1.1 Introduction Showersave QB1-21 & QB1-21C (Showersave) On average, a shower uses 60 litres of water at a temperature of between 40
and 41 °C. This shower water goes straight down the drain, wasting a great deal
of heat and energy. By running the hot water through the QB1, this heat can be
transferred to the water on its way to the boiler and/or the cold water tap of the
shower's mixer tap. The heat transfer takes place simultaneously while you
shower.
Note: The Showersave QB1-21 and QB1-21C are similar systems. The ONLY
difference is the type of waste water rotator used at the top of the heat
exchanger. The heat exchangers are exactly the same.
1.2 Showersave
The NCM (SAP) Identifier is
Showersave QB1-21 OR
Showersave QB1-21C.This is
supplemented by the Model Qualifier
denoting the system configuration
(System A, B or C). Installation
systems comprising either QB1-21 or
QB1-21C are referred to as QB1
within this document, with Model
Qualifier as appropriate. The QB1 is
2.1 m long and can only be installed
vertically. The QB1 is therefore,
generally, only suitable for heat
reclamation from shower water from
an upstairs shower.
Waste water from shower

The QB1 is connected to the shower waste. If the shower is integrated into the bath, the QB1 can be connected to the bath waste. The QB1 needs to be placed as close as possible to the shower waste water exit point.
When showering starts it takes a short time for the QB1 to respond and
contribute to heating the cold water. This means the temperature of the shower
water will continue to rise for some time. It is a requirement that thermostatic
mixer valves are used.
1.3 Description of the heat exchanger
The QB1 is made of copper.
The QB1 has a double barrier between the waste water and the potable fresh
water. The heat exchanger consists of 3 pipes. A thin-walled pipe, the so-called
lining, has been installed around the inner pipe. The minuscule space between
the lining and the inner pipe contains air. If the inner pipe develops a leak, this
becomes visually apparent as waste water will drip from the heat exchanger.
This double wall separation is in accordance with EN 1717, tested and certified
by KIWA. The system is also WRAS approved.
1.4 Standard Assessment Procedure recognition
Every QB1, when shipped is identified with a unique serial numbered label
attached to it. A second NCM (SAP) Identifier label is also supplied. The installer
must complete the Model name and Qualifier field, on the label, with the system
configuration. This label must be visible for inspection by affixing it to a nearby
service or boiler cupboard without the need for disassembly.
If the label is not visible and / or the serial number does not correspond with the
commissioning certificate that is completed, the system will not be guaranteed,
nor will it be recognised in SAP.

4.0 Installation
4.1 Overview of installation - Systems A, B & C
The inlet side of the QB1 is connected to the mains water system. The outlet
side can be installed in three different ways, that are recognised in SAP, namely:
System:
A. Combined connection to the shower mixer tap's cold water connection and
the water heater.
B. Separate connection of the cold water connection to the shower's mixer tap.
C. Separate connection of the cold water connection to the water heater.
The largest energy and CO2 saving is achieved by using System A.
The performance of all 3 systems are recognised within the SAP Products Characteristics Database (PCDB) where the relevant efficiencies can be found www.ncm-pcdb.org.uk/sap
011 Showersave – Installation Manual
Amendment date: 21/08/2017
4.2 Important notes to designers & installers
The system should be installed by a suitably qualified plumber, with system
design consideration being equally important to a correct installation. For
recognition of the QB1 within SAP, a system design checklist and certificate of
installation should be completed and signed, with copies kept for the home
information pack (homeowner), the installer and sent to Building Products
Distributors at the address below. Building Control Officers may also request a
copy. The flow chart below will assist in both the design and installation process. The design and installation processes outlined within this document are
designed to comply with Approved Code of Practice and Guidance (ACOP) L8,
which are the guidelines for the prevention of Legionnaire's disease in UK
Commercial buildings. ACOP L8 is designed to provide guidance for all
installations in public and commercial premises. It should be noted that within a
residential environment in the UK homes generally cannot comply with the
ACOP L8 as interior temperatures can frequently exceed 20⁰C.

4.3 Positioning of Showersave
The QB1 should always be placed in an easily accessible location in order
that inspection work can be undertaken. The warranty will become obsolete
if this is not the case.
The WWHRS must always be installed within heated envelope for SAP
recognition. Possible locations:
Alongside internal soil stack through which the waste water would have run
Fixed cabinet under stairs if there is sufficient height
Pre-defined and specified technical area
Always place Showersave as close to the shower outlet as possible. Long run lengths will influence the systems effectiveness.
4.4 Points of note
The Showersave can be installed in homes, apartments, hotels, hospitals,
nursing homes, etc. Also industrial companies can easily utilise the heat from
the waste water. The design checklist at Appendix B should be completed to
ensure recognition.
To be recognised in SAP the QB1 must be used in conjunction with a mains
pressure hot water system, such as a combination boiler or an unvented hot
(pressurised) water cylinder. It can also be used in conjunction with a solar
thermal system.
When installing the QB1 in conjunction with a combination boiler, ensure the
appropriate system is installed that can accept pre-heated water. Refer to the
boiler manufacturers' data sheet.
Points of note Ensure the heat exchanger is easily accessible so that it can
be easily installed and uninstalled.
Ensure that a non-return valve and a shut-off valve have been installed and that these are easily accessible.
Ensure that the heat exchanger is installed in a space in which the temperature does not normally exceed 25 °C, DO NOT INSULATE the QB1
Make sure the tap water connections are preferably made using straight thread, that no hemp is used and that the tightening moment is limited to 120 Nm.
Following installation the system should be cleaned in accordance with ACOP L8 or BS 6700 (Design, installation, testing and maintenance of services supplying water for domestic use within buildings and their curtilages).
Be aware there may be some pressure loss on the tap side when a high flow rate shower head is in use.

