Hot Water Systems Gladesville | Repairs & Replacement

A property question, not a suburb one

The diagnosis is consistent everywhere. Sydney's water is soft, so a storage tank is protected by a sacrificial anode that corrodes so the steel does not, and once it is spent the tank corrodes instead. That or a failed element is most of what we attend.

What is not consistent here is what should replace it. Gladesville's housing spans a wide range of ages, because land came out around a large institutional holding in stages rather than in a single release.

So whether gas reaches you, what space the current unit occupies, and what the house was originally set up for all vary from street to street and sometimes within one.

That makes a generic recommendation close to useless. We look at what is actually there, then tell you what genuinely suits it, which is a different conversation from reading out a brochure.

Hot water on a Gladesville property

Soft water, so anodes rather than scale

Sydney's supply is soft. The anode protects the tank, and once it is gone the tank corrodes.

Replacing an anode costs a fraction of the tank it protects and is the most worthwhile thing to do to a unit worth keeping.

The right system varies by property

Gas availability, the space the current unit occupies, and what the house was set up for all differ considerably here.

That is a direct consequence of a suburb that developed in stages rather than in one push.

An older house may surprise you

Supply and position may have been arranged for a very different appliance.

It does not close options off. It means checking before ordering rather than after.

A leaking tank is not a repair

It is the end of that unit, and the damage while somebody decides exceeds the replacement cost.

Isolate it and treat it as urgent.

Age decides repair against replace

The compliance plate carries the date. A young system with a failed component is worth repairing.

One deep into its life with a leaking tank is not, and we would rather say so.

Working out which system your property will take

Most changeovers come down to type and size. In Gladesville there is a step before that, and it matters more than it does elsewhere: finding out what your particular property is already set up for, because the housing here spans a very wide range of ages and there is no suburb-wide answer to fall back on.

How long each type tends to last. The real figure depends on the workload, whether anyone ever looked at the anode, and whether the installer left it somewhere a service technician could actually reach.
Type	Where the heat comes from	Rough lifespan	Worth considering if
Electric storage	An immersed element warms a stored tank, commonly overnight	Around 8 to 12 years	No gas at the property, and the current cupboard already houses a tank
Gas storage	A burner beneath the tank maintains the stored volume	Around 8 to 12 years	Gas is connected and there is space for the tank plus its clearances
Continuous flow	Water is heated as it passes, with nothing held in reserve	Around 15 to 20 years	Gas is connected and you would rather have the cupboard back
Heat pump	Warmth is drawn out of the surrounding air into the tank	Around 10 to 15 years	There is outside room with air movement, well clear of where anyone sleeps
Solar with boost	Panels do the work, with a burner or element filling the shortfall	Around 15 to 20 years	The roof faces the right way, there is space on it, and the budget allows

Working out the size

Treat this as an opening position rather than a specification. Capacity governs how much you can take before it is gone, so the number that counts is how many people want hot water inside the same hour, not how many sleep in the house.

Continuous flow units are quoted in litres per minute instead of capacity. Nothing is held in reserve, so there is no point at which it empties mid-shower.
Household	Electric tank	Gas tank	Continuous flow
One or two people	125 to 160 L	90 to 135 L	16 L/min
Three or four	250 to 315 L	135 to 170 L	20 L/min
Five and above	315 to 400 L	170 L, or a pair	26 L/min
A tap a long way off	Lag the run as well	Lag the run as well	26 L/min

Diagnosed, and dated

We find the compliance plate and tell you the age before anybody mentions replacing anything.

Repairing a hot water system at a Gladesville property

Repair quoted first

If an anode, an element or a thermostat genuinely fixes it, that is the quote you get.

Step 04

Replaced properly if it is time

Old unit removed and taken away, the new one installed to standard and warranted in writing.

Hot water questions.

What Gladesville locals ask us before booking a plumber.

Ask us yours Licensed plumbing van covering Gladesville and the surrounding suburbs

No hot water at all. What should I check first?

On electric storage, look for a tripped circuit at the switchboard. On gas, check the pilot or ignition and that the supply is on. On anything, check whether an isolation valve got closed by somebody working on something else. If none of that explains it, ring rather than opening anything up.

Is it always the anode?

Very often. Sydney's water is soft, so the scale that finishes tanks in hard-water regions is not the story. Here the sacrificial anode corrodes away protecting the steel, and once it is spent the tank starts corroding. That or a failed element is most of what we see, and both are frequently repairs.

What system should I put in?

That is a property question here rather than a suburb one. Whether gas reaches you, what space the existing unit occupies and what the house was originally set up for all vary considerably across Gladesville, because the housing spans a wide range of ages. We would rather look than give you a generic recommendation.

The house is older than I thought. Does that change the options?

It can. An older house may have a supply and a position set up for a very different appliance, and what is behind the wall is frequently not what a modern install assumes. It does not close options off, it just means checking rather than ordering on the strength of a brochure.

The tank is leaking. Can it be repaired?

No. A leaking storage tank is the end of that unit, and the water damage while somebody decides usually outruns the replacement cost. Isolate it and ring rather than waiting to see whether it settles.

How long should a system last?

It depends on type, installation and whether the anode was ever looked at, so we will not put a number on a unit we have not seen. We will find the compliance plate, tell you the age, and give a straight view on whether repairing it is sensible.

What does hot water work cost in Gladesville?

Diagnosis and report is $120 to $250, credited against the repair if you proceed. An element or thermostat is $250 to $550. An anode replaced is $300 to $600. A storage replacement is $1,400 to $2,800 installed, with access priced in.
