A Professional Reminder to Our Valued Customers: How to Avoid Counterfeit Products and Choose a Trusted Manufacturer
Dear Customers and Partners,
Recently, we have observed an increasing number of counterfeit gas water heaters circulating in the market. These products are often promoted as “factory-direct," “high-end," or “low-price wholesale," but many buyers end up receiving units with extremely poor internal components, unstable performance, or even no safety protection at all.
To help you avoid unnecessary risks and protect your business interests, Vanka has prepared the following essential guidance.
01 | Why You Should Be Alert to Counterfeit Gas Water Heaters
Some resellers use fake factory photos, forged certifications, and unrealistically low prices to attract buyers. However, the products they deliver often have serious issues:
Inferior or recycled components
Unstable ignition and temperature fluctuation
No gas-tightness inspection or safety testing
No technical support or warranty
Short lifespan and difficult returns
Such products can cause operational problems, customer complaints, and damage to your brand reputation.
02 | How to Quickly Identify Whether a Supplier Is Reliable
Here are several practical ways to help you avoid scams:
1. Request real factory proof
Legitimate manufacturers can provide real workshop videos, equipment photos, and allow video factory inspections.Vanka welcomes you to visit our factory onsite or via video call.
2. Check the quality of key internal components
Reliable water heaters should be equipped with compliant burners, solenoid valves, thermocouples, thermostats, and copper or stainless-steel heat exchangers.All Vanka components come from certified and stable suppliers.
3. Ask for pre-shipment testing videos
Including ignition tests, temperature rise tests, wind pressure tests, and gas-tightness tests.Every Vanka unit undergoes 100% full testing before delivery.
4. Be cautious of prices far below the market
Extremely low prices often indicate low-quality, refurbished, or assembly-line scrap products.
