Top connected system tank, CS300
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.
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.
