Types of Hot Water Systems
Solar Hot Water Systems
Solahart’s solar hot water systems harness the power of the sun to deliver reliable, cost-effective hot water. We offer two main configurations:
- Roof-Mounted Systems: Both the solar collectors and storage tank are installed on the roof. Simple technology with no moving parts. Ideal for homes with sufficient roof space and structural support. Ideal for homes with sufficient roof space and structural support.
- Split Systems: The solar collectors are mounted on the roof, while the tank is positioned at ground level. Ideal for homes with limited roof space or where aesthetics are a priority.
Heat Pump Water Heaters
Heat pumps use ambient air to heat water, making them an excellent alternative in areas where solar may not be viable. Solahart Heat Pumps are designed for maximum efficiency, especially in cooler climates.
The new frost-tolerant model in the Atmos range, Solahart Atmos® Frost, is manufactured in Australia and engineered for versatility and resilience. It’s suitable for installation in nearly all Australian locations, including those with harsh water quality, cold climates, or tropical conditions.
Solahart Atmos® Eco 280 Heat Pump is also an Ultra Low GWP (Global Warming Potential) system, using R290 refrigerant to deliver superior environmental performance.
They’re also eligible for government incentives and help reduce your reliance on fossil fuels.
Evacuated Tube Collectors
Although Solahart pioneered evacuated tube technology, we now focus on flat plate collectors due to their durability, performance in Australian conditions, and ease of maintenance. If you're researching evacuated tubes, it’s important to understand why flat plate systems are a more cost-effective and reliable choice in most Australian homes.
Hot Water System Prices
Prices vary based on system type, household size, installation complexity, and the availability of incentives. While solar systems typically have a higher upfront cost, the long-term energy savings and rebates make them a smart investment.
