STAGE III
The next stage is matching the size of the radiator to the characteristics of the place where it is to be mounted observing a number
of rules i.e. the distance between the top and bottom of the radiator and the surrounding surface such as the floor or the window sill.
Moreover, you should also take into account the models with proper configuration, pitch and size of the connections. The size of the
radiator should allow an undisturbed air circulation around it.
Only at this stage should you make the final choice based on individual priorities regarding extra features, decorative values, colours etc.
STAGE IV
The stage of radiator model selection meeting all the earlier established criteria and individual preferences of the user.
RADIATOR HEAT OUTPUT
The actual heat output of the radiator can differ from the values specified in the catalogue as they are dependent on the heating
system parameters – feed and return water temperature and the temperature that we aim to achieve in the heated room.
Temperature parameters are an individual feature of each installation and depend on the source of heat, it usually being a boiler in
the local boiler room (individual) or a district heat exchanger to be found in multi-family residentials. Heat pumps are also frequently
applied as heat sources in houses.

NOTE:
Proper regulation of the heating agent circulation in the installation guarantees good operation of radiators working the central heating
system.
