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. 

Preparing for installation 

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. 

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. 

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.

Repair Electric Hot Water System

$150

Taringa QLD 4068, Australia

25th Jul 2026

I have a Dux Proflo electric hot water system and it has stopped heating water. The tank is completely cold and there is no sound coming from it. The water pressure is perfectly fine, so there are no plumbing/flow issues. I have already done some basic troubleshooting safely: Checked the main switchboard. The dedicated hot water circuit breaker was NOT tripped. I cycled it off and on anyway, and it did not trip (no short circuit). Turned off the power, opened the bottom panel, and checked the Robertshaw thermostat. The red over-temperature reset button has NOT popped out. I tried pushing it just in case, but it is firmly set and hasn't tripped. Based on this, it is likely an open circuit—most probably a blown 2.4 kW heating element or a faulty thermostat. I need a licensed electrician or plumber to come with a multimeter to confirm the fault, and ideally have a spare 2.4 kW element and/or Robertshaw thermostat on hand to replace the faulty part on the spot. Location is in Taringa. Easy access to the unit. Thanks, John

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!

Replace Stolen Gas Hot Water Unit

$1,000

Rockbank VIC 3335, Australia

13th Jul 2026

Hi, I need a licensed plumber/gasfitter to replace an instantaneous gas hot water system that was stolen from the exterior wall of my property in Rockbank. Looks like the thieves cut the copper lines, causing a leak. The gas network distributor has already attended, shut off the gas at the main meter, and capped the damaged line with emergency isolation tape for safety. Scope of work includes: Supply and install a new external continuous flow gas hot water unit (standard 3-4 bedroom home). Repair/reconnect the damaged copper gas and water pipework left on the brick wall. Conduct a full gas safety/leak test. The property is currently tenanted, so coordination for access will be arranged via my real estate agent.

Was great working with Mitch thank you!
