🥵 What Are Boiling vs Instant Hot Water Taps?

“Boiling water” is 100 °C, but many “boiling” taps output around 85–95 °C. That’s enough for everyday kitchen tasks - but not quite full boil. If you want the real 100 °C, look for QETTLE certification or check the specs carefully.

💧 Flow, Noise & Steam - What to Expect

• Flow: Steam in the line softens the flow - normal with near-boiling taps.
• Noise: A soft hiss or bubbling is expected.
• Steam: Full boil taps may produce visible steam; 85–95 °C taps usually don’t.

🤔 What to Think About Before Buying

• Check the exact temperature - 85 °C may not fully dissolve granules.
• Consider noise/steam - especially if your kitchen is small or low ceiling.
• Think about installation - pressurised tanks require space and professional setup.
• Look for certifications like QETTLE to ensure full 100 °C output.

❓ FAQs

Why don’t some taps reach 100 °C?

Many models are intentionally set around 85–95 °C to balance energy, safety, and pump pressure.

Is a bit of noise or steam dangerous?

No - it's normal for superheated water in a compact tank and controlled outlet.

Do these use much electricity?

No - modern units are well insulated and only reheat when needed, not continuously.

Can you retrofit one easily?

Yes, but you need space for the tank, an electrical point, and a dedicated hot-water line. EcoFilter handles all this cleanly and safely.
