Solar hot water works differently to solar panels. The collectors on your roof capture heat from the sun and transfer it directly to the water in your tank, without converting to electricity first. Geelong gets a solid amount of sunshine across the year, and north-facing roofs across the region can be well suited to this setup. Most systems include a small electric or gas boost for overcast stretches, so you're not left without hot water when the weather turns. It's a practical option for households wanting to lower what they spend on energy for one of the home's biggest loads.

Solar Hot Water FAQs

Do solar hot water systems in Geelong need frost protection?
Geelong winters can produce overnight temperatures low enough to pose a risk to some solar hot water systems. Frost-tolerant or frost-protected systems are available and may be appropriate depending on your specific location and the system type. We can advise on the right configuration for your suburb and roof setup.
What roof orientation works best for solar hot water in the Geelong area?
North-facing roof sections generally give the best performance for solar hot water collectors in Geelong. That said, east or west orientations can still work effectively depending on the system size and your household's usage pattern. We assess each home individually before recommending a configuration.
How does a rooftop solar hot water system work?
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.
What's the difference between open and closed circuit systems?
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.
How much can I save with solar hot water?
Solar hot water can reduce your water heating energy costs by up to 75%, depending on the system and your location. For most Geelong households, this translates to $500-$900 in annual savings. The exact amount depends on your household usage, system type, and local conditions.
Do I need a north-facing roof?
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.
What warranty do Solahart solar hot water systems come with?
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.
Are there government rebates available?
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.
