2.3.2 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 heat-
ing surface or radiator should also be installed in the installation room. Heating surfaces in the installation room
are essential when the system is combined with alternative heat generators (solar, accumulator tank or solid
fuel boiler) – Fig. 2.
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 instal-
lation 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. 2.
2.3 Installation
2.3.1 Installation room
Basically, any room with normal air humidity and living space temperature in the living area is suitable for instal-
lation, providing it has a flue connection with an adequate draught (see technical data for flue requirements)
and satisfies the statutory regulations and directives.
Note: Due to the operating and flame noises, we do not recommend installing the device in bedrooms or quiet
rooms.
FireWIN is not allowed to be installed in rooms that are very dusty or humid (e.g. bathrooms, sanitary rooms,
etc.). The combustion air must be free from halogens and hydrocarbons (detergents, e.g. chlorine, ammonia,
fluorine, etc.) otherwise malfunctions may occur.
The installation room should not be too small otherwise the room could be overheated by the heat radiation.
The recommended rule of thumb is: The installation room should account for at least 15% of the area to be
heated.
2.2 Taking in
FireWIN is delivered without cladding (door, cover, side panels) on a pallet, without wood partitions. The cladding
parts are in a separate cardboard box. The taking-in weight is less than 200 kg, the taking-in width is 55 cm.
For the Installer
The boiler must be installed in dry, frost-free premises!
Limits (maximum): Air humidity: 85% at 25° room temperature (noncondensing)
Room tempe2 to 40°C
