That question eventually led several importers from Latin America and Europe to book factory visits in China. Many of them had tested samples before. Some even had price lists from multiple suppliers. But before making their final decision, they wanted to see the manufacturing process with their own eyes.

One of the factories they chose to visit was Greaidea — a long-term OEM gas water heater manufacturer known for supplying brands across Europe, Latin America and the Middle East. What happened during that visit changed more than just pricing discussions — it shaped long-term partnerships.

Several buyers admitted they arrived with doubts. They expected a standard facility with assembly lines and quality claims printed on posters. What they found instead was a production system that they described as "surprisingly transparent."

The tour began with the core production floor — where tructured assembly lines were running in full operation. From there, buyers were guided through the testing area, where each unit undergoes individual inspection before packaging. They also visited the testing lab, where engineers demonstrated how a gas water heater is tested for long-term usage — simulating real-life operation under different conditions. Several buyers later said this sequence of transparency—from assembly to testing to lifespan simulation—was what convinced them that quality was not just claimed, but proven.

Instead of explaining with brochures, the engineers simply opened live dashboards showing daily output and inspection data. That moment reduced doubts more than any sales pitch could.

What stood out to the buyers wasn't only the well-managed production line, but the practical conversation that followed. In a meeting room next to the assembly area, Greaidea's team focused on how different regions demand different product configurations — based on market size, installation habits, family usage patterns, and local certification standards.

Some buyers asked about suitable capacity levels for apartment projects in Europe; others discussed consumer preferences for digital display models in Mexico City. A distributor from Brazil was particularly interested in how documentation and compliance testing could align with upcoming regulations. These exchanges gave buyers confidence that product design could be tailored — not just produced.

One of the importers later said,

"We were not just shown products. We were shown how our market problems could be solved."

Samples can look perfect. But buyers often worry: "Will mass production be consistent?"

During the tour, the buyers were impressed by the way safety and reliability were tested in real field conditions. Instead of just showing finished products, the factory demonstrated how each gas water heater goes through multiple verification steps — including overpressure protection checks, anti-dry-burning mechanisms, drop testing for sea shipping, and aging inspections for electronic components. It showed that every model is not only built to function but built to withstand real-life use and unpredictable conditions in the market.

Some buyers recorded videos to send to their local teams. According to feedback, those videos helped convince distributors back home to upgrade their own product lines.

This transparent testing process became a deciding factor — especially for brands aiming to position themselves at the mid-to-high range market in 2026.

"We don't need the cheapest supplier. We need a manufacturer that helps us sell in our market. That's what we found here."

A buyer from Chile said that visiting the OEM facility helped his company improve its local product positioning immediately — simply because the manufacturer provided capacity suggestions, and packaging adjustments for different retail channels.

Across all remarks, three strengths were mentioned repeatedly:

OEM & ODM support for market-specific models

Real warranty — up to 5 years, with spare parts guaranteed

Strong manufacturing capabilities & Strict product quality system

This combination made many buyers conclude that switching suppliers could bring long-term value instead of short-term risks.

The gas water heater market is shifting. Importers no longer choose suppliers based only on price. Instead, they are looking for measurable quality, documented testing, real OEM capability, and after-sales support that protects their brand name.

Factory visits will likely increase in 2025 — especially among buyers who want strategic partnerships rather than transactional sourcing. Based on the feedback, one message stood out clearly:

"A strong OEM manufacturer is not just a factory — it's part of your product strategy."
