WARNING: "LIKE-FOR-LIKE" HOT WATER PRICES ARE A PRICING SCAM
No hot water feels awful. And that’s when people get caught.
Those unbelievably low “like-for-like” prices often hide the real cost. They often exclude mandatory safety upgrades and legal compliance work. That can put your home at risk. Then it hits your wallet later.
Whywait Plumbing never plays pricing games: You get honest, all-inclusive pricing upfront. No tricks. No shortcuts – just safe, legal, reliable hot water.
Cheaper than cheap online pricing: If the quoted price sounds too good to be true, ask what’s excluded. That’s where the “like-for-like scam” lives. This is the pricing tactic the ACCC consumer regulators warn about. It’s “drip pricing”. Part price first, real price later.
Now scroll the price guide below: Everything is supplied and installed, including all necessary compliance requirements. If you want help choosing, call us, and we’ll point you to the right option fast.
As we like to say: “Choose Whywait, and consider it done.”
What's often missing from cheap "like-for-like" quotes
❌ Temperature control safety (anti-scald protection).
❌ Legally required valves and compliant pipework.
❌ Electrical isolation or upgrades, when needed.
❌ Safe discharge pipework and correct termination.
❌ Removal and legal disposal of the old unit.
❌ Commissioning, testing, and paperwork.
In Queensland, temperature control devices are legally required in most situations. That’s safety. That’s compliance. Not an optional “extra”.

Important Installation Conditions
These conditions apply to all hot water system pricing on this page. They protect your home. They also protect you from “cheap quote” surprises.
✅ Residential pricing only: Prices listed are for domestic installations only. Commercial sites often need extra compliance work. We’ll quote commercial jobs separately.
✅ Installation Assumptions: Prices are based on the assumption that the new hot water system is installed in the exact location and is comparable in size and type to the previous system. All installations are performed to meet current standards, including AS/NZS 3500.4:2025 Heated Water Services and the Plumbing & Drainage Act 2018 (QLD).
✅ Electrical services must already be safe and compliant: The existing electrical infrastructure must meet current legal standards. If upgrades are required for safety or compliance, additional charges will apply. We’ll explain why. We’ll determine the price before work begins. No surprises.
✅ Tempering valve safety requirement: Tempering valves are mandatory on all replacement hot water system installations to ensure safe water temperatures.
✅ Relief and expansion valve drainage compliance: As required by QBCC and AS/NZS 3500, all installations must include relief and cold water expansion valves. Hot water safety valves must drain to an approved discharge point. We don’t run valve drains onto the ground as a “quick fix”. That’s messy, unsafe, and often non-compliant.
We do it properly, every time. (You’ll see this shown in QBCC guidance for electric hot water installs.)
✅ Power point installation for instantaneous systems: Some instantaneous systems need a nearby power point. If one is required, we’ll tell you straight away. We can arrange a licensed electrician where needed. You’ll get the cost before anything happens.
✅ Outdoor installations assumptions: Catalogue pricing is based on standard external installation. Instant electric systems may be installed internally in standard conditions. Indoor storage units, tight access, or non-standard work can add cost. We’ll flag every extra before we start. Always.
Electrical compliance when replacing electric hot water systems
Electrical work must comply with the Wiring Rules (AS/NZS 3000:2023), including any applicable amendments.
When upgrades are often required
✅ The unit is relocated.
✅ The electrical load changes (for example, a larger element).
✅ Existing wiring or protection is non-compliant.
✅ An RCD (safety switch).
✅ A compliant weatherproof isolator, located correctly.
Who does what
✅ Our restricted electrical licence only covers disconnecting and reconnecting the heater. We don’t install new fixed wiring devices under that licence.
✅ If upgrades are required, we will advise you. We can also arrange a licensed electrician to complete the work.
Cost guide
✅ Budget $250–$950 for common electrical upgrades.
✅ If wiring is unsafe, it must be corrected before power-on.
✅ That can add cost, and we’ll talk you through it.

❓Hot Water System Frequently Asked Questions Whywait Plumbing Are Asked Every Day
We supply and install electric, continuous flow, solar, and heat pump hot water systems. Each has advantages depending on your water usage, budget, and property setup.
- 🔌 Electric systems are the most affordable upfront. Larger systems on the T33 tariff can be economical, but smaller systems on T31 can lead to higher power bills. Note: Recovery times once the tank is empty take 30–60 minutes, depending on element size and tank capacity.
- ☀️ Solar systems offer positive long-term savings if you stay home for 7+ years. However, if hot water runs out without sun, you’ll have to wait until the booster kicks in overnight.
- 🌬️ Heat pumps use up to 75% less energy than electric models but come with a higher upfront cost and ongoing maintenance. Heat pump systems require storage tanks and are very efficient but need all the valves identical to those of an electric storage system. They may not be ideal for everyone.
Depending on the availability of your chosen unit, we can offer same-day installation across the Gold Coast, but in most cases, we aim for replacement by the next day. We stock a wide range of units to restore your hot water quickly.
Yes. We supply, install, and fully commission your new system to meet AS3500 Plumbing Standards and Council regulations—including all required valves and Form 4 certification with the QBCC.
We normally do the following:
- Safely disconnect and drain the old unit
- Remove outdated pipework and fittings.
- Install the new system with all compliant valves (tempering, TPR, pressure-limiting, etc.)
- Lag all hot pipework to reduce heat loss.
- Remove and dispose of your old storage tank.
And for your peace of mind we submit a QBCC Form 4 compliance certificate and pay all the fees.
Prices vary depending on system type, size, and your current plumbing setup. Call us, and we’ll help you choose the best option and provide a detailed, fixed quote.
Yes. All installations meet the Plumbing and Drainage Act 2018 and current AS3500 Plumbing Standards—including mandatory tempering valves, expansion controls, and compliant overflow discharge.
Key valves (TPR, tempering, pressure-limiting) should be replaced every 5 years. The TPR valve should be manually lifted every 6 months, and the sacrificial anode should be checked between years 5 and 7, depending on water quality.
Yes! We provide 24/7 emergency service across the Gold Coast with rapid diagnostics and immediate repairs or replacements where needed.
We’ve been helping Gold Coast families since 1976. We only use our employees who are all licensed plumbers, no subcontractors, and honest advice. We don’t just install hot water systems—we help you make the right long-term choice.
