Why gas is still the natural choice for so many local homes
Gas heats water hard and fast at a low running cost, which is why it suits everything from a busy family cottage to a high-rise riser. Call (02) 9072 0502 and we will match a unit to your connection.
Gas hot water in the apartment blocks
The post-2000 towers around the station handle gas in two very different ways, and knowing which yours uses shapes the whole job.
Central gas plant
Individual gas units
Gas systems we work with
Gas hot water comes in a couple of shapes, each with its own strengths, and part of the job is steering you to the one that fits your home, so here is the range:
Gas storage tanks
Holding a reserve of heated water for the morning peak, a gas storage tank recovers quickly between draws and rarely falters when several taps open at once, which suits a busy family house well.
Continuous flow gas
Firing only when a tap opens, a gas continuous flow unit never empties, frees a cupboard in a compact apartment and delivers endless hot water, provided the gas line behind it can serve every outlet you open.
Sizing and flow
Because an undersized gas unit loses temperature as soon as a second shower starts, we size on your peak draw and the number of bathrooms, so the system clears the household's busiest hour without a stumble.
Certified connection
Every gas job we finish is pressure-tested for tightness, fitted with the correct flue and tempering valve, and signed off with the compliance certificate, so the heater runs safely and your paperwork trail is complete.
Natural gas in the older houses
Along Botany Road, past the Mascot Hotel and the semis behind it, many period houses have long been connected to the natural gas mains that reach this part of the suburb.
Gas already at the door

Common gas hot water faults
Burner will not light
When a gas heater clicks but fails to fire, a dead igniter, a fouled burner or a starved gas line is usually to blame, and clearing or renewing that part brings a clean flame back for good.
Pilot keeps dropping
Should the pilot light then go out soon after, a tired thermocouple or a gas supply issue is the common cause, and swapping the component or clearing the line settles the flame so the burner stays lit.
Not enough hot water
If a gas unit runs cold partway through a shower, it is usually too small for the household or fed by a struggling gas line, so we check the demand and the supply before deciding on the right cure.
Why the right gas system pays
Choosing and sizing a gas heater well is not just about hot showers today, because the wrong call shows up on every bill and every busy morning for a decade, so it is worth getting right:
- Low running costs Gas heats water for less than an electric tank across the year, so a well-sized unit keeps the bills down across its long service life. That saving compounds in a busy household.
- Endless or ample supply A continuous flow unit never runs dry and a right-sized tank clears the morning rush, so nobody near the airport starts a shift on a cold shower. The household stops rationing hot water.
- Safe and compliant A certified gas install with a proper flue and the right valves protects the home and its paperwork. Cutting corners on gas is never worth the risk it stores up.
How it works
How a gas system goes in, step by step
- 01
Call and tell us
Ring (02) 9072 0502 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Connect and fire up
The moment it's approved, we connect the unit to the gas line, pressure-test the run for tightness, fit the flue and tempering valve, then fire the burner and tune it so the system delivers steady heat safely.

Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Mascot
The system may run on gas, but four commitments never change here.
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Mascot works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
Neighbourhoods we cover
We take the same gas-qualified service to Botany by the bay, Rosebery, Eastlakes on the low catchment, Wolli Creek beside the river and Tempe across the canal, all reached by the same local team.
Good questions, straight answers
Gas hot water questions in Mascot
Is gas hot water cost-effective to run?
Generally yes, because gas heats water quickly at a lower running cost than standard electric storage, which is a big reason so many houses and apartments on the gas mains here stick with it.
Can you work on the central gas plant in an apartment building?
Yes, we service central gas plant that feeds a whole building as well as individual unit heaters, coordinating access and approval with the owners corporation before any work on common property begins.
Should I choose a gas storage tank or continuous flow?
It depends on your space and demand, since a storage tank handles heavy simultaneous use while a continuous flow unit gives an endless stream and frees a cupboard, and we help you weigh the two.
Do I need a natural gas connection for a gas hot water system?
You need either natural gas at the property or a bottled LPG supply, so where a house already sits on the mains a gas heater is usually the straightforward and efficient choice.
Do you certify the gas work?
Yes, we leak-test the gas run, install the correct flue and a tempering valve, then issue a compliance certificate once the finished system is safe to use and your documentation is in order.
What does gas hot water advice cost up front?
Only your time, because the visit is $0, we assess the connection and set the gas job figure in writing first, and you owe nothing unless you choose to proceed.
