A bit of history

Vulcan's about page says the brand was best known in the 1960s for oil heaters. Rheem Australia bought it from Australian Consolidated Industries in 1984.

Today Vulcan says its gas and electric water heaters are all made in Rheem owned and operated factories.

Where a Vulcan can go

Vulcan says its heaters can be installed on an approved base against a wall, or recessed into a wall cavity. Its electric range can go indoors or outdoors.

If your old heater is recessed, measure the cavity before you choose a replacement of any brand.

Same again, or something different?

An electric storage heater is the simplest swap for an old electric one. If you'd like an electric alternative, ask the plumber to price a heat pump too.

A gas Vulcan in Victoria is a different story. Once a gas heater in an existing Victorian home wears out on or after 1 March 2027, its replacement has to be efficient electric. While it still works, it can be repaired. Check the current rules when the time comes.

Ask your plumber

  • Is a like-for-like Vulcan still the right size for us?
  • Will the new heater fit the same base or wall cavity?
  • Is this a job for a plumber, an electrician, or both?
  • Can I read the cylinder warranty conditions for this model before you order it?

Service

Vulcan says its heaters can be serviced by most plumbers or electricians. That makes a repair easier to book, but check that whoever opens it up holds the right licence for the work.

What we would do

If a Vulcan has served you well and still fits your plans, replacing it with the same type is reasonable. Before you do, get one alternative quote, especially in Victoria with gas. A plumber who specialises in hot water can measure the space and give you both options.
