Rinnai HydraHeat® Integrated Hot Water Heat Pump

Slash your energy bills and future-proof your home with the Rinnai HydraHeat® Integrated Hot Water Heat Pump, now available at Pratts. Developed by Rinnai, the trusted name in New Zealand home comfort, this highly innovative system combines advanced heat pump technology with high-performance water heating. Engineered to lower your water heating bills by up to 75%, it represents a smarter, cleaner, and far more sustainable hot water cylinder upgrade for New Zealand homes.

Designed primarily for outdoor installation, the Rinnai HydraHeat® integrates beautifully into modern home designs. It can also be installed internally if the location is a non-occupied space in accordance with AS/NZS 5149 standards. For trade professionals looking for trade quality reliability and homeowners wanting an efficient heating solution, the HydraHeat® delivers exceptional performance even in the harshest Kiwi climates.

Why Choose the Rinnai HydraHeat® Integrated Heat Pump?

• Up to 75% Energy Savings: Enjoy highly efficient water heating that significantly reduces household power consumption and lowers monthly utility costs when compared to a standard 250L electric hot water cylinder.
• Designed and Built in New Zealand: The HydraHeat® head unit is specifically engineered to withstand New Zealand's unique climatic conditions, operating reliably in temperatures ranging from -10°C up to +42°C, including coastal areas. It operates in full heat pump mode down to -10°C without requiring expensive electric element boosting.
• Eco-Friendly & Sustainable: Powered by a minimal nominal charge of just 150g of high-efficiency R290 refrigerant. This natural refrigerant features a virtually zero Global Warming Potential (GWP) and delivers an impressive Coefficient of Performance (COP) of 4.7.
• Modular 'Heat Pump Ready' Design: Future-proof your property. Install the standalone HydraHeat® electric cylinder now and easily upgrade to full Hot Water Heat Pump technology later simply by adding the HydraHeat® head unit.
• Whisper-Quiet Operation: Operating at a low sound level of just 45dB(A), this system is perfect for high-density residential areas, close-boundary installations, and quiet suburban neighborhoods.
• NZ MEPS Compliant: Fully compliant with New Zealand Minimum Energy Performance Standards (MEPS), ensuring minimal standby heat loss and maximum running efficiency. Note that not all hot water heat pumps on the NZ market meet these strict standards.
• Dependable Backup: An integrated backup electric element guarantees a continuous, uninterrupted supply of mains-pressure hot water even during periods of exceptionally high demand.
• User-Friendly Interface: Features an intuitive OLED control screen with six versatile operating modes to suit your lifestyle: Standard, Boost, Eco 55, Eco 50, High Usage, and Element Only.
• Industry-Leading Warranties: Rest easy with a 5-year warranty on the heat pump unit and a 7-year warranty on the cylinder, backed by Rinnai New Zealand's renowned service network.
