A quick conversation about your household, usage and the existing unit (a photo of its label helps)
- 02
On-site diagnosis of the tank, valves, controls and connections within licence scope
- 03
A straight recommendation: repair, or replace and with what
- 04
Installation with the required tempering valve and compliance paperwork completed
What you receive
- A clear quote before work starts
- Removal of the old unit on replacement
- Hot water at a safe 50°C at bathroom outlets, as required

Scope and limits
Electrical connection of electric and heat pump units must be done by a person holding the appropriate electrical licence. Solar collectors depend on safe roof access and suitable roof orientation.
Side by side
Which hot water system is right for you, for a Gold Coast home?
Typical trade-offs at a glance. Your tariff, roof, gas supply and household size decide the final answer, and we'll check those on site.
| System | Upfront cost | Running cost | Typical life | Best for |
|---|---|---|---|---|
| Electric storage | Lowest | Highest (lower on off-peak tariff) | ≈ 10–15 yrs | Simple like-for-like swaps, units and smaller homes |
| Gas continuous flow | Moderate | Moderate | ≈ 15–20 yrs | Homes with gas connected; endless hot water on demand |
| Heat pump | Higher (STC discount where eligible) | Very low | ≈ 10–15 yrs | Cutting electricity use; pairs well with rooftop solar PV |
| Solar (boosted) | Highest (STC discount where eligible) | Very low in QLD sun | ≈ 15–20 yrs | Good north-facing roof space; long-term owners |
Repair or replace?
Signs your system is near the end.
- Water from the tank base, or a constantly dripping relief valve
- Rusty or discoloured hot water
- Running out of hot water sooner than before
- Rumbling, popping or new noises from the unit
- A gas unit that keeps losing its pilot or showing error codes
- A system over 10 years old that is starting to show any of the above
Quick sizing guide
| Household | Electric (Tariff 33) | Gas continuous flow |
|---|---|---|
| 1–2 people | ≈ 125 L storage | ≈ 12–16 L/min |
| 3–4 people | ≈ 160–250 L storage | ≈ 16–20 L/min |
| 5+ people | ≈ 250–315 L+ storage | ≈ 26 L/min+ |
A guide only. Night-only off-peak (Tariff 31) needs a larger tank; heat pump and solar sizing differs again.

When it fails
Hot water replacement on the Gold Coast: what happens
When a hot water system fails, the first job is making it safe: turn off the cold water valve to the unit and its power or gas if it's leaking. Then send us a photo of the label (brand, model and litres) and one of where it sits. For a like-for-like electric or gas swap that's usually enough to quote without a visit, and the replacement can often go in quickly when the unit is in stock. Heat pump and solar changes need a short sizing step first, so we'll quote properly rather than rush it.
On the day we isolate and drain the old unit, install the new one with a tempering valve so bathroom outlets stay at or below 50°C, fit the relief valve drain correctly and test everything. We remove and dispose of the old unit. Electric and heat pump connections are done by an appropriately licensed electrician; gas units are tested and come with a gas compliance certificate. You get the manufacturer's warranty paperwork and a copy of the compliance notification.

Costs and incentives
Hot water rebates and running costs in Queensland
STCs (federal). Heat pump and solar water heaters can create Small-scale Technology Certificates under the federal Small-scale Renewable Energy Scheme. In practice the installer takes their value off the price. The amount depends on the model and your postcode, and it reduces each January until the scheme ends in 2030.
Queensland rebates. The Queensland Government's Climate Smart Energy Savers rebate for hot water closed in 2023, and there is no current state rebate for hot water. Be wary of quotes that include one. If a new program opens, we'll update this page.
Tariffs 31 and 33. Electric and heat pump systems on the Gold Coast are usually connected to a controlled-load tariff on the Energex network. Tariff 31 runs overnight only and needs a larger tank; Tariff 33 is available for most of the day. Your retailer sets the rates, so check your bill. With rooftop solar, heating water in the middle of the day on your own power is often the cheapest option of all.

Questions
Hot water systems FAQs: Gold Coast
Do you replace hot water systems across the whole Gold Coast?
Yes. From our base in Parkwood we cover Gold Coast suburbs within about 30 minutes, from Ormeau to Currumbin. See our service areas page for your suburb.
How long does a hot water system last?
As a rough guide: electric storage about 10 to 15 years, gas storage about 8 to 12, heat pumps about 10 to 15, and solar and gas continuous-flow units often 15 years or more. Water quality, installation and servicing (especially the sacrificial anode) make a big difference.
Can you replace my hot water system today?
Often, for a like-for-like electric or gas swap when the right unit is in stock. Heat pump and solar changes usually need a short sizing and quoting step first, so we'll give you a fast quote rather than a rushed install.
Do you do after-hours or emergency hot water call-outs?
No. We work Monday to Friday, 7am to 5pm, with Saturdays by arrangement. If your hot water fails outside those hours, call and leave a message or send the quote form, and we'll book you into the first available slot. In the meantime, if the system is leaking, turn off the cold water valve to the unit and switch off its power or gas if it's safe to do so.
Which system is cheapest to run?
It depends on your household, tariff and roof. A heat pump uses roughly a third to a quarter of the electricity of a standard electric element for the same hot water, and solar can cut boosting a lot in Queensland sun. Gas continuous flow suits homes with gas already connected. We'll lay out the trade-offs for your home.
Are there rebates?
Heat pump and solar water heaters can attract federal Small-scale Technology Certificates (STCs), which are normally taken off the price. The value depends on the system and postcode, and shrinks each January until the scheme ends in 2030. We apply the STC discount where the system is eligible and show it on the quote.
What is a tempering valve and do I need one?
It blends hot and cold water so bathroom outlets get no hotter than 50°C, which reduces scalding risk. When a hot water system is replaced, the installation needs to meet this requirement, so we fit or check one as part of the job.
Do you supply the unit, or can I buy my own?
We supply and install from major brands, or install a unit you've purchased once we've confirmed it suits your home and is compliant for installation.
