Solahart Hervey Bay: Rooftop Solar Hot Water Systems

Solar hot water systems use roof-mounted collectors to absorb the sun's heat. In thermosiphon systems, as water heats up it naturally rises into the storage tank mounted above the collectors. This process continues throughout the day, providing you with free hot water from the sun. An electric or gas booster ensures you have hot water even during cloudy periods.

Open circuit systems circulate your actual water supply through the collectors. They're simpler and ideal for non-frost areas. Closed circuit systems use a special heat transfer fluid (Hartgard) that never freezes, making them perfect for frost-prone or harsh water chemistry areas. The heat is transferred to your water via a heat exchanger.

Solar hot water can reduce your water heating energy costs by up to 75%, depending on the system and your location. For most Hervey Bay households, this translates to $500-$900 in annual savings. The exact amount depends on your household usage, system type, and local conditions.

True north orientation is optimal, but Solahart systems can be effectively installed on roofs facing anywhere within 60 degrees of true north. If your roof faces east or west, we can adjust the collector angle to maximise performance. During your free assessment, we'll determine the best configuration for your home.

Standard systems come with a 5/5/5 warranty: 5 years on cylinder and collectors, 5 years parts, and 5 years labour. Free Heat models offer an extended 10/5/5 warranty with 10 years on the cylinder and collectors. This reflects over 70 years of trusted Australian manufacturing.

Yes! Significant rebates are available through STCs (Small-scale Technology Certificates) for eligible solar hot water installations. These rebates are deducted from your quote price, so you don't pay upfront and claim later. We handle all the paperwork for you.
