Endless hot water, sized to your household
Choosing between storage and continuous flow starts with how your household actually uses hot water, not with the brochure. Ring (02) 9072 0528 and we will talk it through, or browse the whole silo at hot water systems.

Gas systems we fit and look after
We size, supply, install and service the full range of gas hot water plant, and the choice between them shapes your running costs for the next fifteen years:
Continuous flow units
Continuous flow units heat water only as it passes through, mounting on a wall and freeing floor space, which suits the compact layouts near the station precinct, and we size flow rate to bathrooms and outlets before quoting: hot water installation covers the full process.
Gas storage tanks
Gas storage tanks hold a heated volume ready for heavy simultaneous use, fitting family homes that run two bathrooms, and we match tank capacity to household size so nobody draws the last shower cold.
Electric-to-gas conversions
Electric-to-gas conversions replace ageing electric tanks with efficient gas units, running new supply lines, flues and compliance plate work where needed, and many owners near the hospital precinct make the switch when their old element finally fails: hot water replacement covers end-of-life decisions.
Older gas line upgrades
Older gas line upgrades bring heritage supply runs up to current standards before a new unit connects, pressure testing every joint and certifying the work, and any suspicion of a leak belongs with gas leak response first.

Where gas systems fail
A pilot that will not hold
A thermocouple wears out, a drafty flue blows the flame out, or a clogged pilot jet starves it, and each fault has a different fix, so we diagnose the true cause before replacing parts the system never needed in the first place.
Burners running rough
Rust flakes, insects and scale build up inside burner assemblies over years of service, producing yellow flames, soot and slow recovery, and a proper strip, clean and combustion check usually restores full output for a fraction of replacement cost.
Weeping valves and rust
A pressure relief valve dripping steadily, or rust weeping from the tank base, signals a system near the end of its life, and we set out repair versus replacement honestly, routing repairable faults to hot water repair and end-of-life cases toward renewal.
Why the decision deserves more than a guess
Gas systems are a fifteen-year commitment: the wrong size, the wrong location or an unassessed supply line locks in problems for the life of the unit.
- Comfort, every day A correctly sized system keeps showers hot through a household's morning peak, while an undersized continuous flow unit or a tired tank disappoints the third person in line every single day.
- Safety, certified Gas work done properly ends with compliance certificates and a combustion test, protecting your household and your paperwork trail, because a shortcuts-and-guesses gas install is the one plumbing risk nobody should carry.
- Running costs, for years Gas hot water generally costs less to run than electric storage, but only when the unit, the flue and the supply line are matched correctly from day one, which is exactly what we do.
How it works
The process, step by step
- 01
Call and tell us
Ring (02) 9072 0528 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
Fit, test and commission
We install the agreed system, assessing heritage supply lines first where the property needs it, then run a full combustion test, set the delivery temperature, and walk you through operation before we pack up, with compliance certificates issued on the spot.
- 04
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 St Leonards
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 St Leonards 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
Where else we work
Our crews cover the whole lower North Shore patch beyond this ridge, including Crows Nest, Wollstonecraft, Naremburn, Artarmon and Greenwich, and the difference is simple: fixed written pricing before work begins, licensed gas fitting with certificates on completion, and stocked vans that finish most jobs on the first visit.

Gas hot water questions from St Leonards locals
How long does a gas hot water system usually last?
A well-maintained gas storage tank typically serves a household for ten to fifteen years, while continuous flow units often run longer because they heat water only when a tap is actually open.
Is continuous flow better than a gas storage tank?
Continuous flow suits compact households wanting endless hot water from a wall-mounted unit, while storage tanks better serve families running several outlets at once, and we size the choice to your actual usage.
Can you replace a gas system inside an apartment tower?
Yes, we replace gas units across the local towers regularly, coordinating building-manager access, isolating the correct riser and protecting common corridors so the swap happens inside one booked window with minimal disruption.
Do older cottages need gas line upgrades before a new system?
Many brick cottages on the southern streets retain original gas fittings, so we inspect the run first and bring it to current compliance standards before connecting any new hot water unit.
How quickly can a plumber get to me?
We prioritise hot water faults as they happen, our vans are stocked for the common gas jobs, and a licensed plumber answers the phone whenever you call, day or night.
What warranty covers the work?
Every job is backed by our Lifetime Labour Warranty, so if the workmanship is not right we come back and make it right, with no questions and no cost to you.
