5.1 OVERVIEW
• Combination boiler (central heating and domestic hot water).
• TANK-IN-TANK indirect storage type domestic hot water production.
• The central heating connections are designed so that they can be
connected in all three directions, this means that the boiler can be
installed against a wall or in a corner without having to leave any
free space (Fig 3 on page 3).
• Internal two-stage temperature control thermostat, which allows
the power to be adapted according to actual heat requirements.
• The day/night function allows you to store up a volume of water at
a high temperature during cheap rate periods (at night) and use
the energy stored up in this way at peak rate times (during the
day).
• The boiler is fitted with expansion tanks, a safety valve, a
manothermometer, a water low safety device (pressure switch)
and a circulation pump.
• Etech’s boilers have an effective output of 21.6 kW for the 160
model and 28.8 kW for the 240/290/380 models. These outputs
can be adjusted either using the power limiting switch on the
boiler’s control panel or by removing the bridges from the control
terminal block.

5.2 DESCRIPTION OF OPERATION
5.2.1 THE TANK-IN-TANK CONCEPT
The Etech’s series differs from traditional hot water producers in that it
has a tank immersed in the primary fluid contained in the outer body.
When there is a temperature drop in the boiler because the central
heating system or the domestic hot water circuit needs hot water, the
internal thermostat starts up the power on the immersed electrical
resistors. The heating elements quickly heat up the primary fluid, thus
creating a natural circulation around the tank.
5.2.2 INDIRECTLY HEATING DOMESTIC HOT WATER
This circulation allows easier heat exchange between the primary fluid
and the domestic water, all over the tank surface. The corrugations on
the outer shell of the tank increase the area of heat exchange still
further and thus speed up the process of heating the domestic water.
5.2.3 EASY TO SET AND TOTALLY SAFE
With a single command, the water temperature of both the primary
circuit and the domestic hot water circuit can be set by the adjustable
thermostat situated underneath the tank in the primary circuit.
A cut-off thermostat, placed on the top of the boiler, automatically
switches off the power when the temperature of the water in the
primary circuit reaches 95° C. A manually reset safety thermostat
switches off the system if the temperature reaches 103° C.
5.3 BUILD FEATURES
5.3.1 OUTER BODY
The outer body containing the primary fluid is made of thick STW
22 steel.
5.3.2 TANK-IN-TANK TYPE EXCHANGER ACCUMULATOR
The internal tank which has a large heating surface for the production
of domestic hot water is made of Chrome/Nickel 18/10 stainless steel.
It is corrugated all the way up using an exclusive manufacturing
process and is entirely argon arc welded using the TIG (Tungsten Inert
Gas) process.
5.3.3 INSULATION
The boiler body is fully insulated by rigid polyurethane foam, with a
thickness of 70mm, with a high thermal insulation coefficient. This is
sprayed onto the tank without using any CFCs.
5.3.4 JACKET
The boiler is covered by a steel jacket which has been scoured and
phosphated before being stove finished at 220° C.
5.3.5 HEATING ELEMENTS
nding on the model, the boiler is fitted with either six or seven detachable
stainless steel AISI 304L immersion heaters.

