Hot water is one of those things you don’t think about until it suddenly disappears. A cold shower first thing in the morning, dishes piling up in the sink, or a system that gives up halfway through bath time – it’s never convenient. That’s where Lucas Plumbing & Gas Solutions comes in. We specialise in Rinnai hot water systems across Adelaide and our licensed plumbers know these units inside and out.
Rinnai is one of the most trusted names in hot water, but no system is indestructible. There are signs worth keeping an eye on. Maybe your hot water takes forever to come through, or the temperature swings from hot to cold without warning. You might notice water pooling near the tank, a pilot light that won’t stay lit, or strange noises coming from inside the unit. Sometimes the water itself gives the game away – rust-tinged, cloudy, or carrying sediment. These are all signals that your system is struggling. If you catch them early and call us in, repairs are usually straightforward. Leave them too long, and you could be up for a full replacement.

We offer a wide range of reliable Australian hot water systems—call us today for a quote.

Few things throw a household off balance like a hot water failure. That’s why we don’t just work nine-to-five and you can reach out to our hot water plumbers 24x7 - call us day or night and we will get a qualified plumber to you fast. From faulty thermostats to leaking valves and pilot light troubles – whatever the problem, we will diagnose it quickly and get your hot water flowing again.
Sometimes, repair isn’t the smartest move, and if your Rinnai system is old, inefficient, or breaking down every few months, replacement is usually the more cost-effective option. That’s where professional installation matters. We supply and install the full Rinnai range – gas, electric, solar, and heat pump systems – and we will help you choose the right unit for your household size, water usage, and budget. Our team removes the old system, installs the new one correctly, and tests everything thoroughly before we leave. It’s not just about getting it working – it’s about making sure it keeps working for years to come.

In Australia, they have built a reputation for designing systems that match our climate and lifestyle. Continuous flow units that never run out of hot water. Heat pump technology that cuts energy bills. Storage tanks that hold up under pressure. Their systems are built to last, and most come backed by generous warranties – five to ten years depending on the model. When you choose Rinnai, you are choosing reliability and efficiency, with the peace of mind that your investment is covered long-term.
Picking a hot water system isn’t a one-size-fits-all decision and can be confusing for any homeowner. A small household using minimal water doesn’t need the same capacity as a busy family home and then there are other factors to consider - gas and solar options can make a big difference to running costs, while electric or heat pump systems might be better suited to certain properties. Our job is to guide you through the options honestly and clearly, so you can make a decision that makes sense. We won’t push you toward the most expensive model – just the right one.
Don't waste your time and money on unreliable hot water. For fast hot water system repairs Adelaide-wide or a system replacement and advice on upgrading to a more efficient Rinnai unit, Lucas Plumbing & Gas Solutions is here to help.
