Continuous Flow - Non Condensing

Continuous flow non-condensing gas hot water systems deliver reliable, instant hot water on demand for homes and businesses across New Zealand. These systems, also known as non-condensing or standard tankless heaters, use a single heat exchanger to rapidly heat water as it flows through the unit, so you only use energy when hot water is needed - helping reduce running costs compared to traditional storage tanks.

Key benefits:

  • Endless hot water: Enjoy consistent supply, perfectly suited for growing families or high-usage households.

  • Space-saving: No bulky storage tank required. Compact units are typically wall-mounted outdoors, freeing up valuable space.

  • Temperature control: Set precise outlet temperatures for safety and comfort - great for households with children.

  • Low maintenance: Simple design and fewer components make non-condensing models lower maintenance with a typical lifespan of 15 to 20 years.

  • Cost-effective: Generally lower upfront cost than condensing models, making them a budget-friendly choice for efficient hot water.

While non-condensing units produce hotter exhaust gases and have lower efficiency than condensing systems, they are ideal if you want a straightforward, dependable solution and easy installation without the need for a drain or complex venting.

Continuous Flow - Condensing

Continuous flow condensing gas hot water systems offer one of the most efficient and reliable solutions for unlimited hot water in New Zealand homes. These advanced systems use condensing technology, which means they extract extra heat from exhaust gases using a secondary heat exchanger. This process improves their efficiency by 8 to 15% compared to standard continuous flow units, leading to substantial long-term savings on your energy bills.

Key benefits include:

  • Endless, on-demand hot water: Never run out, no matter how many showers or appliances are in use.

  • Reduce operating costs: By only heating water as needed and utilising waste heat, condensing systems offer excellent cost efficiency over time.

  • Compact and space-saving: Wall-mounted design frees up valuable indoor storage space.

  • Excellent water pressure: Enjoy strong, mains pressure hot water across multiple taps and showers.

  • Safer hot water: Temperature controls help prevent scalding and allow custom settings for added peace of mind, especially in homes with children.

  • Lower carbon footprint: Increased efficiency means less energy is used, reducing both your costs and environmental impact.

Condensing continuous flow systems are ideal for busy households or anywhere space is at a premium, and give you reliable, high-pressure hot water wherever you live in New Zealand. Choose a condensing model for the best in energy efficiency, performance, and long-term value.
