Tips for upgrading your hot water for efficiency, reliability and lower bill.
Upgrading your hot water system is one of the smartest ways to cut household energy bills while reducing your environmental footprint. Whether you’re considering a heat pump, solar hot water, or a 5-star gas system, there are excellent solutions available to suit your needs and budget.
Below, we explore different energy-efficient hot water technologies, their benefits, and real examples of customers who made the switch.
Why energy efficiency matters now
Hot water heating accounts for around 30% of household energy use. Choosing an energy-efficient system isn’t just about avoiding cold showers—it directly impacts your household budget and environmental footprint.
Key benefits of upgrading include:
- Lower utility bills.
- Reduced greenhouse gas emissions.
- A more reliable and consistent hot water supply.
- Potential access to Government rebates.

Heat pump hot water systems
A smarter way to heat water
Heat pumps are one of the most efficient ways to heat water because they draw heat from the surrounding air instead of generating it directly. Working like a reverse refrigerator, they transfer this heat into the storage tank, reducing electricity use by up to two-thirds compared to traditional systems.
The benefits of heat pumps
- Operates day and night, in most weather conditions.
- Uses ambient air temperature, not direct sunlight.
- Easy installation, no rooftop collectors required.
- Eligible for Government rebates.
Real-life case study : Bilgola customer
One of our Northern Beaches customers recently swapped their ageing solar system for a Rheem Solar Heat Pump. We installed the unit in the same position as the old tank, making the transition quick and cost-effective. The family now enjoys reliable hot water with lower running costs.
Why choose a Rheem heat pump
Rheem heat pumps are designed for Australian conditions, offering advanced features such as backup electric elements and frost protection. Models like the AmbiPower 280e also use low-GWP refrigerants, making them environmentally responsible. Backed by warranties of up to seven years on the tank, they are a durable and sustainable option for long-term savings.
Solar hot water systems
Solar hot water remains one of the most sustainable ways to heat water, using free energy from the sun to significantly reduce household running costs. There are two common designs:
Rooftop solar hot water systems
This is where both the solar collectors and the storage tank are mounted on the roof. These systems are highly effective but can be heavier and more expensive to install or replace.
Split solar hot water systems
This type has solar collectors positioned on the roof, while the storage tank sits at ground level. This design reduces roof load, is easier to maintain, and is often preferred for larger or heavier tanks.
When solar is best suited
Solar hot water is ideal for most Northern Beaches households with:
- Good roof orientation (north-facing in Australia) with minimal shading.
- Medium to large families with high daily hot water usage.
- A long-term focus on reducing household bills and carbon emissions.
- Access to Government rebates to help offset the higher upfront installation cost.
Even though solar systems may require an electric or gas booster in cloudy weather, they provide excellent long-term savings and remain one of the most eco-friendly choices available.
Energy-efficient gas hot water systems
Gas remains one of the most popular hot water options due to its reliability and efficiency. Modern 5-star rated systems provide excellent performance while keeping costs under control.
Real-life case study : Belrose customer
A customer in Belrose noticed wet patches on their ceiling caused by a leaking rooftop solar system. After 25 years of service, the solar unit was no longer efficient, and repairs weren’t practical. The customer opted for a Rheem 5 Star gas storage heater. We safely removed the old rooftop panels and tank before installing the new ground-level gas system, giving them reliable hot water without the high cost of replacing solar.
Real-life case study : Mona Vale customer
Another household in Mona Vale upgraded from an ageing electric water heater to a Rheem Stellar 360. The family was tired of cold showers and rising bills, so we installed a 5-star gas unit with a large 160L tank and a fast recovery rate of 200L per hour. This system is perfect for large households with multiple bathrooms.
Features of Rheem 5-Star Gas Systems
- 5-star energy rating for reduced running costs.
- Fast recovery to quickly replace hot water after use.
- Strong mains pressure for multiple taps and showers at once.
- Long-lasting performance backed by Australian manufacturing and warranties.
Government rebates and incentives
Both heat pumps and solar hot water systems qualify for rebates, while high-efficiency gas models may also attract incentives. These rebates can cover a significant part of the upfront cost, making energy-efficient upgrades more affordable than many homeowners expect.
MAKE THE SWITCH
We’re here to help you make the switch to an energy efficient hot water system, providing you with advice you can trust.
Before upgrading, we’ll check your eligibility for Government rebates, deduct the rebate amount directly from your purchase price, and ensure you maximise every possible saving.
If your hot water system is leaking, inefficient, or simply costing too much, now is the perfect time to upgrade. Whether you choose a Rheem heat pump, solar, or a 5-star gas unit, you’ll enjoy peace of mind, lower bills, and a reliable supply of hot water for years to come.
