A simple modification of an existing cast-iron DAKON FB 3 - 10 segments solid fuel boiler will bring you comfortable, automatic operation for hot water boilers of up to 90 kW output. After conversion the boilers can also be used with the original fuel. The boilers become combination boilers with manual feeding and automatic operation.
The conversion consists of placing the boiler on a base 44 cm high and connecting a burner on the left or right side of the boiler in such a way that access to the boiler will not be blocked. First, an opening is cut in the bottom of the existing boiler, and the heating then takes place under the actual grate of the boiler. The incandescent gases that rise up then heat the entire boiler body. The big advantage is the option of heating with solid fuel or switching to automatic mode.
The fuel feeder is controlled by an electronic unit with a temperature sensor which monitors the desired temperature of the boiler and the central heating against the pre-set values on the control unit. It can also be connected to an external room thermostat and can thus be regulated directly from a room. You can then enjoy comfortable warmth.
Another advantage is the connection of the central heating pump to a temperature sensor. The device also includes a sensor to guard against back-burn. The system offers additional protection against back-burn in the form of a hermetically sealed storage container and a sprinkler system that can be connected up. It consists of a cannister with water and a wax plug.
The boiler DAKON FB 4-7 segments will have the same emission class after conversion, as the universal burner operates only as an additional device. Following installation of the conversion package, some boiler types can obtain a higher emission class and a new sticker for emission class 4.
The feeders can be extended to any length.
