Hot Water

The great part about an instant electric hot water system is in the name. With these systems, you get hot water exactly when you want it, with virtually no time taken in the heat-up process. For storage electric hot water systems, the heat-up time depends on the size of the tank. On average, it takes 1-2 hours for a fully drained system to heat your water.

Instant electric hot water systems are an energy-efficient way to heat your water. This makes them more cost-effective. Instant hot water systems only draw power when they are in use, while storage systems can heat up to 300L of water 24/7.

Compared to a storage water heater, an instant electric water heater could deliver savings of up to 25% off household energy bills annually (based on electricity cost to Sydney metropolitan postcode).

There are a few key differences to keep in mind when comparing instant and storage hot water systems:

• With an instant hot water system, there’s no need to wait for your hot water. Water is heated on demand and the system is installed close to the outlet. With a storage system, you’ll need to wait longer for your hot water.
• Instant hot water systems can offer an endless supply of hot water. Storage systems can run out of hot water when it is needed.
• Instant hot water systems are more energy efficient than storage hot water systems. Continuous flow systems only consume energy when they are in use, while storage units consume energy constantly. This means instant hot water systems can save you money and are a more eco-friendly option.
• Instant hot water systems are not subject to heat loss as hot water is not stored in the system. The water is heated and dispersed immediately with no need to reheat it.

Instant hot water systems have numerous benefits compared to storage hot water systems, but storage systems can be suitable for some customers.

Instant electric hot water systems heat water when it is required. When the water is needed, cold water enters the water heater through the inlet pipe. A sensor detects the water movement, activating the electric heating element.

The water passes through a heat exchanger, where the heating element raises its temperature. The system continues to supply hot water as it is needed. When the appliance or tap is turned off, the flow ceases and the flow sensor deactivates.
