Heating defined as "isolated gain" is obtained by accumulating and isolating solar radiation with heat accumulators and exchanging it with living spaces or through special systems, thermo converters.

To obtain a sustainable heating system in addition to the solar walls, the roof pond and the windows facing south we could use the convention circuit in which two means are used.

  • Thermo converters, exchange heat between the storage tank and the rooms of the dwelling.
  • Thermal accumulators capture solar radiation and accumulate it in storage tanks.


Unfortunately, this system works only when the sun that warms the water is shining, and can then be stored in a well-insulated tank.

To allow this exchange between inside and outside, systems that will be subject to maintenance are required.
