Integrated Hot Water System

Yes, there is a model for every NZ household size. Integrated units are "all-in-one" systems where the heat pump sits directly on top of the cylinder, making them ideal for homes with limited space.

• 1 - 3 People: The Carrier Blue 190L is the most efficient choice for smaller footprints.
• 4 - 6+ People: The Rinnai HydraHeat (275L or 340L) is recommended for larger families needing high storage capacity.
• Small Sections: Because they don't require a separate outdoor evaporator unit, they are perfect for tight subdivisions.

Save up to 60% to 75% on your water heating costs. Since water heating typically accounts for a third of your total energy bill, this switch has a massive impact.

• Average Savings: A typical family can save $800 - $1,200 per year.
• Efficiency: These systems turn 1kW of energy into roughly 4kW of heat (COP 4.0+), whereas standard electric cylinders are a 1:1 ratio.
• Gas Comparison: You’ll eliminate fixed daily gas connection fees and the rising costs of LPG or Natural Gas.

Yes, provided you choose a unit with a high "recovery rate." Modern integrated systems are designed to reheat water rapidly to ensure you don't run out during peak times.

• Back-to-Back Showers: Even after heavy morning use, the system begins replenishing hot water immediately.
• Boost Mode: Most units include an emergency element for "one-touch" rapid heating if you have extra guests staying.

Most installations fall between $7,500 and $11,000, including GST. This is a "fully installed" price, though the final cost depends on your specific home layout.

• Rinnai HydraHeat (275L - 340L): $9,500 - $11,000.