4.5 Typical system installation
NB: rotator for QB1-21 or Cyclone rotator for QB1-21C
Notes:
1) The rotator at the top of the Showersave may be located within the
ceiling void, depending on the height of the room.
2) The size of the boxed off unit will be no more than 2,400mm in height by
340mm in width and 240mm in depth.
3) The boxing off needs to be in accordance with the NHBC standards AD
part E.
4) The Showersave, is considered a device. The space it is installed in
should be large enough so that inspection can be carried out. Access
should be possible without too much work.
5) The cold to the base of the Showersave can come from above or from a
location on the same floor. Consideration should be given to whether the
system is being installed as System A (Normal), System B or System C.

4.6 Installation of Rotators QB1-21 & QB1-21C
The supply of waste water to the Showersave must take place a rotator which is
supplied with the system, when requested, please refer to the instructional
drawings for installation. The rotator makes the waste water rotate as it enters
the Showersave, whirling it against the side walls of the inner pipe so it flows
down the inner pipe's walls along the entire length. This is important for reasons
of efficiency. REMEMBER: if not installed correctly, and in accordance with
these instructions, SAP recognition becomes invalid.
1. Standard rotator – QB1-21
The 45° bend is attached to the top of the Showersave and angled to allow the
90° bend to point in the appropriate direction. The 40 x 50 reducer is then used
to connect to the shower waste water pipe (if 40mm).
The external diameter of the inner pipe is 50mm, so a 40/50mm reducer may be
required. Using the fittings supplied, the rotator allows connection to BS EN
1451 - 1:2000, BS EN 1455 - 1:2000 or BS EN 1566 - 1:2000 waste systems.

5.0 Maintenance & Safety 5.1 Maintenance & cleaning Generally no maintenance or cleaning is required. Efficiency can slightly decrease as a result of dirt accumulating on the inside of the Showersave. However, the waste water from the shower flows at a high speed of over 1 m/s along the inner pipe's wall. This is comparable to the water speeds in a dishwasher. The water flows through the pipe in 2 seconds and so no dirt can accumulate. To a large extent the Showersave is self -cleaning. If, for whatever reason, dirt accumulates, then a soap-based cleaning agent can be used to flush the pipe. Cleaning agents based on scouring or polishing agents are not recommended as these can stick to the wall of the pipe, reducing its efficiency. Connecting a wash basin to the Showersave is not recommended as shaving gel and toothpaste are very sticky and could adhere to the wall of the inner pipe. If the system is left to stand for more than three days it is good practice to “flush the system to drain slowly” to avoid aerosol. This can be achieved by slowly (to avoid splashing) turning on a hot water tap for three minutes. In a commercial environment, under L8, It is good practice to clean and disinfect Showerheads and hoses on a Quarterly basis. In accordance with L8, and only in commercial situations, should a risk assessment be undertaken following installation of a system/s. 5.2 Legionella risk and mitigation When no cold water is flowing up the Showersave, the temperature in the pipe
should be prevented from becoming higher than 25 °C. The Showersave may
therefore not be installed near heat conducting pipes, on warm surfaces or in
spaces with constantly high temperatures (>25°C). The cold water pipe,
connection and the outer wall of the Showersave should therefore not be
insulated.
Installing the Showersave in the way shown in the diagram System A will mean
that whenever the hot water system runs the cold water system will be flushed.
This will result in stagnation being minimised and complies with
recommendations within ACOP L8. This would be the most common method of
installation.
In instances where it is not possible to ensure a Tee at the cold side of the
shower's thermostatic mixing valve, then a “venturi” effect assembly should be
considered. This is a straightforward assembly of different pipe diameters to
ensure stagnation on the cold side is minimised.
Following installation, the system should be cleaned in accordance with L8 or
BS6700 and pressure tested. This is no difference to installing any standard
plumbing/pipe system.
019 Showersave – Installation Manual
Amendment date: 21/08/2017
If the system is installed in a non-private building, ACOP L8 recommends that all
new/modified plumbing requires a risk assessment to be undertaken in order to
comply.
5.2 Warranty The Showersave QB1-21 & QB1-21C come with a 5 year warranty.
