More than meets the code: Enamels that deliver confidence
Across industries, 2025 has been defined by uncertainty. Economic pressures, trade tensions and shifting regulatory landscapes are reshaping expectations worldwide. As market confidence dips, consumers are becoming more selective — scrutinizing their buying choices and gravitating toward brands that demonstrate reliability, transparency and long-term value.
In today’s cautious market environment, earning customer trust is more challenging – and critical – than ever. Consumers want assurance that the products they rely on every day are safe, dependable and built to last, especially when it comes to essential home appliances. Hot water tanks, for example, are a fundamental part of the home, playing a vital role in delivering safe, reliable water for everyday use.
For hot water tank manufacturers, meeting baseline compliance requirements is no longer enough. They must show a clear commitment to safety, durability and responsibility. Consumers, regulators and workers alike expect manufacturers to use safer, high-performing and long-lasting materials that protect household appliances throughout their extended service life.
What is driving change in hot water tanks?
Hot water tanks are fundamental to modern living, yet the requirements around their production have evolved dramatically. Worldwide, manufacturers are navigating new challenges such as:
- Tighter drinking-water quality regulations:
Mandates like the European Directive 2020/2184 set stringent limits on the migration of substances from tank materials into potable water. This increases demand for advanced enamel formulations that provide certifiable corrosion protection in line with standards such as DIN4753-3 (2025 02).
- Enhanced occupational health and safety standards:
Companies are prioritizing the well-being of their workforce through responsible manufacturing practices. This transition involves adopting safer enamel coatings, such as nickel-free and low-quartz options, which reduce skin and respiratory hazards, with some of our solutions qualifying for label-free classification under EU safety standards.
- Higher performance demands from modern water chemistries:
Enameled tank interiors must endure increasingly harsh conditions. Softened water can accelerate corrosion and increase thermal stress — factors that ultimately shorten the lifespan of hot water tanks.
Modern water tanks must deliver higher reliability than ever before while protecting both people and resources for years to come. Vibrantz has been advancing porcelain enamel technology for over a century, helping manufacturers meet heightened demands with confidence.
