2.5.2 Heat radiation
The viewing panel of the FireWIN means it is inevitable that heat will be radiated into the installation room.
The distribution of heat between air and water heating is approx. 15 : 85 % without the heat shield and approx.
9:91% with the heat shield (accessory FIRE 023).
The following should be noted:
– Heating domestic water in summer:
Heat radiation always heats up the installation room when domestic water is being heated. Although the
amount of radiated heat can be significantly reduced by using the patented heat shield (accessory FIRE 023),
it can never be totally prevented.
This means it may not be possible to rule out overheating the installation room on hot days and, above all,
during the summer months.
To remedy this, we recommend heating domestic water using an alternative system such as solar.
– Heating surfaces/radiators in the installation room:
The heat radiation from FireWIN has been reduced to the minimum necessary, therefore a corresponding
heating surface or radiator should also be installed in the installation room. Heating surfaces in the instal-
lation room are essential when the system is combined with alternative heat generators (solar, accumulator
tank or solid fuel boiler) – Fig. 4.
We recommend using thermostat heads in the installation room.
– Minimum room size:
FireWIN very rapidly provides the necessary amount of heat at very low building heat demands or in autumn/
spring. Despite the fact that the boiler quickly reduces its output to the minimum level or actually switches
itself off entirely, there will nevertheless be a corresponding amount of heat radiation into the installation
room.
This means it may not be possible to rule out overheating the installation room on hot days and, above all,
during the autumn/spring.
As a remedy, we recommend having an installation room with a minimum size of approx. 15 % of the entire
area to be heated) – Fig. 4.
