The separate pressurised solar system consists of one or more solar collectors (depending on the installation and requirements), a multifunctional storage tank for hot water storage, a control unit, expansion vessel, circulation pump and all parts related to the operation of this system. The multifunction storage tank or heat exchanger can be used for domestic hot water, underfloor heating, radiators or fan coils.

It is a system where we have two or more separate circuits, one outside (primary circuit) and one or more inside (secondary circuit(s)). These two or more circuits are separated and work independently, the heat transfer takes place in the heat exchanger and not through the fluid mixture, that is why it is called an indirect system.

The external circuit with the help of the central unit controls the start of the pump when the water is heated by solar radiation in the collectors. The internal circuit(s) are separated from the external circuit(s) and can be operated independently, each being controlled separately. This system also has the auxiliary electric resistance to heat the water during periods when we need to raise the water temperature and we cannot do it with the solar collectors.

This system also has an auxiliary electrical resistance to heat the water during periods when we need to raise the temperature of the water and we cannot do it with the solar collectors. All closed circuits, collectors, underfloor heating, radiators or fan coils must contain an anti-corrosion and anti-freeze liquid (glycol). The tank is equipped with two or more separate copper coil type circuits that have the function of connecting these closed circuits. This system is ideal for connection to a heat pump or aerothermics.

Technical Details

1. The upright tank can make the water temperature to a high level. It can hot the water instantly.
2. The tank inside the building, the hot water loses less energy than the normal one.
3. The heater collector and the water tank is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around.
4. Back up with electric heater so that in the day without sunshine hot water can also be used.
5. Can be combined with gas or electric heater.
6. Max. Pressure: 12bar; Operating Pressure: 6 bar.
7. It can be used for other function, such as waring.

Working principle

The collector absorbs solar energy and transmits it to the water tank through circulation. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically. The circulation pump makes heat-conducting liquid circulate automatically.
