2.2 System
2.2.1 Area of use
For heating buildings acc. to EN 12831.
The boilers are designed and approved as heat generators for hot water heating systems with a permissible flow
temperatures of up to 90°C. They may be installed only in sealed systems. The max. boiler temperature for the
LogWIN is limited in the factory to 80 °C.
The resulting flow temperature depends on the relevant operating status and the line losses to the system.
2.2.2 Standards
The following European standard should be followed: EN 12828, this specifies that the following should be fitted:
a) A closed expansion tank.
b) A reliably functioning safety valve (with max. 3 bar reaction pressure) installed at the highest point of the boiler
or at a non-closable line.
c) A thermometer, a pressure gauge.
d) An automatic device for dissipating heat which will prevent the maximum water temperature in the boiler of
110°C from being exceeded. The built-in thermal safety device (heat exchanger) should always be used with
the thermal discharge safeguard.
e) A low-water cut-off: A low-water cut-off is not required for systems providing up to 300 kW nominal thermal
output, if it can be ensured that a lack of water in the system will not result in excess heating.
If the boiler is above the radiators, then a low-water cut-off must be installed.
