If you still heat your home with natural gas, a new European emissions trading system – ETS2 – is about to make that choice more expensive. From 2027, energy suppliers will have to pay for the CO₂ emissions from the fossil fuels they deliver. And those costs will almost certainly be passed on to you.

On 19 May 2026—less than a month after industry organisations called for a recurring EU Innovation Fund Heat Auction—the European Commission confirmed that a second auction will take place later this year. The announcement sends a powerful signal that industrial heat electrification is now a core pillar of Europe’s competitiveness, industrial resilience and energy security. For manufacturers of heat pump water cylinders and thermal storage systems, this is the moment to move from pilot to scale.

It is about proving what we have always believed—that stainless steel is the gold standard for safe, clean water storage.

But what does this process actually look like for a stainless steel tank? What tests do we have to pass? And why should you, as a customer, care?

Let us take you inside the DWD certification process for stainless steel water tanks.

Does Legionella in hot water systems pose a health risk? This microorganism can multiply rapidly at temperatures typical of many hot water systems, making proper temperature settings and regular overheating essential. How does Legionella operate, and how can the risk of infection be effectively reduced?

• Temperature Favorable for Bacterial Growth – Legionella grows most vigorously in water temperatures between 20-45°C. Reproduction is restricted above 50°C, and temperatures above 60°C effectively kill the bacteria.

• Overheating Protection Mechanism – Regularly raising the domestic hot water temperature above 60°C performs what is known as thermal disinfection of the system. In many modern systems, this function runs automatically every few days or weeks.

• Infection via Water Aerosols – The bacteria are not transmitted by drinking water but through the inhalation of tiny droplets, such as those generated during showering. Elderly individuals and those with weakened immune systems are most susceptible to severe illness.
