🥵 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.
