Our hot water services
Hot Water Services Across Perth
We supply, install and repair gas, electric, heat pump and solar, so there's no incentive to push you toward one type over another. The right answer depends on your household, your roof, and whether your street even has gas.
Hot Water Repairs
No hot water, leaks, pilot light or thermostat trouble, diagnosed and fixed on gas, electric and solar units, often same day. We only recommend replacement when it genuinely makes sense.
Hot Water Replacement and Installation
Sized to your household, not the number on the old label. Installed to code, usually same day for common types, and we take the old unit away.
Gas Hot Water and Continuous Flow
Storage and continuous flow, installed by licensed gas fitters: the same team, not a subcontractor. Continuous flow gives endless hot water with nothing lost to standby heat, as long as the gas line is sized correctly.
Electric Hot Water
Storage and instant units, plus element and thermostat repairs. Cheapest to install, dearest to run, so it's worth pairing with a controlled load tariff or solar PV.
Heat Pump Hot Water
Draws heat from the air rather than generating it, so running costs sit closer to a fridge than a heater. Usually the strongest choice without mains gas.
Solar Hot Water
Roof or split systems with gas or electric boost. Highest upfront cost, lowest running cost, and well suited to Perth's sun. Repairs and booster servicing on existing systems too.
Tempering Valves
Required at bathroom outlets on new and replacement installs to prevent scalds. Supply, installation and replacement when they wear out.
No Hot Water or a Leaking Unit
Cold shower, lukewarm water, or water pooling under the tank? What to check, how to make it safe and when it's time to call.
Gas Fitting
Every gas hot water job is also a gas fitting job. Lines, bayonets, appliance connections and the compliance certificate, by the same licensed team.
Blocked Drains
We also find and clear blocked drains across Perth, with no call out fee to quote and a fixed price before any work starts.
Also routine: water heater installation, burst hot water systems and hot water maintenance.
Straight up pricing
No Call Out Fee, a Fixed Price, and Your Old Unit Taken Away
No call out fee to attend and quote
We come out, test the system and give you a fixed price before any work starts. If a replacement is the right call, we disconnect the old unit, take it away and dispose of it, so nothing is left sitting beside the house.
Repair or replace
Repair or Replace: The Honest Test
Age against the cost of the fix. Under eight years, a repair is almost always worth doing. Past twelve, spending several hundred dollars on a unit that will fail again within a year or two is money thrown away. Between those, it depends what's failed: an element or thermostat is cheap, a corroded cylinder is terminal.
If water is pooling under the tank, the decision's already made. Steel cylinders rust from the inside out, and once the wall is breached there's no repair. The sacrificial anode inside is what delays that. Replacing it around the five year mark often adds years to the tank for a modest cost.
You get the options and a fixed price for each, then you decide.
Compare your options
Hot Water Systems Compared
Upfront cost is only one column. The one that decides what you pay over ten years is running cost.
| System | Upfront | Running cost | Typical life | Needs |
|---|---|---|---|---|
| Gas storage | Low to moderate | Moderate | 8 to 12 years | Mains gas or LPG |
| Continuous flow gas | Moderate | Low to moderate | 15 to 20 years | Gas, adequate line sizing |
| Electric storage | Lowest | Highest | 8 to 12 years | Power only |
| Heat pump | High | Lowest of the electric options | 10 to 15 years | Airflow, tolerance for some noise |
| Solar with boost | Highest | Lowest overall | 15 to 20 years | Roof with the right aspect |
Gas, LPG or electric
Which System Suits Your Perth Home
The first question is whether your street has reticulated natural gas. Much of Swan View, Stratton, Bellevue and Midland does. A good deal of Mundaring, Glen Forrest and the higher hills doesn't, and those homes are on bottled LPG or fully electric. That single fact rules a lot of options in or out.
With mains gas, gas storage or continuous flow is usually the lowest total cost over the unit's life. Without it, a heat pump is normally the strongest choice. Straight electric storage still suits small households, holiday homes, or a genuinely tight budget.
Sizing and placement
Getting the Size and Placement Right
Size for the household, not the old label
Three questions matter most: how many people, how many bathrooms, and whether everyone showers in the same hour. Winter makes undersizing obvious. Mains water is colder through June and July, so a storage system that was borderline in summer runs out. That's not a fault, it's sizing.
Replacing like for like is not always right
Putting back exactly what was there is quick, but often wrong, because the household has changed: children have arrived or moved out, a bathroom has been added, or solar panels have changed the economics of a heat pump. Many units we replace were undersized from day one, so we ask about the household first.
Where the unit goes matters
- Heat pumps need clear air around them and make a low hum. Keep them away from bedrooms and neighbours' windows.
