Efficient Systems, Expert Installation
Every property has different hot water needs. Gas systems can be installed as instantaneous (continuous flow) units or as storage systems — each offering distinct advantages. Instantaneous systems heat water as you need it, making them ideal for families who want endless hot water without waiting. Storage systems, on the other hand, maintain a ready supply for immediate use across multiple outlets.
A professional installer will assess your home’s layout, water pressure and gas supply to recommend the most suitable system for your space. The result is a safe, efficient setup that provides reliable hot water and helps reduce energy bills year-round.
Gas installations must always be handled by licensed gasfitters to meet legal and safety requirements. Professional installation ensures correct ventilation, secure fittings and accurate temperature control. Regular servicing will keep your system running efficiently for years, reducing the risk of breakdowns and maintaining warranty coverage.
FAQ
Everything You Need To Know
Why should gas hot water installation be done by a professional?
Gas hot water installation involves handling pressurised systems and flammable gas lines, which require technical expertise and strict compliance with Australian standards. Licensed gasfitters ensure safe connections, proper ventilation and leak-free fittings. Professional installation also protects your warranty and ensures the system operates efficiently and safely.
How long does a gas hot water installation take?
In most cases, installation takes between two and four hours, depending on the unit type and property setup. Replacing an existing system is typically faster, while installing a completely new connection may take longer. A qualified gasfitter will test the system, check for leaks and ensure everything meets safety codes before completion.
Can I replace my electric hot water system with gas?
Yes — switching from electric to gas is a common upgrade for energy efficiency and faster heating. The process involves capping off the old electrical system, connecting the new gas line, and safely installing the gas unit. A licensed gasfitter will manage all components of the conversion to ensure compliance and performance.
