Solar Heating

Rotex Solaris - Solar energy for heating and hot water

ROTEX Solaris is an unpressurised and direct Drain-Back solar system

It is based on a storage tank concept which is fundamentally different from usual systems. As a result of its special structure, the system is virtually maintenance-free and fail-safe.

ROTEX Solaris uses the free power from the sun for water heating and effectively supports the heating system.

  • Unpressurised and direct Drain-Back solar system
  • Solar energy for hot water and heating
  • High perfoming flat solar panels
  • Highly effective stratified storage tank
  • Without anti-freeze agents
  • Optimum water hygiene

Solar heat - Free energy in the right place

At its peak, 80% of solar energy can be converted into usable heat. In conjunction with the quick direct storage of the heat in the ROTEX Sanicube Solaris hot water storage tank, the enormously high thermal efficiency of the ROTEX Solaris flat solar panels guarantees a high energy yield even with relatively short radiation.

It was against the background of these requirements that the ROTEX Solaris was developed and a completely innovative solar system created. ROTEX Solaris uses solar energy for water heating and effectively supports heating.

If the solar heat is not consumed immediately, the ROTEX Sanicube solar storage tank can store large volumes of solar heat and it is possible to use the heat foe hot water or heating hours later or even the next day.

  • Solar energy use for hot water and heating support
  • Maximum energy use through an optimised complete system
  • High.performance flat solar panels (flexible use through 3 sizes)
  • Variable assembly either on or in the roof or on stnads on flat roofs
  • High Storage tank capacity and very low storage tank losses
  • Optimum temperature stratificatoin in the storage tank increases solar use
  • Doubly environmentally friendly by not having to use anti-freeze agents and by avoiding the use of materials which are harmful to the environment
  • Easy to incoporate in existing heating and hot water systems
  • Solar storage tank optimum for water hygiene (tested by the Hygiene Institute in Tubingen University)
  • Storage tank and solar system maintenance-free
  • Fail-safe because no expansion tank or safety valve are required
