Seaford grew in the 1950s and 1960s, drawn by affordable land and the beach, and if your home dates from then its heating may be due for a rethink. Living on Port Phillip adds sea air to the list near the foreshore. And with 23.2% of homes semi-detached or townhouses, the outdoor unit often ends up beside a shared fence.

Seaford, in three facts

A post-war beach suburb

Seaford, 36 km south-east of the CBD in the City of Frankston, grew during the 1950s and 1960s because it was affordable and close to the beach and Frankston.

Units next to houses

Of 7,191 occupied homes in 2021, 73.6% were separate houses, 23.2% semi-detached, terrace or townhouses and 2.5% flats.

A third rented

32.9% of Seaford homes were rented at the 2021 Census, 35.4% owned with a mortgage and 27.5% owned outright.

If your heating is an old gas wall or space heater

If your home or unit still relies on a gas heater in the living room, start there. Energy Safe Victoria says any gas heater can spill carbon monoxide, and open-flued heaters do it more easily than other types. It wants every gas heater serviced at least once every two years by a qualified gasfitter.

Better Health lists the warning signs: a yellow or sooty flame (unless it's a decorative log fire), a pilot light that goes out or pops and bangs when it lights, and soot stains around the heater. Since 1 August 2022, Victoria has banned the sale of new and second-hand open-flued gas heaters that can't shut down automatically.

When an old heater is due for replacement, a reverse cycle split in the living area gives you heating and summer cooling from one unit. See gas heater servicing in Melbourne and split systems in Melbourne.

If someone feels unwell while the heater's on

Energy Safe Victoria says to leave the house and get into fresh air, turn off gas appliances and open windows and doors, then call Nurse-on-Call, see a doctor, or dial 000 in an emergency. Keep the heater off until a qualified gasfitter has looked at it.

Close to the foreshore

Seaford's foreshore faces Port Phillip. The Galvanizers Association's AS 4312 guide puts the first 50 m back from a sheltered bay's shoreline in its C4 band and the next kilometre in C3. In that strip, ask for an outdoor unit with factory corrosion protection and read the warranty's coastal terms. Our coastal homes guide explains more.

What we'd do

Our take in Seaford

If an old gas space heater is still doing the work, we'd book a gasfitter to service and test it before winter. If it's past saving, we'd replace it with a reverse cycle split sized for the living area, with the outdoor unit placed away from the neighbour's bedroom and, near the beach, protected for salt air.

Let us know the job and your postcode, 3198. Local installers who do that type of work, with licences checked, get to see it, and your number goes only to the one who takes it on. If nobody near Seaford takes it on within 48 hours, installers elsewhere in Victoria may see it too.

Questions people ask

Is it worth repairing an old gas wall heater in a Seaford unit?
A gasfitter can tell you after a service and safety check. Better Health advises replacing any unflued heater more than 10 years old. For an older flued heater, weigh the repair against a reverse cycle split that also cools.
I smell gas near the heater. What do I do?
Turn the gas off at the meter only if it's safe, put out flames, don't touch electrical switches or devices, open up the house and keep people away. Ring the emergency line printed on your gas bill. For a fire, ring 000.
