Canon IGWH-20DD 10-Litre Instant Gas Water Geyser

Need reliable hot water without waiting for a large storage tank to heat up? The Canon IGWH-20DD 10-Litre Instant Gas Water Geyser delivers hot water on demand for everyday home use. This compact instant gas water heater heats water as it flows through the unit, making it a practical choice for kitchens, bathrooms, or any space where continuous hot water is required. With a rated output of 10 litres per minute and a solid copper heat exchanger, it balances performance and convenience for medium household needs.

Key Features of the Canon IGWH-20DD 10-Litre Instant Gas Water Geyser

The dual power ignition system is one of the most useful features. You can start the unit using either 1.5V D-size batteries or the included AC power adapter. This flexibility helps in different installation setups and reduces dependency on a single power source.

A 2.2 KG copper heat exchanger sits at the core of the heating process. Copper transfers heat efficiently, allowing the unit to deliver up to 10 litres of hot water per minute once gas and water flow are properly connected.

Because it is an instant (tankless) design, the Canon IGWH-20DD does not store large volumes of hot water. Water is heated only when you open the tap, which can help reduce standby heat loss compared with traditional storage geysers.

The package includes practical accessories such as an AC power adapter for ignition and flexible connection pipes, making installation more straightforward. A 1-year warranty provides basic coverage under the manufacturer’s terms.
