At Curran, we know how important it is to have reliable hot water—whether you’re in Wollongong, Shellharbour, Nowra, Cronulla, Shoalhaven, Illawarra, or the Sutherland Shire. As Thermann’s trusted local partners, we bring you the best hot water systems on the market, along with expert installation, repairs, and advice.
Hot water systems come in different shapes and sizes, but they all do one thing: keep your showers warm and your dishes clean. Across the Illawarra, Shoalhaven, and Sutherland Shire, the most common types are electric, gas, solar, and heat pump systems, each with its own pros and cons.
Wondering how they work? Most systems heat water in a storage tank, while instant (tankless) systems heat water on demand. The right size for your home depends on how many people live there—typically, a 3-4 person household needs a 250–315L tank.
Energy efficiency matters too. Look for star ratings—the more stars, the lower your bills. If you’re unsure which system suits your home, we’re happy to help you compare.
Not all hot water systems are the same. Here’s a quick rundown:
Great for the South Coast’s sunny climate, with government rebates available.
As Thermann’s local experts, we recommend their high-efficiency systems—built to last and backed by great warranties.
Thinking about a new hot water system? Whether you’re upgrading an old unit in Kiama, switching from electric to gas in Miranda, or installing a Heat Pump in Berry, we handle full installations across the region.
Installation usually takes a few hours, and costs vary depending on the system type. In most cases, you won’t need council approval—but if you’re installing solar or gas, there might be extra steps. We’ll guide you through the process.
When should you replace your system? If your water’s not as hot as it used to be, you’re hearing strange noises, or your unit’s over 10-15 years old, it might be time for an upgrade.
No hot water in Helensburgh? A leaking tank in Ulladulla? We get it—it’s frustrating. Most hot water problems can be fixed quickly if caught early.
Common issues include:
To avoid breakdowns, we recommend yearly servicing, especially if you have hard water (common in areas like Dapto and Engadine). While some basic checks (like adjusting the temperature) are DIY-friendly, most repairs need a professional—that’s where we come in.
Hot water can be a big chunk of your energy bill, but there are ways to cut costs:
