## 3.3. Coverage of heat losses in compartments

The heat loss in compartment Q/Φ, calculated by the program, before being used for heaters selection is a subject to following operations:

- if there are partitions in a compartment, which have been declared as heated partitions (heating floors and walls), the heat losses through these partitions are subtracted from heat loss Q creating so called „reduced heat loss” Qzred/ Φzred,

- if a compartment participates in heat losses distribution, a part of Qzred/ Φzred can be assigned to another compartment, or on the contrary, part of Qzred/ Φzred of another compartment can be assigned to specific compartment. In such way the value of required thermal power of all heaters in compartment Qexc./ Φexc. can be obtained.

Required power of heaters Qexc./ Φexc. is covered by:

- unit heaters (selected by Instal-heat&energy or Instal-therm),

- radiant heaters (selected by Instal-therm, in Instal-heat&energy is possible only the declaration of efficiency),

- receivers with imposed hydraulic resistance (for example terminals of air conditioning systems) – not selected by any program, but visible in diagram of a system calculated by Instal-therm and shown in final balance of heat, which is supplied by this installation,

- other heaters or heating systems (for example existing air conditioning or heating) – not belonging to calculated system and not shown in final balance.
