What's in the price
A fair heat pump quote should include the unit, the install, new tempering and relief valves, a proper base and drainage, commissioning, and taking the old system away. Some quotes leave out removal and disposal, which typically adds $79 to $210, so check before you compare.
What pushes the price up
- A bigger tank for a bigger household
- Converting from gas or solar rather than swapping an electric tank
- Electrical work, such as a new circuit for the heat pump
- Moving the unit to a new spot, or tricky access
- Premium models with quieter compressors or higher efficiency
Why we don't quote over the phone
A phone price rarely survives the real job. Nobody has checked your power supply, clearances, drainage or the old unit. We come out, look at what's there, and give you one all-in price in writing before any work starts, so the number you agree to is the number you pay.
Running costs
A heat pump costs more to buy than a basic electric tank, but it uses a fraction of the electricity to heat the same water, because it moves heat out of the air instead of making it with an element. If you've got rooftop solar and set the heat pump to run in the middle of the day, it can run largely on your own power.
