Target value for the volume of the space to be heated:
Not all spaces meet the present insulating values. According to DIN 18893, the following values can be
taken for the volume of the space to be heated:
If heating circumstances are favourable:
In less favourable circumstances:
In unfavourable circumstances:
calculate according to DIN 4701
