1.0 General Information
This Installation Manual is about installation of the Q-Blue Showersave®QB1-series. This serie contains the
Showersave®QB1-21, the Showersave®QB1-16 and the Showersave®QB1-12. The way these products work is
identical, only the lenghts of the heatexchangers differ. Because the lenghts of the heatexchangers differ also the
efficiencys and the pressurelosses differ (see points 4.0 and 4.1 of this manual).
On average, a shower uses 60 litres of water at a temperature of between 38 and 40
°
C. This shower water goes
straight down the drain, wasting a great deal of heat and energy. By running the hot waste water through the
Showersave QB1 this heat can be transferred to the water on
it’s
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.

1.1 Description of the heat exchanger
In fact the Showersave®QB1 contains three copper pipes, the wastewater pipe, the outer pipe and a pipe in
between which is connexted to the outer pipe. This is how a double barrier is realised between waste water and
tap water. The miniscule space between the pipe in between and the wastewater pipe (wastewater pipe)
contains air. If the inner pipe develops a leak, this becomes visual apparent as water will drip from the heat
exchanger. This double wall seperation is according to EN1717:2000 and is tested and approved by KIWA. This
system is also WRAS approved.
Each Showersave®QB1 has a label (see fig. 1) with printed on it a unique serial number and also technical
information. This label should always stay on the Showersave®QB1 and may not be removed. If the label is
removed or not readable garantee is no longer valid.
1.2 Safety and legionella
When no cold water is flowing up the Showersave®QB1, the temperature in the pipe should be prevented from
becoming higher than 25
°
C. The Showersave®QB1 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®QB1
may therefore not be insulated.
