Water heaters and boilers in Australia

Installed prices for water heaters and boilers in Australia are quoted per job, because the unit, the site and the connection all change the cost, and our current data has no confirmed price range for this category. What we can confirm is warranty terms: 1 year on parts and labour from one major brand, with longer cover on the tank. A request on BlaBlaPrice gets offers from sellers for your address and budget.

  • heater type: gas, electric, solar, heat pump or continuous flow
  • volume in litres and power in kW
  • fitting: replacing an old unit or a new connection
  • features and the make and model you prefer
  • installation, and whether the site is a house or an apartment
  • site address and your budget in A$

Warranty and proof of installation

Warranty periods are the most useful figure to compare. Rinnai offers 1 year parts and labour, with an 8-year guarantee on the inner cylinder, and Stiebel Eltron extended residential cover on its 3-phase electric instant units to 7 years from 1 July 2023. Warranties often start from the installation date, so keep the installation invoice. Some electric continuous-flow units are covered only where water quality stays within limits, so note whether your water is hard.

Rules for installation in Victoria and beyond

In Victoria, new rules require at least five years of defect cover for certain new water heating products, counted from installation, purchase or supply. The national handbook on warm water systems covers design and installation, so ask your installer which standard they follow. Gas and plumbing work must be done by a licensed trade, and you should ask to see the licence before work starts.

Season: when to replace

November is late spring, a good time to plan a replacement before the cold months from June to August. Summer from December to February gives solar systems the most sun, which is when they work best. Solar tanks and collector panels are often warranted for five to ten years, while valve work has its own, shorter period.

BlaBlaPrice is free for buyers. You describe the job in the chat, and the AI asks for missing details such as the site and water quality, then looks through sellers' websites and price lists in your country and shows the prices and businesses it found. Registered sellers reply with their own installed price and warranty terms, and your contacts stay hidden until you decide. Related trades are in Plumbing and Heating.
