Winter mode: the boiler provides hot water for central heating system in the winter season. When the hot water tap is opened, the flow switch is activated by the flow of water through the switch, and by sending the command to the electronic control board, the central heating circuit is temporarily cut off and the capacity of the device is fully utilized to supply the hot water consumed. Immediately after the hot water tap is closed, the central heating circuit automatically switches ON and directs hot water to the radiators.

you have to use a cm flue duct for sealed room chamber model. It should be noted that this model of the wall-hung boiler, which combustion chamber is closed, is fitted with a special co-axial flue duct and has a fan to discharge the combustion products as well as the required air intake from the outside space. So that the air required for combustion is intaked from the outer tube of flue duct and the combustion product is removed from the internal tube of flue duct. thus does not use the inside air of the building. It is necessary to use a co-axial flue duct to install a sealed room chamber boiler.

The difference between the closed combustion chamber boiler (room sealed) and the conventional boiler is that the combustion chamber is closed and the smoke and air suction action is carried out through a special Co-axial pipe. These models are also equipped with a fan for air in taking to the boiler and to help of Co-Axial pipe to directing combustion products to the outside. In this way, the air quality of the installation site is also maintained. it is possible to install these models with a separate flue pipe and a ventilator instead of a Co-Axial flue duct.
