Retrofit Your Water Heating System

Yes, with some caveats, your cylinder will need to be mains pressure and under 8 years old. Retrofitting is the ideal way to upgrade your existing infrastructure while saving energy and reducing monthly costs.

• Re-utilise Your Asset: This process allows you to keep your functional cylinder and simply replace the inefficient heating element with a heat pump.
• Compatibility Check: Most modern mains pressure tanks are suitable, making this a cost-effective alternative to a full system replacement.
• Sustainable Choice: By reusing your current cylinder, you reduce waste while embracing 21st-century energy efficiency.

Retrofitting is the best choice if your cylinder is relatively new (less than 5–8 years old) and in excellent condition. It allows you to access heat pump efficiency without the cost of a new tank.

• Sustainability: Reusing your existing cylinder reduces waste and lowers the total carbon footprint of the upgrade.
• Cost Efficiency: You avoid the expense of purchasing a new tank and the additional plumbing required for a full replacement.
• Flexibility: It is ideal for homes where the cylinder is located in a hard-to-reach internal cupboard, but you want to move the heating work to an outdoor unit.

Typically, a retrofit system costs between $7,500 and $11,000, including GST. This is roughly the same as an integrated system, though retrofitting can save you significant money compared to a full split system replacement.

• Cost-Effective: It allows you to access premium technology like Panasonic or Rinnai while re-utilising your existing cylinder.
• High Value: You are investing in advanced heating components while extending the life and value of your current infrastructure.
• Long-Term Savings: By reducing water heating costs by up to 75%, the system pays for itself through significantly lower monthly power bills.

Usually between 6 and 8 hours. Our goal is to ensure minimal disruption so you have hot water available by the evening.

• The Process: This includes mounting the outdoor unit, running the water lines to your cylinder, and electrical commissioning.
• Minimal Mess: Because we are working with your existing infrastructure, there is often less "deconstruction" required inside the home.

Yes, our systems use advanced R744 (CO₂) and R290 refrigerants. These are specifically proven for NZ winters and are engineered to perform in freezing temperatures without relying on expensive backup elements.

• Exceptional Performance: Unlike older models, these refrigerants allow the system to extract heat from the air even in sub-zero conditions.
• Panasonic CO₂: Performs reliably down to low ambient temperatures while remaining exceptionally quiet at 37dB.
• Rinnai HydraHeat Split: Specifically designed for NZ outdoor conditions to ensure fast recovery and high efficiency during the coldest months.

In some cases, savings of up to 75% are possible, depending on your current system, usage habits, and household size. A retrofit system is vastly more efficient than the "standard" electric element currently inside your tank.

• Efficiency Gains: For every 1kW of electricity used, these systems typically return 4kW+ of heat. 
• Comparison: Standard electric cylinders are roughly 100% efficient; our retrofit systems operate at 400% to 500% efficiency on average.

Yes, they are specifically designed to work as a retrofit, and the units come with good warranties. Because the "working parts" are located in the outdoor unit, they are easy to service and maintain.

• Warranty: We prioritise brands like Panasonic and Rinnai that offer strong national service networks and multi-year warranties.
• Maintenance: A simple annual check-up ensures the system remains optimised for 15–20 years of service.
