Solar Hot Water Systems

Solar hot water systems are an eco-friendly and cost-effective option for households in sunny regions like Penrith. These systems harness the sun’s energy via rooftop solar panels or integrate with existing solar power systems to heat your water.

Why choose solar hot water? 

  • Slash your energy bills: Once installed, solar systems reduce your reliance on the grid, cutting long-term energy costs.
  • Lower carbon footprint: Solar hot water produces zero emissions during operation.
  • Energy security: Less dependence on traditional power sources helps buffer you against fluctuating energy prices.
  • Government rebates: Many homeowners qualify for state or federal incentives when upgrading to solar.
  • Added property value: Homes with sustainable features are often more attractive to buyers.

Is solar right for you?

Heat Pump Hot Water Systems

Heat pumps work like a reverse refrigerator—drawing heat from the air to warm your water. They’re perfect for homes without rooftop access or in cooler, shaded environments.

The benefits of heat pump hot water

  • Energy savings: Heat pumps use significantly less electricity than traditional systems—up to 65% less in some cases.
  • Solar rebate eligibility: You may still qualify for renewable energy incentives, even without solar panels.
  • Simple installation: Often installed in place of an existing electric unit using existing plumbing.
  • All-weather performance: Effective year-round, regardless of sunshine.

Heat pumps are an excellent choice for eco-conscious families, especially when paired with solar panels for maximum efficiency.

Gas Hot Water Systems

Gas hot water systems are known for their fast heating and reliability. They’re available in two main types: instantaneous (continuous flow) and gas storage.

Instantaneous Gas Hot Water

These systems heat water only when you need it, without storing it in a tank.

The benefits of instantaneous gas hot water

  • Endless hot water: Perfect for large households or high usage.
  • Space-saving: Wall-mounted units fit neatly in tight spaces.
  • Highly efficient: Only uses energy when hot water is required.

Gas Storage Hot Water

These systems heat and store water in an insulated tank, ready for use throughout the day.

Features of gas storage hot water

  • Quick recovery time: Heats water faster than many electric models.
  • Reliable supply: You’ll have hot water even during blackouts.
  • Durable design: Built for long-term performance.
