Gas storage
Simple to replace like-for-like in many older homes, with good recovery for busy households. Running costs depend on gas prices, and the tank loses some heat over time.
Continuous-flow gas
Heats water on demand, so it never runs out and takes up little space. It needs an adequate gas supply, and there can be a short delay before hot water reaches the tap.
Heat pump
Uses electricity very efficiently by drawing heat from the air. Works especially well with rooftop solar and suits households planning to go all-electric. It makes some fan noise and needs space outside.
How to decide
Consider household size, whether you have solar, plans to disconnect gas, where the unit can go and current rebates. We explain the options and running costs for your home. We are happy to compare options for your household and explain the likely running costs before you decide. Whatever you choose, have it installed by a licensed plumber with a compliance certificate.
Hampton Park soil and pipes
Hampton Park sits on heavy grey clay over sandier ground towards Lyndhurst, and that clay swells in a wet winter and shrinks and cracks in a dry summer. The older homes west of Hallam Road were mostly connected with earthenware sewer pipe in short lengths, and every joint is a place for roots to get in once the ground moves. Galvanised steel water pipe from the same era rusts from the inside, narrowing the bore and eventually leaking. On the newer estates, PVC drains are tougher, but trenches that were not compacted properly can settle and leave dips that hold grease and paper. We use a drain camera and pressure testing to see what is actually happening rather than guessing.

Questions on this topic
Why do plumbers not recommend tankless water heaters?
Some plumbers are wary because of gas supply needs and the short delay before hot water arrives. For many homes, they work very well.
Are there rebates for heat pumps?
Rebates have been available in Victoria; we check what applies when we quote.
