SOLUS II combination system for maximum energy saving
The Consolar SOLUS II series is the classic example of high performance solar thermal store which supports space heating systems. Many 1000's of systems using this technology have been installed all over Europe in the last 20 years.
For one or multi family house, a villa or a hotel – this versatile system can be integrated anywhere. It is possible to combine the system with all types of heating systems, including existing or new oil, gas, or wood and wood pellet boilers, and also heat pumps. Read more....
 SOLUS II - how it works
The design of the Solus 11 thermal store will provide immediate domestic hot water from the heat exchanger in the upper section of the store. The store can accept multiple heat inputs, solar - heating the cool water in the bottom, the internal pipe work within the store ensures the heat is delivered to
the upper region, and boiler(s) delivering heat to the centre and top regions. More than one boiler can be employed, atypical installation might include a wood stove and a gas boiler, or a batch burning log boiler. Pellet stoves or even heat pumps can be used to dealer thermal energy into the store. The Solus 11 will store the heat efficiently stratifying to maintain the hottest water at the top to ensure delivery of domestic hot water. The heat energy for the heating system, underfloor, radiators, MVHR systems is delivered from the store below the boiler input. The water within the store is circulated around the heating system and boilers, and is a sealed system, therefore only sealed system boilers can be used. Newer high efficiency gas, oil and high efficiency wood and pellet stoves fitted with boilers such as the Lenius and Lohberger range are ideal. Choosing which return pipe from the store depends on the heat buffering that is required from the boiler. A gas boiler requires very little as the boiler can modulate its output depending upon demand, whereas a batch burning log boiler will require a larger buffer area to take all the heat available, otherwise it will be wasted. The solar circuit is a separately sealed circuit containing a special solar/antifreeze fluid.

Efficiency and Economy
In an independent consumer goods test the SOLUS system with the TUBO 11 CPC achieved the highest system efficiency results. No other system achieved even a closely comparable result. The TUBO 11 CPC has since been upgraded to the TUBO 12 CI, thereby giving even better results.
The high performance, patented Consolar heat-exchanger works so that solar heated water in the inflow pipe is guided to the top of the tank where it can be used immediately. This means that domestic hot water can be drawn off within minutes of the solar system working, thereby shutting down the boiler much earlier, unlike with conventional buffer stores, also more hot water can be drawn, and can be drawn continuously.
Less bulk, more performance: the system design which provides simultaneous availability of heat for both hot water and for space heating in one thermal store reduces the size of the system and saves space. Even more important is that the SOLUS thermal store only looses a fraction of the heat that a system consisting of separate buffer and solar stores does.
In order to reduce the heat losses to a minimum, the SOLUS system is fitted with patented high performance insulation. This means that if the water is not used, the store will hold its heat for several days.
Water Hygiene
The danger of the bacteria which cause legionnaire’s disease incubating in the hot water supply is practically excluded because of the low volume of the heat-exchanger.
Compatibility and Compactness
SOLUS systems are able to be combined with nearly all boiler systems, simply. The Consolar System Regulator can be used to control the boiler as well as the solar equipment if required. Using the cleverly designed system regulator it is often possible to save even more energy than when using comparable conventional heating regulators.
Environment
The Consolar system doesn’t only lead the field in the independent consumer goods test of system efficiency. The energy pay back period, that is the amount of time it takes for the solar thermal system to produce the amount of energy that was used in its manufacture, was similarly the shortest for the Consolar system - confirmation of the very efficient use of materials and the high performance capability of the system.
Manufacture, use of materials and packaging as well as environmental quality similarly achieved the result “very good”.
The Comfort Line
Good hot water amenity and particularly high energy saving is possible with the Comfort line. The Comfort line has all the same connection possibilities as the Comfort Pro range.
Comfort Pro Line
The Comfort Pro has, in comparison with the Comfort line, an extra hot water heat-exchanger, which provides an increase in the maximum withdrawal rate of the domestic hot water available to the property.
In order to achieve the highest possible energy savings the insulation of the Comfort Pro line is fitted with a special aluminium foil which further reduces heat losses. The automatic switch valve for water heated by the solar panels, saves the water either in the heating or the hot water regions of the thermal store, depending on demand.
Both lines of the SOLUS series are available with flat plate or evacuated tube collectors. |
