What do you need today
Choose the hot water service you need
Most people arrive here for one of four reasons. Pick the one that matches your situation and we will quote on that work specifically, not on a generic call-out.
Hot Water Installation
You need a new system supplied and fitted, whether that is a first install or an upgrade to a different type.
InstallationHot Water Repairs
No hot water, lukewarm water, a leaking unit, a pilot light that will not stay on or an error code on the display.
RepairsHot Water Replacement
Your current unit has reached the end of its life and you want it swapped over with minimal time without hot water.
ReplacementServicing & Maintenance
Scheduled servicing to keep a system running properly, including anode and valve checks on storage units.
ServicingWe supply and install — we don't sell units on their own
Sydney Hot Water Systems is a service business, not an online shop. Every system is delivered and fitted by our licensed team as one job, and your price is confirmed on the actual work. Add the systems you're interested in and send a quote request — there's no cart and no online payment.
Supply and install, one team
We provide the system and we fit it
Buying a hot water unit from one place and finding a plumber to install it is where most of the delay and cost confusion comes from. We hold stock of gas, electric, heat pump and continuous flow systems, and our own licensed team carries out the installation, so the quote covers the unit, the labour, the fittings and the removal of the old system.
That also means the person recommending the system is the person who has to install it. If a 170 litre gas storage unit will not fit the space you have, or your switchboard will not support an electric upgrade, you find out before you buy rather than on installation day.
Where a repair is the better option, we will say so. Replacing a unit that only needs a new element, thermostat or valve is not something we push.
System types
Which type of hot water system suits your property
The right system depends on what is already connected at the property, how many people use hot water and where the unit can physically sit. Here is how the four main types we supply and install compare.
Gas Storage
A tank that keeps water heated and ready. Suits homes already on natural gas with room for an external unit.
Gas systems and installation
Instant Gas & Continuous Flow
Heats water on demand with no tank. Good where space is tight or hot water use is spread through the day.
Continuous flow and installation
Electric Storage
The most common replacement where there is no gas connection. Available in sizes for one bathroom up to larger households.
Electric systems and installation
Heat Pump
Uses ambient air to heat water and usually runs on less electricity than a standard electric tank. Rebates may apply in NSW.
Heat pump systems and installationHow it works
From first call to hot water back on
The same four steps apply whether you are replacing a failed unit or planning an upgrade.
-
Tell us what is happening
Call or send an enquiry with your suburb, the type of system you have and what it is doing. Photos of the unit and its data plate help a great deal.
-
We scope and quote
We confirm whether the job is a repair, a like-for-like replacement or a change of system type, then quote on the unit, labour and any compliance work required.
-
We supply and install
We bring the system, disconnect the old unit, install and commission the new one, and check the tempering valve and relief valve are working as they should.
-
We clear the site
The old unit is taken away, the work is tested in front of you, and you get the paperwork and warranty details for the system that was fitted.
Brands we hold and install
Six hot water brands, supplied and fitted by our own team
We carry and install these brands, and we service and repair them as well. If your existing unit is one of these, parts and like-for-like replacements are straightforward.
Why Sydney households and businesses call us
Reasons Sydney homes and businesses choose our hot water team
-
Hot water is all we do
Over twenty years working on gas, electric, solar and heat pump systems means fault diagnosis is quicker and recommendations are based on what actually fails in these units.
-
One team from quote to commissioning
You are not managing a supplier and an installer separately. The unit, the fit-off, the removal and the compliance checks sit with us.
-
Reachable when a system fails
Hot water tends to fail at the worst time. Our phone line is attended 24 hours so an emergency breakdown can be triaged rather than left until the next business day.
-
Residential and commercial work
We work on single homes, apartments, and commercial sites where hot water loss interrupts trading. Commercial scope is quoted separately.
Commercial and strata
Hot water for businesses, strata and property managers
A failed commercial system can stop a kitchen, a salon, a gym or a childcare centre from trading. We install, service and repair larger plant and multi-unit systems, and can work with building managers on access and scheduling.
Where we are typically called
- Hospitality and food premises that cannot trade without compliant hot water
- Apartment buildings and strata-managed complexes with shared or individual units
- Gyms, salons, childcare and medical rooms with high or peak-time demand
- Offices, warehouses and industrial sites needing straightforward replacement
What a commercial enquiry usually covers
- Assessment of the existing plant and whether repair or replacement is sensible
- Sizing for the actual demand rather than the size that happens to be there now
- Access, isolation and timing so downtime lands when it hurts least
- Documentation for the building owner, managing agent or tenant

What affects the price
What we need to know before quoting your hot water job
Hot water quotes vary for real reasons, not arbitrary ones. These are the factors that change the figure, and the ones we ask about first.
| Factor | Why it matters | What helps us quote faster |
|---|---|---|
| System type and size | A continuous flow unit, a storage tank and a heat pump are different units with different installation requirements. | The brand, model and capacity from the data plate on your current unit. |
| Like for like, or a change of type | Swapping electric for heat pump, or storage for continuous flow, can involve electrical, gas or drainage changes. | Tell us if you want to stay with the same type or are considering a change. |
| Location of the unit | A unit in a tight side passage, on a roof, or up stairs takes longer and may need extra access equipment. | A photo of the unit and the space around it. |
| Condition of existing connections | Old valves, perished flexible connections or non-compliant tempering valves usually need replacing at the same time. | The approximate age of the system, if you know it. |
| Repair or replace | An element, thermostat or valve fault is a repair. A corroded or leaking tank is not worth repairing. | What the unit is actually doing, including any error code shown. |
| Rebates and incentives | NSW energy programs can apply to some efficient systems and change what the upgrade costs you. | Ask us whether the system you are considering is eligible. |
Common questions
Hot water questions we are asked most
We supply it. We hold gas, electric, heat pump and continuous flow systems from Rheem, Rinnai, Dux, Aquamax, Thermann and Evoheat, and our licensed team installs what we supply. You are welcome to discuss a unit you already own, but the usual arrangement is one quote covering the system and the installation together.
Book the repair enquiry and describe the symptoms. Many faults are an element, thermostat, valve or ignition problem and are worth repairing. A tank that is leaking from the body, or a unit well past its expected life, is usually better replaced. We will tell you which situation you are in before any work is committed.
Often yes, and it is one of the more common upgrades we are asked about. Changing type depends on what is available at the property, such as a gas connection for a gas system, suitable outdoor space and airflow for a heat pump, or switchboard capacity for an electric upgrade. We check those things at quoting stage rather than on the day.
Yes. We install, service and repair hot water for businesses and multi-unit buildings as well as houses. Commercial work is scoped and quoted separately because access, sizing, isolation and timing all affect the job. Use the enquiry form and tell us the property type so it reaches the right person.
Your suburb, the brand and model from the data plate on the unit, roughly how old it is, and what it is doing now. If you can send a photo of the unit and the space around it, that usually removes a round of questions and lets us quote more accurately the first time.
