The Air Source Heat Pump estimating calculators estimate the labour and material required to fit and connect air source heat pumps from a range of different manufacturers.

Start by adding the estimating calculator with the manufacturer you’d like to use. Add a worksheet and select the air source heat pump with the appropriate heat output.

The estimating calculator will estimate the following items:

  • Heat pump
  • Wall bracket
  • Pipe and fittings
  • Shut off valves
  • Plus all labour to fit and connect the heat pump

This estimating calculator is not linked to the specifications.


  • You may wish to review the number of hours allowed for the plumber to fit and connect the heat pump.
