The Waste Water Heat Recovery System estimating calculator estimates the labour and materials required to fit and connect waste water heat recovery systems.
There are options to fit a vertical waste water heat recovery system, which wraps around the waste pipe, or a horizontal waste water heat recovery system, which sits underneath the shower tray.
Add either the Vertical or Horizontal Waste Water Heat Recovery System worksheet to estimate the following items:
- Waste water heat recovery unit
- Copper pipe and connectors
- Double check valve
- Service valve
- Plus, all labour to fit and connect the waste water heat recovery system
This estimating calculator is not linked to the specifications.
Notes:
- You may wish to review the number of hours allowed for the plumber to fit and connect the waste water heat recovery system. You can do this using by opening the estimating calculator and changing the number of hours in the Quantity per item column.
- You may also need to review the length of pipework required, in the same way.
