AO Smith Fast-On Instant Geyser, 3000 W

Overview

AO Smith Fast-On is a compact, point-of-use instant water heater built for quick hot water at a single tap — ideal for a wash basin or kitchen sink where a full storage geyser isn't needed. Features a Blue Diamond glass-lined tank for corrosion resistance and is rated for high-rise plumbing pressure.

Key Specifications

• Brand: AO Smith
• Series: Fast-On
• Power: 3000 W
• Tank: Blue Diamond glass-lined
• Pressure rating: 8 bar (suitable for high-rise buildings)

Available Volume Capacities

• 3 Litres — fastest heat-up, best for a single wash basin or hand-wash point with light, quick-draw usage
• 5 Litres — slightly more standing hot water, a better fit for a kitchen sink or a basin used more frequently through the day

How to Use

1. Mount close to the point of use — Fast-On is designed for single-tap, point-of-use installation, not whole-home supply.
2. Ensure the inlet water pressure and your building's plumbing are compatible with the 8 bar rating, especially in high-rise installations.
3. Have a licensed electrician/plumber handle electrical earthing and pressure-relief valve installation.
4. Allow the unit to heat fully before first use; service the tank periodically per the manufacturer's schedule.

Frequently Asked Questions

Is this a replacement for a full-size storage geyser?
No — Fast-On is a point-of-use unit for one tap. For bathroom/shower use with sustained hot water, a larger-capacity storage geyser is a better fit.

Is it suitable for high-rise apartments?
Yes, it's rated for 8 bar pressure, which covers typical high-rise plumbing pressure.
