Solar Space Heating System COMPACT line with RATIOcompact
The Compact Solar Heating System for Single- and Double-Family Homes
COMPACT line with RATIOcompact is a fully integrated all-in-one solar heating system with a high degree of pre-assembly and fine tuned linkage of all components. We successfully launched it with a 700-liter storage tank and a 1000-liter version.

Now also with a 1000-liter buffer tank and six solar collectors for even higher heat yield.
The features at a glance:
- All-in-one compact system with highest efficiency
A thought out combination of solar collectors, circulator, freshwater unit, system controller, storage tank and hydronic distribution designed into a single attractive looking unit.
- Get solar heat from the roof
RATIOcompact harvests the solar heat from the roof and with a speed-controlled high-efficiency pump transfers it into the buffer tank RATIO.
- Heat fresh water
Domestic water is heated with the hygienic continuous flow method.
- Solar heating
Solar heat can also be used to heat rooms. By mixing it into the return flow it is transferred especially efficiently into the space heating system.
- Good-looking and space-saving
The compact design minimizes the placement space needed. The best solution for houses without cellars.
- Fast and correct installation
Thanks to a high degree of pre-assembly, thought-out connection piping and pre-installed system controller the system can be installed especially rapidly and simply.
- Growable and compatible
Up to two more heating sources such as gas or oil boilers and water-heating stoves or pellet boilers can be added on problem-free.
