3 DESCRIPTION OF FUNCTIONS

INSTALLATION AND USER MANUAL

Figure 3. Schematic view of the system integration (with front connected piping)

3.1 GENERAL

The ECOScience Energy Centre is designed for domestic use and
provides a complete solution for heating and hot water.

The ECOScience Energy Centre enables you to harness and store
energy efficiently from many sources (e.g. solar energy, heat pump (air
or ground-sourced)/CHP/fuel cell or solid fuel/oil/gas/district heating).
The energy is then used to produce hot tap water and heat for radiators
or underfloor heating. It can also be used to heat a swimming pool.

The ECOScience Energy Centre comprises a system tank, an energy
central unit and a control system as standard. You can also choose
certain add-on modules e.g. solar heating system, solid fuel (water­jacketed pellet/wood stove, pellet/wood boiler), buffer tank, heat pump
and pool heating.

ECOScience ENERGY CENTRE

3.1.1 System tank

The system tank is a water-filled tank that can be connected to external
energy sources. The heat energy for producing hot water can therefore
come from several different energy sources depending on the add-on
modules you have chosen. The standard system tank also has 2 built in
electric heaters (4.5 kW each) that can provide hot tap water and heating
separately (top heater and bottom heater). You can choose how much
power (1.5 kW, 3 kW or 4.5 kW) you want the electric heaters to
contribute using the control system.

There are three temperature sensors in the system tank, positioned at
the top, in the middle and at the bottom of the tank. The water at the top
of the tank is used for hot tap water, the water in the middle supplies the
radiators and the water at the bottom is used for underfloor heating or air
ventilation heating and for pool heating.

3.1.2 Energy central unit

The energy central unit, which can be integrated into the top of the
system tank, free-standing or wall-mounted, comprises a tap water
circuit, a solar load circuit and a heat circuit.

INSTALLATION AND USER MANUAL

The energy central unit features a safety valve that opens if the pressure
in the system exceeds 1.5 bar.

3.1.2.1 Tap water circuit

The tap water circuit manages the distribution of hot tap water for the
house’s existing pipe system and is equipped with a heat exchanger.
This allows tap water to be heated quickly and means that no water is left
standing in the system, thus eliminating any risk of Legionella growth.

The tap water circuit features a mixing valve to prevent scalding.

3.1.2.2 Solar loading circuit

The solar load circuit features a heat exchanger, a circulation pump and
a bivalent valve to distribute the hot water to the right level in the system
tank.

underfloor heating. If you only have radiators or underfloor heating, the
control system coordinates the distribution of heat using a shunt valve
and a circulation pump, in conjunction with indoor and outdoor sensors.
The shunt valve mixes the hot supply water from the system tank with
the colder water from the return pipe so that the right temperature is
achieved for the water that feeds the radiators or underfloor heating. The
shunt valve is controlled using sensors that measure the outdoor
temperature, the indoor temperature and the supply pipe temperature.

If you have both radiators and underfloor heating, the control system can
only control the radiators. An external control unit is therefore required
for controlling underfloor heating. For further information contact your
Service Representative.

3.1.3 Control system

The control system ensures that at any given time, the most efficient
energy source is prioritised in order to produce the energy needed to
heat the water in the system tank.

INSTALLATION AND USER MANUAL

The control system is operated using a colour touchscreen located on
the front of the system tank.

General settings are already programmed in the control system when it
is delivered (see ‘ APPENDIX 4 - DEFAULT SETTINGS’), although each
installation will require customer-specific settings to optimise the
system. The installation engineer will do this during initial setup.
