3. Six key steps to choose a wall-hung boiler
1. Determine housing needs
Choose the power according to the house area: 18-20kW is recommended for less than 80㎡; 24kW is recommended for 80-120㎡; 28kW or more is required for 120-200㎡.
2. Select heat source type
Ordinary gas wall-hung boilers have low initial investment but average efficiency; condensing wall-hung boilers are 30%-50% more expensive but save 15%-20% of gas bills every year.
3. Brand comparison
| Brand type | Represent the brand | Advantages | average price range |
|---|---|---|---|
| Imported high-end | Weineng, Bosch | Technology is mature | 8000-15000 yuan |
| Domestic first-line | Wanhe, Haier | High cost performance | 4000-8000 yuan |
4. Energy efficiency label verification
Be sure to check the "China Energy Efficiency Label" affixed to the fuselage. The thermal efficiency of first-class energy efficiency products must be ≥96% (condensing type) or ≥94% (ordinary type).
5. Installation service inspection
Focus on: whether free on-site measurements are provided, whether there are professional installation qualifications, and whether labor costs are included in the warranty period (it is recommended to choose a warranty of more than 5 years).
6. Later maintenance costs
The average annual maintenance cost is about 200-500 yuan. It is recommended to choose a model with an "automatic cleaning" function to reduce the frequency of maintenance.
4. Real feedback from consumers in 2023
| satisfaction factor | Positive rating | Main reasons for bad reviews |
|---|---|---|
| Energy saving effect | 92% | The actual gas bill is higher than advertised |
| Silent performance | 85% | low frequency noise at night |
| After-sales response | 78% | Service delays in remote areas |
5. Special suggestions from experts
1. Newly renovated homes give priority to "dual-purpose" wall-mounted boilers (heating + domestic hot water)
2. When renovating an old house, please check whether the existing gas meter supports G2.5 flow rate (minimum requirement)
3. Measure the minimum water inlet temperature in winter before purchasing. In northern areas, it is recommended to choose a cold-resistant type.
Through the above structured data analysis, combined with your own budget and usage needs, you can select the most suitable wall-mounted boiler product. It is recommended to complete the purchase during the promotion season from October to November, and you can usually enjoy free installation and other discounts.
