When choosing a suitable hot water boiler, it is necessary to make a comprehensive judgment based on multiple factors such as the usage scenario, heat load demand, fuel type, operating cost, and safety regulations. The editor has compiled the selection steps and core requirements for your reference.
1. Determine the core requirements
Thermal power is the primary basis for selecting a hot water boiler, referring to the amount of heat that needs to be provided within a unit of time, with units of kW (kilowatt) or MW (megawatt).
Civilian scenarios (residential buildings, office buildings, hotels) : Based on empirical estimates, heating in the north requires approximately 80-120 W/㎡, while in the south, it requires about 60-80 W/㎡. Multiply by the total building area and reserve a margin of 10% to 20% at the same time (to deal with extreme weather and heat loss from pipelines).
Industrial scenarios (factories, workshops, large bath centers) : In addition to heating, the heat demand for production processes and hot water supply should also be taken into account. Precise calculations should be made in combination with equipment parameters, water consumption, and water temperature differences. It is recommended that professional engineers do the calculation.
2. Select the fuel type
Boilers of different fuels vary significantly in terms of operating costs, environmental protection requirements, and installation conditions. It is advisable to select the appropriate fuel type based on local actual conditions.
3. The required installation space
Small boilers are suitable for places with limited space. Large coal-fired and biomass boilers need to reserve boiler rooms and fuel storage areas.
4. Maintenance costs
Gas and electric boilers are easy to maintain, requiring only regular inspections of the burners and pipelines. Coal-fired and biomass boilers require regular ash cleaning and grate inspection, resulting in relatively high maintenance costs.
5. The qualifications and certificates of the boilers they possess
Choose a regular brand with a special equipment manufacturing license and relevant certificates (CE,ISO,ASME) to ensure that the products comply with national standards. At the same time, pay attention to the after-sales service of the manufacturer (such as installation guidance and maintenance response speed).
