AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier for gas and household appliances, with 3D software design, OEM, ODM, and broad customization capabilities. It reports multiple product, quality, environmental, safety, and service certifications, supported by testing and production equipment. Production-related evidence includes an assembly line, automated machinery, and specialized boiler testers, while the stated off-season lead time is within 15 workdays. Quality controls include assurance and raw-material traceability, but several procedures lack documented records. Financial credibility cannot be confirmed because the provided financial figures are zero. Innovation evidence is mixed: the supplier has patents and one R&D engineer but reported no new products in the past year and no available SDK. Customer evidence includes OEM service for well-known brands and an 80%–100% repeat-buyer preference, but no Fortune 500 cooperation.
Supplier typeThe supplier explicitly identifies as a professional technical supplier and operates in gas appliances, household appliances, and related installation, spare-parts, and non-electric appliance businesses. It also provides OEM and ODM services, indicating a manufacturer with technical and production functions.
CertificationsThe supplier reports National Energy Conservation, National Environmental Protection, CCC, five-star product, after-sales service, gas appliance installation and repair, and multiple patent-related credentials. It also lists ISO9001:2015, ISO45001:2018, and ISO14001 management certifications, providing explicit evidence of broad compliance and management-system coverage.
After-Sales capabilityEvidence includes Star-Rated After-Sales Service Certification, gas appliance installation and repair qualification, and the ability to participate in offline exhibitions. However, complaint-handling procedures have no written records, and the service corrective-action mechanism and supplier-service procedures also lack records, limiting evidence of consistently documented execution.
Production capacityThe supplier reports an assembly line, automatic laminating and palletizing machines, laser marking equipment, online and safety testers, and dedicated household and commercial heating hot-water boiler testers. Its stated off-season lead time is within 15 workdays, while its business scope includes production of gas and household appliances, directly supporting manufacturing capability.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its 3D design service, ODM capability, and OEM service further support the ability to develop or adapt products for customer requirements.
Client casesThe supplier states that it provides OEM services for well-known brands and reports an 80%–100% repeat-buyer preference. It has no reported cooperation with Fortune 500 companies, and the only specifically named external activity is participation in the Uzbekistan Industrial Products Exhibition 2025; therefore, customer references are positive but limited in detail.
Product Q&A
Q:How to choose the power of the wall-mounted boiler to match my home layout?
A:
For ordinary residential buildings of 80-150 square meters, choose 24KW, which can meet the heating and hot water needs of one kitchen and two bathrooms; Choose 28KW or above models for 150m2 or larger floor-to-ceiling units or villas; For homes in the south without insulation or those with multiple bathrooms, it is recommended to increase the power by 20% to 30% to avoid insufficient hot water or heating.
Q:Does the online purchase of a wall-mounted boiler include installation services? How much is the charge for auxiliary materials?
A:
Most online shopping models of brands include free basic installation, but do not include special fees such as high-altitude work and wall drilling. Auxiliary materials such as pipes, corrugated pipes, and filters need to be purchased separately. The total cost of auxiliary materials and special installation fees is usually around 1,000 yuan, and you can consult customer service to confirm the details of the package.
Q:Can a dual-purpose wall-mounted boiler provide both heating and hot water at the same time?
A:
It can't run at the same time, the hot water function will start first. The machine will automatically switch between heating and hot water mode according to the opening of the hot water faucet, and the heating will be temporarily suspended when taking a bath, and the heating will resume after the hot water is turned off.
Q:Is there a big difference between first-class energy efficiency and ordinary wall-mounted boilers? Is it worth spending more money to buy it?
A:
The main difference lies in energy efficiency. Most of the first-class energy efficiency is condensing wall-mounted boilers, and the thermal efficiency can reach more than 107%. It can save 15% to 20% of the gas fee compared with ordinary non-condensing boilers. It is very cost-effective to use it for a long time, especially for large houses or families who use hot water for a long time, and the saved gas fee can quickly cover the difference.
Q:The old house doesn't have pre-installed heating pipes, can I install this wall-mounted boiler?
A:
Sure. For old houses or houses that have already been renovated, you can choose the open-air radiator system, which does not need to damage the walls and decoration during construction, has a short construction period, and has a good appearance after installation. After placing the order, you can book a master to measure and design the installation plan at home.
