ThermoCYCLE - Forstner Speichertechnik GmbH

How does ThermoCYCLE ® work?
Warm grey water
(Wastewater from bath, shower,
washing machine… no wastewater
containing faeces, oil or fat).
In a separate wastewater supply pipe ➀ the warm
grey water (from the shower, the washing
machine...) feeds through the ThermoCYCLE ® . An
ingenious filter system ➁ ensures that contaminants
in the grey water (such as hair, fluff or
sand…) are kept back. The heat exchanger ➂
extracts the heat contained in the filtered grey
water. The cooled wastewater ➃ then flows into
the sewers. The fully automatic filter cleaning system
➄ flushes out any contaminants ➅ at individually
definable intervals, also feeding them into the
sewers. This ensures smooth operation without
disruption. A bypass ➆ also ensures guaranteed,
smooth flow.
FORSTNER ® Hygienic Storage System
The exact stratification of the FORSTNER HS
enables maximum utilisation of the heat energy
recovered using ThermoCYCLE ® . For this reason
the ThermoCYCLE ® can only be used in combination
with this technology system.

Type selection
Three modules in different sizes are
available to cover the most common
requirement profiles (family home, multifamily
house, commercial…).
ThermoCYCLE ® 355
Flow rate: up to 40 l/min (e.g. 3-5 showers simultaneously)
ThermoCYCLE ® 450
Flow rate: up to 80 l/min (e.g. 6-10 showers simultaneously)
ThermoCYCLE ® 630
Flow rate: up to 200 l/min (e.g. 11-25 showers simultaneously)
It is also possible to use several modules in
parallel depending on the size of the system.
This information is based on experience and the exact sizing
must be considered separately for each case.
Perfect proportions
ThermoCYCLE ® requires little space
and can be easily transported
through narrow staircases and small
doors because of its slim dimensions.
This makes it particularly suited
to renovated older buildings.
The modules can be combined with
or supplemented using other residual
heat systems.

Heat Recovery Module
Heat recovery from grey water is the efficient use of heat that flows
irretrievably into the sewers without ThermoCYCLE ® .
DISSIPATED HEAT AT YOUR DISPOS
Should warm shower water get lost in the sewers?
No. Expensive heat is used again to pre-heat service water
and also for the heating system.
We take regular showers...
ThermoCYCLE ® allows the intelligent use of previously
unused energy potential.
Amortisation?
Yes. It is possible to recover up to 50% and more
energy input.

What means grey water?
Grey water is wastewater from the bath, shower, washbasin and washing machine.
It is created continuously in almost constant quantities – independently of the season or the weather.
What means heat recovery?
Everyone knows that good insulation keeps warmth
inside a building. There are other sources of heat,
besides room heat, that should not leave your building,
namely the 28°C - 40°C warm wastewater from your
shower, washbasin or washing machine … (grey
water). Unfortunately this thermal potential discharges
into the sewers all around the world.
Forstner has developed the ThermoCYCLE ® heat
recovery system in order to use this heat source efficiently.
The highly efficient process of the patented
ThermoCYCLE ® extracts valuable energy from the
grey water as it flows off. Without seperate costs this
heat is used indirectly to pre-heat service water
and/or to support the heating system.
Field of application
The ThermoCYCLE ® system can be used everywhere
where warm water flows off, as in a sports or leisure
facility, a hotel, indoor swimming pool, cam ping
site, retirement home, rehabilitation centre, familiy
home or multi-family house.

Wastewater that contains faeces,
oil or fat may not be used.
Conditions of installation
In order to use grey water you need a wastewater
pipe system that is separated from the black water
(e.g. waste water from toilets or the kitchen). This is
easy and inexpensive to realise in new buildings or
in the course of general renovations.

Thermal energy (heat) is one of
the basic requirements of
mankind and is needed in all
situations. It is not possible to
create energy, only to convert or
to save it.
For this reasons it should be a
primary aim to use our energy
(heat) more carefully, at least if
it is possible to make the decision
ourselves.
Considerable advantages:
Very high savings potential
Reduction of the emission of harmful substances
An average of 15 kWh can be recovered from 1000
litres of grey water (measured with cold water temperatures
between 8-12°C).
