What do hot water system installation services include?
Hot water system installation services include all the activities necessary to put a reliable, safe hot water system in your home. This involves installing an unvented hot water system, inspecting the installation area, preparing materials, installing the cylinder or tank, then making the needed connections. After the installation, your plumber can test the system for flaws and address them as needed.
Inspecting installation area
Your water heater installation begins with a thorough inspection of the spot that will house the tank and its components. Your plumber makes sure that the floor is robust enough to support the cylinder's weight and complies with established building codes and safety rules and regulations. If the allotted space is deemed insufficient for the cylinder, your plumber can help you look for an alternative spot for the unvented cylinder service.Â
Preparing for installationÂ
Your plumber makes the necessary preparations for the hot water cylinder installation. If necessary, some plumbers may offer to make an improvised platform of sturdy materials to support the tank's weight. Otherwise, you can hire a Tasker to handle all your carpentry needs.
When appropriate, your hired plumber shuts off the power, gas, and water supply before starting the job. They can take all the necessary measurements to determine the right amount of materials, then cuts and bends wires and pipes to the appropriate lengths and widths. Your plumber may also cut holes into walls or floors as needed to allow pipes or wires to run through.
Installing the cylinder
Once the cylinder's space is ready, your plumber can proceed with the unvented hot water cylinder installation. They can place the cylinder or tank onto its designated space and position. Your plumber takes care not to damage any of the components of the vented hot water cylinder or other pipes and wires in its surroundings.
Installing components and pipes
After the cylinder is in position, your specialist proceeds with attaching the appropriate pipes, wires and components like the Temperature and Pressure Release valve, expansion vessel, immersion heater, and any other pipes and valves. As with all other stages of the unvented cylinder installation, they use appropriate materials and techniques that are compliant with state safety and building regulations and industry best practices.Â
Testing the system
Your hired plumber tests the system after completing the installation. They check that each tap and shower head provides hot water on demand and flows with consistent pressure. Should variations in temperature or pressure arise, your plumber can troubleshoot the system and do the appropriate fixes.Â
They repeat this process until the hot water system works without any issues. And now that your home has hot water running through your taps, tubs, and showers, why not ensure greater warmth and comfort in every room of your home? On Airtasker, you can also hire an insulation installer who can help you cut down on bills and achieve year-round comfort.

Licensed Electrician – Hardwire Thermann Electric Hot Water System
$250
Brunswick East VIC 3057, Australia
21st Sep 2026
I'm replacing my existing gas hot water system with a Thermann 160L 3.6kW Single Element Electric Hot Water System. A dedicated electrical circuit was recently installed by a qualified electrician for a heat-pump hot water system. The circuit is protected by a C16 RCBO (4.5kA) and currently terminates at a dedicated GPO. The Thermann unit I'm installing requires hardwiring rather than a GPO, so I need a licensed electrician to connect the unit to the existing dedicated circuit. Scope of work Hardwire the Thermann 160L 3.6kW electric hot water system to the existing dedicated circuit. Replace/modify the existing GPO connection as required for the hardwired installation. Confirm the existing circuit and protection are suitable for the Thermann unit. Test the installation and provide the required electrical compliance documentation. I have a plumber booked for 8:00 am Friday and need the electrician at 9:00 am Friday, so the plumbing and electrical work can be completed together. Must be a licensed electrician. Please provide your quote and confirm availability for Friday at 9:00 am. Thanks!
Add outdoor tap, with hot water mixer and hose connection
$250
Coburg VIC 3058, Australia
21st Sep 2026
We have a gas instantaneous hot water system, right near the back corner of the house. I want to add a mixer tap with a hose connection just below it so I can run medium-warm water into the garden. Ideally, the mixer tap could be fixed at a given mix of hot & cold so I'm not always trying to get it exactly right. The gas system puts out 45°C water btw.
Installed an outdoor tap before a 3yo's birthday party. Did a great job and super quickly.

We have an aquamax 390 hot water boiler... Over the past year (prior to the past few weeks) it has gone out a few times, and we have just relit it, no major issue. But over the past few weeks it is going out every few days. I suspect it will need to replace the failing thermocouple.
5 stars. Couldn't fault ryan
Lower 80kg empty hot water service from ceiling cavity
$400
South Melbourne, Victoria
21st Jul 2026
3-4 strong labourers required – lower 80kg empty hot water service from ceiling cavity. Think it will take 20-30 mins for the group to finish this. * 3-4 people required. * Approx. 80kg. * Ceiling/attic access. * No plumbing required. * Need to lower carefully (not throw it down), there’s a new floor below, so we want to carefully lower the tank on to a cushioned floor and take it outside on a trolley
These guys were GREAT to deal with! Quick comms, problem solvers, had a plan when they arrived, made a complicated little removal job look easy, even took the rubbish away for me! Will be using them again for sure!

I have a Rinnai Solar 26 gas instantaneous hot water unit and the hot water is barely above warm. I have tried adjusting the dip switches as per the manual but it hasn't helped. I'm looking for a qualified plumber who can get hotter water out of this unit. As I have already tried the dip switches, please don't come if that is your only solution.

We would like to replace the tap for the kitchen sink as the existing one is spraying. The hot water connection to the tap also appears to have a small leak which we presume would be repaired when a new tap is installed.
Cooper did a great job replacing our kitchen tap. Would recommend and will use again
