ratiotherm is the specialist for intelligent storage and useful distribution of heat from arbitrarily energy sources. The modern development in heating installation is increasingly dependent how it succeed, alternative energies (for example the sun and wood or flow) ideal to use and additionally to improve the efficiency factor. A future-proof system combines the advantages of different heat generators as any kind of heat is adopted purposeful. The so far unused potential doesn´t dues to the energy extraction but to the intelligent storage and useful distribution of heat. ratiotherm has anticipated this futuristic development and designed the thermohydraulic layer reservoir. A principle fo heat storages which leaves all other market solutions far behind. The patented thermohydraulic layer reservoir named "OSKAR" works without any controls, devices or other wearing parts. But simply based alone on the physical properties of water. This technology can be installed or retrofitted anywhere and integrates any type of heat generators. Modern heating means in the future intelligent storage and useful distribution of heat energy. ratiotherm combines vision and technology, originates useful progress in dealing with heat and develops enduring concepts for the practice, as for instance even "OSKAR MAX SOL 2" the high efficiently, solar combined hybrid heat pump.
