Why So Many Melbourne Hot Water Units Fail in February
Melbourne plumbers know the pattern. Through January the phones are quiet on hot water, then February hits and the calls pile up. There is a clear reason and a clear set of things you can do to avoid being one of those February call outs.
The Heat Wave Effect
February in Melbourne brings the hottest days of the year. The Bureau of Meteorology at https://www.bom.gov.au/ records most of our 40 plus degree days in late January and February. Mains cold water enters tanks warmer than usual, so storage units cycle less often but their elements still age. Older anodes, weakened thermostats and tired pilot assemblies all show up under that stress.
Low Demand Reveals Existing Faults
During summer most households use less hot water than they do in winter. A small leak that was masked by constant cycling now drips visibly. A pilot light that struggles to ignite during heavy winter use will simply give up in summer when it has been idle for days at a time. Energy Safe Victoria at https://esv.vic.gov.au/ has guidance on safe gas appliance use during heatwaves.
Electrical Storms and Power Surges
February thunderstorms are notorious for power surges that knock out element thermostats. After a big storm, Melbourne electricians and plumbers both see a spike in element and igniter failures. Surge protection and a quick check of your switchboard after a storm helps. The Australian Energy Regulator at https://www.aer.gov.au/ has information on storm related outages.
Holiday Returns and Sudden Hot Water Demand
Families returning from holidays in early February switch on systems that have sat unused. Long idle periods cause sediment to settle and burner trays to clog. A short flush and a check before peak demand starts again can avoid a fail.
Things You Can Do Now
Flush a few litres from the relief valve, check for damp patches under the tank, listen for unusual rumbling sounds, and book a service if your unit is more than seven years old. Sustainability Victoria at https://www.sustainability.vic.gov.au/ explains rebates if your replacement is going to be an upgrade to a heat pump or solar system.

FAQ
Is February really the peak failure month? Yes, our service records consistently show February as the highest call out month for hot water across Melbourne.
Should I replace before failure? If your tank is 10 years or older, planned replacement saves on after hours fees and water damage.
Does the size of the tank matter? Yes. An undersized tank in a heatwave is worked harder by family showers and dishwasher cycles.
Will insurance cover a sudden failure? Most policies cover sudden damage but not gradual deterioration. The Insurance Council of Australia at https://insurancecouncil.com.au/ has plain English guidance.
