Compare Your Options
Which hot water system is right for your home?
There's no single "best" hot water system. The right choice depends on your fuel supply, household size, roof and yard space, and how long you plan to stay in the home.
| Electric storage | Gas storage | Instantaneous (gas) | Heat pump | |
|---|---|---|---|---|
| Best for | Homes without gas; simple like-for-like swaps | Homes with gas wanting fast recovery | Households that hate running out of hot water | Owners cutting energy bills long-term |
| Running cost | Highest (unless on off-peak) | Moderate | Moderate, only heats water you use | Lowest, uses a fraction of the electricity |
| Upfront cost | Lowest | Moderate | Moderate | Highest, offset by rebates |
| Lifespan | ~10 years (steel tank, anode-dependent) | ~10–12 years | 15–20 years with servicing | 10–15 years |
| Space needed | Tank footprint | Tank footprint | Compact wall-mounted | Tank + fan unit, needs airflow |
If you’re weighing up gas versus a heat pump, our guide on gas vs heat pump running costs breaks down what each actually costs to run. Not sure how big to go? See what size hot water system you need.
What Happens On The Day
How we fix your hot water
Whether it's a repair or a full replacement, the process is the same: find the real fault, give you a straight answer, then get it done properly.
Diagnose
We inspect the system on-site, including the valves and components around it, not just the heater itself, before recommending anything.
Repair or replace
A quick component fix if the system has life left. A same-day replacement, disposal included, if it's genuinely at end-of-life.
Guarantee it
Every job, repair or replacement, is backed by our lifetime labour guarantee.
Maintenance
The maintenance step most homeowners miss
If you have an electric storage system with a steel tank, there’s a sacrificial anode inside that quietly protects the tank from corrosion. It should be replaced roughly every five years. Without that, electrolysis starts eating the tank itself, which is why so many steel cylinders fail around the 10-year mark. Replacing the anode is a simple, inexpensive job that can dramatically extend the life of your system.

FAQ
Hot Water: your questions answered
Plumbing problems can be extremely frustrating. Our licensed Sydney plumbers are here to provide fast, reliable answers and solutions.
My hot water isn't working. Do I need a repair or a new system?
It depends on the age of the system and the fault. A blown-out pilot light, a failed thermocouple or a faulty valve is usually a quick repair. A steel storage tank that's leaking from the tank itself or pushing rusty water is typically at the end of its life and needs replacing. We diagnose on-site and give you a straight answer before any work starts.
How long does a hot water system last?
Electric steel storage cylinders commonly fail around the 10-year mark, usually because the sacrificial anode inside was never replaced (it should be swapped roughly every 5 years). Stainless steel tanks, continuous flow units and heat pumps can last longer with basic maintenance.
Can you replace my hot water system the same day?
In most cases, yes. We carry common replacement systems and offer 24/7 emergency hot water replacement across the Northern Beaches and North Shore. Call us early and we'll usually have hot water back on the same day.
Which hot water brands do you install?
We install trusted brands including Rinnai, Rheem, Everhot and Thermann, plus other leading manufacturers. We'll recommend the brand and model that suits your home, usage and budget, not whatever happens to be on special.
Do you do commercial hot water?
Yes. We install and service commercial hot water systems for multi-level buildings, hair salons, backpackers and larger multi-bank installations, as well as reticulated hot water systems.
