How to select the type of solid heat storage electric boiler?
Solid heat storage electric boiler is the preferred equipment for heating in winter in the cold northern region due to its no discharge of three wastes, safety, stability and not affected by the external environment. At present, there are many manufacturers in the market that claim to be able to make solid heat storage electric boilers. What problems should we consider when selecting solid heat storage electric boilers? Which manufacturer's products should be selected, which directly affects the future use cost and protection cost.
Selection Criteria for 1. Solid Heat Storage Electric Boilers
1. Economy: When planning the solid heat storage electric boiler system, it should be confirmed according to the comprehensive consideration of various factors that affect the initial capital contribution and operating cost. Therefore, when planning the plan, the peak and valley electricity price structure of the system and the initial equipment investment will be fully studied. In order to achieve the expected economic benefits, the selection of heat storage and system operation mode will save more operating costs together with the investment at the initial stage of decline, make full use of valley electricity and transfer more peak electricity consumption.
2. High efficiency and energy saving: When planning the heat storage system, the system selection should be confirmed according to the demand of the planning load, the installed capacity of various equipment should be reduced as much as possible, the heat storage power should be improved, the advantages of heat storage equipment should be fully used, and the energy consumption of the system should be reduced as much as possible.
3. Stability: The important basis for evaluating the quality of the heat storage system is the overall efficiency and operational stability of the system. When planning the system, the operation characteristics of the heat storage system should be combined, and various equipment should be selected to make the system cooperate perfectly and meet the requirements of all operations. All kinds of supporting equipment are also required to withstand long-term stable operation testing, reduce the protection of the system, and meet the requirements of life.
2. solid heat storage electric boiler heating power accounting method
Calculation of input electric power of regenerative electric boiler
1. For 24 hours of heating, the power accounting formula is: (heating area * planned heat load target * 24/8 *(0.6-0.7)= input electric power (w)
2. For 12 hours of heating, the power accounting formula is: heating area * planned heat load target * 12/8 *(0.6-0.7)= input electric power (w)
The principle of solid heat storage electric boilers is different from that of ordinary electric boilers, so please do not directly correspond to the type of ordinary electric boilers. Even if the same product is a solid heat storage electric boiler, the power given by each company may be different under the condition of satisfying the same heating demand.
Four objectives should be taken into account in the selection of 3. solid heat storage electric boilers.
Traditional boilers usually only need two main parameters: output power and boiler power, while regenerative electric boilers have four main parameters: input power, output power, heat storage and system power.
Objective 1: Input power of solid heat storage electric boiler
Input power: the power of electric heating, how long the heat can be stored, too small heating power will form electric energy other than the time when valley electricity is required, the operation cost will increase, too large heating power will form the lack of valley electricity, waste capacity electricity, increase unnecessary cable contribution.
Objective 2: Solid heat storage electric boiler heat storage
Heat storage: Heat storage is the main parameter to determine the price of electric heat storage boilers. This parameter determines how much total heat can be output without heating after full heat storage. The more heat storage, the more heat storage, the more heat storage, and the higher the equipment price. Assuming that one equipment with the same heating power is heated 24 hours a day and the other is heated 12 hours a day, since the 24-hour heating machine can generate heat at night while storing heat, the demand for heat storage is small, and the price should be lower than that of the other one. Therefore, it is unreasonable to quote according to the heating power. The lack of heat storage will result in the fact that the heat has been discharged before the valley power is reached, which needs to be supplemented by flat electricity or even peak electricity.
Objective 3: Heating power of solid heat storage electric boiler
Heat release power: The heat release power is equivalent to the output power of the traditional boiler. Since the output power of the heat storage electric boiler will decrease with the decrease of the temperature of the heat storage body, it must be ensured that before the power supply starts every day, otherwise it will form a lack of heating capacity and need to supplement heat.
Goal 4: System Power

System power: Since the work of regenerative electric boilers is divided into 3 processes of "heating-heat storage-heat release", the power of the entire system that completes these 3 processes is the boiler power in the traditional sense. Some manufacturers Confusing the audience and using electric heating power 99% to pass off the system power, but in fact, the electric heating power itself is very high. The loss of this system is mainly in the heat preservation stage and the output stage, it should be guaranteed that the total power is above 95% before it is qualified.
Precautions for Selection of 4. Solid Heat Storage Electric Boiler
Solid heat storage electric boilers are used for heating and have a service life of up to 20 years. When selecting models or confirming manufacturers, keep in mind that price alone cannot be used, and attention should be paid to brands and past performance. Pay special attention to the following points:
1. Heat storage data: Magnesium oxide and iron oxide are mostly used as heat storage data in solid heat storage electric boilers. When confirming manufacturers, we must pay attention to the purity of the data. As the purity is often different by one percentage point, the life span and price are often different by 180,000 miles.
2. Heating data: The price of Ni80Cr20 heating tubes is 5 times higher than that of FeCrAl heating belts, and the life span is several times different. Ni80Cr20 different manufacturers have different durability due to different formulas and packaging modes.
3. Overall structure of equipment: solid heat storage electric boilers must select the structure of separation of electricity and water. In just a few years of the actual heating season, there have been several explosions due to the structure of the heat storage boiler.
