Wall-mounted boiler is one of the main heat source equipment for home heating, and it is also a popular equipment for home heating. The gas-fired wall-mounted heating stove first originated in Europe and has a history of hundreds of years. The full name of "wall-mounted stove" is: "gas-fired wall-mounted heating stove". Our national standard is called: "gas-fired wall-mounted rapid heating water heater", but it It is not a gas water heater in the traditional sense, which is essentially different from a water heater. Following small gas boiler works and analyze gas boiler purchase method for you.
Working principle of gas boiler
When the ignition switch of the boiler is in working state, the fan starts first to form a negative pressure difference in the combustion chamber. The air pressure switch sends the command to the water pump. After the water pump starts, the water flow switch sends the command to the high-pressure discharger. Gas proportional valve, gas proportional valve starts. Due to the existence of negative pressure in the combustion chamber, the natural gas does not have the imagination of combustion, so there is no deflagration imagination, quiet ignition and ultra-quiet, and also guarantees dangerous accidents. This standard can identify the stability of the furnace. Some customers are worried about the safety of gas because they do not understand the operation control principle of the wall-mounted boiler gas proportional valve. The gas proportional valve, air pressure switch and flue gas sensor switch are interlocked. The combustion chamber has a certain negative pressure gas proportional valve. Work, when the 5 seconds smoke sensor switch can not detect the exhaust gas, it will cut off the gas proportional valve to stop the gas supply, thus ensuring the safe use of gas.
This is the working principle of traditional wall-hung boilers. In fact, there is a condensing boiler, which is more energy-saving. The principle of condensing boilers is similar to that of standard boilers, but the condensing boilers have a set of heat recovery. System, let's take a look at the working principle of the condensing boiler.
The condensing gas-fired wall-hung boiler fully absorbs the sensible heat of the gas combustion products and the latent heat of water vapor through two heat exchangers. The calorific value of the gas refers to the heat released by the complete combustion of 1Nm3 gas. The calorific value is divided into high calorific value and low calorific value. The high calorific value refers to the heat released when the 1Nm3 fuel gas is completely combusted and its flue gas is cooled to the original temperature, and the water vapor is discharged in the state of condensed water; the low calorific value refers to 1Nm3 fuel gas After complete combustion, the flue gas is cooled to the original temperature, but the water vapor in the flue gas is still the heat released in the vapor state. It can be seen that the difference between the high heating value and low heating value of the gas is the latent heat of vaporization of water vapor.
Advantages of gas boiler
1. Set the heating time at will, and it can be turned on at any time.
Within a certain range, we can adjust the height of the indoor air at will. At the same time, the household gas boiler can not only provide hot water for our lives, but also save us space and money, not only save us the use of hot water, but also It has high security.
2. The energy used in the household gas boiler is natural gas or gas in the city. Every family can heat within 300 square meters.
3. A timer can be installed in the household gas boiler, we can set the start time before going out, and we can feel the warmth of the house when we get home.
4. Every family can establish a heating system by themselves, which will not only solve our heating problem, but also solve our hot water supply problem.
5. The charges are relatively reasonable. The gas consumption we use can be accurately counted. The amount of gas we use can be controlled by ourselves to save gas consumption.
6. Whether it is installed in the kitchen, basement or balcony of our house, it can be connected to the radiator through the wiring in the room, which can not only provide hot water but also achieve heating, and achieve both benefits.
7. After adding the indoor temperature controller in the room, we can adjust the different temperatures in our room. If there is no one in our room, we can lower the temperature a little, so as to ensure our circulating water or machine Will not be frozen.
How to choose a gas-fired boiler
1. Brand selection: Generally speaking, a good brand chooses safety, gas saving, worry saving, and service. When selling their products, manufacturers can talk about lotus flowers and promise everything, but not much can really do according to the promise. Because there is not enough capacity and financial resources to support after-sales service, nor can it guarantee the timely supply of accessories. Most users trust the imported boilers. The imported boilers must have customs reports. The manufacturers are required to provide raw material customs declarations, purchase invoices, and go to the relevant local authorities to identify whether they are genuine original imports. Keep your eyes open to see clearly. Avoid being fooled and wasting money! In addition, you must choose a boiler with a product insurance policy, and the manufacturer is responsible for the accident.
2. Power selection: The same brand has various power options. The selected power is large, which wastes funds and energy. The selected power is small, and the waste of capital and energy is small, but it does not meet the requirements for use. Take a look at the energy efficiency label of the wall-hung boiler. The best energy efficiency of the wall-hung boiler is the second-level product. Some wall-hung boilers can not reach the third level, and there is no energy efficiency label.
3. Choose according to your house area: Generally, the heating power required per square meter is about 120w-180w, and it varies according to the room type, structure, and building materials. Therefore, when you choose a heating stove, you should Ask the service provider's opinion first to see what kind of power your house is based on, and then measure a rough overall power. Recommend a formula to calculate the approximate power: the building area of ​​the house × 65% × 150w. Usually the heating area will be between 60% -70% of the construction area. If it is a 150 square meter apartment, its heating area will be between 90-105 square meters. We calculated according to the heating area of ​​100 square meters and expected to need 15kw of heating power, plus the daily domestic hot water demand, basically we must choose an 18kw heating stove.
4. Look at energy saving: Since the boiler is used throughout the winter, you need to pay special attention to the energy saving of the boiler. Choosing a boiler with good energy saving effect can not only reduce cost consumption, but also improve the quality of life.
5. Look at accessories: In order to achieve the most comfortable and convenient use effect, accessories should be selected at the same time. Some brands of boilers have complete accessories to meet the needs of a variety of customers. The most important accessory is the thermostat. With it, it can perform zone temperature control, timer switch, etc., energy saving and environmental protection.
6. Look at the after-sales service: the life of the boiler is more than 15 years, apart from the two-year warranty, there is a minimum of 13 years of paid maintenance. In the long 13 years, if there is no good service to protect you, it can really become a hard time. This choice cannot be listened to by the manufacturer, but must be examined, one is the size of the company, the other is the warehouse accessories, the third is the maintenance site, and the fourth is the user feedback.
Summary: Relevant information about the working principle of the gas-fired boiler and the purchase method of the gas-fired boiler is introduced here for everyone.
