Should You Service or Replace Your Vulcan Heater?
A Vulcan ducted gas heater that has run for 20 years or more is nearing the end of its serviceable life. What matters now is whether parts are still available, whether the heat exchanger remains safe and what a modern changeover would cost.
King & Sons still services any Vulcan heater Melbourne homes run, wherever genuine parts can be found. On a well-maintained unit, a service extends working life and keeps the heater operating safely. On a unit with a cracked heat exchanger or no remaining parts supply, we do not recommend continued operation.
Every Vulcan service visit includes a carbon monoxide test and a heat exchanger inspection. If the findings point to replacement, we cost a current-model system through a free on-site quote, typically from Brivis, Rinnai or Braemar, that connects to your existing ductwork. Most Vulcan changeovers finish in a single day.

Is it worth repairing an old Vulcan gas heater in Melbourne?
That comes down to parts availability and the condition of the heat exchanger. If parts can still be sourced and the heat exchanger passes a CO test, the repair is worth doing on most Vulcan old heater Melbourne installations. If the heat exchanger has cracked or parts are no longer obtainable in Australia, King & Sons recommends a replacement assessment and quotes a modern system during the same visit. We will not advise running any Vulcan gas heater in a Melbourne home with a failed heat exchanger.
What replaces a Vulcan ducted gas heater in Melbourne?

Each one fits an existing duct network and goes in within a day, and the Bonaire MB series shares its roots with the original Vulcan range. The right choice depends on your ductwork, ceiling void, zoning needs and efficiency goals, which King & Sons assesses on the day before quoting.
