How much does Hot Water & Gas cost in Melbourne? (2026 price guide)
A hot water system replacement typically costs $1,200-$3,500 installed, varying by system type - electric storage systems are usually cheapest, while heat pump and solar hot water systems typically run $2,500-$5,500. Gas fitting work, such as connecting a new gas appliance or running a new gas line, typically costs $200-$800 depending on distance and complexity.
Cost is driven by hot water system type and size, whether it's a like-for-like replacement or requires new pipework, gas versus electric, and any compliance requirements. Emergency hot water system failures often need same-day replacement, which can add a premium.
Only licensed gas fitters can legally work on gas hot water systems, so always check licensing, and ask about running costs of different system types, as a pricier system upfront can save money over its lifetime.
