Important Installation Conditions

To ensure clarity and compliance, please review the following conditions that apply to all hot water system pricing listed on this page:

✅ Residential Properties Only: Prices listed apply exclusively to domestic installations. Commercial premises may have different compliance requirements and will be quoted 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).

✅ Gas and Electrical Compliance: The existing electrical or gas infrastructure must meet current legal standards. If upgrades are required for safety or compliance, additional charges will apply.

✅ Tempering Valve Requirement: Under current regulations, 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. These valves must discharge to a compliant stormwater system or an approved household drain. Discharging onto the ground is not legal and will not be performed under any circumstances.

✅ Power Point Installation (Instantaneous Systems): We can provide this service competitively if a new power point is needed to install an instantaneous hot water system. Please contact us for a tailored quote.

✅ Outdoor Installations Only: The pricing provided is for outdoor installations. Additional work may be necessary if an internal system requires replacement and will be quoted accordingly.

Electrical compliance when replacing electric hot water systems

AS/NZS 3000:2023 updates the electrical rules. Your new heater must meet them.

When do the new rules apply?

✅ The unit is relocated.

✅ The element size increases, e.g. 2.4 kW to 3.6 kW.

What must be installed?

✅ Safety switch (RCD). Protects people from electric shock.

✅ Weatherproof isolator within arm’s reach. Let anyone cut power instantly.

Who does the work?

Our restricted electrical licence covers disconnecting and reconnecting the heater only. We are not responsible for supplying or fitting the mandatory safety switch or weatherproof isolator. We will advise you of your obligations under AS/NZS 3000 and can arrange a licensed electrician to complete this work. A licensed electrician fits the RCD and isolator when required.

How much will it cost?

Budget $250 – $950 for the extra electrical work. If wiring is non‑compliant, the electrician must fix it before power‑on. This can add cost.

❓Hot Water System Frequently Asked Questions Whywait Plumbing Are Asked Every Day

We supply and install electric, gas (natural and LPG), 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.

  • 🔥 Gas systems (especially natural gas) are very efficient. Instantaneous models never run out of hot water. Gas-heated storage tanks are very efficient but require all the identical valves as an electric storage system. LPG (bottled gas) is less economical. Water pressure and correct installation are crucial.

  • ☀️ 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:

  1. Safely disconnect and drain the old unit

  2. Remove outdated pipework and fittings.

  3. Install the new system with all compliant valves (tempering, TPR, pressure-limiting, etc.)

  4. Lag all hot pipework to reduce heat loss.
  1. 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.
