Frequently Asked Questions about Shower Heaters

How does a shower heater work?

An instant shower heater heats water as it flows through the unit using an internal coil. You get hot water instantly—no storage tank involved.

How to use a shower heater?

Simply switch on the unit, adjust the temperature or flow controls, and enjoy. Our shower heaters require minimal setup once installed.

Why does my tankless water heater go cold mid‑shower?

Cold-outs usually happen when the water flow dips below the minimum (around 2 L/min). Models with built-in pumps maintain consistent pressure to avoid this.

What if the water heater leaks when the shower is on?

Check those fittings first. If the leak’s from the unit, shut off water and power and contact NNIO support as internal seals may need attention.

How to install a shower heater?

Mount the unit securely on wall brackets, connect water and power, and test the safety systems. We can provide contact information for vetted installers upon order confirmation.

Instant vs Storage Heaters: Which one do I choose?

An instant shower heater delivers hot water on demand without a bulky tank—heating water only when needed. This makes it compact, energy-efficient, and quicker to deliver hot showers—meaning less wasted heat in Singapore’s humid climate. While storage heaters can supply multiple outlets simultaneously, they’re larger, less efficient due to standby heat loss, and require more space and maintenance.

Built for Comfort, Made Simple

NNIO’s instant shower heater Singapore lineup is designed for simplicity, safety, and everyday reliability. Whether you need a quiet pump, minimal form, or quick heating—this is hot water with no extra layers.
