For System A, connect the Showersave QB1-21 to the waste outlet of the shower tray (or bath) after the waste
trap and before the soil vent pipe (SVP). The incoming cold main then enters the bottom of the outer water
jacket, with the “warmed” water from the top of the water jacket being fed to the cold inlet of the shower
thermostatic mixer tap and the cold inlet of the boiler (or cylinder).

Installation guidance & photos
1) Install the Showersave QB1-21 vertically to a solid surface, using the 2 brackets and
10mm studs supplied.
2) Ensure the 2 push fit connectors on the waste pipe (1 x 45° and 1 x 90°) are
positioned as per the photos below, with the 45⁰attached to the copper waste pipe,
and the 90⁰onto the 45⁰elbow.
The following pictures show the correct installation of the 45° and 90° connectors
on the waste. Correctly fitting these connectors will ensure the best energy
recovery performance.
3) Using the straight through push fit connector supplied, connect the waste from the bottom
of the Showersave QB1-21 to the SVP.
4) The mains water supply is connected to the bottom of the heat exchanger using ½” BSP
parallel male fittings or 22mm adapter kit if required.
5) Only use PTFE tape to seal the thread, DO NOT USE HEMP.
6) Install an isolator to both top and bottom mains water supply. Where possible consider siting this
isolation valves in an accessible location to avoid the need for access hatches to the boxing.
7) Install a drain tap to bottom supply.

8) Connect to 1/2” BSP parallel male fitting at the top of the heat exchanger to the cold side of the
thermostatic mixer tap on the shower and the cold inlet of the boiler / cylinder (this is system A).
9) Do not wrap the Showersave QB1-21 with insulation.
10) Important –It is a SAP requirement that the
2nd SAP Identifier label supplied is applied
inside of the boiler cabinet so it is easily
visible to an energy assessor should the
home owner commission a Home Buyers
EPC report. Failure to do this can invalidate
the installation.
Once installed, the QB1-21 installation must be registered via the
Showersave App. Follow guidance on page 9.
