Heat pump hot water: costs and options
Start with household hot-water use and the space available for a tank and outdoor equipment. Compare integrated and split heat pumps and ask about operating noise near bedrooms or neighbouring properties.
What to include in the scope
Budget the installed system separately from slab or bracket work, valves, electrical supply and removal of the old unit. Ask for the full GST-inclusive price and a separate line for any incentive that depends on eligibility.
Plumbing and drainage work may require a licensed plumber. Check the rules for your state or territory and whether permits are needed. Electrical work requires licensed personnel.

Build your budget
Adjust the quantities and unit rates. This is a planning tool, not an installer quote.
Use local itemised quotes as the starting rates. Freight, labour availability and minimum call-out charges can change the total by location. Enter GST-inclusive rates where available and list removal, disposal and access separately when excluded.
Ask before you accept a quote.
- Who completes the plumbing and electrical work, when will we have hot water again, and which parts and labour are covered by the warranty?
- Is GST included, and is the price fixed or estimated?
- Are removal, disposal, access and making-good included?
- What changes would trigger extra costs, and who approves them?
- What is the warranty on products and workmanship?