- Storage units want to sit close to the busiest bathroom. Every extra metre of pipe is water and heat wasted.
- On a sloping hills block the relief drain must not discharge against a footing.
- Solar collectors need a north facing roof with minimal shading. Mature gums can rule this out.
Done to code
Compliance, Safety and What the Paperwork Is For
Hot water in Western Australia sits under plumbing and, for gas units, gas fitting regulation. Gas installations have to be notified to the regulator on completion. We're licensed for both, and you get the compliance certificate.
None of that is box ticking. Stored water is kept at 60°C or more to control Legionella, and the tempering valve limits bathroom taps to 50°C on new installs because scald injuries happen in seconds. If you've bought a home with a gas unit of unknown history, a compliance check before winter is worth doing.
Before you call
Check These Before You Call
Two minutes here means we arrive with the right part.
- Read the label on the unit: brand, model and capacity in litres. If it needs replacing, that's what lets us bring the right one same day.
- Check the switchboard. Electric systems sometimes just trip a breaker. If it trips again straight after resetting, stop, that's a fault.
- Look underneath the tank. Any pooling water means the cylinder has gone.
- Check the pilot on older gas units. If it won't stay lit, it's usually the thermocouple.
- Note whether it's all outlets or just one. One tap is a tap problem. The whole house is the system.

I recently had Lush Plumbing & Gas re‑install the plumbing pipes in my home due to a leak, and they also replaced my old hot water system with a new instantaneous unit. The quality of their work was outstanding, everything was completed neatly, professionally, and with great attention to detail.
The pricing was very reasonable, well below the average for this type of work, which was a pleasant surprise. Luke and Zane were incredibly kind, respectful, and highly professional throughout the entire process.
I’m extremely happy with the results and confidently recommend Lush Plumbing & Gas to anyone needing plumbing or gas services. Truly a 5‑star experience.
Lush plumbing came out to my house and put in a new hot water heater for me. The worker Ali that came out was very nice to me and explained how everything in the job would go. Did a great job and would recommend
Excellent job installing hot water heat pump unit , highly recommend, very professional

Questions answered
Hot Water FAQs
Can you replace a hot water system the same day?
Usually, for common sizes and types. Call early, read us the brand, model and capacity off the label on the unit, and we'll bring the replacement with us. Less common systems, or a change from one type to another, can take a little longer to source, and we'll tell you that up front.
Should I repair or replace my hot water system?
Weigh the age of the unit against the cost of the fix. Under eight years, a repair is almost always worth doing. Past twelve, replacement usually makes more sense. If water is pooling under the tank, the cylinder has rusted through and can't be repaired. Either way, you get a fixed price first.
How long should a hot water system last?
Electric and gas storage units typically last 8 to 12 years. Continuous flow and solar often last 15 to 20, and heat pumps around 10 to 15. Whether the anode was ever replaced makes a real difference to storage tanks, and it's a cheap job compared with a new unit.
My hot water's gone lukewarm, not cold. What's wrong?
Commonly it's a failed lower element in an electric unit, or a tempering valve at the end of its life. Both are repairable, and neither needs a new system. If the water has slowly got cooler over a couple of years with no other fault, the tempering valve is the likely suspect.
I don't have gas. Is a heat pump worth it?
Usually, yes. Running costs are far below electric storage and a heat pump works with or without solar panels, because it draws heat from the air. It needs airflow around the unit and it isn't silent, so placement matters. Under a bedroom window is a poor choice.
Do you work on LPG systems?
Yes. Much of Mundaring, Glen Forrest and the higher hills isn't on reticulated gas, and those homes run on bottled LPG. We're licensed for LPG as well as natural gas, so we can repair and replace gas hot water systems on either supply.
Can you install a unit I've bought myself?
Yes, though we'll check it's the right type and size for your household first, because undersizing is the most common mistake we're called to fix. Manufacturer cover can also differ on customer supplied units, so it's worth checking that with the retailer before you buy.
Do you charge a call out fee?
No. There's no call out fee to attend and quote. We test the system, explain what's wrong and give you a fixed price before any work starts. If you'd rather not go ahead, you don't pay anything for the visit.
Do you take away the old hot water system?
Yes. On a replacement we disconnect the old unit, take it away and dispose of it, so you're not left with a rusty tank beside the house. You get a fixed price before any work starts, and there's no call out fee to attend and quote, so you know where you stand first.
What areas do you cover for hot water?
We're based in Swan View and cover the hills, including Midland, Stratton, Bellevue, Greenmount, Helena Valley, Mundaring and Glen Forrest, plus Perth's south east: Lynwood, Thornlie, Canning Vale, Cannington, Beckenham, Gosnells, Armadale and Parkwood. Elsewhere in Perth, call and ask.
