Heat Pump Water Heater Systems

Discover the Future of Heat Pump Hot Water Systems Technology

Transforming Air into Comfort: Heat pump hot water systems are revolutionising how we think about heating water. By ingeniously using electricity to harness heat from the air or ground, these systems offer an eco-friendly and efficient alternative to traditional gas instant hot water system or electric water heaters. These versatile systems are not just for heating; they also provide a cooling effect in warmer weather, making them a year-round solution for temperature regulation.

Long-Term Savings and Low Maintenance: While the initial setup cost might be higher than conventional heaters, the long-term savings are substantial. Heat pump systems are known for their durability and require minimal maintenance, ensuring long-term financial and practical benefits for both homeowners and businesses.

About Our Range of Hot Water Heat Pumps

Introducing the Rinnai Enviroflo Heat Pump Range

A Leap in Efficiency and Design: The Rinnai Enviroflo range, designed and manufactured in Australia, represents the pinnacle of Electric Integrated Heat Pump hot water systems. Thanks to their versatile design and innovative controller, these systems are tailored to meet diverse installation needs across the country. The Enviroflo range can maximise hot water availability while using up to 75% less energy* compared to standard electric storage tanks.

Customisable and Robust: Available in various capacity sizes, the Enviroflo range can be equipped with magnesium or hard water anodes, allowing customisation to suit specific applications. A standout feature is the single-element boost, ensuring the system can handle high demand or cold ambient conditions, guaranteeing hot water all year round.

Durability and Environmental Consideration: Built to withstand the harsh Australian conditions, these tanks are designed to operate at water pressures up to 1000kPa, significantly higher than normal. Their lightweight design facilitates quick and safe installation with minimal environmental impact.

* Energy saving of up to 75% based on a Rinnai Enviroflo 250ltr/315ltr Heat Pump compared to a standard electric water heater of the same capacity during peak winter load in Zone 1 based on AS/NZS4234. Savings will vary depending upon your location (Zone 1-5), the type of water heater being replaced, hot water consumption and associated fuel tariffs.

Benefits of Heat Pump Water Heater Systems


1. Exceptional Energy Efficiency

  • Reduced Energy Consumption: Heat pump water heaters are remarkably efficient because they transfer heat rather than generate it. This process can be up to three times more energy-efficient than traditional electric resistance water heaters.
  • Lower Operating Costs: This efficiency translates into significant savings on electricity bills. Over time, the reduced operating costs can offset the higher initial investment in these systems.

2. Eco-Friendly Technology

  • Reduced Carbon Footprint: By utilising less electricity, these systems contribute to lower greenhouse gas emissions, making them a more environmentally friendly option.
  • Sustainable Heating Method: Many models use eco-friendly refrigerants, reducing their environmental impact.

3. Enhanced Safety Features

  • No Combustion Process: Unlike gas water heaters, heat pump systems do not involve combustion, eliminating risks like carbon monoxide poisoning and gas leaks.
  • Lower Surface Temperatures: The external parts of the heater are generally cooler, reducing the risk of burns and accidents.

4. Versatility and User Control

  • Multiple Operating Modes: Many heat pump water heaters come with different modes, allowing users to switch between efficiency-focused and high-demand settings.
  • Smart Features: Some models offer connectivity to home automation systems, enabling remote control and monitoring of the system’s performance and energy usage.

5. Dehumidification and Cooling Benefits

  • Air Quality Improvement: By extracting heat from the surrounding air, these systems can also dehumidify the space, which is particularly beneficial in damp areas.
  • Additional Cooling: The process of heat extraction can have a mild cooling effect on the surrounding area, which can be a welcome side benefit in warmer climates or during hot seasons.

6. Durability and Reliability

  • Longer Lifespan: Heat pump water heaters typically have a longer lifespan than traditional water heaters, owing to their less intensive heating process.
  • Lower Maintenance Needs: With fewer moving parts and no combustion elements, these systems often require less maintenance over their lifetime.

7. Financial Incentives

  • Rebates and Tax Credits: In many regions, homeowners can avail of rebates, tax credits, or other incentives for installing energy-efficient appliances like heat pump water heaters.
  • Increased Home Value: Installing an energy-efficient system can be an attractive feature for potential home buyers, potentially increasing the property’s value.

8. Consistent Performance

  • Steady Hot Water Supply: These systems are designed to provide a consistent and reliable hot water supply suitable for most households’ demands.
  • Adaptability: Heat pump water heaters can perform efficiently in various climates, making them versatile for different geographic locations.

Harnessing the Power of Air: Our air-sourced electric heat pumps work like magic, drawing heat from the air and transferring it to your water, akin to a refrigerator working in reverse. This method is three times more efficient than standard water heaters, leading to significant energy cost savings and reduced CO2 emissions. And the best part? You don’t need solar panels to reap these benefits.

Cost-Effective and Environmentally Friendly: Our heat pump hot water systems are budget-friendly and kind to the planet. By transferring heat instead of generating it, they consume less electricity, reducing energy bills and environmental impact.

Pricing and Benefits of Our Heat Pump Hot Water Systems


Affordable and Efficient: The prices of our heat pump water heaters vary depending on the model, but each one is an investment in both eco-friendliness and economy. Here are some key benefits:

  • Massive Running Cost Savings: Enjoy significant reductions in your energy bills over time.
  • Renewable Energy Production: Generate 3-5 times more renewable energy than the electricity consumed.
  • Eco-Friendly: Dramatically reduce your greenhouse gas emissions.
  • Easy Installation: No need for roof space or panels, and generous rebates are available for installation and purchase.
  • Effective in Low Temperatures: An electric assist feature ensures your water stays hot.

Considerations: While highly efficient, these systems may not be the best fit for areas with consistently low temperatures, as extended compressor run times in cold climates can impact the unit’s life expectancy and energy consumption.

More About Heat Pump Hot Water Heaters

Unlimited Hot Water Supply: A common question is whether these systems can run out of hot water. The answer is no. The system can continuously transfer heat to your water supply if there’s ambient air with heat energy.

Longevity and Efficiency: With proper maintenance, heat pump hot water systems can last many years. They are up to three times more efficient than traditional electric water heaters, making them a smart choice for sustainable living.

Sizing Matters: Choosing the right size for your heat pump hot water system is crucial. It depends on your household size, hot water usage, climate, and insulation. Consulting with a professional can help you select a system that meets your needs without wasting energy.
