as soon as possible;
3. Flue-type water heater: The flue-type water heater is an improvement of the direct-row water heater, and an anti-reflux exhaust hood and a smoke exhaust system are added to the upper part of the original direct-row structure. The main feature of flue water heater is that the combustion flue gas is discharged to the outside through the flue, which solves the indoor air pollution problem to some extent. Compared with the direct smoke exhaust of in-line water heater, this is an improvement in safety technology of gas water heater. However, because the combustion-supporting air required by this water heater is still taken from indoor, the combustion intensity is low and the water heater is large, so there are still many safety hazards in the installation and use of the water heater. Therefore, from the perspective of ensuring user safety and environmental protection, flue water heaters will gradually withdraw from the market in the future. For example, the Shanghai market has long been banned.
4. Forced exhaust gas water heater: The main cause of safety accidents of gas water heaters is indoor air pollution. To avoid the accident of carbon monoxide poisoning in flue gas, the fundamental measure is to exhaust the flue gas to the outside and keep the indoor air clean and hygienic. Forced exhaust water heater uses forced exhaust or forced blast to exhaust the combustion smoke to the outside. Flue-type water heaters use natural exhaust gas to discharge smoke to the outside, which is better than direct-row water heaters in safety. However, flue water heaters have high requirements for flue installation conditions, which are difficult to meet in apartments in general cities. The safety performance of forced discharge water heater is more perfect and the installation is relatively simple. Forced-row water heaters have two typical structures: exhaust type and blast type.
The above tips introduce the question of what kind of water heater to use. You can choose the water heater of Wanhe Group, which is not only of good quality, but also of high brand positioning. It is a relatively large-scale enterprise in China, so you can learn more about it. What kinds of water heaters are there? For example, forced row water heaters and gas water heaters. , and compare and purchase according to actual needs.
