The operation with water:
- allows easy, direct connection to the in-house heating network,
- requires less equipment such as heat exchangers, de-aerators, valves, pumps and others
- is the precondition for the use of efficient and small storage tanks,
- eliminates the high costs for antifreeze and the associated running costs,
- considerably reduces the costs and time for commissioning and repairs,
- ensures a long operating life with almost constant performance,
- removes all risks associated with thermal stagnation and- minimizes running costs (e. g. maintenance).

Main barriers to large-scale systems
High temperatures for process heat cannot be achieved with flat plate collectors.
Solar input with “summer collectors” is far too low and economically inefficient.
Most large-scale systems constructed till now outside of Paradigma competence work badly or not at all.
Operators shy away from ageing and replacing of the heat transfer medium.
Difficulties and complexity grow with the size of the system.
Ideal solution - large-scale solar energy systems according to the Aqua principle

LSS Large-scale Solar-thermal Systems
The advantages of the AquaSystem in LSS- The solar system works like an additional boiler with freely selectable temperature.
- Solar heat exchanger, antifreeze and additional fittings are not necessary. This reduces the costs enormously.
- No more overheating problems! Process heat collection up to 130 °Cis possible with this. The system can be placed in a standstill condition withoutreservations. This allows the use of a smaller, more efficient tank.
- An outstanding thermal stratification in the tank and a minimum tankstorage requirement ensure extremely fast availability of the solar heat.
- Compared to conventional operation, approx. 50 % of pump running time and pump energy is saved over the year.
- The comprehensive functional monitoring of the controller discovers and signals faults immediately, this ensures optimal operation.

What are the risks?
• Falling energy costs – very unlikely
• No more state subsidies – interest approx. 2 % less
• Failure of the LSS – reduced to a minimum by functional monitoring / yield guarantee from Paradigma
• The sun shines no longer – then we humans will have other things to worry about