7.1 USING THE BOILER
7.1.1 LEARNING YOUR WAY AROUND THE CONTROL PANEL
(FIG. 13)
Before carrying out any work on the boiler, switch
the power off at the mains switch fitted in the
boiler room by the electrician.
1 - ON/OFF switch (item marked 1, Fig. 13)
This must be used to switch the boiler off before carrying out any work
on it.
2 - Power selection switches (item marked 2, Fig. 13)
The control panel is fitted with two switches allowing the user to select
the boiler power according to his needs.
When only the first switch is pressed down, the boiler power is limited
to the first stage using +/- half of the power (ideal in summer). In order
for the boiler to run at full power, both of the switches must be pressed
down.
To run the boiler at full power at peak rate times, you
must activate the Booster (see point 5 below).
3 - Summer/Winter selector switch (item marked 3, Fig. 13)
“Winter” position: provides both domestic hot water and central heating
functions.
“Summer” position: The central heating circulator is switched off. Only
the domestic hot water function is provided. If there is not enough hot
water available, we recommend setting the thermostat (9) to a higher
value.
When the weather turns cold again, simply select “Winter” to reactivate
the heating system..
4 - Onpeak (item marked 4, Fig. 13)
This indicator shows whether the boiler is on day or night rate.
On cheap rate (at night): the boiler runs at full power and stores up
water at the temperature set on the control thermostat. In this case
the light is unlit.
On peak rate (during the day): The boiler is controlled by a
non-adjustable minimum thermostat (60 °C). If the temperature
drops below 60°C, the boiler starts up at low power.
5 - 1 hour Booster switch (item marked 5, Fig. 13)
This button allows the user to push the boiler up to full power for a
limited period of one hour by activating the second power level at
peak rate (during the day). To do this both of the power selection
buttons must be pressed down. At cheap rate times (at night) this
button does not do anything.
6 - Booster indicator light (item marked 6, Fig. 13)
This light shows whether the boiler is in Booster mode or not.
7 - Controller (item marked 7, Fig. 13)
Please see the enclosed instructions if you have chosen this option.
8 - Mano-thermometer (item marked 8, Fig. 13)
Reads the boiler primary circuit (central heating) temperature and
pressure directly.
9 - Thermostat adjustable between 60 and 85° C (item marked 9, Fig.
13)
Central heating systems are generally designed to operate at a
maximum of 80° C. When used at lower temperatures, a 3-way mixer
valve installed on the heating flow pipe (see Fig. 2b on page 3) allows
the temperature to be set manually or, if you decide to install a
regulator (§ 2.2.4), automatically.
We recommend that you set the thermostat to the maximum values to
get the best out of the domestic hot water system.
There is a risk of burns from hot water!
The water stored in the domestic hot water tank in the boiler can be at
a very high temperature.
In all cases, install the thermostatic mixer (Fig. 3b on page 4) on the
domestic hot water flow pipe which must not exceed 60° C.
A mixer or mixing valve at each point of use is recommended.
10 - Safety thermometer (item marked 10, Fig. 13)
When the temperature in the boiler exceeds 103°C, the manually
reset safety thermostat is started up.
11 - Boiler shutdown indicator light (item marked 11, Fig. 13)
This light is lit when the safety thermostat starts up or when the water
pressure in the boiler is too low.

7.1.2 CENTRAL HEATING SYSTEM GAUGE PRESSURE
Your boiler is fitted with a central heating safety valve, set to 3 bar, and
with a pressure gauge.
First make sure that the water in the system is still pressurised. When
cold and after the air in the system has been bled, the pressure gauge
should show a pressure of between 1 and 2, depending on the height
of the building: (1 bar = 5m / 1.5 bar = 10 m and 2 bar = 15 m).
To add water, open the filling valve (Fig. 2a and 2b on page 3).
Make sure that the drain cock is properly closed after filling and
isolate the filling circuit from the central heating circuits. Bleed the air
in the system to get an accurate water pressure reading.

7.1.3 SAFETY VALVE (CENTRAL HEATING)
(item marked 2, Fig. 2a and 2b on page 3)
A monthly inspection is recommended:
Lift the lever on the emptying device for a few seconds to ensure that
the safety valve is working properly
The water which may flow out of the
safety valve is very hot and may cause
serious burns.
The pipe discharging into the waste
water disposal system should be open
to the atmosphere.
Make sure there is nobody near the

please inform the installing engineer.
7.1.4 SAFETY UNIT (DOMESTIC HOT WATER)
(item marked 1, Fig. 3a and 3b on page 4)
A monthly inspection is recommended:
Lift the lever on the emptying device for a few seconds to
ensure that the safety valve is working properly.
The water flowing out of the safety unit
may be extremely hot.
The pipe discharging into the waste
water disposal system should be open
to the atmosphere.
Make sure there is nobody near the
flow of hot water.
If you notice anything unusual after this short trial,
please inform the installing engineer.
7.1.5 BOILER SHUTDOWN
If the red light on the control panel lights up, this indicates an operating fault.
1. Check the boiler pressure, it should be between 1 and 2 bar depending
on the height of the building.
2. Once you have checked the pressure, wait until the boiler has cooled
down before resetting the safety thermostat.
4. Unscrew the safety thermostat’s protective cap.
5. Restart the thermostat using a blade end.
6. If the system shuts down again, please inform the installing engineer.
To ensure your system operates properly, have it
professionally serviced once a year before the cold weather
starts.
