概要： Here, Dayu wall‑mounted boilers would like to share some important information. At present, in the domestic market, no other manufacturers have been found to produce counterfeit products in the wall‑mounted boiler industry. In other words, as long as you purchase your boiler through official channels, you can be confident that you will not receive a fake or substandard product. Additionally, when buying a wall‑mounted boiler, be sure to verify that the manufacturer holds the necessary national production license, test reports, and other relevant certifications.

At present, in the domestic market, no other manufacturers have been found to produce counterfeit products in the wall‑mounted boiler industry. In other words, as long as you purchase your boiler through official channels, you can be confident that you will not receive a fake or substandard product. Additionally, when buying a wall‑mounted boiler, be sure to verify that the manufacturer holds the necessary national production license, test reports, and other required certifications.

　　Here, Dayu wall‑mounted boilers would like to share some important information. At present, within China’s wall‑mounted boiler industry, no other manufacturers have been found to produce counterfeit products. In other words, as long as you purchase your boiler through official channels, you can be confident that you are not buying a fake or substandard item. Additionally, when buying a wall‑mounted boiler, be sure to check whether the manufacturer holds the necessary national production license, test reports, and other relevant certifications. More and more people are now taking an interest in and using wall‑mounted boilers, but this has also led to an increasing number of issues. For example, some customers, after receiving advice, install a boiler of the same brand and model as their neighbor’s or friend’s, yet they feel their home does not heat as well. This can lead them to wonder if their product is defective or inferior, leaving them feeling uneasy.

　　Why might you feel that your home’s heating performance isn’t as good as your neighbors’ after installing a wall‑mounted boiler? First, keep in mind that for boilers of the same model from any brand, the thermal efficiency is necessarily identical. So, if you notice poor heating performance, check whether your home exhibits any of the following conditions:

　　1. Ambient temperature: For the same furnace, the heating area and gas consumption during winter will undoubtedly differ between southern and northern regions due to varying temperatures.

　　2. Building thermal insulation: Whether the building envelope provides adequate insulation and whether doors and windows are thick and tightly sealed significantly affect gas consumption. The difference in gas usage between energy-efficient and non-energy-efficient homes is substantial. Enhancing the thermal performance of the building envelope is a fundamental solution for energy conservation, but this is not something that can be addressed by installing wall-mounted boilers; it is a matter of broader national policy direction.

　　3. Set temperature: Depending on individual preference, the temperature can range from the teens to the twenties Celsius, and the corresponding gas consumption will naturally vary. For every 1°C increase, gas consumption rises by 5% to 9%.

　　4. Wall-hung boiler thermal efficiency: Conventional wall-hung boilers typically range from 88% to 95%, while condensing models achieve higher efficiencies.

　　5. Housing characteristics: The orientation of the house and the wind conditions in the surrounding environment affect heat dissipation. Detached houses with cold walls tend to lose heat faster than compact houses with shared walls, and lower and upper floors dissipate heat more quickly than middle floors. Additionally, having no neighboring residences on all sides also influences heat loss. All these factors impact gas consumption.

　　6. Condition of the property: New buildings tend to be quite damp, and during the first year after moving in, gas consumption can be very high—especially with underfloor heating, which initially requires a significant amount of gas to dry out the floors and walls.

　　7. System performance: Whether the piping circulation is smooth, the temperature difference between supply and return in the heating system, and the quality and compatibility of pipes, underfloor heating, radiators, etc., are all key factors.

　　8. Temperature control measures: Whether a thermostat is installed, and whether temperature can be adjusted by time period or heating can be regulated intermittently, etc.

　　9. Operating conditions: Verify that the water and electricity supply in the operating environment are normal, and that the gas quality is satisfactory.

　　10. Heating area, heating duration, and gas prices are rigid determinants of operating costs.

　　As such, whether a wall‑mounted boiler heating system is energy‑efficient depends on more than just the boiler’s own thermal efficiency. As the saying goes, “Three parts product, seven parts installation.” Energy savings must apply to the entire system, not merely to a single piece of equipment—such as the wall‑mounted boiler. Evaluating the efficiency of any one component in isolation is of little use; only when the overall system efficiency is high does it truly matter.

Mom and Dad, you’ve worked so hard!
