Frequently Asked Questions

How much does a solar hot water system cost in Sydney?

Costs vary depending on the size of your property, the system you choose, and whether installation involves replacing an old unit. On average, a solar hot water installation has a higher upfront cost compared to traditional systems.
The good news is these systems often pay for themselves over time. With energy savings and potential solar hot water rebates in NSW, you’ll see reduced bills and long-term value. We provide clear, upfront pricing so you know exactly what your solar hot water system cost will be with no hidden fees.

Is solar hot water worth it for my home?

For many households in Sydney, solar hot water systems are a smart long-term investment. With plenty of sunny days, the system can supply most of your daily hot water needs while cutting back on electricity or gas reliance.
Beyond reducing bills, solar hot water can increase property value and help you live more sustainably. Our team of northwest Sydney experts can assess your property and guide you on whether solar is the right choice for your home.

Do solar hot water systems work on cloudy days?

Yes, modern solar hot water systems are designed with backup boosters—either electric or gas—that keep your hot water running even during extended cloudy or rainy weather.
This means you’ll get the benefit of renewable energy most of the time, while always having a reliable fallback. Our licensed gas plumbers will recommend the best solar hot water system for your family’s lifestyle and needs.

Are there government rebates for solar hot water in NSW?

Yes, NSW homeowners may be eligible for rebates or incentives that help reduce the upfront cost of solar hot water system installation. These programs encourage households to adopt energy-saving hot water systems.
At In House Plumbing, we stay up to date on the latest government offers and can guide you through the process, ensuring you receive all available savings. This makes choosing a renewable hot water solution even more affordable.

How long does a solar hot water system last before replacement?

With regular solar hot water maintenance, most systems last 10–15 years or more. Scheduling servicing helps extend lifespan, improve efficiency, and avoid costly breakdowns.
When it’s time for a solar hot water replacement or upgrade, we make the process straightforward and stress-free. Our plumbers provide expert advice, fast installation, and minimal disruption, so you can keep enjoying the benefits of reliable, sustainable hot water.
