As energy prices continue to climb, many households are looking closely at where their money is going. One of the biggest contributors often flies under the radar. Hot water.<\/p>\n

For most homes, heating water is one of the largest ongoing energy expenses, yet it is rarely questioned or reviewed.<\/p>\n

Powrhouse founder Tim Johnston said recent analysis of his own household highlights just how significant that cost can be.<\/p>\n

\u201cWe tracked 12 months of bills before and after switching systems, and the difference was clear,\u201d he said.<\/p>\n

Mr Johnston replaced a gas hot water system with a heat pump<\/a> at his home in early 2025. Before the upgrade, the household was using 14,398 MJ of gas each year purely for hot water.<\/p>\n

At current rates of around 4.92 cents per MJ, that equates to roughly $705 annually.<\/p>\n

\u201cWhen people see that number, it\u2019s often a surprise. Hot water is a major part of the energy bill,\u201d he said.<\/p>\n

After installing the heat pump, gas usage dropped to zero. Electricity usage increased slightly, by about 437 kWh across the year, adding roughly $120 to the electricity bill.<\/p>\n

The result was a net saving of about $580 annually.<\/p>\n

 <\/p>\n

\u201cHeat pumps are incredibly efficient, so the increase in electricity is relatively small compared to the gas savings.\u201d<\/p>\n

The figures are based on a family of four with moderate hot water use, including daily showers and regular baths.<\/p>\n

Savings will vary depending on household size and habits, but the underlying takeaway is consistent. Heating water carries a real and often underestimated cost.<\/p>\n

\u201cAs gas prices continue to rise, that cost is only going one way,\u201d he said.<\/p>\n

For households considering an upgrade, installation costs for heat pump systems typically range from $1,500 to $2,000, with many recouping the investment within a few years through lower running costs.<\/p>\n
