We work on all major hot water heat pump brands, delivering fast diagnostics and effective solutions to keep your hot water running smoothly.

Professional Hot Water Heat Pump Installation

Choosing the right hot water heating system is an important investment decision. Our knowledgeable team will assess your household’s hot water needs and recommend the ideal heat pump solution that delivers long-term savings and reliable performance.​

How Hot Water Heat Pumps Work

Unlike traditional electric cylinders that generate heat directly, hot water heat pumps extract warmth from the surrounding air and transfer it to your water. The system uses electricity only to power the compressor and fan rather than heating elements, making it approximately 3-4 times more efficient than conventional electric water heaters. This innovative technology means you receive the same hot water comfort while using a fraction of the energy.​

Significant Benefits for Your Home

Consistent, reliable hot water
Servicing and repairs ensure your system heats water efficiently and consistently, reducing temperature fluctuations or unexpected outages.

Improved energy efficiency
A well-maintained system uses less electricity to heat water, helping reduce ongoing power costs.

Prevents costly breakdowns
Early maintenance and prompt repairs stop small issues from turning into major faults like compressor failure or leaks.

Extends the lifespan of your system
Regular care reduces strain on key components, helping your heat pump last longer and operate more reliably.

Safe, worry-free operation
Professional servicing identifies issues such as electrical faults, refrigerant problems, or failing parts, ensuring your system runs safely and correctly.

Professional Installation Process

Proper installation by qualified professionals is essential for optimal performance and longevity. Our certified plumbers and electricians follow strict installation standards to ensure your system operates safely, efficiently, and meets all New Zealand building code requirements.

The installation process begins by identifying the optimal location near your existing hot water cylinder for the compact indoor unit. Copper refrigeration pipework and interconnecting wiring are then run from this unit to a small outdoor unit, typically routed through the roof space. Once positioned, the indoor unit is professionally plumbed into your existing hot water cylinder using dedicated hot and cold water pipework. The system is then completed with electrical wiring carried out by a certified electrician, including all required safety protections. Tank sensors and control systems are installed to ensure accurate operation and efficient performance. Finally, the system undergoes thorough commissioning, including leak testing, calibration, and full operational setup.

Regular Hot Water Heat Pump Service & Maintenance

Regular professional servicing is essential to maintain your hot water heat pump’s efficiency, protect your warranty, and extend the system’s lifespan. We recommend servicing your hot water heat pump every 1-2 years depending on usage and environmental conditions.

Comprehensive Service Includes

  • Heat exchanger coil cleaning to maintain maximum heat transfer efficiency and prevent buildup
  • Refrigerant level checks and leak detection to ensure optimal system performance
  • Electrical inspection including terminals, wiring, and safety controls
  • Fan motor inspection and lubrication to ensure smooth, quiet operation
  • Condensate drain clearing to prevent blockages that can cause water damage
  • Complete system performance testing to identify any efficiency issues or potential problems

Why Regular Servicing Matters

Professional maintenance prevents unexpected breakdowns during times when you need hot water most. Regular servicing ensures your system continues operating at peak efficiency, which translates directly into lower power bills month after month. Neglecting maintenance can lead to dirt accumulation, reduced performance, higher energy consumption, and potentially costly repairs that could have been prevented.

Well-maintained hot water heat pumps can reliably provide efficient service for a number of years, making regular servicing a smart investment that protects your initial purchase and maximizes your long-term savings.

Between professional services, check your pressure relief valve every 2-3 months by briefly opening it to ensure water flows freely. Keep the area around your outdoor unit clear of vegetation, debris, and obstructions to maintain proper airflow. If you notice any unusual noises, reduced hot water supply, or increased energy bills, contact us promptly before minor issues become major problems.
