A real person answers, day or night
Gas delivery that keeps up with a full house
A household of four running morning showers, the dishwasher and the washing machine before school asks a lot of a cylinder, and gas recovery is built for exactly that load. Call (02) 9072 0520 to talk it through.
Why gas suits the homes on this ridge
- The housing stock grew up with gas Interwar and mid-century detached houses from the 1915 Halloran-era subdivisions were largely built when town gas, then natural gas, reached the Upper North Shore, and many still carry the line.
- Ridge winters run harder The elevated ridge-top position gives noticeably cooler nights and crisp winters compared with the coastal plain, so hot water demand runs harder for longer each year.
- Units here run long past their years Long-held, owner-occupied family homes commonly keep hot water units well beyond service life, so when a gas system finally gives up, the swap needs to be quick, correctly sized and compliant from day one.
What we do with gas hot water
Our gas work covers the full life of a system, from first install through years of servicing to the eventual replacement, all under licensed gas workmanship.
Supply and installation
We size a gas storage or continuous flow unit to your household's real demand, position it to code, and commission it fully, with old units removed and every connection certified the same day.
Diagnostics and servicing
Pilot lights, thermostats, valves and burners all fail predictably with age, and we diagnose the true fault with proper instruments before replacing components, often restoring an older unit for years more service.
Gas line work and compliance
New gas points, line upgrades for higher-demand units, leak tracing and certification sit within our licence, so a system upgrade never stalls waiting for a second trade to arrive on site.
Tempering and temperature control
Safe delivery temperatures are a legal requirement, especially in homes with young children, and we fit, test and replace tempering valves so every tap runs compliant water without scald risk.
Efficiency upgrades
Older gas cylinders can chew gas compared with modern continuous flow or high-efficiency storage units, and we model the running difference honestly so an upgrade is never sold on guesswork.
The replacement rhythm in an established suburb
- The 1960s to 1980s brick and brick-veneer wave These homes often still carry their second or even third gas cylinder, installed decades ago and quietly rusting on an external wall.
- The newer townhouse pockets near the railway station These more commonly run compact continuous flow units tucked into cupboards or on internal walls, where ventilation clearances and condensate drainage decide what can fit.
- The earliest fibro and weatherboard cottages Here the unit's position was often dictated by a tight old laundry rather than by what the code would prefer today, and we work with all three situations weekly.
Common gas hot water problems we fix
Water running lukewarm or cold
A failing thermostat, a worn thermocouple or a pilot that will not hold each stop the burner doing its job, and we test each with instruments rather than guessing, then fix what genuinely failed.
Rusty or discoloured hot water
Brown or rusty water from the hot taps usually means the tank lining has failed and the anode is spent, which flags a unit in its final stretch, and we give you straight options.
Leaking from the tank base
Water pooling beneath the cylinder points to internal tank corrosion rather than a fitting fault, and because that cannot be sealed, we walk you through replacement pricing on the spot.
Rumbling or knocking noises
Sediment settling on the tank floor heats unevenly and rumbles as bubbles force through it, shortening tank life, and a service flush, where the unit warrants it, buys years back.
Why sorting it early matters
- Cold mornings arrive without warning Tanks rarely fail on a convenient day, and a sudden loss through a ridge winter turns a planned upgrade into an urgent one, usually at the worst possible hour.
- Gas waste compounds quietly An inefficient or poorly tuned unit burns more gas every single day it runs, so the cost of delay lands on your quarterly bill long before the tank dies.
- Safety sits above comfort Gas connections, flues and temperature controls all carry compliance obligations, and work done unlicensed or left unfixed puts your household, not just your budget, at risk.

Size, fit and certify the unit
We match a gas system to your household's actual peak demand, set it to code with correct clearances and fluing, connect it to the gas line, and test and commission it fully before certifying the installation for your records.

Why choose Your Plumber Asquith
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 Asquith 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.
That local stocking matters most on cold mornings, when a failed pilot light cannot wait a week for parts.
Where we work
Areas we service
Gas hot water work extends across North Wahroonga, Hornsby, Mount Colah, Waitara and North Turramurra, wherever established family homes need a system sized, serviced or swapped. The same licensed gas workmanship and fixed written pricing apply on every street we attend.
Good questions, straight answers
Gas hot water questions from Asquith locals
How long should a gas hot water system last?
Most gas storage units serve a household for eight to twelve years, and tank age, water quality and service history all influence where your unit sits in that range.
Is gas or electric better for a large family home?
For bigger households with high morning demand, gas recovery speed usually wins, though the honest answer depends on your connection, roof space and usage pattern, which we assess on site.
Can a leaking gas hot water tank be fixed?
A tank leaking from the cylinder itself cannot be sealed safely or durably, so the practical path is a new unit, and we price that option alongside any alternatives on the day.
Do you handle the gas compliance work too?
Yes, our plumbers are licensed for gas work, so isolation, connection, testing and certification of your new gas hot water system are all completed under the one licence and invoice.
How quickly can a replacement be installed?
Standard gas swaps are commonly completed the same day once the unit is confirmed, because stocked vans and established supplier relationships remove the waiting that turns a warm house cold.
Will a new gas system cut my energy bills?
A modern gas unit matched to your household size typically uses noticeably less gas than an ageing one, and we explain the expected running differences before you commit to anything. Comparing fuel types? Our pages on electric hot water systems and instant hot water systems set out the alternatives. Smelling gas right now? Follow our gas leak guidance immediately, or start at the hot water hub for the full picture, including hot water repair for faults worth fixing.
