How to choose the power of wall-hung boiler
As winter approaches, wall-hung boilers have become an important heating device for many homes. However, how to choose the right wall-hung boiler power confuses many people. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the selection method of wall-mounted boiler power, and provide structured data for reference.
1. The importance of wall-hung boiler power selection
The choice of wall-hung boiler power is directly related to heating effect and energy consumption. If the power is too small, it may lead to insufficient indoor temperature; if the power is too large, it will cause a waste of energy. Therefore, reasonable selection of wall-hung boiler power is the key to ensuring comfort and economy.
2. Factors affecting the power selection of wall-hung boilers
The following are the main factors that influence the choice of wall-hung boiler power:
| factors | Description |
|---|---|
| House area | The larger the area, the higher the power required |
| House insulation performance | Poor thermal insulation performance, higher power required |
| Regional climate | Colder areas require higher power |
| Domestic hot water demand | Large demand for hot water requires higher power |
3. Wall-hung boiler power recommendation table
Depending on the size of the house and the regional climate, the following is the recommended range of wall-hung boiler power:
| House area (㎡) | Mild climate (kW) | cold climate (kW) |
|---|---|---|
| 60-100 | 18-24 | 24-28 |
| 100-150 | 24-28 | 28-32 |
| 150-200 | 28-32 | 32-36 |
| 200-250 | 32-36 | 36-42 |
4. How to accurately calculate the required power
In addition to referring to the recommended table, you can also accurately calculate the required power through the following formula:
Required power (kW) = House area (㎡) × Heat load per unit area (W/㎡) ÷ 1000
Among them, the values of heat load per unit area are as follows:
| House type | Heat load per unit area (W/㎡) |
|---|---|
| New energy-saving buildings | 50-70 |
| ordinary building | 80-100 |
| old building | 100-120 |
5. Common misunderstandings in power selection of wall-hung boilers
1.The more power, the better: Excessive power will lead to energy waste and increase operating costs.
2.Ignore domestic hot water needs: If a large amount of domestic hot water is needed, additional power needs to be added.
3.Ignore regional climate differences: In cold areas, the power needs to be appropriately increased.
4.The insulation performance of the house is not considered: Houses with poor insulation require higher power.
6. Summary
Choosing the appropriate wall-mounted boiler power requires comprehensive consideration of factors such as house area, insulation performance, regional climate and domestic hot water demand. By referring to the recommendation table or accurate calculation, you can find the most suitable power, which can not only ensure the heating effect, but also save energy.
