The condensing wood boiler offers a higher performance than the conventional boiler. This is explained by the perfect combustion of wood pellets, thus freeing up a maximum of thermal energy. The automatic condensing wood boiler draws fuel from the silo. In contrast, the semi-automatic requires the loading of fuels from time to time. The installation must meet certain conditions. After connecting the boiler to the central heating circuits of your home, install flues and connect the boiler to the sewers.

Hydraulic circuits

The performance of the boiler will be optimal if it is fed with cold water. The configuration of the circuits must therefore take into account this condition. For this, it is necessary to feed the condenser with the coldest returns. This should avoid mixing the hot and cold water pipes.

The flues

In order to optimize its operation, the boiler must be connected to suitable flues. It is connected to two generally concentric ducts, also called suction cups. One of the ducts provides the air supply necessary for combustion while the other allows the evacuation of smoke. It is forbidden to use aluminum tubes for connection. Flexible PVC or stainless steel tubes are required for installation.

Connection to the sewage network

It is necessary to connect the condensing boiler to the sewer system to evacuate the wastewater. The use of anticorrosive ducts is recommended for connection. Condensates are relatively acidic and could damage metal pipes. To solve this problem, PVC is a solution for casings.

Tips and tricks

For semi-automatic boilers, granules purchased in bulk cost around € 200 per tonne;
The wood-fired boilers are intended for a mild heating system;
Be sure to choose the power of your boiler according to the living space.
