How long does a hot water replacement take?

A straight swap in the same position with the same fuel is usually the quickest version. A change of fuel or position takes longer because of new pipework, a new circuit or a base for the unit. Rebate approval steps can add time before the install, unless the Solar Homes breakdown path applies.

Can I keep my old gas unit going instead of replacing it?

Yes, while it can be repaired and safely maintained. The 2027 rule only applies when a gas water heater reaches end of life and cannot be fixed. A plumber can tell you whether a repair is worth doing on an older unit or whether the money is better spent on the replacement.

Do I need to be home when the new system goes in?

It helps. The installer may need access to the meter, the switchboard and inside taps to test the system. Being there also lets you see where the relief drain discharges and collect the certificate, manual and warranty paperwork before they leave.

Is a bigger tank always better?

No. An oversized tank costs more to buy and keeps more water hot than you use, while one that is too small runs out on busy mornings. Ask the installer to size it for the number of people and how the showers are spread through the day, and to explain the choice.

Hot water replacement checklist for Sale homes

Before you replace a hot water system in Sale, record what you have now, check rebate and discount eligibility before anyone buys a unit, and get a written quote that covers siting, the relief drain, removal of the old cylinder and the compliance certificate. Doing those steps in that order is what protects the discount and stops surprises on the invoice. The list below works whether the old unit is still running or has already let go.

Why does the order of the steps matter?

Two state programs can reduce the price of a heat pump or solar unit, and both are lost easily by doing things out of sequence. Victorian Energy Upgrades (VEU) discounts can only be applied by an accredited provider, and Energy Victoria says retrospective discounts are typically not possible once a product is bought or installed. The Solar Homes hot water rebate has to go through an authorised retailer using an eligible product. On top of that, from 1 March 2027 a gas water heater in an existing home that reaches end of life has to be replaced with an electric system, which the 2027 gas hot water rule guide explains in full.

Part 1: record what you have now

Photograph the rating label. It is usually on the side or front of the tank. Get the brand, model number, capacity in litres, fuel type and the manufacture or install date in one clear shot.
Note the fuel. Mains gas, bottled LPG, electric storage, solar with a booster, or heat pump. Write down where the gas meter or cylinders are.
Work out the age. VEU needs the system being replaced to be at least 2 years old. Solar Homes needs it to be at least 3 years old from purchase. A receipt, a plumbing certificate or the label date will do.
Count the people and the peak use. A household of five with teenagers needs a different size from a couple. Note how many showers run back to back in the morning.
Note the water supply. Town water, a rainwater tank or a bore. Tank and bore water can affect which cylinder lining is a good match, so the installer needs to know.
Photograph the spot. Show the unit, the space either side, the pipes and the nearest power point or switchboard. Include the ground below if it tends to stay wet.

Part 2: check discounts and rebates before buying

Check VEU eligibility. Use the Energy Victoria hot water page and pick an accredited provider from its list. Contact the provider before any product is purchased.
Check Solar Homes eligibility. The rebate applies to owner-occupiers under a household income cap, at an address that has not already had a Solar Homes hot water or battery rebate. The Solar Victoria rebate page has the current caps and amounts.
Follow the Solar Homes order. Talk to an authorised retailer, upload proof of eligibility, wait for confirmation and a QR code, then install within 120 days.
If the system has already failed, Solar Homes lets you install first and prove eligibility as soon as possible afterwards, but only if you go through an authorised retailer and use an eligible product. Tell the retailer up front that you intend to claim.
Ask about federal certificates. Small-scale Technology Certificates also apply to heat pump and solar water heaters and are usually built into the price by the installer.
Ask every quoting business whether its figure is before or after these reductions.

Part 3: choose the system

Know the rule for your home. From 1 March 2027, a gas unit that cannot be repaired is replaced with electric in an owner-occupied house, and a rental needs an efficient electric unit such as a heat pump or electric-boosted solar.
Pick a heat pump built for cold weather. Energy Victoria advises choosing a heat pump designed for cooler climates. Sale’s July nights average about 3 degrees, and the East Sale weather station has recorded below minus 6, according to figures quoted on Wikipedia.
Compare running costs. A heat pump draws far less power than an old element tank for the same hot water, so ask each installer for an estimate of yearly running cost alongside the purchase price.
Think about solar panels. If the house already has a rooftop solar system, ask whether the new unit can be timed to heat during the day, when your own power is cheapest.
Size for your household. Ask the installer to show how the capacity was chosen.

The heat pump hot water service page covers siting and model choice in more depth, and the hot water systems page helps decide between repair and replacement.

Part 4: plan the installation

Siting. Heat pumps need airflow, and the compressor makes some noise. Keep it away from bedroom windows and the neighbour’s fence where you can.
Relief drain. The temperature and pressure relief valve has to drain to a proper discharge point. Ask where it will go, especially if the ground beside the wall is already damp through winter.
Tempering valve. Ask whether one will be fitted to limit the temperature at bathroom outlets and whether it is included in the price.
Power. A heat pump or electric storage unit may need a new circuit. The quote should say who is doing the electrical work and whether it is priced.
Gas side. If a gas unit is being disconnected or replaced with another gas unit before the rule starts, the gas work needs a licensed gasfitter.
Old unit. Confirm the old cylinder will be removed and disposed of.
Frost protection. Ask how exposed pipework will be lagged on a south-facing wall.

Part 5: get the paperwork

Written quote. Make sure it names the model, capacity, fuel, discount treatment and every item above.
Licence check. Look the plumber up on the BPC register before you accept, as the about page describes.
Compliance certificate. Hot water replacements usually exceed the value at which a licensed plumber must issue one, and gas appliance work needs one at any value. The plumbing compliance certificate guide has the detail.
Warranty and manual. Keep the warranty card, the installation manual and the rebate paperwork together.

What does a replacement usually cost in Gippsland?

The 2026 Gippsland guide on the plumbing costs page puts a replaced hot water system at $1,400 to $5,100 per system, depending on the type, position and supply. Gas fitting to connect or replace a gas unit is listed separately at $300 to $800. Electric storage in the same spot usually sits at the bottom of that range and heat pump or solar toward the top before discounts.

What will a careful installer refuse to skip?

A plumber who does this properly will want the rating label details before quoting, will not leave the relief drain running onto a path or against a footing, and will issue the certificate even if you say you do not need it. Expect them to decline to fit an unsuitable product just because it is cheaper, and to ask where the water comes from if you are on a tank. The installer you deal with through this site is an independent local business, which sets its own price and scope.

What is different about doing this in Sale?

Three local conditions change the checklist. Winter nights are cold enough that a heat pump’s output in July matters more than its brochure rating, so ask for the low temperature figure. In an older weatherboard house the existing tank may sit in a laundry cupboard or a narrow side passage, which limits which replacement units physically fit and may push a heat pump outside. And on farms around Maffra or Stratford running off rainwater, the installer needs to know the water source before choosing the cylinder.

If you have your label photo and age in hand, start a hot water replacement enquiry now rather than waiting for a cold shower.

Next step

Your enquiry needs: the label photo, the fuel type, the age of the unit, how many people live in the house, whether you are on town water or a tank, a photo of where it sits, and whether you are an owner-occupier or a landlord. Tell the provider if the unit has already failed. Then get a hot water replacement quote for your home and a licensed local plumber will reply with its options.
