The gas hot water boiler is a clean and environmentally friendly boiler for heating and hot water. It is also widely used in all aspects of industrial production. The products sold on the market can be said to be very diverse. Consumers have brought the opportunity to choose fully, and at the same time, the problem of how to choose the right gas hot water boiler has been put in front of consumers. This requires us to keep our eyes open and understand gas hot water when buying gas boiler The performance of the boiler, Zhengzhou Fangkuai Boiler Co., Ltd. will introduce you the good performance indicators of gas boilers.

When selecting gas-fired hot water boilers, we mainly include selecting services and selecting power. In many cases, when major boiler manufacturers sell their products, they are eloquent about the advantages and promises for after-sales service, but not many can really do as promised. The gas-fired hot water boiler can achieve constant temperature control, regular on and off, and reasonable use of electrical energy. It can be adjusted freely at 40 ℃ -80 ℃.

The gas hot water boiler is also equipped with multiple protection systems, such as double leakage protection, anti-dry-burn protection, over-temperature alarm, etc. After the boiler is started, the temperature rises comfortably and the thermal efficiency can reach more than 98%.

The gas hot water boilers from Fangkuai Boiler manufacturers also have various power options, but everyone must remember to choose the right boiler power. The selected power is large, wasting money and energy. The selected power is small, and the waste of funds and energy is small, but it cannot meet the requirements for use.

The outlet temperature of the gas hot water boiler is above 70 ℃, and the temperature of the radiator is above 75 ℃ in 30 minutes. There is a non-pressure water heating cycle with multiple non-drying and non-pressure water heating cycles. Suitable for winter heating and hot water supply.

With the development of science and technology, boiler equipment and technology are also constantly developing and innovating. The electric steam boiler is a kind of boiler equipment that uses electric energy. After the boiler is running, it is a product that is completely free of pollutants and can be described as an environmental protection pioneer product.

Electric steam boiler equipment has many advantages, and at the same time, the performance of the boiler has also changed. In order to ensure the safe use of the equipment and extend the service life, many boiler technical engineers from Zhengzhou Fangkuai Boiler Co., Ltd. have accumulated years of research and accumulated correct installation and commissioning Some experience will be passed on to everyone for free now.

First of all, when the electric steam boiler leaves the factory, the staff should carefully check whether the physical quantity and the list details are exactly the same, and the integrity of the equipment must be ensured. After arriving in the installation environment, the equipment and components need to be placed on a flat and spacious ground to avoid damage to the brackets and sockets. It is also very important that after the electric steam boiler is fixed, you should carefully check whether there is a gap in the place where the boiler is in contact with the base, ensure that the seams are tight, and that the gaps must be filled with cement. When installing, the most important part is the electrical control cabinet. You need to connect all the wires in the control cabinet to each motor before installing.

Secondly, before the electric steam boiler is officially put into use, a series of commissioning tasks need to be carried out. The two key steps are to raise the fire and supply the gas. The fire can only be carried out after a comprehensive inspection of the boiler without any leaks in the equipment. During the process of the fire, the temperature must be strictly controlled, and the temperature must not be increased too quickly to avoid uneven heating of each component and affect the service life. At the beginning of the air supply, the heating pipe operation must be performed first, that is, the steam valve is slightly opened to allow a small amount of steam to enter, which has the effect of preheating the heating pipe, and at the same time, pay attention to the normal operation of each component.

After the above steps, the electric steam boiler can basically be used normally.

The electric steam boiler is a big star product of Fangkuai Boiler manufacturer. Once it was introduced to the market, it got an extremely warm response. And we have set up more than 200 after-sales service outlets in many places across the country to ensure that it can better serve customers aftersale service provided. So, what are the advantages of electric steam boilers produced by Fangkuai boiler manufacturers?

First, the security is extremely high
       The boiler has various safety protection mechanisms such as leakage protection, water shortage protection, grounding protection, overpressure protection, overcurrent protection, power supply protection, etc. to ensure that the boiler can operate safely and stably.
       1. Leakage protection: When leakage occurs in the boiler, the power is cut off in time through the leakage circuit breaker to ensure personal safety.
       2. Water shortage protection: When the boiler is short of water, cut off the control circuit of the heating tube in time to prevent the dry burning damage of the heating tube. At the same time, the controller issues a water shortage alarm indication.
       3. Grounding protection: When the boiler shell is charged, the leakage current is conducted to the ground through the grounding wire to ensure personal safety. Generally, the protective ground wire should be well-connected to the ground. Angle irons and steel pipes buried in the ground are usually used as grounding bodies. The grounding resistance must not be greater than 4 ohms.
       4. Steam overpressure protection: When the boiler steam pressure exceeds the set upper limit pressure, the safety valve is activated to release the steam and reduce the pressure.
       5. Overcurrent protection: When the boiler is overloaded (the voltage is too high), the leakage circuit breaker is automatically opened.
       6. Power supply protection: Reliable power-off protection is performed after detection of over-voltage, under-voltage, and break fault states by means of advanced electronic circuits.

It is very convenient to operate
       1. After the power is introduced into the electric control box, the boiler will enter (or leave) the fully automatic operation state with one-click operation.
       2. The amount of water in the boiler is reduced, and the control system automatically replenishes water from the water tank to the boiler through the make-up pump.

Third, the boiler design structure is more reasonable
       In order to be able to use electric energy more reasonably and efficiently, Fangkuai Boiler manufacturers have divided the heating power into several sections, and the controller automatically turns on (cuts off) the cycle. After the user determines the heating power according to the actual needs, he only needs to close the corresponding leakage circuit breaker ( Or press the corresponding switch). The segmented cycle switching of the heating pipe reduces the impact of the boiler on the power grid during operation.

Fourth, the boiler runs more reliably
       1. The body of the boiler is backed by argon arc welding, and the cover surface is welded by hand, which is strictly inspected by X-ray inspection.
       2. The electric steam boiler uses steel and is selected in strict accordance with national manufacturing standards. 3. The accessories used in electric steam boilers are selected from high-quality products at home and abroad and tested by the test furnace to ensure the long-term normal operation of the boiler.

Gas hot water boilers, as the products of Fangkuai Boiler Co., Ltd. with sales No. 1 in heating and heating, are well received by users. Today we will tell you why it is more energy efficient and environmentally friendly to use gas hot water boilers for heating?

Generally, gas-fired hot water boilers are used for heating. Except for less production processes, steam must be used because it is more energy efficient and environmentally friendly than using steam boilers. First of all, in terms of fuel consumption, hot water boiler heating saves 20 to 40% of fuel compared to steam boiler heating, which is a considerable amount.

The Fangkuai boiler manufacturer summarized these two reasons: one is that it has no heat loss caused by condensate and secondary evaporation; the other is that the hot water heating pipe uses special thermal insulation materials, and the pipe is also as far as possible under the condition of meeting the needs The thickness is small and the heat loss is small. The heat loss caused by steam leakage in the steam heating pipeline is relatively large, while the gas hot water boiler only needs a small amount of regular blowdown.

Another advantage of using gas-fired hot water boilers for heating is that the quality and temperature of hot water can be flexibly adjusted. When the outdoor temperature is low, the hot water temperature needs to be increased to meet people's needs. When it is higher, the temperature of hot water can be lowered, which not only can meet people's needs, but also achieves the effect of energy saving and environmental protection. And its system maintenance costs are also lower.

Gas-fired hot water boilers can heat districts that are tens of kilometers away. Fangkuai boiler manufacturers have a good performance in this regard.

Therefore, in general, the economic benefits of using gas-fired hot water boilers are significant, and the energy saving and environmental protection effects are better.
