At Waterworks Plumbing, we specialise in converting outdated or underperforming hot water systems to high-efficiency gas units. Whether you’re doing a full home renovation or simply sick of running out of hot water halfway through your shower, we can help you make the switch — cleanly, safely, and compliantly.

We typically install continuous flow gas water heaters from trusted brands like Rinnai and Bosch. These systems heat water only when you need it, saving power and delivering consistent temperature across multiple bathrooms or kitchens. They're also compact, freeing up valuable indoor storage space.

If you're upgrading from an electric cylinder, we handle everything — from pipework and gas certification to wall mounting and pressure balancing. We’ll inspect your home’s current system, advise on the correct unit size based on household use, and ensure that all work meets NZ building and gas safety codes.

Gas hot water systems are also great for rental properties and Airbnbs, where tenant turnover or large family stays can push hot water demand. We’ve done dozens of installations across Christchurch suburbs, and every time the feedback is the same: “Should have done it sooner.”

Our team takes the time to explain your options, outline costs clearly, and minimise disruption. We’ll coordinate with your gas fitter if needed, or refer one of our trusted partners. Best of all, we get it done right — and you’ll never have to worry about cold showers again.
