Your Instant Hot Water Questions Answered

Yes! These systems heat water as it flows through—no waiting for a tank to refill.

Want to upgrade? We'd love to make it happen. In our initial callout, we’ll assess your existing setup and advise on the best solution moving forward. With decades of experience across plumbing and gas installation, there's no job that is too difficult for us to handle.

Yes—we cover the entire metro area and surrounding suburbs from Salisbury to Seaford, and can be onsite in 30 minutes for emergencies.

Gas instant systems generally deliver higher flow rates, making them better suited to family homes or properties with multiple bathrooms. They’re also more energy-efficient during peak usage and typically cost less to run over time.

Electric systems, on the other hand, are a good choice for smaller households, apartments, or where gas isn’t available. They’re compact, easy to install, and work well when space and demand are minimal.

Our recommendation?
If you have access to mains gas, we usually suggest a gas instant system for better performance, reliability and cost-efficiency. But every home is different—our plumbers will assess your usage and setup to recommend the right fit.
